Material Selection and Design

It is necessary to determine which substrates to use, how to combine them, and which ink and adhesive to use according to the purpose of the retort pouch. The so-called end use refers to what kind of food the bag is to be packaged and what is the weight of the package. After packaging, how high temperature should be withstood, so that the packaging has a reasonable cost performance.

In order to meet the requirements of the performance of the retort pouch, the outer layer of the structure chooses high-strength polyester film, and the middle layer chooses light-shielding and air for dense aluminum foil, polypropylene film is used for the inner layer. Three-layer structure has two types: PET/AL/CPP and PET/PA/CPP, and four-layer structure has PET/AL/PA/CPP.

Food grade materials

Commonly used food-grade packaging materials are aluminum foil, nylon, polyester, polyethylene terephthalate, etc. In order to increase the performance of food packaging bags, several materials are generally used for compounding.

Features

1、 PE is suitable for low temperature use, RCPP is suitable for high temperature cooking
2、 PA is to increase physical strength and puncture resistance
3、 AL aluminum foil is to increase the barrier performance and shading
4、 PET increases mechanical strength and excellent stiffness


High barrier properties

Food-grade packaging materials must have high barrier properties. Grease food requires high oxygen and oil resistance; dry food requires high moisture resistance to ensure the safety of packaged food. Aromatic food requires high aroma retention; fresh fruit and vegetable food requires packaging with high oxygen, carbon dioxide and water vapor permeability.

High tensile strength

In addition, food packaging materials must have high tensile strength, tear resistance, impact resistance, excellent chemical ability, and no chemical reaction with the food inside to ensure food safety; in addition, it must have high temperature resistance. Performance, meeting the requirements of high temperature disinfection and low temperature storage of food.
