PETG (polyethylene terephthalate-1, 4-cyclohexanedimethanol terephthalate) is a novel copolyester formed by copolymerizing terephthalic acid (PTA) or dimethyl terephthalate (DMT), Ethylene Glycol (EG) and 1, 4-Cyclohexanedimethanol (CHDM). Compared with the traditional PET, the dihydric alcohol EG in the synthesis process of the novel copolyester PETG is partially replaced by CHDM, and the copolyester PETG is used when the CHDM content is less than 50 percent of the total content of the dihydric alcohol. Because of the extremely low crystallinity of PETG even no crystallization, the transparency of PETG is extremely high, the toughness of PETG is also extremely excellent, and the elongation at break of American Istman industrialization PETG products can reach about 300 percent, which is far higher than that of PET. PETG also has good chemical resistance and has the performance of resisting diluted acid and alkali corrosion. Meanwhile, PETG resists gamma ray irradiation, does not change color after gamma ray irradiation, and still can keep higher transparency and stability. The PETG film also has higher barrier property to gas (oxygen and carbon dioxide), and is suitable for packaging products with higher requirements on gas barrier property. The PETG is mainly used for preparing a high-shrinkage film in the aspect of films, the shrinkage rate of common PET is about 30%, and the shrinkage rate of the PETG film can reach 70%, so that the PETG film has the advantages of high plastic uptake, high transparency, high gloss, low haze, easiness in printing, difficulty in falling and low natural shrinkage rate during storage. The bi-directional stretching PETG film is suitable for high-grade packaging, printing, electronic and electric appliances, cable wrapping, insulating materials and high-quality base materials in various industrial fields. The unidirectional stretching PET heat shrinkable film is suitable for various external labels such as cans, polyester bottles, various containers and the like.
The multilayer co-extruded composite film is a novel composite film structure, can make up for the performance defects of a single-layer plastic film, exerts the advantages of each layer of material, achieves the purpose of making up for the deficiencies of each layer of material, has better comprehensive performance and some outstanding packaging characteristics, and is one of the most ideal film materials meeting the special requirements of packaging contents at present. However, the coextrusion of PET and PETG to produce films is currently not well studied.
