Abstract

The invention discloses a metallizable double-sided corona BOPP extinction heat sealing film and a preparation method thereof. The metallizable double-sided corona BOPP extinction heat sealing film issequentially composed of an upper surface layer, an upper core layer, a lower core layer and a lower surface layer. The corona treatment is conducted on the upper surface layer and the lower surfacelayer, the upper surface layer is a heat sealing layer, the upper core layer is a polypropylene layer, and the lower core layer and the lower surface layer are extinction layers. The heat sealing layer is prepared from the following raw materials in percentage by weight: 96-98% of ternary polymerization heat sealing master batch and 2-4% of anti-blocking master batch. The BOPP film prepared by themethod has high elasticity modulus and low thermal shrinkage rate, and the performance indexes such as haze and glossiness of the extinction layerd are excellent.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a metallizable double-sided corona BOPP matting heat-sealing film and a preparation method thereof. Background technique [0002] Heat-seal aluminized film is a functional film with good transparency, high stiffness, low static electricity, low heat-sealing temperature, haze less than 2%, and small friction coefficient, which is used for metallized substrates. The metallized base material greatly improves the barrier property, thereby prolonging the timeliness of the package, and is widely used in food packaging. After partial printing, it is used for independent packaging of small products, suitable for vertical or horizontal packaging; products are simply printed on the surface and then heat-welded and heat-sealed (lap joint type), packaging CDs, snow cakes, cakes, etc.; products and back-printed BOPP , BOPET film compounded and then self-connected heat-sealed, packaging various...
