Details of the PET filmBYE a major research and development to production of a functional film coextrusion coating materials and high-end film material, the main products include: protective film, clutch mold, clean sticky dust, PET release film is Bo Yi Xin Cheng from the film a high-end product, the following is the detailed information of the PET filmPET film is the thermal transfer of a material commonly used, the substrate is PET, after coating the silicone oil from the silicone membrane is also called. The conventional thickness from 25um to 150um. There are hot and cold tear and points of light matte, anti-static and anti-scratch treatment, the product has a good adsorption and bonding.PET film is now widely packaging, printing, screen printing, pad printing, nameplates, membrane switches, flexible circuit, insulation products, circuit boards, laser anti-counterfeiting, fit, electronic, sealing material film, reflective material, waterproof materials, medicine (plasters paper), sanitary paper, adhesive, cutting red type processing industries.PET high light membrane: in addition to having excellent physical and mechanical properties of the conventional polyester film, but also has excellent optical properties, such as good transparency, low haze, high gloss. It is mainly used for high-grade aluminum vacuum products, was in the film aluminized mirror, have good packaging decorative effect;, it can also be used for laser anti-counterfeit base film. High light BOPET film market capacity, high value-added economic benefit.PET transfer film: transfer film, also known as thermal transfer film, this transfer film characteristics of high tensile strength, good thermal stability, heat shrinkage, smooth surface, good peel can be used repeatedly. It is mainly used for vacuum aluminum carrier, is placed in a vacuum aluminum machine aluminized PET film, glue and paper composite, and PET film stripping, aluminum molecular layer of adhesive role will be transferred to the cardboard surface, form called aluminized jams.The the the aluminized jam production process is: PET base film transferred to jam off color type layer the layer aluminized layer glue layer.The aluminum vacuum jam a metallic luster jam is developed in recent years, a senior novel packaging materials. This aluminized jam bright color, strong sense of metal, the printed product is beautiful and elegant, can replace the print area bronzing, played the role of the icing on the cake for the beautification of goods. Because it uses aluminum vacuum method, only in the cardboard surface covered 0.25um ~ 0.3um thin and closely shiny aluminum layer, is only Framed aluminum jam one five-hundredth of the aluminum foil layer, so that both noble and beautiful metal texture, biodegradable, recyclable environmental attributes, is a green packaging material.PET reflective film: PET reflective film features the film has excellent optical properties, surface smooth, bright and clean, good thermal stability, shrinkage is small, light aging.Transport facilities with a reflective material lens-type retroreflective film flat top reflective film two kinds, and they are using aluminized PET film to do the reflective layer, on which is coated with a pressure sensitive adhesive after a refractive index of 1.9, certain glass the beads adhesion on PET aluminized and then spray a layer of the butyral surface protective layer Serve. PET reflective film applied to the reflective requirements billboards, reflective traffic signs (reflective road signs, reflective isolation belt, reflective number plate), reflective uniforms, industrial safety signs.Antistatic PET film: The world has entered the information era, the various frequencies, the wavelength of the electromagnetic wave fills the entire Earth space, electromagnetic waves be without shield sensitive electronic components, circuit boards, and communications equipment will produce different degrees of interference data, resulting in distortion of communication disorders. Static electricity generated by the electromagnetic induction and friction on a variety of sensitive components, instrumentation, and some chemical products, as a result of the packaging film electrostatic accumulation of high pressure discharge, the consequences will be devastating, so the development of antistatic PET packaging film is also very important. The antistatic film is characterized by adding certain antistatic agent in the PET film, the film surface to form a thin layer of a conductive layer, and forming a continuous phase and improve the performance of the surface conduction, so that the charge generated as soon as possible leakage. General requirements for the surface of the antistatic film, the specific resistance ≤ 109 ~ 11 ohms.PET Sealing Film: Ordinary PET is a crystalline polymer, the PET film after stretching orientation will produce a greater degree of crystallinity, such as its heat-sealing, then, will produce contraction deformation, so the ordinary PET film does not have the heat-sealing properties. The PET film used merchandise package, in order to solve the problem of the heat sealing, typically using the BOPET film and a PE film or a CPP film composite approach, resulting in a certain extent, limit the application of BOPET film.In order to solve the heat sealing problem, the modified PET resin, and using the die head of the three-layer structure of A / B / C, and has developed a three-layer co-extruded sealing type PET film, this sealing type PET film side sealable layer, it can be directly heat-sealing, and is very convenient to use. The heat sealing PET film can be widely used in the packaging of various commodities and retaining card film field.PET shrink film: polyester shrink film is a new type of heat shrinkable packaging material. Because of its ease of recycling, non-toxic, tasteless, good mechanical properties, in particular, in line with the environmental protection and other characteristics, in developed countries, polyester (PET) has become an ideal alternative to replace polyvinyl chloride (PVC) shrink film.However, ordinary polyester crystalline polymer can only get 30% of the thermal shrinkage of the common PET film through a special process.To obtain a higher heat shrinkage of the polyester film, must also be modified. That is, in order to prepare a polyester film of a high thermal shrinkage rate, the need for ordinary polyester namely poly (ethylene terephthalate) modified by copolymerization. Copolymer modified PET film the highest thermal shrinkage of up to 70% or more. The characteristics of the heat-shrinkable polyester film: it is stable at room temperature (glass transition temperature or higher) shrinkage when heated, and is to occur in one direction more than 70% of the heat-shrinkable. Heat shrinkable polyester film packaging advantages: body-transparent, reflecting the image of goods. His tight packaging, anti-Divergence. Rain, moisture, mildew. No recovery, there are some anti-counterfeiting features. Heat shrinkable polyester film is commonly used in convenience food and beverage market, electronic appliances, metal products, especially shrink label is the most important fields of application. With the rapid development of PET beverage bottles, such as Coke, Sprite, and a variety of juices and other drinks bottles PET shrink film heat seal labels accompanying do they belong to the same polyester, environmentally friendly materials, ease of recyclingutilization. Heat shrinkable polyester film used shrink labels in recent years, also beginning to be used on the packaging of household goods.Because it not only to avoid shock, rain, moisture, rust, and can win a beautifully printed packaging users, at the same time it is a good show a good image of the manufacturer's protective packaging materials. At present,more and more packaging manufacturers instead of the conventional transparent film with printed shrink film. Printed shrink film can improve the appearance of the product grade, is conducive to the advertising of the product, the to trademark brand can produce a deep impression in the minds of consumers.。
