0.09mmx1250mm Root Penetration Resistance High Density Polyethylene Cross Laminated Film
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-compositing. 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.
The performance of this product is stable without deformation.
It possesses high tensile strength, elongation and superior resistance to termperature, tearing, puncure, UV and root penetration.
It has excellent water rightness(nail shank), self-healing properties as well.
With integrating a good appearance, cost saving and environmental protection, the products are largely used for bitumen based waterproofing membrane,
explosive packaging, heavy metal packaging, vairous labels, adhesive tapes, high end printing, etc.
For waterproof membranes
