Environmentally friendly adhesive-free food packaging film

Wuhu City Tianhua Plastic Industry Co., Ltd. is responsible for the “Environmentally Friendly Non-Adhesive Food Packaging Film” undertaken by the Wuhu City Tianhua Plastic Industry Co., Ltd. and has recently passed the technical achievement identification organized by the Provincial Department of Science and Technology.

The successful research of adhesiveless composite membrane technology has fundamentally solved the problem of solvent residue. Its innovative features are: 1) Major technological transformations have been carried out on the basis of advanced equipment, and special static mixers have been used to make the raw materials in the cavity for secondary plasticization, achieving special quality results; 2) In the production process, the mutual pressure between each roller, the tension and the temperature of each heating section of the die are optimized to improve the peel strength of the adhesive-free composite film; 3) The structure of the main part of the silicone roller and its cooling The angle of the steel roll was improved to make the contact time of the film with the base material in the high temperature state fully and improve the composite fastness of the film. The product was inspected by the Anhui Provincial Supervision and Inspection Institute and the Provincial Chemical Product Quality Supervision and Inspection Station. All technical indicators were superior to the national standard GB/T 10005-1998 requirements.
