Description

High temperature resistant food package bag

Technical Field

The utility model relates to a high temperature resistance food package bag belongs to food package technical field.

Background

The earliest meat products stored for long term storage at ambient temperature were canned foods, which were iron cans made of tin plate and subsequently over-wrapped with glass bottles. The tin plate and the glass bottle both have high temperature boiling resistance and high barrier property. Therefore, the shelf life of the canned food can reach more than two years, but the tinplate cans and the glass bottles are hard packaging containers, the size is large, the weight is heavy, the chemical corrosion resistance of the tinplate is poor, and particularly when the tinplate cans are filled with acidic food, metal ions are easy to separate out, so that the flavor of the food is influenced. However, since the invention of the eighteenth century, the canned food is popular in the world for nearly two hundred years and till the sixties of the twentieth century, in order to solve the problem of packaging of the last-day food by astronauts, the invention provides an aluminum-plastic composite film which is used for packaging meat food and can be stored at normal temperature for more than one year through high-temperature and high-pressure sterilization. The aluminum-plastic composite film has the similar function as a can, is soft in texture and light in weight, and therefore, the soft can is obtained. At present, meat food with long shelf life stored at normal temperature all over the world is almost completely made of aluminum-plastic composite films if hard packaging containers, tin cans and glass bottles are used, and if soft packaging is used.

If the food cannot be used up once after the packaging bag is torn open, the food cannot be sealed again, and the food is easy to deteriorate. Therefore, the utility model provides a high temperature resistance food package bag solves above problem.
