Product Description
In 1958, Italy Montecati company invented BOPP film, and in 1962 to achieve industrialization, the application of the world immediately, is now developing in the direction of high performance, multi-function. The promotion of different products with high added value and special functional film will become the development trend of plastic film industry. BOPP film has the characteristics of light weight, non-toxic, odorless, moisture-proof, high mechanical strength and size stability.
BOPP Film industry definition and classification
BOPP film, full name bidirectional tensile polypropylene film. BOPP film has the advantages of light weight, non-toxic, odorless, moisture-proof, good mechanical properties and dimensional stability, excellent transparency, excellent printing performance after surface treatment and so on. It is widely used in the packaging of food, candy, cigarette, juice, milk and so on. At the same time, BOPP film can also be combined with polypropylene flow film (CPP film), polyethylene film (PE film) and polyvinyl alcohol film (PVA film), etc., to improve the performance of gas resistance, moisture resistance, oil resistance and tear resistance.
Main types of BOPP:
Light film thick film and thin film, under normal circumstances, thick film refers to more than 25 μthickness, film refers to less than 19 μthickness
It is achieved by absorbing and scattering light, which can generally improve printing and packaging
(light film) extinction film (matte film often no heat sealing layer, so the use of more and other films (such as CPP, table grade, but the price is relatively high, and domestic manufacturers are less, elimination box food, high-grade packaging
BOPBT) and other composite use for 3 layers of co-extruded stretch film, the surface will generally have a thermal sealing layer. Different from BOPP film, pearlescent film cost; And the common pearlescent film shows white, opaque pearlescent effect, the difference is that the density of pearlescent film is mostly controlled below 0.68, which is conducive to saving food packaging bags, printing labels, has a certain light blocking ability, and has a protective effect on products that need to avoid light
The cover film is generally a thin light film under the Angle of 18 μ. After a single or double corona, aluminized laser substrate tape substrate, high precision printing
Aluminized film. Cheap, beautiful, excellent performance, practical strong gaseous aluminum atoms precipitate to the surface of plastic film and form bright metal color packaging medicine, cosmetics, biscuits and other dry, puffed food packaging
Laser film can be molded with molded functional layer, transparent BOPP film, do not need another pre-coated molded layer, that is, high-end commodity anti-counterfeit packaging, decorative packaging
Capacitive film is a kind of excellent dielectric material of plastic film capacitor made of isotactic polypropylene resin by biaxial directional stretching
