Silicone Coated Polypropylene Release Film, Monoaxially Oriented Polypropylene, used for packaging film,cigarette film.
Characteristics | MOPP is the abbreviation of Monoaxially Oriented Polypropylene. The uniaxially oriented polypropylene (MOPP) film has a significant high tensile strength in the mechanical direction, and its longitudinal strength and longitudinal crack resistance are greatly improved, and it has good kink. It has the advantages of light weight, transparency, non-toxicity, moisture resistance and high mechanical strength. It is widely used in packaging films, cigarette film pulling wires, etc., and is widely used as composite film. substrate. Widely used in self-adhesive tapes, cable tapes, tear tapes, silicone-coated base films, strapping tapes (such as wrapping steel), article labels, tire lining applications, etc. At present, the most commonly used production method of MOPP film in the industry is the main casting method (flat film method). In the casting method, the prepared plastic is firstly plasticized and melted by a co-extruder. It is extruded through a T-shaped structure forming die and cast in a sheet shape onto the roller surface of a smoothly rotating cooling roller. The film is cooled and shaped on the cooling roller, and then the product is rolled up after being pulled and trimmed. The products produced by the casting method (flat film method) have superior performance and mature equipment.It has high production efficiency and is suitable for mass production, and is currently widely used by enterprises. |
