The easy-to-tear PET film is a classification in PET film. The main feature is that it has the characteristics of easy tearing on the basis of the characteristics of ordinary PET film, and is convenient to use.
PET film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for secondary processing such as printing and paper bags. . The PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no proper antistatic method. Therefore, attention should be paid when packaging powdery articles.
The new composite type easy-to-tear PET film: through technological innovation and improvement, the product is specially treated to change the molecular structure of the film to form a composite film. The overall smooth and non-notched sealing degree is not easy to be damaged by external force and mis-tear, which causes the package to be damaged. Through repeated test experiments to determine the best value of the easy tear process, the composite film printing product can be easily torn open from any direction and position. The product adopts a corona coating surface, which makes the printing easier to attach, does not fall off, and the font and color senses are more comfortable, which lays a foundation for mass production and packaging of various products.
