Detailed Product Description: | With the continuous development of packaging technology and improve the quality of black PET film packaging, packaged goods packaging film performance requirements have become increasingly prominent, the emergence of a number of materials with special properties, such as having a light shielding effect and high surface quality plating good aluminum film, abrasion resistance, dimensional stability, scratch alkylene black light transmissive film PET film, multi-material having high barrier properties of composite films. Continuous application of new materials, and promote the rapid development of the flexible packaging market. Growth in market demand and the development of specific applications, packaging film material cut to the increasingly high demand for cutting equipment requirements are more demanding. On the other hand, with the gradual promotion of automated packaging equipment in the packaging industry, such as food packaging, cigarette packaging, these automatic packaging machines for quality material after cutting requirements are very picky, which gives the high-grade cutting machine precision control brings a broad space for development. Previously used by domestic enterprises with high precision, high speed slitting few manufacturers mainly for foreign monopoly. On the development of domestic cutting machine, there is a profile in the industry analogy: Early Slitter simple structure, the speed at 100m / min or so transparent PET film, mechanical friction and winding way to manual control, people metaphor Later, after some renovation, rewinding, etc. with the clutch control, traction control and a single motor winding, the speed at 200m / min following the film, called "simulated machine";; for "telephone" Since the new high-speed automatic points cutting machine, using digital automatic control, the speed at 300m / min or more, as in the field of modern communications "digital machine." With the technological capabilities of domestic enterprises promotion, technology and reliability is also rising. The application of digital technology is becoming a typical feature of high-speed automatic cutting machine development. 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 the terephthalic acid (PTA) and ethylene glycol (EG) two main components, and then introduce a third or even fourth component involved in the copolymerization, the purpose is to make it generate an asymmetric molecular structure to form amorphous PET copolymer. Introduction of a third or even a fourth monomer may be a dibasic acid or diol. Wherein the dicarboxylic acid isophthalic acid, malonic acid, succinic acid, adipic acid, sebacic acid and the like; diol neopentyl glycol, propylene glycol, diethylene glycol, 1,4 ring hexane 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 transition from crystalline to non-crystalline polymer portion, due to the ability of such modified polyester APET crystallization drop, 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 transparent PET film | film | Cosmos Electronics provided by Electronic Material Co., Dongguan City, Manhattan.
