The 80-micron translucent white or opaque white CPP (Cast Polypropylene) film is a specialized type of release liner that is designed for
use in applications where a thicker, more robust release liner is necessary. The white color is used to differentiate product lines or provide
a clean, neutral background for the product.
Some of the main applications of the 80-micron translucent white or opaque white CPP film include:
1. Labels:
The thicker white-colored release liners are used in labeling applications of products ranging from cosmetics, pharmaceuticals, and
consumer electronics to industrial applications where a more robust adhesive backing is necessary.
2. Tape and adhesive manufacturing:
The thicker white release liner is used as a backing material for tapes and adhesives, especially those used in branding and labeling
applications where a denser and stronger liner is required.
3. Medical and surgical applications:
Medical and surgical products that require a color-coded release film for easy identification can utilize this type of release liner.
4. Dairy and food packaging:
White-colored thicker release liners are used in dairy and food packaging where light-colored products are being packaged, and where
the liner must be strong enough to handle the weight of the product.
5. Personal Care and Hygiene products:
Personal care products such as diapers, sanitary napkins, and incontinence products that require a robust and thicker release liner are
produced using this type of film.
Overall, the 80-micron translucent white or opaque white CPP film provides a more robust and durable release surface for products that require
a thicker, more substantial release liner. The physical properties of the white-colored release liners are generally similar to clear release liners, including tensile strength, chemical resistance, clarity, and dimensional stability, with only a difference in thickness and color. The neutral white color is suitable for a wide range of applications where a clean, unobtrusive background is required, and the thickness of the film makes it ideal
for heavy-duty industrial applications.
CPP (Cast Polypropylene) silicone coated release film has several features that differentiate it from PE (Polyethylene) or BOPP (Biaxially
Oriented Polypropylene) silicone coated release films. Some of these features include:
1. Greater tensile strength:
CPP silicone release films have greater tensile strength compared to PE or BOPP silicone release films.
This makes them more resistant to tearing, puncturing, and other forms of physical damage.
2. High temperature resistance:
CPP silicone release films have excellent high-temperature resistance and can withstand temperatures of up to 120°C.
This makes them suitable for use in applications, such as die-cutting, where high heat is generated.
3. High chemical resistance:
CPP silicone release films are more resistant to chemicals, solvents, and acids than PE or BOPP silicone release films, making them
suitable for use in industrial applications.
4. Excellent dimensional stability:
CPP silicone release films have excellent dimensional stability and maintain their shape and size even after repeated exposure to high
humidity or temperature.
5. Low coefficient of friction:
CPP silicone release films have a low coefficient of friction compared to PE or BOPP silicone release films.
This makes them suitable for use in applications where sliding or slipping is required.
Overall, CPP silicone coated release film provides superior physical properties and performance compared to PE or BOPP silicone coated
release films. Its tensile strength, high-temperature resistance, chemical resistance, dimensional stability, and low coefficient of friction make
it an excellent choice for various industrial applications, including die-cutting, electronics, and automotive industries.
