Film biaxial stretching line, which are represented by poly(ethylene terephthalate) (PET) films, are currently the most widely used polymeric substrate materials in the fields of display technologies, electronic devices, storage media, electronic insulators, automobile, molding, package, printing and architecture. This widespread use is a result of the films possessing high strength, durability, transparency, flexibility and good surface properties.Information and telecommunications equipment have recently required more compactness and portability as well as excellent film properties, such as higher heat resistance and dimensional stability, especially in the field of electronics, environment and energy. It has been difficult for conventional biaxially stretched PET films to meet the future demand, and outstanding films with cost effectiveness are required.

The film biaxial stretching line production line mainly includes a bopet production line, a bopp production line, a bopa production line, a bopla production line, etc., which are extruded and cast through an extruder to form a sheet, and then stretched in both directions in the longitudinal and transverse directions, so called biaxial stretching production line

Sequential stretching is most often used in the production of material such as BOPS, BOPP, BOPET, BOPLA, and BOPTFE. The primary advantage of this method is that it provides a lot of flexibility in process conditions (e.g. MD and TD stretch ratios) and a high production rate. It is also relatively cost effective.

1. BOPET biaxial stretching production line: This production line is used for solar panel, liquid crystal display, heat sealing film, high resistance film, anti-ultraviolet radiation film, solar film, explosion-proof film, food packaging aluminized film and so on.

2, BOPP is used for printing, bag making, adhesive tape and compounding with other substrates, biscuits, sweets, candy, snacks, cigarettes and other packaging.

3. BOPS is used in positive pressure thermoforming machines to make plastic packaging products.

4, BOPA is used for freezing, cooking, vacuum packaging and so on.

5. BOPVA is used for ultra-thin films required for packaging such as cigarettes, printing, and daily necessities.

6, synthetic paper / stone paper: printing, writing, advertising and decoration; for consumables, such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc.; Used in industrial packaging and other fields, such as fertilizer bags, cement bags, rice bags, clothing bags, all kinds of handbags, carton cartons, etc.; stone paper products have strong competitiveness, the market prospects are very promising.
