Detailed Product Description: | Ordinary polyester is generally from terephthalic acid (PTA) and ethylene glycol (EG) esterification, condensation reaction in the system, are crystalline polymers (strictly speaking, the crystalline and amorphous regions coexist polymer) . The so-called modified copolymer is in addition to terephthalic acid (PTA) and ethylene glycol (EG) outside the two main components, and then a third and even fourth component involved in the introduction of transparent PET copolymer film is intended to enable it to generate asymmetric The molecular structure of PET form amorphous copolymers. Introduction of a third or even a fourth monomer may be a dibasic acid or diol. Wherein the alkylene black translucent PET film, the dicarboxylic acid isophthalic acid, malonic acid, succinic acid, adipic acid, sebacic acid and the like; diol neopentyl glycol, propylene glycol, diethylene glycol alcohol, 1,4-cyclohexane dimethanol. Such as with a dicarboxylic acid (Acidic) conduct copolymerization, the obtained copolymer PET, known as APET; when the terms of the diol (Glycolic) copolymerized modified PET copolymers are prepared, is called PETG. The introduction of the third monomer described above, the most commonly used dicarboxylic acid is isophthalic acid (IPA) IPA was added to change the structure of the polyester closely symmetrical destruction macromolecular chain regularity, thereby reducing inter-macromolecule force, the polyester molecular structure becomes more supple. Meanwhile, due to the introduction of IPA, difficult nucleation crystallization of the polyester, and with the increase of the amount of the introduction of IPA, APET copolymer of partially crystalline transition black PET film to non-crystalline polymer, since such a modified polyester APET decreased ability to crystallize the amorphous region becomes large, it can be used to manufacture a high shrinkage film. Recommended IPA is preferably added in an amount of about 20%. High pressure low density polyethylene, low molecular weight polyethylene contained, easily soluble in fat, so long as utensils made of polyethylene containing edible oil, which can be low molecular weight polyethylene dissolution, leaving the fat and more food with rancid flavor. Thus, consumers in the traditional packaging of edible oil consumption, but also "consume" the inedible harmful to health of low molecular weight polyethylene. Therefore, the old cooking oil fortified with vitamin A in a package has undoubtedly been eliminated embarrassment. In Europe and other developed countries, PE packaging film has already been eliminated, but in the form of clear regulations restrict the use of PE, replaced by a safer, more effective and transparent packaging materials PET film. Consumers are increasingly focused on the quality of life and health consciousness gradually increase today, the old packaging of edible oil will have to gradually withdraw from the consumer market. PET film packaging to replace PE is to strengthen the irreversible trend of edible oil. Mist transparent PET film film _ _ provided by Cosmos Electronics Electronic Materials Co., Dongguan City, Manhattan.
