A waterproof and breathable electromagnetic induction aluminum foil gasket for packaging and its manufacturing process

Abstract

The invention discloses a waterproof and breathable electro-magnetic induction aluminum foil gasket for packaging and a manufacture process thereof. The waterproof and breathable electro-magnetic induction aluminum foil gasket comprises a waterproof and corrosion-proof breathable film patch layer for packaging and an electro-magnetic induction aluminum foil gasket layer which are connected with each other. The electro-magnetic induction aluminum foil gasket layer comprises a linear layer and an electro-magnetic induction aluminum foil layer attached onto the linear layer, and the waterproof and corrosion-proof breathable film patch layer for packaging is connected with the electro-magnetic induction aluminum foil layer in welding mode. Therefore, the waterproof and breathable electro-magnetic induction aluminum foil gasket has the advantages of being short in heating welding time, fast in sealing, good in sealing performance, clean in separation and the like; and enables a container to be tightly sealed, is high in welding strength, has good damp-proof, mould-proof, anti-fake, anti-oxidation and fresh-keeping effects, achieves the purpose of prolonging product shelf life, improves product packaging reliability, and achieves the purposes of leading the electro-magnetic induction aluminum foil gasket to be breathable in the storage and preservation period and adjusting pressure in and out a bottle container to be balanced.

Description

technical field [0001] The invention relates to a gasket and a manufacturing process of the gasket, in particular to a waterproof and air-permeable electromagnetic induction aluminum foil gasket for packaging and a manufacturing process thereof. Background technique [0002] Some chemical liquids (bleach, hydrogen peroxide, peracetic acid, pesticides, herbicides, biological fermentation products, veterinary drugs, cleaning agents, fungicides) or powder self-reactive substances will generate gas by themselves. Previously, the packaging bottle container was completely sealed. The pressure resistance of the bottle is high, and the packaging cost of such self-produced harmless gas substances (except acid and alkali) is very high. In order to solve this problem, some packaging containers used to have an airtight structure of electromagnetic induction aluminum foil gaskets in the past. Packaging, with the accumulation of gas in the container or the rise and fall of temperature, su...

AI Technical Summary

Problems solved by technology

[0002] Some chemical liquids (bleach, hydrogen peroxide, peracetic acid, pesticides, herbicides, biological fermentation products, veterinary drugs, cleaning agents, fungicides) or powder self-reactive substances will generate gas by themselves. Previously, the packaging bottle container was completely sealed. The pressure resistance of the bottle is high, and the packaging cost of such self-produced harmless gas substances (except acid and alkali) is very high. In order to solve this problem, some packaging containers used to have an airtight structure of electromagnetic induction aluminum foil gaskets in the past. Packaging, with the accumulation of gas in the container or the rise and fall of temperature, such containers will burst, collapse, or leak chemicals due to the imbalance of internal and external gas pressure, which will bring safety hazards to safe production and transportation

Inflated or sunken packaging will damage the corporate brand image and affect economic benefits

[0003] The existing technology is not effective in solving the problems of waterproof, dustproof, breathable, and anti-oxidation in packaging containers. The disadvantage is that the airtight performance of the original electromagnetic induction aluminum foil gasket material cannot meet the requirements of chemical liquids.

More importantly, it cannot solve the problem of internal and external pressure balance of self-produced gas in the container and leakage of chemical liquid
