Sdm Cross Laminated Strength Film

Our SDM Cross Laminated Strength Film is a new generation of High Density Polyethylene Cross Laminated Strength Film, researched and developed by Upass Material Technology (Shanghai) co., Ltd in 2012 independently.
We take HDPE as raw material, and blow to be a cylindrical film with certain thickness by film blowing machine. Secondly, mechanical tensile orientation to finalize the design. Thirdly, the spiral cutting machine cut into sheet film by 45A angle with the original machine direction. Then, coat special glue on the surface of film. Last, cross laminate double-layer in 90A orientation by high-pressure.
Outstanding Features
Excellent dimensional stability, there is no wrinkle and bulb on the waterproofing membranes produced by our SDM strength film after construction, offering your outstanding waterproof performance.
Cross-Lamination provides perfect strength and tears resistance in all directions.
Perfect chemical durability.
Surface of SDM strength film was treated by a special process, bringing you excellent uvioresistant, and long serving life.
Outstanding weather resistance, can be applied in harsh physical environment (-60a --90a ).
Excellent printability.
Puncture and burst resistant, provide excellent nail tear strength and water tightness.
General breakage rate of goods packed by SDM strength film is less than 1% during transport or storage, minimize packaging loss.
