Problems solved by technology

However, due to the temperature resistance limitation of the selected coating for ordinary temperature-resistant transfer aluminized paper, when the OPP film is heat-sealed, the heat of the heat-sealed part will pass through the coating composed of the release layer and the bonding layer, making the coating The molecular configuration of the resin changes, resulting in rheology and destruction, which in turn causes air and heat to penetrate into the resin layer, resulting in deterioration of light reflectivity and discoloration, which greatly affects the appearance of cigarette packs and other product packaging

Abstract

The present invention relates to a temperature-resistant type transfer aluminized paper and its production process. Said process successively includes the following steps: coating release layer on the film; coating anchoring layer on release layer; vacuum aluminizing on the anchoring layer; coating adhesive on the aluminized layer; then making them be combined with paper; stripping film from release layer so as to obtain the invented temperature-resistant type transfer aluminized paper.

Description

technical field [0001] The invention relates to a composite material, more specifically, the invention relates to an aluminized paper-based composite material and a production process thereof. Background technique [0002] The aluminum-paper composite material produced by the vacuum aluminum-plating transfer method has a strong metallic texture although it uses less aluminum; it has strong light-shielding, temperature-insulating, and moisture-proof properties, and can replace pure aluminum foil, aluminized film and other composite products. And it is suitable for subsequent processing with printing machines, embossing machines, high-speed cross-cutting machines and other machines. Therefore, in recent years, it has been used as a new type of environmentally friendly packaging material in the packaging industry at home and abroad, such as being widely used in cigarettes, food, medicine and other packaging. field. [0003] Existing vacuum aluminized transfer method produces a...
