Embodiment Construction

[0007] A low-friction CPP aluminized film consisting of an aluminum layer, a corona layer, an intermediate layer and a heat-sealing layer. The heat-sealing layer is added with 3% SP-6 produced by Beijing Tianxing Ruihe Chemical Technology Co., Ltd. Polypropylene smooth masterbatch. During the aluminizing process, in order to prevent the slippery agent in the heat-sealing layer from seeping out due to heat, the cooling temperature of the aluminizing machine was lowered from -5 degrees to below -15 degrees. Every time a roll of product is produced, clean the rollers of the equipment with a clean rag dipped in alcohol to prevent the aluminum slag on the aluminum roller from scratching the CPP film and increasing the friction coefficient.

[0008] The CPP aluminized film produced according to the above process does not differ from the ordinary CPP aluminized film in appearance, but the friction coefficient is less than 0.3, which is significantly lower than 0.6 of the ordinary alu...

Abstract

The invention discloses a CPP (casting polypropylene) aluminizing film with low friction coefficient. 3% of SP-6 slipping agent master batch is added into a heat-seal layer. In an aluminizing process, for the purpose of preventing a slipping agent in the heat-seal layer from seeping due to heating, the refrigerating temperature of an aluminizing machine is lowered from subzero 5 DEG C to subzero 15 DEG C. The friction coefficient of the CPP aluminizing film is decreased greatly, so that slip can be generated at a sealing part very easily when a package is opened, and the package is easy to open.

Description

technical field [0001] The invention relates to a CPP (casting polypropylene) aluminized film and a production process thereof, especially a low friction coefficient CPP aluminized film and a production process thereof. Background technique [0002] At present, for the packaging bags made of ordinary CPP aluminized film, due to the high friction coefficient of the film, the relative slip between the film and the film is not easy to occur at the seal, and the packaging bag is not easy to open, especially for children. Contents of the invention [0003] The purpose of the present invention is to provide a CPP aluminized film with a low coefficient of friction, which can make the front and back of the curled film easy to slip, so that consumers can easily open the packaging bag. [0004] The technical solution of the present invention to solve the above problems is: a low friction coefficient CPP aluminized film, which is composed of an aluminum layer, a corona layer, an inte...
