1. What is an OPP film?
OPP is a biaxially oriented polypropylene film, which means stretchable, a film made from polypropylene as the main material and biaxially stretched by the flat film method.
2. Typical specification
Thickness: 18 um, 20 um, 30 um
Size: 400mm – 1400mm
Type: printing, packaging, stamping, composite mold lining, and many other industrial applications
Corona / chemical treatment: 1-sided, 2-sided (both)
It has high tensile strength, high hardness, good transparency, and good gloss. Low electrostatic performance, excellent printing performance, and coating adhesion, water vapor resistance, and excellent barrier properties, so it is widely used in various packaging industries.
OPP film can be divided into many types depending on the application, such as ordinary OPP film, OPP thermal laminating film, OPP cigarette packaging film, OPP thin film, porcelain white OPP film, metalized OPP film, and translucent OPP film.
Due to its outstanding advantages, typically being friendly to the environment and people, OPP films are widely applied in life. They appear in almost every field such as:
+ Relatively hard, brittle, good bearing so OPP films are widely used in stationary (pens, rulers, writing pads, …)
+ Odorless, colorless, so they are used to pack fresh foods (vegetables, fresh fruits, …), used to store cakes, jams, or pack herbs with a glue line pressed at the mouth of the bag.
+ Glossy, hard surface so widely used in a garment, fashion, footwear, …
5. Quality certificate
– ISO 9001
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. 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.
