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. |
