50 μm Opaque white cast polypropylene silicone coated release film for label,

Product Specification

Cast polypropylene (CPP) silicone coated release film is widely used as a release liner for pressure-sensitive adhesive products

and also as a protective layer for sensitive surfaces. It has several advantages, including high clarity, stiffness, and tear resistance

that makes it a preferred choice for many applications.

Some of the application scenarios in which CPP silicone coated release film is largely used are:

1. Label production:

    CPP silicone coated release film is commonly used as the release liner for the production of pressure-sensitive labels or

    stickers that require easy removal from their backing material. Its high clarity and excellent flatness make it suitable for

    high-quality label printing.

2. Tape production:

    CPP silicone coated release film is used as the release liner for pressure-sensitive adhesive tapes such as

    masking tape, duct tape, and specialty tapes. Its high-strength, dimensional stability, and printing capabilities make it ideal

    for such applications.

    Here are some products made with CPP coated silicone release film:

    1) Pressure-sensitive labels and stickers:

        The liner of pressure-sensitive labels and stickers is often made of CPP coated silicone release film

        due to its superior clarity and ultimate smoothness, allowing high-quality printing.

    2) Adhesive tapes:

        CPP coated silicone release film is used as the release liner for many types of adhesive tapes, including duct tape,

        masking tape, and other specialty tapes.

    3) Transfer tape:

        CPP coated silicone release film is used as transfer tape in graphic arts and screen printing applications, providing

        a strong hold and a clean transfer of graphics or text onto the surface.

    4) Automotive industry:

        CPP coated silicone release film is used as a protective layer for the surface of car parts during transportation,

        painting, and other industrial processes requiring protection against scratches and damage.

    5) Electronics industry:

        CPP coated silicone release film acts as a protective layer for sensitive devices of electronics products while they

        are assembled and transported, providing a barrier against dust, moisture, and other contaminants.

    6) Medical industry:

        CPP coated silicone release film is used in medical devices packaging as it provides a barrier against chemicals and

        sterilization methods and allows easy release.

    7) Construction industry:

        CPP coated silicone release film is used as a vapor barrier, roofing membrane, and waterproofing material.

3. Screen printing:

    CPP silicone coated release film is used as a transfer tape in graphic arts and screen printing applications.

    It provides a strong hold and a clean transfer of graphics or text onto the desired surface.

4. Automotive industry:

    CPP silicone coated release film is used as a protective layer for the surface of car parts during transportation, painting,

    and other industrial processes that require protection from scratches and damage.

5. Electronics industry:

    CPP silicone coated release film is used as a protective layer for sensitive electronic devices, during assembly and

    transportation, providing a barrier against dust, moisture, and other contaminants.

*  Overall, CPP silicone coated release film is preferred for applications that require high-strength, dimensional stability,

    and great printing capabilities. It is widely used in various industries, providing protection, and aiding in the manufacturing

    of high-quality products. 

    Cast polypropylene (CPP) silicone coated release film is designed to be disposed of after use,

    but it still requires high performance in mechanical properties due to its primary function as a release liner or protective layer.

    Firstly, the mechanical properties of the film affect its processing ability during the production of pressure-sensitive adhesive products.

    The CPP silicone coated release film should have the appropriate mechanical properties to ensure that it can be handled efficiently

    during manufacturing and converted into the desired form, e.g., labels or tapes. The film's stiffness, tensile strength, and elongation

    properties play a crucial role in its converting processability.

    Secondly, the mechanical properties of the film are essential for the protection of the underlying product or surface when used as a

    protective layer. The CPP silicone coated release film needs to be stiff and robust enough to resist punctures, tears, or abrasions that

    may occur during handling, transportation, or storage. A release liner with poor mechanical properties may result in damage to the

    underlying surface, requiring costly replacements or repairs.

    Lastly, the high-performance mechanical properties of the CPP silicone coated release film also improve its functionality in its primary

    role as a release liner. The film should provide a consistent and clean release without leaving behind any adhesive residue,

    meaning it should be dimensionally stable, flat, and smooth.

    Therefore, even though CPP silicone coated release film is disposable, it is still necessary to have high-performance mechanical properties

    to ensure that it fulfills its primary roles of protecting surfaces, aiding in manufacturing, and providing clean release.
