China developed a blow molding method breathable film production line

Breathable membrane has the special function of breathable and impervious, and it has a wide range of uses. It can be applied to hygienic products, thermal insulation and breathable clothing, fresh-keeping packaging of agricultural and sideline products, seawater desalination, sewage treatment, wastewater regeneration, pure water production, protective clothing for medical care, and pharmaceuticals. Industrial filter sterilization and so on.

In the past, the breathable film production line mainly relied on imports. At present, China's Guangdong Jinming Plastic Equipment Co., Ltd. has developed a blown film breathable film production line. The main features of its production process are the addition of calcium carbonate to raw materials. The breathability of the film is achieved by using the principle that calcium carbonate particles form micropores during stretching. The important component stretching system of this production line stretches the formed film product twice, and the stretching ratio can realize accurate stepless adjustment. The production packaging machine 'target=_blank> transparent film specification width is 1600mm, thickness 0.035~0.045mm.
