Description:
It is a high-strength multi-layer composite film,It is made of HDPE as the base material,
adding plasticizer, plasticizer, stabilizer, antioxidant, UV absorber, toughener and other
additives through multi-layer co-extrusion blow molding into embryos, and then by multiple
pull Stretching, then rotary cutting into a film substrate with a horizontal and vertical
distribution of 45 °, and finally through cross-laminated.
OUR THREE STEP PROCESS FOR MANUFACTURING HIGH STRENGTH, DURABILITY,
AND QUALITY CROSS LAMINATED FILM.
High density polyethylene resin (HDPE) is extruded via the blown film process to form a tube.
The tube is cooled and collapsed into a flat tube.
After the tube is flattened, it is fed into a multi stage orienter. During orientation, the film is
stretched in the machine direction aligning the polyethylene molecules. The resulting film is
very strong in the machine direction.
The oriented tube is then annealed and wound up. The annealing step removes stress in the
film and controls shrinkage. The annealed film retains its high MD strength.
The next step of the process is spiral cutting. In this step, the flattened, oriented tube in unrolled,
rotated and re-inflated to form a round tube.
As the film is fed forward and rotated, it is cut on a bias (around 45 degrees) and wound up.
The spiral cut film's orientation is at 45 degrees to the machine direction.
Finished spiral cut rolls are mounted on corresponding spindles.
Films are fed through and laminated with an extruder with their orientation directions crossed
at 90 degrees. The films are laminated together with a layer of polyethylene.
After lamination, film is surface treated for ink adhesion and graphic purposes.
Finally, the film is wound on a core to estimated yardage.
Application:
A cross laminated film that is taken to new levels of performance. After countless iterations in
our lab, we created a film that features outstanding strength, a heightened spectrum of
resistances in many categories, and much more. In fact, you have probably already used a tag,
label, or package made with award winning Cross Laminated Film, as it can be found in electrical
cord labels, pilfer-resistant flexible packaging, pool chemical packaging, and construction
waterproofing membranes.
