High Density Polyethylene Cross Laminated Film for Waterproof Membranes
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.
