Manufacturing process for food packaging container

Abstract

The invention discloses a manufacturing process for a food packaging container. The manufacturing process includes the following steps that A, hot melting is performed, crop straw particles are added into hot injection molding equipment, and the crop straw particles and plastics form a soluble mixed material together; B, hot injection molding is conducted, and the soluble mixed material obtained in the step A is injected into a food packaging container mold; C, demolding and cooling are carried out, and after cooling, a food packaging container base which has already been formed in the food packaging container mold of the step B is taken out; and D, heat sealing is performed, the food packaging container base obtained in the step C is subjected to heat sealing with an aluminum foil composite membrane, and accordingly the food packaging container can be manufactured. The manufacturing process for the food packaging container has the beneficial effects that crop straw is effectively used as a manufacturing raw material of the food packaging container, and therefore natural resources can be better integrated, and benign development of the ecological environment is guaranteed; and meanwhile, the crop straw is used for making the food packaging container, so that production cost is reduced, degradation of the food packaging container can be facilitated, and the environment is protected.

Description

[0001] 【Technical field】 [0002] The invention relates to a manufacturing process of food, medicine, solid and liquid packaging articles, in particular to a manufacturing process of food packaging containers. [0003] 【Background technique】 [0004] At present, in the field of packaging, plastic bags or plastic boxes are usually used for food packaging. However, this packaging method relies on its good sealing performance, but ignores that it cannot be recycled, and most of it becomes disposable consumer goods. In this current environment Bringing heavy pressure, the excessive use of plastic products has become a major factor of environmental pollution. At the same time, food packaging containers that do not have reusable uses have also caused a lot of waste of resources. As a large agricultural country in my country, crop straw It is usually burned as a very cheap combustible material.

[0004] At present, in the field of packaging, plastic bags or plastic boxes are usually used for food packaging. However, this packaging method relies on its good sealing performance, but ignores that it cannot be recycled, and most of it becomes disposable consumer goods. In this current environment Bringing heavy pressure, the excessive use of plastic products has become a major factor of environmental pollution. At the same time, food packaging containers that do not have reusable uses have also caused a lot of waste of resources. As a large agricultural country in my country, crop straw Usually burned as very cheap combustibles, because the calorific value of crop straw is not high, this method is not conducive to the integration and utilization of resources, and is not conducive to the healthy development of the ecological environment
