Plastic Film Extrusion Machinery Manufacturer-Nanjing Sumino Precision Machinery Co.,Ltd

BOPA film making machine


1. This equipment adopts hot air circulation heating and has the advantages of automatic constant temperature control and low energy consumption.
2. The equipment has automatic setting and automatic winding structure, which is convenient for experiment of different materials.
3. A wide range of processing films can be processed and stretched BOPP, BOPET, BOPA, BOPLA, BOPVA, BOPS, BOPVDC, bidirectional ultra-high molecular weight PE and other thin films, and the longitudinal and transverse stretch ratio of the equipment can be customized according to the product.
4. The transverse stretch magnification can be changed, but the longitudinal direction is unchanged.
5. Simultaneous stretching in both vertical and horizontal directions, making the stretching more uniform, easier to form a film, and the molecular chain arrangement more uniform. Especially in the application of biaxially oriented PA film and biaxially oriented battery separator, biaxial stretching has very obvious advantages.
6. Experiments on barrier performance prove that the synchronous stretching effect is better.


The film biaxial stretching production line is mainly used for stretching pet, pp, pa, pla, cellulose, etc.

1. BOPET biaxial stretching production line: this production line is used for solar panels, liquid crystal displays, heat-sealing films, high-barrier films, anti-ultraviolet radiation films, solar films, explosion-proof films, food packaging aluminized films, etc.
2. BOPP is used for printing, bag making, adhesive tape and composite with other substrates, packaging of biscuits, sweets, candies, flavored snacks, cigarettes, etc.
3. BOPS is used for positive pressure thermoforming machines to make plastic packaging products.
4. BOPA is used for freezing, cooking, vacuum packaging, etc.
5. BOPVA is used for ultra-thin films required for packaging of cigarettes, printing, daily necessities, etc.
6. Synthetic paper/stone paper: printing, writing, decoration, etc.; used for consumables, such as garbage bags, shopping bags, food bags, compact bags, lunch boxes, foot gloves, tablecloths, raincoats, dust covers, etc.; In industrial packaging and other fields, such as fertilizer bags, cement bags, rice noodle bags, clothing bags, various handbags, paper boxes, etc.; stone paper products have extremely strong competitiveness, and the market prospects are very promising.
