【概要描述】BOPP film is a very important flexible packaging material, which is widely used. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, strength, toughness and good transparency. The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. However, after corona treatment, BOPP film has good printing adaptability and can obtain exquisite appearance effect by color printing, so it is often used as the surface material of composite film.

  BOPP film is a very important flexible packaging material, which is widely used. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, strength, toughness and good transparency. The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. However, after corona treatment, BOPP film has good printing adaptability and can obtain exquisite appearance effect by color printing, so it is often used as the surface material of composite film. BOPP film also has shortcomings, such as easy to accumulate static electricity, no heat sealing, etc. In the high-speed production line, BOPP film is easy to generate static electricity, so it is necessary to install an electrostatic remover. In order to obtain heat sealable BOPP film, heat sealable resin glue liquid, such as PVDC latex and EVA latex, can be coated after corona treatment on the surface of BOPP film, solvent glue can also be coated, and heat sealable BOPP film can also be produced by extrusion coating or coextrusion composite method. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover packaging of cigarettes and books. The induced tear strength of BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no notch can be left on both ends of BOPP film, otherwise BOPP film is easy to tear during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with large amount of BOPP.


  BOPP film can be produced by tube film method or flat film method. The properties of BOPP films obtained by different processing methods are also different. BOPP film produced by flat film method has higher strength and better uniformity of film thickness than that produced by tube film method due to its large tensile ratio (up to 8-10).


  In order to obtain better comprehensive performance, multi-layer composite method is usually used in the process of use. BOPP can be compounded with a variety of different materials to meet the needs of special applications. For example, BOPP can be compounded with LDPE (CPP), PE, Pt, Po, PVA, etc. to obtain high gas resistance, moisture resistance, transparency, high and low temperature resistance, cooking resistance and oil resistance. Different composite films can be applied to the packaging of oily food, rare food, dry food, impregnated food, all kinds of cooked food, monosodium glutamate, pancake, New Year cake, etc.
