.  March 10, 2020

Retort pouches as a daily pouch were widely used in our kitchen life. It’s a good assistant for us. For those a thousand types of retort pouches, do you really know what exactly are retort pouches? Or how’s work for our life? What’s special of the material and how’s the standard of those food packaging?

In this article, we’ll show you the answer! Let’s get to know more!

Retort pouches are a type of flexible packaging used to package food.
This type of packaging is often used for shelf-stable and sterilized products, such as soups, stews, and sauces.

Retort pouches are made from a combination of nylon, polyethylene film layers, and aluminum foil to create an oxygen-free environment that prevents spoilage

. The pouch is hermetically sealed so that it can withstand high temperatures during the sterilization process.

The sealed pouch also provides an extended shelf life for the product, making it perfect for storing foods for long periods of time. Retort food products are easy to transport and store since they don’t need refrigeration or special storage conditions.

With their convenience and extended shelf life, retort pouches have become increasingly popular among manufacturers and consumers alike.

The history of retort pouches


The idea for retort pouches was promoted by the US army in 1950 and the research continued through 1960. It was finally invented by United States Army Natick R&D Command, Reynolds Metals Company, and Continental Flexible Packaging and was first introduced in Italy. These companies received the Food Technology Industrial Achievement Award for their invention in 1978.

Change is sweeping through supermarkets. Products once used for canning can now find a home in a new packaging medium, the stable vertical packaging bag.

We have never seen so much packaging innovation in such a short period of time. Pet food manufacturers, seafood manufacturers, and other food manufacturers have begun to consider this new way of customizing food packaging to make their products more attractive to consumers. Cookable pouches offer many advantages over traditional tin cans.

These pouches faced a stagnation period in the beginning due to the reluctance of the people to accept them. However, over the years manufacturers and companies have realized that using retort pouches for packaging reaps many benefits.


 Inside of retort pouches


When we wax praises about how well retort pouches package, it is because of its internal structural composition. It has the sturdiness of metal cans and protects the nutrient value of the food. Specifically, each pouch consists of four layers as shown in the image below.



  • The first layer is propylene which acts as a heat seal surface and provides strength and flexibility.
  • The next layer which is the nylon layer protects from abrasion.
  • The aluminum layer not only protects from lights, gases, and odor but also extends the product shelf life.
  • The final polyester layer provides excellent strength and is very easy to print on.

The materials that go into the packaging of retort pouches are FDA approved and undergo sterilization processes which increase the durability of the packaging.

Material of retort pouches


The structure of the high-temperature resistant cooking bag has two layers, three layers, four layers, and even more.


Among them, the second layer is a transparent plastic/mold, such as PET / CPP or OPA / CPP.

The three layers are transparent plastic/mold, such as PET / OPA / CPP, and opaque types containing aluminum foil, such as PET / AL / CPP, OPP / AL / CPP.

The four layers are opaque PET / AL / OPA / CPP with aluminum foil. This structure is a puncture-resistant, reinforced, large-capacity packaging bag. The OPA should be reasonable between AL and CPP.

The more layers are mainly The inner layer does not use pure CPP film, but uses multi-layer co-extruded film, such as PA / EVOH / PP, PA / PVA / PP co-extruded film plus PET or aluminum foil to form a composite with more layers, but its quantity Not much.

From a functional point of view, the four-layer structure PET / AL / OPA / CPP bag containing aluminum foil can completely meet the requirements of all cooked food.

For these materials used in cooking bags, it is necessary to introduce their properties and functions. In order to ensure the quality of cooking bags, specific requirements should also be put forward.


1. Polyester film PET, also known as biaxial (or biaxial) stretch polyester film


PET (or BOPET) film is used as the outer material of the cooking bag, and its thickness is 12 μm. It has the characteristics of high melting point, high heat resistance, high mechanical strength, high rigidity, high transparency, high odor resistance, and high gas resistance. Due to the polarity relationship in its molecular structure, the surface tension is high, and it is slightly increased. The surface tension after corona treatment can reach 52mN / m (ie 52dyn / cm), which is very favorable for printing and binding.

When PET is used as the outer layer material and other heat-sealable materials (CPP, PE, etc.) are compounded to heat-seal bags, even if the temperature is as high as 220 ° C, it will not melt and deform, and will not stick to the knife. Bag making. At present, there are many PET film production suppliers in China. Most PET films can meet the high-temperature cooking of 120 ~ 128 ℃, and even meet the high-temperature cooking of 135 ℃. However, there are also some PET films with thermal shrinkage. Large, the problem of deformation after high-temperature cooking. Therefore, when choosing PET for high-temperature cooking, be sure to choose a product with a small heat shrinkage ratio, and then use it with confidence.


2. Aluminum foil AL


Aluminum foil is a metal material. Most of the soft aluminum foils with a thickness of 9 μm are used on the cooking bags. Airtight (O2, N2, CO2, etc.), opaque, and extremely high heat resistance and oil resistance, so the composite bag made of aluminum foil has a full seal (like tinplate cans), high security It has excellent properties such as oil resistance and high-temperature resistance. It is the highest-grade composite flexible packaging material.

3.Cast polypropylene CPP


In cooking bags, as the inner material that contacts food contents and heat-sealable bags, most of them are unstretched cast polypropylene films with a thickness of 70 μm to 80 μm. Only a few use high-density polyethylenes ( HDPE) Manufactured at 121 ° C.

High-temperature retort pouches – as one of the most commonly used cooking bags, its trial materials and standards may be higher. Do you know the high-temperature retort pouches?

Whats High- temperature retort pouches?


“The high-temperature cooking bag is a kind of composite plastic film bag that can be heated. It has the advantages of both a canned container and a boiling water-resistant plastic bag. Sterilized and heated, ready to eat. After more than ten years of use, it is an ideal sales packaging container.

Retort Pouch Manufacturing Process



Retort pouches are typically created through a four-step process.

First, lamination layers of material are formed into a web.

This web is then cut into individual pouches and then sealed along the edges.

The last step involves sterilizing the pouch and filling it with food or beverage products.

The lamination process is key in creating a retort pouch. It involves combining two or more layers of flexible packaging together using heat and pressure, which creates an effective barrier from external elements such as oxygen, light, grease, moisture, and dust.

This barrier helps to keep food fresh for longer periods of time without needing a refrigerator or other preservation methods.

The cutting and sealing steps involve specialized machines that can produce thousands of pouches every hour at high speeds and accuracy.

These machines use metal dies to cut the laminated web into individual pouches while also sealing their edges in one single motion.

Finally, the sterilization step ensures that all bacteria on the pouch have been eliminated before any food products are added inside them.

Retort pouches are pre-packaged food products that have been sterilized and sealed in a pouch made of plastic and aluminum.

The pouches are designed to keep the food safe and remain sterile until opened. The process of sterilization involves exposing the food to high temperatures, usually between 120°C and 132°C, for extended periods of time.

This ensures that any bacteria or other microorganisms present in the food are killed off, ensuring it is free from contamination.

The retort pouch itself also plays an important role in the sterilization process.

The pouch must be strong enough to withstand the high temperatures used during the process, but flexible enough to allow for expansion as steam is introduced into it.

Additionally, the pouch must be able to maintain an airtight seal throughout the entire process.

This helps ensure that no microorganisms can enter or escape from inside the pouch during sterilization.

The entire process of sterilizing retort pouches is strictly monitored and controlled by professionals who ensure all safety guidelines are followed carefully so that only safe, sterile food products are produced.

By following these steps, companies can guarantee that their customers receive only healthy, uncontaminated food products every time they purchase a retort pouch product.


Types of High-temperature retort pouches



Classification by structure:


Class A: PA / CPP, PET / CPP. Amount of water vapor transmission: ≤15g / (m㈠4h); Amount of oxygen transmission: ≤120cm / (m2㈠4h0.1HPa).

Type B: PA / AL / CPP, PET / AL / CPP. Water vapor transmission rate: ≤0.5g / (m (4h); oxygen transmission volume: ≤0.5cm / (m㈠4h0.1MPa).

Type C: PET / PA / AL / CPP, PET / AL / PA / CPP. Amount of water vapor transmission: ≤0.5g / (m㈠4h); Amount of oxygen transmission: ≤0.5cm / (m㈠4h0.1MPa).



 Classified by cooking temperature


When the relative pressure is 110 psi, the corresponding temperature is l15cC; the shelf life is about 3 months.

When the relative pressure is Ps 1 15 psi, the corresponding temperature is 121cC; the shelf life is about 6 months.

When the relative pressure is PS 1 20 psi, the corresponding temperature is 126cC; the shelf life is about 12 months (transparent bag).

When the relative pressure is PS1 30 psi, the corresponding temperature is 135cC; the shelf life is about 24 months (aluminum foil bag).

Of course, the shelf life has a lot to do with the barrier properties of the cooking bag and the type of food.


 Classified by sealing process


There are three main types: heat seal, double heat seal, and laser welding.

Heat sealing involves using heat to emboss a pattern onto one side of the pouch that seals it when pressed against another surface with pressure.

A double heat seal involves creating two layers of overlapping seals that provide increased strength and protection from moisture and oxygen infiltration.

Laser welding uses a laser beam to create an airtight bond between two pieces of film, resulting in an incredibly strong seal that has minimal risk of failure due to temperature changes or other external factors.

How to test the retort pouch?


(1)sealing test


Through blowing up the compressed air in the retort pouch and underwater extrusion, we can test the sealing performance of the material.

We can effectively evaluate the sealing performance to  get basis information for determining the process indicators.


(2)pressure resistance and drop resistance test


Through the test of drop and pressure resistance, you can have a clear understanding to the resistance to rupture performance and ratio during the turnover process.

Anything can happen during the transportation, you have to do the pressure test for a single package and a drop test for whole box of products.

Besides, you need to do multiple tests in different directions, in order to get a comprehensive date.

That’s how you can solve the problem of product damage due to  the transportation


(3)Mechanical strength test of retort pouchThe mechanical strength of the packaging materials include the composite peel strength, sealing strength, tensile strength, etc.,


if the test index can not meet the standard, it’s easy to break or fracture in the process of transportation.

Such parameters can be tested by universal tensile tester which meet the national and industry standards.


(4) Barrier performance test


Retort pouch are generally packed with highly nutritious contents such as meat products, etc.,

These products are susceptible to oxidation and deterioration. Even in the shelf life, its taste varies with the date, so to ensure its nutrition, flavor and quality, the packaging should use the material which are able to prevent the product from outside space.

That’s why it’s necessary for  strict oxygen and moisture permeability test


(5) Residual solvent testing


Printing and compounding are two very significant steps during the production of retort pouch the use of solvents in the printing and compounding process is necessary.

The solvent is a polymer chemical materials with certain irritating odor, which is harmful to human body.

Every countries has relative lows to control the uses of these solvents

so during the printing process of semi-finished products, composite semi-finished products and finished products production , we have to do the solvent residue tests to ensure that the products are healthy and safe.

Therefore, printing semi-finished products, laminated semi-finished products and finished products are need to be tested for solvent residues to ensure that the products are healthy and safe.


Benefits of retort pouches packaging


The retort pouch has been developed as a flexible laminated food package that needs to withstand the heat treatment.

There are many benefits to using retort to package food. Foods can be raw or pre-cooked before being put into retort packaging. Compared with traditional rigid containers, they have a faster sterilization speed and a lower temperature.

One of the main benefits of manufacturing is that processing time is usually greatly reduced compared to processing in cylindrical containers.

Other advantages are that packaging requires smaller empty container storage space, easy to package and display, and can also reduce your transportation costs.

Sachets have become very popular and have been widely accepted by consumers.

Because they are strong, light, and versatile, retort packaging has become a widely used alternative to traditional canning methods, which can be used to preserve food and keep it fresh for a longer period of time. They use less than 5% of the packaging materials of traditional hard metal cans, and they help improve the flavor, texture, and aroma of food.

The stand-up pouch is made of a special laminated layer to protect food from spills, punctures, and external contaminants, and a special film is designed for foods that require fast cooking.

The retort packaging is ideal for items such as soups, rice, sauces, and pasta. If you are looking for the best quality retort packaging that Australia must provide, please contact us immediately.

However, those kinds of retort pouches are commonly used in our life right now while they do help to save the day! Let’s see:


Due to the sturdy packaging, these pouches are protected during transportation. Being lightweight, they also prove to be very cost-effective during transit. They can easily withstand temperature variations of up to 250 degrees and are leakage-proof.




Retort pouches utilize just 5% of the packaging material and at the same time improve the food texture, flavor, and aroma. Also, the energy that goes into the production of these pouches is much less than what goes into making metal, paper, or glass packages. They are made with high-quality materials and are environment-friendly.





Retort pouches can stand upright on the shelves and this helps in maintaining the food composition inside. They are also flat and hence take up very little space on the shelf as well as in the shopping bags.


Combinedly, all of the above advantages serve to make retort pouches the go-to packaging, especially in the food and beverage industry.


8 Advantages Of Retort Pouch Packaging


The retort pouch packaging is a composite plastic film pouch that can be heat treated. It has the characteristics of both a canned container and a boiling water-resistant plastic bag. Therefore, it is also called a “soft can”.

The retort pouch is made up of three layers of materials. The typical retort pouch structure is: the outer layer is a polyester film for reinforcement; the middle layer is the aluminum foil for light, moisture, and leakproof; the inner layer is polyolefin Membrane (such as polypropylene film) for heat sealing and contact with food.

In terms of food packaging, retort pouches have many unique advantages over metal cans and frozen food pouches.

Here are the 7 major advantages of retort pouch packaging:

1. Maintain the color, aroma, taste, and shape of the food. The retort pouch is thinner and can be sterilized in a short period of time, and the original color, aroma, taste, and shape of the food are preserved as much as possible.

2. Easy to use. The retort pouch can be opened easily and safely. When eating, put the food into the boiling water together with the bag and heat it for 5 minutes to open it, even if it is not heated.

3. Convenient storage and transportation. The retort pouch is light in weight and can be stacked and stored.

4. The space occupied is small. After packaging the food, the space occupied is smaller than that of the metal can, and the storage and transportation space can be fully utilized to save the storage cost.

5. Save energy. Due to the thinner retort pouch, the bacteria can reach the lethal temperature faster when heated, and the energy consumption is 30-40% less than that of the iron can.

6. Easy to sell. The retort pouch can be packaged or assembled according to market needs, and customers can purchase it at will. In addition, due to the beautiful decoration, it also greatly increases the sales volume.

7. Long save time. The food packaged in the retort bag does not need to be refrigerated or frozen and has a stable shelf life, comparable to metal cans, easy to sell, and is convenient for home use.

8. Low manufacturing costs. The composite film for manufacturing the retort pouch is lower in price than the metal sheet, and the production process and the required equipment are much simpler, so the retort pouch is lower in price.

Lanker retort pouches are available in a variety of accessories, including easy-to-tear, nozzle, zipper, transparent window, etc., to withstand temperatures from 120 ° C to 135 ° C.

Lanker retort pouch is strictly in accordance with international standards for quality control and is certified by the SGS testing organization for BRC and ISO certification, in line with international food safety standards.


Popular uses for retort pouches packaging


You can put almost any processed food or beverage you can think of into the cooking bag. Pet food manufacturers often use them to package wet foods and snacks.

The choice that consumers can pierce with a straw is suitable for juice and yogurt drinks. They are a good choice for ready-to-eat main dishes such as curries, pasta with sauces, and other pre-cooked dinners.

Manufacturers also use these containers for soup, rice, and pre-cooked vegetables.

Pet products, including snacks and wet food

Ready to serve dinner main course selection
Soup, rice, and delicious pre-cooked vegetables


Disadvantages of distillation packaging


Retort pouch packaging has two main disadvantages: initial mechanical cost and process complexity.

It requires highly specialized filling, heat treatment, and tensile strength testing equipment. The purchase and maintenance costs of these machines are often high.

Production complexity is another potential stumbling block. In order to properly heat-treat sealed bags, manufacturers must consider several factors, including residual air and packaging thickness.

Two other potential difficulties include slower filling speeds and the need to provide additional protection during transportation. Filling technology is often slower than canning technology.

Depending on the type of container you choose, you may need to provide additional packaging during the distribution process to minimize the chance of accidental punctures.

COVID-19 scenario analysis of retort pouches


Due to the cessation of manufacturing and a significant reduction in global demand for luxury goods and non-essential services, the COVID-19 crisis may have a negative impact on the retort packaging industry.

The impact of the COVID-19 crisis on the packaging industry is mixed, mainly due to the closure of physical retail stores around the world. However, the availability of online retail has absorbed the severe effects of this shutdown.

Demand for e-commerce specific packaging is likely to remain strong, although e-commerce companies will have to focus on product protection and packaging disinfection.

In addition, the food packaging industry is at the forefront of the global packaging market, mainly due to the demand for basic products such as groceries and fresh food from local e-retail sites.

Due to the decline in demand for non-essential goods in the first two quarters of 2020, industrial, transportation and bulk packaging are facing a sharp decline.

Due to the decline in the disposable income of the largest population and the weak demand for packaging for industrial products, the packaging industry may face tremendous pressure to reduce wholesale and retail costs.

Consumers may be hesitant to spend on luxury goods, travel and hotel services, which is expected to hinder the future growth of the packaging industry after the COVID-19 crisis.

What kind of food is suitable for cooking bags


(1) Field rations

Not everyone works in the city.

There are some special workers whose work is far away from the city.

In the wild or even on the high mountains. There are no salty vegetables or food there.

They did not work there for a day or two, but several years. So, how to let them eat delicious food?

This is a very critical issue. Distillation packaging is a boon for these workers.

They can eat what they want in the city, so they are in great demand.

(2) Air food

Like the needs of field workers, aerospace workers also have problems in this regard.

The dietary needs of space workers are more difficult because they work in space.

Their food packaging requirements are higher.

The problem of being overweight must be overcome in space.

The good news is that we solved this problem.

The bag can be left on the space station to provide food for the astronauts and ensure their nutritional needs.

(3) Seafood

Many people live far away from the sea.

They cannot eat fresh seafood all year round.

Because it seems that the shelf life is only 1-2 days, or even shorter.

We know that the sooner you eat seafood caught from the sea, the better. Therefore, people living in inland areas cannot eat fresh seafood.

To solve this problem. This is a special consideration when developing retort packaging.

After the seafood is salvaged, clean it immediately and put it in a cooking bag.

And immediately carry out high-temperature sterilization treatment.

The original flavor of seared seafood. When opened again, the taste is the freshest.

(4) Camping food

More and more people want to live outside the city.

More and more people want to travel on the go.

Finding beautiful scenery in nature is a great way to relax.

But how can there be no food to accompany you on the road?

Choosing food packaged in sterilization bags is the choice of more and more wild travelers.

Bring food, bring a good mood, embrace nature, and enjoy a good time.

(5)Soups and sauces

Retort pouches are also suitable for packaging soups, broths, and sauces. These types of products can be cooked at high temperatures and then packaged in the retort pouch for extended shelf life.

(6) Vegetables

Retort pouches can also be used for packaging vegetables such as carrots, peas, and green beans. These vegetables can be pre-cooked and then packaged in the retort pouch for extended shelf life.

(7) Baby food

Retort pouches are commonly used for packaging baby food. These pouches are designed to be lightweight, easy to use, and easy to transport.

(8)Ready-to-drink beverages

Retort pouches can be used for packaging ready-to-drink beverages such as juice, tea, and coffee. These products can be sterilized at high temperatures and then packaged in the retort pouch for extended shelf life.

4. How do you use the sterilization bag

The use of distillation packaging is very simple.

If your home or company has a microwave oven, you just need to put the bag in the microwave oven.

You can enjoy the food in 2-3 minutes.

If you are outdoors, put the sterilization package in boiling water and blanch for a few minutes. For food that does not need to be heated, just open the bag to eat.


Storage Guidelines


To ensure the safety and quality of retort pouches, it’s important to store them properly. Here are some storage guidelines:

First, keep retort pouches in a dry area with low humidity levels.

This will help prevent the growth of mold or mildew on the packaging material.

Second, store them away from direct sunlight or other sources of heat, as this could cause the materials to become brittle or damaged.

Lastly, make sure they’re stored in an area that is free from dust or debris. This will help keep contaminants out of the food stored in the pouch.

By following these guidelines for storing retort pouches, you’ll be able to maintain their quality so they can be used safely for years to come.

Once a pouch has been opened, its contents must be consumed within several hours or else they may spoil and become unsafe for consumption.
