Abstract

The invention relates to a low-migration and high-barrier local positioning anti-counterfeiting laser food packaging board and a production method thereof. The packaging board comprises a base paper layer, and a PE lamination layer, a vacuum aluminized layer, a local positioning anti-counterfeiting laser layer, a laminating coating layer and a plasma corona PET film layer which are sequentially compounded on the upper surface of the base paper layer from bottom to top. Compared with packaging materials in the prior art, the packaging food integrates the holographic laser anti-counterfeiting effect of a local positioning cat eye lens and the dual-protection ultrahigh-barrier property of the PE lamination layer and the plasma corona PET film in order to prevent effective migration of the aluminized layer, achieves the multiple effects of beauty, counterfeiting resistance and ultrahigh barrier, and promotes the development and innovation of the packaging industry.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a low-migration, high-barrier local positioning anti-counterfeiting laser food packaging cardboard and its preparation. Background technique [0002] Packaging migration refers to the residues in food packaging or additives used to improve the processing performance of packaging materials, which diffuse from the inside of the packaging material to the inner surface in contact with food, and then are solvated or dissolved, thus existing in the food. Food packaging is closely related to food safety, and the migration of harmful chemical substances in packaging materials is one of the important ways to cause food contamination. With the improvement of consumers' health awareness, chemical migration in food packaging has attracted increasing attention. [0003] At present, most of the packaging materials in our country are still using aluminum foil composite paper. Alumin...
