The 40-micron translucent white cast polypropylene silicone coated release film is a type of release liner that is mainly used in the production
of pressure-sensitive adhesive tapes, labels, and other types of coated products. The film has a thickness of 40 microns, which makes it relatively
thin and flexible, with good mechanical properties.
Some of the most common applications of the 40-micron translucent white cast polypropylene silicone-coated release film include:
1. Pressure-Sensitive Tapes:
The film is used as a backing material in the production of various pressure-sensitive tapes such as packaging tapes, masking tapes, and
other types of adhesive tapes.
2. Labels:
The release liner is used as a backing material for labels used in a wide range of applications, including food and beverage, pharmaceutical,
and personal care products.
3. Specialty Coated Products:
The film is used as a release liner for specialty products that require a reliable and consistent release mechanism such as protective films,
transfer tapes, and laminates.
4. Graphics and Signage:
The film is used as a backer material for self-adhesive signs and graphics.
Overall, the 40-micron translucent white cast polypropylene silicone coated release film provides a reliable and consistent release surface for
adhesive products. The film's translucency provides visual appeal and makes it ideal for use in various labeling applications where the underlying
surface needs to show through.
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.
