SDM strength film is kind of High Density Polyethylene (HDPE) Cross Laminated Strength Film.
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 45°angle with the original machine direction. Then, coat special glue on the surface of film. The last, cross laminate double-layer in 90°orientation by high-pressure.

The SDM means Spiral cut and Double-laminated Machinery drawing.

SDM Strength film offer you excellent tensile strength, tear strength, puncture resistance and weather resistance.
