Processing technology of aluminum-plastic packaging bag

Abstract

The invention relates to the technical field of aluminum-plastic food packaging bags, in particular to a processing technology of an aluminum-plastic packaging bag, which comprises the following steps: taking a poached PE film as a base layer, taking a VMPET aluminum-plated film as a coating layer, and compounding a transition layer made of a thermally induced shape memory polymer film between the coating layer and the base layer through an aluminum-plated film compound adhesive; a tearing opening of an existing aluminum-plastic food packaging bag is easy to fold and break; therefore, through the arrangement of the curled edge, the curled edge can perform curled protection on the tearing opening of the aluminum-plastic food packaging bag, the situation that the tearing opening of the aluminum-plastic food packaging bag is folded and broken before use is avoided, food deterioration caused by damage of the aluminum-plastic food packaging bag is prevented, and the safety of food quality is improved; meanwhile, no sharp corner is generated at the edge of the product, and the problem that the palm is stabbed due to improper use is avoided, so that the use safety of the device is improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic food packaging bags, in particular to a processing technology of aluminum-plastic packaging bags. Background technique [0002] The aluminum-plastic bag is a packaging product that combines various packaging advantages, with low cost and exquisite printing; the product has: anti-static, anti-ultraviolet, moisture-proof, oxygen-proof and light-shielding, cold-resistant, oil-resistant and high-temperature resistant, fresh-keeping, oxygen-proof and easy-sealing Strong and other characteristics, used in industrial packaging, daily chemical packaging, food packaging, medicine, hygiene, electronics, aerospace, science and technology, military industry and other fields, according to the material structure can be divided into: pure aluminum composite bags, aluminized composite bags two, Among them, the aluminized composite bag is an aluminum-plastic food packaging bag commonly used in food packag...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when aluminum-plastic food packaging bags are used for retort and packaged food, often due to the lack of softness of the aluminum-plastic food packaging bags, when the tear opening of the aluminum-plastic food packaging bags is too large, the tear strength of the tear opening position is low, so The tear of the aluminum-plastic food packaging bag is easy to fold and break, and the tear of the aluminum-plastic food packaging bag is too small, which is easy to cause the problem of inconvenient tearing
