Cross Laminated Film For Bitumen Waterproof Membranes
Description:
OUR THREE STEP PROCESS FOR MANUFACTURING HIGH STRENGTH,
DURABILITY, AND QUALITY PLASTIC FILMS IS THE KEY TO SUCCESS.
► 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.
