As one of the professional petg film manufacturers in China with abundant experience in this area, today we would like to introduce some basic information about petg film form the point of view of the petg film manufacturers as below.
First of all, PETG is a kind of amorphous copolyester. With the increase of CHDM in the copolymer, the melting point decreased, the glass transition temperature increased, the crystallinity decreased, and finally the amorphous polymer was formed. In general, the content of CHDM in PETG is 30% ≤40%. It has good viscosity, transparency, color, chemical resistance, and stress whitening resistance. It can be hot-formed or extruded blow molding quickly. Its viscosity is better than that of acrylic acid. Its products are highly transparent, excellent impact resistance, especially suitable for molding thick-wall transparent products. Its processing performance is excellent, can carry on the arbitrary shape design according to the designer’s intention. You can make it by traditional extrusion, injection molding, blow molding and suction molding. It can be widely used in sheet material, high performance shrinkage film, bottle and profile and other markets. So, a lot of petg film manufacturers join to this area.
Second of all, the transparent material with thick 1~25.4mm can be prepared by conventional molding method. It has outstanding toughness and high impact strength, and its impact strength is 3 to 10 times higher than that of modified polyacrylic esters. It is widely used in indoor and outdoor signs, storage shelves, vending machine panels, furniture, construction and mechanical baffle, etc. For example, PCTG card is mainly used in Europe, but it has been more and more used in North America and Asia. The reason is that it has a wide range of processing. It has high mechanical strength and excellent flexibility, so compared with PVC, it has high transparency, good luster, easy printing and environmental advantages. PETG materials can be used in credit cards. For countries that require card materials to be more environmentally friendly, PETG can replace PVC. PETG meets all the requirements of the International Standard of Credit Card (150/IEC7810). So, from this point of view, PETG film can be widely used and become more and more popular amongst the petg film manufacturers.
The last but not the least, specially used in high performance shrinkage film, with a shrinkage of more than 70%, petg film can be made into the packaging of complex shape container. The finished product has the advantages of high plastic absorption, high transparency, high gloss, low haze and so on. It also has the advantages of easy printing, not easy to fall off, and low natural shrinkage when stored. Therefore, petg film is widely used in shrinkage labels of beverage bottles, food, packaging and electronic products. PETG film is suitable for high-grade packaging, printing, electronic and electrical appliances, cable bandaging, insulation materials and high quality substrate in various industrial fields. Uniaxial tensile PET, thermal shrinkage film is suitable for all kinds of cans, polyester bottles, containers and other external labels. Compared with PVC shrinkage film, PETG shrinkage film also has the advantages of environmental protection.
