ADVANTAGESIt is an inevitable trend for PET twist film to replace PVC twist film. Its product performance has unparalleled superiority.
①Environmental protection: PET twist film is made of polyester, which is an environmentally friendly and recyclable product that is not destructive to humans and the environment; and the release of methane when PVC products burn is a substance that can cause cancer in humans. PVC products in Europe and America are If food contact is strictly prohibited, some of the most stringent Western European countries even prohibit PVC film from being used in the packaging of children's products;
②Economic and efficient: PVC products must be above 28μ to have sufficient hardness and stiffness to meet the requirements of aluminum plating and printing, so as to show the stiffness of the product. PET products have sufficient strength and stiffness, so they can produce 19μ, 23μ, 25μ different thickness products. Among them, 19μ is mainly used for manual packaging of dried meat, fresh fruit packaging or paper-plastic composite kink packaging. The 23μ and 25μ are mainly used for candy and chocolate twisted packaging;
③ Stable performance and high efficiency: The maximum speed of PVC machine bag is 1000 pieces / minute, while PET can reach 2000 pieces / minute. Because PVC materials are relatively brittle and have poor flatness, the film width is generally controlled at about 60CM, while the limited printing film width of PET products can reach more than one meter, and the printing speed of PET products can reach more than 200M / minute, while PVC cannot More than 150M / minute. Therefore, PET products are obviously more advantageous in terms of printing efficiency;
④ Beautiful and high-grade: The aluminum layer of the PET twist film is more firm. If the protective resin (gold oil) is added properly during the printing process, the printed pattern will be bright and clear; at the same time, the PET has high rigidity and corrosion resistance to perform local aluminum washing Or press the information layer to process the laser effect, the printing effect is strong three-dimensional, greatly improving the grade of the packaged product;
