PET film is a polar film with a surface tension of 45-50 dyn without treatment. It is also a film with good firmness no matter what type of plastic ink is printed on. However, after the two-component polyurethane glue is applied to dry composite with other films, especially after PE film is composited, sometimes the printing ink layer is glued from the PET film and delamination occurs (composite thicker PE Deinking of the film is even worse). That is, the printing ink layer on the PET film, after being compounded, is partially or completely transferred to the inner film. So, what is the reason for this? Is there any way to avoid it? Since PET film has excellent barrier properties and strong anti-leakage properties, it is difficult for the solvent to penetrate, and the solvent absorption of the ink is relatively poor. The binder (resin) of the plastic surface printing ink has a good affinity with the PET film, so printing on the PET film is stronger than the printing ink in the plastic composite. In fact, the ink layer transfer of the printed PET film after compounding has nothing to do with the use of surface printing ink. Instead, the use of composite back printing ink is more prone to ink transfer. Pay attention to PET film printing and dry lamination: 1. Use as little ink as possible, and the ink should be dry (dry) to prevent false drying of the ink (especially when printing with chlorinated polypropylene composite plastic ink) . If the printing speed of the printer cannot be turned on, and the effect of the drying box is poor, you can rewind the printed matter once, and blow air or leave it for some time during rewinding, and then recombine after the ink hardens. Good to rewind and blow air, beware of printing film adhesion). 2. The amount of glue applied during the compounding must be small, and the solvent of the compound glue must be evaporated as much as possible when passing through the drying tunnel (check whether the exhaust system of the drying tunnel is unblocked, and the compound hot drum temperature of the compound machine should not be lower than 70 ℃.

What are the uses and characteristics of fluorine release film and non-silicon release film? Source: Protective film factory direct sales Release time: 2019-11-26 Hits: 3010 1. Fluorine release film is also called fluorine plastic release film. This kind of release film is made of fluorinated organic silicon coated on the surface, and has the characteristics of high temperature resistance. For silicone tape, it has excellent peeling performance. Fluorine release film is mainly used in high temperature tape and gold finger compound die cutting process. 2. In addition to the heavier peeling force of non-silicon release film, it also does not use silicon series release agent, so it can also perform its function in some areas that cannot contain silicon. The non-silicon release film produced by Dingli Film Technology has the characteristics of uniform and stable release force, uniform thickness, strong temperature and weather resistance, good tensile strength, and good thermal stability. The main uses of non-silicon release film are hot melt adhesive, HC transfer, micro-adhesive and micro-adhesive protective film processing. In addition, because of its heavy peeling force, it can effectively prevent the release film from moving or falling off when processing very small parts. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with multiple functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing Film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, optical PET film, etc. Interested parties welcome to inquire!

1. The most important feature of semi-reinforced film is its high longitudinal tensile strength, and it is not easy to break under high tension. It is mainly used for packaging seals for boxed items. Commonly used standard thicknesses are 20μm, 28μm, 30μm, 36μm, 50μm. 2. Bronzing film. The biggest feature is good tensile strength and transparency, stable thermal performance, and low separation force from certain resins. It is mainly suitable for small size changes during high temperature processing or as a transfer carrier. The conventional standard thickness is 9μm, 12μm, 15μm, 19μm, 25μm, 36μm. 3. Printing composite packaging film. The main characteristics are good transparency, good penetration resistance, superior chemical resistance, temperature resistance and moisture resistance. It is suitable for the packaging of frozen food and food, medicine, industrial products and cosmetics. Commonly used standard thicknesses are 12μm, 15μm, 23μm, 36μm. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide range of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, warm and thoughtful service, and the spirit of assisting partners to achieve their own careers.
