Working Principle of Biaxially Oriented Film Production Line
The biaxial stretching process improves film performance by stretching polymer materials in two directions:
● Machine Direction (MD)
● Transverse Direction (TD)
This process aligns molecular chains, significantly improving:
✔ Mechanical strength
✔ Transparency & gloss
✔ Barrier properties (O₂ / CO₂ / moisture)
✔ Heat resistance
✔ Dimensional stability
After stretching, the film is heat-set and cooled to lock in molecular orientation.
Why Choose Our Biaxial Stretching Film Line?
✔ High output capacity: up to 1500 kg/h
✔ High speed operation: up to 280 m/min
✔ Excellent film thickness uniformity
✔ Advanced MD & TD stretching control system
✔ Energy-saving extrusion system
✔ Suitable for multilayer functional films
✔ Stable long-term industrial operation
Through the longitudinal stretcher and transverse stretcher, the film is subjected to external forces and stretched sequentially in both the longitudinal and transverse directions by a certain factor. This process aligns the molecular chains or crystalline planes in the direction parallel to the film plane, leading to ordered orientation. The film is then heat-set in the stretched state, fixing the oriented macromolecular structure. After cooling and subsequent treatments, the film is produced.
Due to the molecular orientation during stretching, this type of film exhibits excellent physical stability, mechanical strength, gas barrier properties, higher transparency and gloss, as well as toughness and wear resistance.
Plastic films suitable for biaxial stretching production mainly include polyester, polypropylene, polyamide, polystyrene, and polyimide films.
What are the applications of a biaxially oriented plastic film production line?
The biaxially oriented film production line is primarily used for stretching materials like PET, PP, PA, PLA, cellulose, and others.
BOPET Biaxial Stretching Production Line: This production line is used for solar panel films, LCD display films, heat sealable films, high-barrier films, UV radiation-resistant films, solar films, explosion-proof films, and food packaging metallized films.
BOPP: Used for printing, bag making, adhesive tapes, and lamination with other substrates. It is commonly used for packaging cookies, sweets, candies, snacks, cigarettes, etc.
BOPS: Used for pressure forming machines to produce plastic packaging products.
BOPA: Used for frozen food, steaming, and vacuum packaging applications.
BOPVA: Used for ultra-thin films needed for cigarette packaging, printing, and everyday consumer goods packaging.
Synthetic Paper/Rock Paper: Used for printing, writing, and advertising decoration.
It is applied in consumable goods such as garbage bags, shopping bags, food bags, zip-lock bags, meal boxes, shoe covers, gloves, tablecloths, raincoats, dust covers, etc. It is also used in industrial packaging such as fertilizer bags, cement bags, rice and flour bags, clothing bags, various tote bags, and paper boxes. Stone paper products are highly competitive, and the market outlook is very promising.
The biaxial stretching film production line is primarily used to produce general-purpose packaging films such as BOPP, BOPS, BOPET, and BOPA, as well as specialized films including PE biaxially stretched battery separators, PVDF biaxially stretched solar cell separators, and biaxially stretched microporous breathable membranes. As large-scale complete equipment in plastic processing machinery, biaxial stretching film production lines exhibit excellent mechanical properties, including high rigidity, fold resistance, and effective gas barrier properties (against oxygen, carbon dioxide, and water vapor).
Composition of Biaxially Oriented Film Production Line Equipment:
The manufacturing technology of the biaxial stretching production line includes the design of various components such as feeding, extruder, melt line (including filtration and metering), die, casting, longitudinal stretching, transverse stretching, thickness measurement, traction, and winding.
