Inheriting JCTimes'spirit of craftsman,with several years of research,experimental analysis and market survey,JCTimes gains a new breakthrough in R&D of blown film die.

It is our ten-year target to fill market gap of high-end blown film die head in China and exploit new internatinal market for Chinese extrusion industry simultaneously.

· Adopt 1.2714 steel,hardness after heat treatment reaches HRC28-34.
· Roughness of flow surface after polishing is 0.015-0.02μm.
· All fasteners are at 12.9 grade.
· Chrome-plating thickness is 0.02-0.04mm,hardness is HV800-950.Or nickel alloy plating, thickness is 0.015-0.02mm,hardness is HV900-1000.
· Maximum bearing pressure 500bar.
· External die lip is designed to be adjustable, to keep the concentricity with internal die lip.

· Optimized design,strong self cleaning capacity,short cleaning time,low pressure loss and easy assembly.

Blown film has great stretchability. As a top grade packaging material,it is with outstanding properties including fresh-keeping, moisture-proof,cold-proof and oil resistance,widely used in packaging for fruit,meat,medicine and so on.
