Surface Film Application PE Laminated Film For Waterproof Membranes
Description:
It is a multi-layer composite film,made of HDPE as the base material,
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 with an extruder with their
orientation directions crossed at 90 degrees.

Advantages:
| 1. Puncture Resistance: less accidental damage |
| 2. Thermal Dimensional Stability: No fish-mouthing or controlled shrinkage |
| 3. Cold temperature resistant down to -30°C/-20°C |
| 4. Cross laminated film allows waterproofing membranes to bridge gaps in sheathing and is resistant to damage from incidental movement and settling of the roof |
| 5. UV Stability for typical job site exposure |
