40 μm red color cast polypropylene silicone coated release film for food, medical can industrial packaging
The 40-micron translucent red or opaque red cast polypropylene silicone coated release film is a specialized type of release liner that is
used in specific applications where a colored release liner is required. The red color has a primary function for product differentiation
as products with color distinctions stand out better than products with a standard white or clear release film.
Some of the main applications of the 40-micron translucent red or opaque red cast polypropylene silicone-coated release film include:
1. Automotive and Aerospace:
The red release liner is used in the production of automotive and aerospace parts and components that require color-coded release films
for easy identification.
2. Labels:
The red color can be used to differentiate product lines, product families, and specific ingredients in the labeling of consumer items,
food service products, personal care products and pharmaceutical pill packs.
3. Graphic Arts:
The red release liner can be used as a backer material for graphic arts, such as vinyl graphics and decals.
4. Signage:
The red release liner is used in the production of colored signs and banners.
Overall, the 40-micron translucent red or opaque red cast polypropylene silicone coated release film is used to provide a reliable and consistent
release surface in products where easily recognizable color-coded release liner is needed. The physical properties, such as chemical resistance,
barrier properties, and strength, for colored and clear release liner ranges can be the same, with the difference being only in color.
The main feature of Cast Polypropylene (CPP) silicone coated release film compared to Polyethylene (PE) silicone coated release film is its
higher transparency and clarity. CPP films are known to have better optical properties than PE films, which makes them a preferred choice for
applications that require high clarity and visibility.
In addition to its optical properties, CPP silicone coated release films also offer better moisture resistance, chemical resistance, and dimensional
stability compared to PE silicone coated release films. CPP films have a higher melting point, which makes them more resistant to high
temperatures and suitable for use in various applications such as food packaging and pouches.
PE silicone coated release films, on the other hand, are softer and more flexible than CPP films, which makes them an ideal choice for
applications that require conformability and ease of use. PE films also have excellent elasticity and low-temperature properties, which makes them
suitable for use in cold storage and transport conditions.
In summary, the main feature of CPP silicone coated release film compared to PE silicone coated release film is its higher optical properties, moisture resistance, chemical resistance, and dimensional stability. On the other hand, PE silicone coated release films offer better flexibility, elasticity, and low-temperature performance. The choice between the two types of films will depend on the specific application requirements and performance criteria.
