BOPP film tape introduction --

BOPP film is a very important flexible packaging material and is widely used. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. BOPP film has low surface energy and needs corona treatment before coating or printing. However, after corona treatment, the BOPP film has good printing adaptability, can be printed in color, and has a beautiful appearance effect, and thus is often used as a surface layer material of the composite film. BOPP films are also insufficient, such as easy accumulation of static electricity, no heat sealability, and the like. In high-speed production lines, BOPP film is prone to static electricity, and an electrostatic remover is required. In order to obtain a heat-sealable BOPP film, a heat-sealable resin glue such as PVDC latex, EVA latex, etc. may be applied after corona treatment on the surface of the BOPP film, or a solvent glue may be applied, or extrusion coating or The method of coextrusion compounding produces a heat sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover of cigarettes and books. The initiating tear strength of the BOPP film is improved after stretching, but the secondary tearing strength is very low. Therefore, no cuts can be left on both end faces of the BOPP film, otherwise the BOPP film is easily torn off during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with a large amount of BOPP.

The BOPP film can be produced by a tubular film method or a flat film method. The performance of BOPP films obtained by different processing methods is also different. The BOPP film produced by the flat film method has a higher draw ratio (up to 8-10), so the strength is higher than that of the tube film method, and the uniformity of the film thickness is also good. In order to obtain better comprehensive performance, it is usually produced by a multi-layer composite method during use. BOPP can be combined with a variety of different materials to meet specific application needs. For example, BOPP can be combined with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture resistance, transparency, high temperature, low temperature, retort resistance and oil resistance. Different composite membranes can be applied to oily foods and precious tastes. Food, dry food, impregnated food, various cooked foods, monosodium glutamate, pancakes, rice cakes, etc.

BOPP
a. Chinese name: biaxially oriented polypropylene film. b. colorless, extremely high transparency.
c. Because it is biaxially stretched during the manufacturing process, its tensile strength and impact strength are excellent; therefore, the material is the most commonly used printing material in the packaging industry, and because the material has no heat sealing performance (can not be sealed) ), so can not be used as a composite heat sealing material.
d. Cold resistance, heat resistance are very good, adapt to temperature: -40 ~ 120 degrees Celsius, melting point 165 degrees Celsius.
e. Isolated water vapor performance is excellent, but the oxygen barrier is poor.

f. Common thickness: 20um, 30um, 40um.
g. Most of the product packaging that does not require high barrier properties can choose this material as the printing material.
Like the surface of the outer bag of snack food (snacks) in the supermarket (usually 2~3 layers), most of them use this material, and those beautiful print patterns are printed on this layer of material... There are still unknowns to send an email: easttapemachine668@163.com QQ: 2332962802
