During The Thermoforming Process Of Thermoforming Film

Thermoforming Film packaging is also called stretch forming packaging. Thermoforming Film refers to the blister, cavity, disc box, etc. formed by the heating and stretching of a thermoplastic plastic sheet, and then the product is fixed on the blister and substrate In order to facilitate the transportation and sales process, it is not easy to be damaged, and the stretch forming film packaging can effectively protect the products with complex shapes and easy to crush. The main test of the whole process for Thermoforming Film is the two steps of thermoforming and heat sealing.

During the thermoforming process of Thermoforming Film, the film should be able to stretch evenly to avoid tiger spots and no holes. Even so, the bottom corner part after stretch forming is the thinnest. In order to meet the barrier properties of Thermoforming Film, the film here (especially the barrier layer) needs to maintain a certain thickness. When thermoforming film is heat-sealed, it is necessary to prevent the contamination of the heat cover during the clothing filling process. If the anti-pollution heat-sealability is not good, the heat-sealing strength may be insufficient, or even leakage may occur.
