Embodiment Construction

[0007] In the present invention, the heat-sealing layer process formula of the casting polypropylene CPP masterbatch is replaced by the 7641 product of the common Singapore polyolefin private company into 3980 propylene-based low-temperature elastomers produced by the U.S. Aikeson Company, And 50% of the low-density polyethylene produced by Japan's Primeman company with the brand name SP2040. During the aluminum plating production process, the process refrigeration temperature is lowered from -5 degrees to below -20 degrees, and the operating speed is reduced from 600 meters per minute to less than 400 meters.

[0008] The ultra-low temperature CPP aluminum-coated film produced by this process formula can be sealed normally at only 85 degrees Celsius, and the heat-sealing strength reaches 8N, with less breakage rate and fast sealing speed.

Abstract

The invention discloses an extra-low / ultra-low temperature heat-sealing CPP (Casting Poly Propylene) aluminum laminated film and a production process thereof. The CPP film consists of an aluminum layer, a corona layer, an intermediate layer and a heat-sealing layer; and a master batch of the heat-sealing layer is prepared from 50% of propenyl low-temperature elastomer and 50% of polyethylene. In an aluminum plating production process, the process temperature is below -20 DEG C, and the operation speed is below 400m / min. The CPP aluminum laminated film provided by the invention can be normally sealed at the temperature of 85 DEG C.

Description

technical field [0001] The invention relates to a CPP (casting polypropylene) aluminized film and a production process thereof, in particular to a CPP aluminized film with a relatively low heat sealing temperature and a production process thereof. Background technique [0002] Ordinary CPP aluminized film needs about 120 degrees Celsius to seal normally when sealing, the sealing speed is slow, and the bag breaking rate is relatively high. In response to this defect, the existing technology has been improved, and a low-temperature (about 105 degrees Celsius) heat-sealed or ultra-low temperature (about 95 degrees Celsius) heat-sealed CPP aluminized film and its production process have been invented. Contents of the invention [0003] The purpose of the present invention is to provide an ultra-low temperature CPP aluminized film that can be normally sealed only at 85 degrees Celsius and has a heat-sealing strength of 8N. [0004] The technical solution of the present inventi...
