Synthetic Roofing Underlayments Application Cross Laminated Film
Description:
It is made of HDPE Film as the carrier which through multi-layer co-extrusion blow molding
into embryos, and then by multiple pull Stretching, then rotary cutting into a film substrate
at vertical distribution of 45 °, finally through cross-compositing by lamination machine.
Due to its cross-stacking structure is different from ordinary single-layer or multi-layer film,
it has the thermal stability, dimensional stability, two-way tear resistance, two-way uniform
tension and high elongation which are not available in traditional films. Make it the ideal
surface film for underlayment and waterproofing membranes.
