Problems solved by technology

[0004] At the same time, in the production process of the packaging, it is necessary to carry out color printing and other processing on the packaging. After the color printing is completed, the two pieces of packaging are usually aligned to complete the butt joint of the packaging, and then the edge sealing is performed, but there are misalignments in this process. If the situation occurs, usually this part of the packaging bag needs to be discarded, resulting in a lot of waste, and at the same time causing great damage to the environment

Abstract

The invention discloses an environment-friendly food bag and a processing technology thereof. The environment-friendly food bag is formed by co-extruding three layers of films and is divided into an outer layer, a middle layer and an inner layer, the outer layer is a homo-polypropylene layer, the middle layer is a co-polypropylene layer, and the inner layer is a composite layer. By adding modifiedcorn flour into traditional components, the prepared films are good in formability, good in glossiness, moderate in hardness, resistant to acid and alkali, resistant to corrosion and easy to recycleand are a novel green and environment-friendly material. Through the production manner of the processing technology, the production efficiency is effectively improved, various defects of pvc films commonly used in the market are effectively overcome, and a good protection effect is achieved on the environment; and the technology manner is simple and safe, good prospects are achieved, environmentalprotection is good, and the safety of contained foods is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to an environment-friendly food bag and a processing technology thereof. Background technique [0002] In the past ten years, the production and application of plastic flexible packaging films in China have developed rapidly, but they have not paid enough attention to the possible harm to human health of plastic films used in food packaging. example of. In fact, in our country, in addition to plastic wrap, PVC film is also widely used in candy twist packaging and small food twist packaging. The twisted packaging of candies and snacks is PVC twisted film that directly contacts with food. At the same time, its consumer groups are mainly children and teenagers. Therefore, the problem that PVC twisted film may endanger human health should also attract the attention of all aspects of society. [0003] At present, the common memory conjunctiva on the market mainly inc...
