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.

Step 1: Extrusion

► 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.

Step 2: Spiral Cutting

► 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.

Step 3: Cross Lamination

► 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.

Why Cross Laminated?

Puncture Resistance: less accidental damage
Thermal Dimensional Stability: No fish-mouthing or controlled shrinkage
Cold temperature resistant down to -30°C/-20°C
Cross laminated film allows waterproofing membranes to bridge gaps in sheathing
Resistant to damage from incidental movement and settling of the roof
UV Stability for typical job site exposure
