Extrusion Grade

Extrusion is a continuous and economical method for producing products of unlimited length.

Function: Polymer resin is melted, mixed, and compressed by one or two rotating screws inside a barrel. The molten plastic is then forced through a precisely shaped opening, the die.

Key Control: Precise control over temperature and output speed is maintained to preserve product dimensions and prevent distortion during exit and cooling.

Products: HDPE pipes, UPVC profiles, sheets, and thin films (before slitting and winding).

Key
Materials and Applications in Film Casting

The
choice of polymer raw material is crucial for determining the
final film properties and is heavily influenced by the desired application:

1.
Polyethylene (PE) Grades

LLDPE (Linear
Low-Density Polyethylene): Widely used for high-clarity cast film
applications due to its superior toughness and puncture resistance. It is
the core material for high-performance stretch film.
LDPE (Low-Density
Polyethylene): Used for seal layers in laminates where easy heat-sealing and low
cost are prioritized.
HDPE (High-Density
Polyethylene): Less common for thin films but used for stiffer, stronger cast
sheets and liners requiring chemical resistance.

2.
Polypropylene (PP) and Other Polymers

Cast Polypropylene
(CPP): Highly popular
for flexible food packaging, textiles, and medical packaging due to its
high heat resistance and excellent barrier properties.
PET (Polyethylene
Terephthalate): Cast into high-strength, thin films for electrical insulation,
optical displays, and specialty barrier layers.

Critical
Applications

The
high-quality output of the film casting process
supports demanding markets:

Flexible Packaging: Retort pouches, stand-up
pouches, snack food bags (often as a substrate for printing or
lamination).
Hygiene and Medical: Non-woven laminates, breathable
barrier films for surgical drapes and wound care.
Technical Films: Release liners, protective films
for electronic displays, and specialized barrier films for solar panels
(photovoltaics).
