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 film tape introduction --

BOPP sealing tape is made of biaxially oriented polypropylene film (BOPP) and coated with acrylic pressure sensitive adhesive. Because of its excellent characteristics of strong tensile strength, light weight and low cost, it is widely used in various packaging, bonding, fixing and other applications. Especially in the sealing of carton, and with automatic packaging machine, has become the mainstream of packaging materials. At present, the conventional colors have been transparent, beige, milky white and the like. At the same time, it is also a fine packaging, according to customer requirements to produce a variety of colors, text, pattern of printing tape and multi-color tape. Select the tape to clarify two purposes:
First, the characteristics of the tape: (stickiness, temperature resistance, retention, presence or absence of residual glue, material quality star, with or without curling, masking effect, tensile strength, length, stiffness, color, weather resistance, solvent resistance , smoothness, dimensional accuracy, tin infiltration <Generally not>, cohesive force)
