The following three-dimensional bag manufacturers will introduce the characteristics of food cooking bags for youThe retort bag is a composite film bag that can be heat-treated, and it has the advantages of both a can container and a boiling water-resistant retort bag.After more than ten years of use, it is an ideal sales packaging container.The retort pouch is mostly made of three layers of materials. The typical structure of the retort pouch is: the outer layer is polyester film for reinforcement; the middle layer is aluminum foil for light, moisture and air leakage; the inner layer is polyolefin Film (such as polypropylene film) for heat sealing and food contact.In terms of food packaging, compared with metal can containers and frozen food packaging bags, retort bags have many unique advantages:
①Maintain the color, fragrance, taste and shape of food. The retort pouch is thinner, which can meet the sterilization requirements in a short period of time, and preserve the original color, aroma, taste and shape of the food as much as possible.
②Easy to use. Retort bag can be convenient, safeFully open. When eating, put the food into the boiling water together with the bag to heat5minReady to open and serve, even without heating.
③Convenient storage and transportation. The retort bag is light in weight, can be stacked and stored, and occupies a small space. After packaging food, it occupies a smaller space than a metal can, which can make full use of the storage and transportation space and save storage and transportation costs.
④ Save energy. Because the retort bag is thinner, the temperature in the bag can quickly reach the lethal temperature of bacteria when heated, and the energy consumption is less than that of iron cans30~40%.
⑤Easy to sell. Retort pouches can be packed separately or combined with different foods according to market needs, and customers can choose them at will. In addition, due to the exquisite decoration, the sales volume has also been greatly increased.
⑥ long storage time. The food packaged in retort bags does not need to be refrigerated or frozen, and has a stable shelf life, which is comparable to metal cans. It is easy to sell and easy to use at home.
⑦The manufacturing cost is low. The price of composite film for manufacturing retort bags is lower than that of metal plates, and its production process and required equipment are much simpler, so the price of retort bags is lower. Equipment packaging bag manufacturers tell you that retort bags also have their shortcomings, mainly due to the lack of high-speed filling Equipment has a certain impact on mass production.
