Plastic Bag Manufacturing

Plastic bags are made from plastics (polyethylene, polypropylene, polyester, nylon and others), which are indispensable articles in people’s daily life and are often used to hold other articles. It is made by cutting and sealing plastic blown film under high speed and high temperature, and is welded to seal the border of plastic bags.

According to application’s request, PTFE coated fabric (PTFE sheet), PTFE adhesive tape or PTFE conveyor belt will be used for release. CHANGWEI’s product can withstand high temperature and offer excellent non stick surface, so the plastic bag can be easily released from the welding point.

CHANGWEI is also offering special PTFE zone tape, PTFE tear resistant fabric for these applications.
