Cast polypropylene films (CPP)

1. What is CPP film?

CPP films are also manufactured from a combination of various PP polymers. Various constructions of CPP are available (multi-layer option) used to serve a number of applications in specialty packaging, as an adhesive in combination with other plastic substrates for the packaging of food products, using twist wrap in confectionery, etc.

2. Typical specification

Thickness: 12 um, 15 um, 25 um

Size: 400mm – 1400mm

Type: printing, packaging, stamping, composite mold lining, and many other industrial applications

Corona / chemical treatment: 1-sided, 2-sided (both)

3. Features

Excellent thermal glue strength, high resistance to puncture and tear

Excellent packaging integrity at extreme temperatures and high heat resistance

Does not affect the coefficient of friction (COF) control

High yield per unit area and low specific gravity (0.91 g/cm3)

Provides a good moisture barrier

High transparency

The pharmaceutical and healthcare industries use CPP films for long-term drug packaging because CPP films can protect from contamination. Applications in other industries include stand-up pouches, lamination bags, and more.

4. Applications

Food packaging or candy/confectionery packaging

Bread products

Garment packaging

Retort bag

Stationery packaging

Vacuum metallization

Others

5. Quality certificate

– FDA,RoHS,Reach

– 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.
