Retort - Krcpack Ambalaj | Tek - Çok Katmanlı Esnek Ambalaj

Retort packaging is a flexible laminated food packaging/bag that can withstand retort processing. Its shelf life is as long as metal cans. Retort packaging is considered the most important development in food packaging since metal cans. These packages are thought to be the best alternative to metal cans and glass jars.

Compared to traditional metal cans, retort packaging is very lightweight, which provides logistics advantages by taking up less space and being lighter. Tin cans have a constant volume, even when they are empty. Retort packaging, on the other hand, takes up very little space when empty.

The material selection is crucial in the manufacturing of retort bags that can withstand heat treatment. The packaging must protect against light degradation, moisture changes, microbial contact, oxygen ingress, and other interactions. The material should be structurally strong and capable of withstanding heating temperatures in addition to the normal rough handling during transportation.

Retort bags have the highest barrier properties among flexible packaging. They have near-zero water vapor permeability due to their special lamination structures. Retort packaging can be produced with three-layer or four-layer lamination. Additionally, while they were previously only produced with a metallic appearance, they can now be produced transparently.

Food companies aim to transfer the produced foods to consumers with maximum safety and durability through healthy and durable packaging. In this regard, they aim to prevent the product from being damaged by temperature and pressure factors.
Retort packaging is considered as an alternative to traditional and industrial canning methods.

With retort packaging:

It provides financial gain in logistics, storage and production stages since it takes up less space as a storage area compared to canned products.

It provides convenience in terms of opening and carrying.

It can be produced with a three-layer or four-layer material structure.

Retort can be applied to doypacks, three-side sealed and shaped bag formats.

Thanks to its material structure, it protects the product it comes into contact with against temperature, humidity and pressure effects and extends the product's shelf life.

The flavor and taste of the food are not affected.

It has a long shelf life.

Retort packages are frequently used in food industries such as meat, fish, chicken, cheese, ready-made sauces, cooked ready meals, soups, appetizers, and pet foods.
