Use of high-temperature cooking bags for food packaging

With the development of the food industry, all kinds of packaging compound bags have also been developed with the advancement of science and technology. High-temperature cooking bags are one of them. The high-temperature cooking bag is a composite plastic film bag capable of heat treatment, which has the advantages of both canned containers and boiling water-resistant plastic bags. The food is filled into the packaging and sealed completely, and then subjected to pressurized heat sterilization (cooked food sterilization) processing to form a bag or shaped box packaging. It is suitable for the packaging of meat and soy products. When eating, put the food together with the bag in boiling water to heat it. It can be opened for consumption, even without heating. It is convenient, hygienic and practical, and can keep the original flavor of the food well. Not only is it stored at room temperature for a long shelf life, but also it is convenient for transportation, storage and sales, and manufacturing costs It is also relatively low, very suitable for the consumption needs of modern society, and is a very practical packaging material for modern food packaging machines.

In order to meet the performance requirements of the cooking bag, the cooking bag is mostly composed of three layers of materials. The outer layer of the structure is a high-strength polyester film, the middle layer is aluminum foil with shading and airtightness, and the inner layer is a polyolefin film (such as polypropylene film). ), For heat sealing and food contact. Of course, with the advancement of technology, the introduction of new materials has not only satisfied users’ requirements for the transparency, high barrier properties, heat resistance and high strength of cooking bags, but also directly made various bags to reduce the traditional The compound process in the packaging process makes the product more in line with the hygienic performance requirements, and greatly clears the consumers’ concerns about the residual solvent of food packaging bags. High-temperature cooking bags are generally made of non-degradable and recyclable paper, so the design should use uncoated and plated packaging to prevent food contamination.
