Problems solved by technology

However, the extrusion composite process is not suitable for the composite of aluminized film, because the high temperature generated by extrusion composite damages the adhesion of metal aluminum, resulting in a decrease in the composite fastness of the final product.

Abstract

The invention discloses a metalized temperature-resistant anti-stripping film. The metalized temperature-resistant anti-stripping film is composed of a corona layer, a middle layer and a heat seal layer. The corona layer is composed of binary co-polypropylene and methyl methacrylate copolymer. The middle layer is homo-polypropylene. The heat seal layer is composed of ternary co-polypropylene and anti-adhesion master batch. The adhesive force of metal aluminum obtained after aluminum plating is increased by increasing surface polarity of the corona layer, and the aluminum layer attaching forceof the product obtained after aluminum plating is larger than or equal to 2N / 15 mm; and compared with the ordinary aluminum plating film aluminum layer attaching force which is 0.5N / 15 mm, the relatively high temperature can be resisted in an extrusion composite technology, and fastness of the metal aluminum is not influenced.

Description

technical field [0001] The invention relates to a metallized heat-resistant anti-peeling film and a production method thereof. Background technique [0002] Aluminized film is a composite plastic packaging material formed by attaching a layer of extremely thin metal aluminum on the surface of the plastic film by a special process. By attaching metal aluminum to achieve the characteristics of water vapor resistance and oxygen resistance, the CPP-based material water vapor Example of transmittance; transmittance without aluminum plating: 10~25g / m2.24h.40℃, transmittance after aluminum plating: 1.0~1.5g / m2.24h.40℃. Good water vapor resistance and oxygen resistance are widely used in food packaging such as puffed food, biscuits, and tea. The traditional aluminized film is generally suitable for dry lamination, solvent-free lamination, and its low lamination temperature has extremely low damage to the aluminum coating, which can ensure the lamination fastness of the final produc...
