1 What is BOPA film?
Two directional polyamide films (BOPA) are made from polyamide resin (PA) and have outstanding properties, which can be used for high-demand packaging.
PA films are widely applied in the field of laminated packaging to produce packaging applications in industrial packaging, daily chemical packaging, food packaging, warming packaging, vacuum packaging, electronic packaging, pharmaceutical packaging, Li-ion battery packaging.
BOPA membrane has good elongation resistance, penetration resistance and high flexibility, shock resistance, anti-osmosis, and good air, high transparency, shininess, easy printing. , withstand high temperatures. BOPA membranes are particularly suitable for use in the preservation and packaging of perishable food products, frozen food, ready-to-eat food, vegetables, agricultural products, packaging products. pharmaceutical, electricity, electronics …
2 Typical specification
Thickness: 12 um, 15 um, 25 um
Size: 400mm – 1400mm
Corona treatment: 1 side (Inside) or 2 sides (Both Sides)

BOPA film has very good tensile strength, puncture resistance and flexibility, good impact resistance, permeability, and air resistance, high transparency, shininess, easy printing, temperature resistance high. BOPA film is especially suitable for use in the preservation and packaging of food products requiring vacuum, perishables, frozen food, instant food, vegetables, agricultural products, pharmaceuticals, electricity, electricity death…
PA film is widely used in the field of complex packaging to produce packaging applications in industrial packaging, daily chemical packaging, food packaging, reheating packaging, vacuum packaging, electronic packaging, pharmaceutical packaging, Li-ion battery packaging.

6 Production process
BOPA film is produced by laminating technology with modern machinery manufactured in Germany. BOPA film is produced through the following stages: extruder -> casting -> water bath -> Stretching -> pull roll -> winder -> slitter and package.
BOPA is mainly a three-layer ABC sandwich structure, in which the inner and outer layers of A and C are functional additives added to pure nylon, the proportion is 10%, and the proportion of pure nylon particles in layer B is 80%.
Functional additives mainly increase the surface of the film to have anti-block, good printing, and increased fluidity.
7 Film Stretching
This is the stage that makes a difference in the quality of the BOPA film. The stretched film will not stretch during printing and laminating, will not cause distortion during printing and lamination, and will not cause the bag to warp due to the difference in surface tension between the two surfaces of the film. 100% BOPA film of Hop Nhat packaging ensures that it will not stretch during printing and splicing, the surface tension between the two sides of the film will be the same.
LISIM is a magnetic-type mechanism that uses a magnetic linear motor to drive the film clip. The size of the magnetic pulse generated by the magnetic motor controls the film clip to extend in the MD direction. The angle of the film clip travels the track to adjust the TD direction. The entire extension is carried out in a large oven.
For the purpose of protecting the product in the most optimal way, BOPA film will be packaged as follows:
1/ BOPA film will be covered with a layer of aluminum film to prevent moisture and dirt
2 / 2 ends of the roll will have 2 pieces of cardboard attached to the 2 cores
3 / 2 square wooden covers will be fastened to the film roll to ensure that the 2 ends of the roll do not touch the ground and bear the force of deformation.
4/ The sturdy 5-layer carton is used as the outermost layer to protect the products inside from impact, dirt, and other hazards.
8 Nylon film quality direction
With the aim of creating the best products for consumers. We have invested a lot of modern equipment to test the mechanical and physical properties of the BOPA film, ensuring that the output quality of the product is always within the controlled standard.
