Seven layer co extruded film - asymmetric low-temperature and water boiled film
The basic structure is: PA/TEE/PE/TIE/PA/TEE/PE

Global plastic pollution has surpassed the ecological tipping point, with over 300 million tons of plastic waste entering the oceans every year, posing a threat to human health and the future of the planet. Bamboo, an ancient and modern green resource, is becoming a key to cracking white pollution and promoting sustainable development.

OCA Optical Clear Adhesive is a highly transparent double-sided adhesive film used for optical component bonding, widely used in bubble free lamination processes in display panels, touch screens, and other fields.

Mainly used in biodegradable products such as packaging films, agricultural films, disposable tableware, etc., it conforms to the trend of environmentally friendly substitution of traditional plastics. The production process adopts two stages of esterification reaction and condensation reaction, requiring catalysts (such as tetrabutyl titanate).

The present utility model relates to a polyimide CPI film material winding equipment, which adopts a 3-station turret type and effectively reduces the material tension fluctuation and wrinkling caused by the traditional AB dual station winding time cycle being too long, shortens the turnover and winding interval, improves work efficiency, and reduces material waste. The device is integrated, easy to transport and install, and easy to operate. Featuring ultra-high cost-effectiveness.

PTFE (polytetrafluoroethylene) film is a high-performance polymer material film made from PTFE resin through a special process.
