Polymer Properties Of Polyester Film

     Polyester film is a polymer plastic film, because of its comprehensive performance is more and more favored by the vast number of consumers. Due to the current production and technical level of our country still can not meet the market demand, some still need to rely on imports. Because of the complexity of polyester film and difficult to judge, to the customs supervision brings many difficulties.Polyester Film

     Polyester film is a high-quality fiber-grade polyester chips (viscosity of 0.64) as the main raw materials, the use of advanced technology formulations, through drying, melting, extrusion, casting and stretching made of high-grade film. According to the production of polyester film materials and the production process classification, according to the production of polyester film and the use of raw materials and stretching process can be divided into the following two kinds: two-way Stretch polyester Film (abbreviated BOPET), is the use of light material (also known as a big light material, that is, in raw materials polyester chips added titanium dioxide, after drying, melting, extrusion Casting and vertical and horizontal stretch of high-grade film, the use of a wide range.Polyester Film

    One-way Stretch polyester film (abbreviated as Cpet), is using half extinction material (raw material polyester chips did not add titanium dioxide powder), after drying, melting, extrusion, casting and longitudinal tensile film, in the polyester film grade and the lowest price, mainly for drug tablets packaging. Because the use of less, manufacturers less large-scale production, about 5% of the polyester film field, our enterprises are also less import, standard thickness has 150μm.Polyester Film

    The properties of the polyester film determine its different uses. Different applications of polyester film on the requirements of raw materials and additives, as well as processing technology have different requirements, its thickness and technical indicators are not the same; In addition, only bopet can have a variety of uses, so the film classified according to use is boPET.Polyester Film
