The breathable film allows air to circulate while keeping out moisture. More than 5 years of experience in researching and manufacturing the breathable film extrusion line allows us to gain advanced extrusion technologies. From the raw material plastification and casting to the final stretch forming, each process presents a challenge to HANDERNs expertise. 

In comparison to other Chinese film extrusion lines, our extrusion equipment exhibits many unique advantages in configuration optimization, energy saving, and manufacturing and processing technologies. Overall performance tests show that each and every technical specification of our extrusion machine reaches internationally advanced level. As a matter of fact, HANDERN plastics extrusion line is among the fastest, most advanced Chinese equipment for producing breathable films.
