From polymer resins,
the materials are being melted in the extrusion die to produce high
quality films for various type of application. The end-products
are the following:
1. CPP Films (cast
propylene) – good transparency, scratch
resistance, moisture and water proof, heat resistance but inferior
in gas barrier property. CPP is a good replacement for LDPE/LLDPE
because of its glossy appearance and low haze properties but it
has higher sealing temperature than polyethylene materials. The
following are the kinds of CPP film being produced in our east line:
A. CPP Laminating
grade (2-sides heat sealable/1-side
corona treated; from 20micron to 200micron thickness)
– transparent, white or any color variants, CPP lamination films
are commonly used as replacement for BOPP and LDPE film materials.
Used as lamination substrates for noodles, biscuit, soap/detergent
and other laminated packaging materials. B. CPP print/bag grade
(2-sides heat sealable/1-side corona treated; from 20microns to
200micron thickness)
– transparent, white or any color variants, it is used for single-film
packing for sugar, bakery bags, soap/detergent wrappers and other
packing materials. C. CPP metallizable grade/CPP metallized
film
(2-sides heat seallable/1-side corona treated; from 20micron to
80micron thickness)
– metallized film is a replacement for aluminum foil film. Although
metallized film is inferior in quality ang properties compared to
aluminum foil as barrier film for laminated products, it has almost
the same characteristics of foil and cheaper in price. Used as lamination
substrates for chips snack, confectionary products and other packaging
materials.
