70 μm opaque white MOPP release film, for food packaging, lamination, tapes

Product Specification

The main application scenario for 70 micron opaque white monoaxially oriented polypropylene silicone coated release film is in the production

of pressure-sensitive adhesive (PSA) tapes. This film is commonly used as a release liner in the manufacture of PSA tapes for various applications.

Some of the specific applications of this film in PSA tapes include:

1. Medical and Healthcare:

    The opaque white film's high-quality release properties make it ideal for use in medical and healthcare applications such as wound dressings,

    medical devices, and diagnostic kits.

2. Labeling:

    The film is used in the production of labels for various end-use applications, including automotive, food and beverage, pharmaceuticals, and

    personal care products.

3. Graphics and Signage:

    The opaque white film is used in the production of graphics and signage tapes, including vinyl decals and graphic wraps, due to its excellent

    release properties.

4. Electronics:

    This film is used in the production of tapes for electronic applications such as circuit board protection, thermal management, and gasketing.

5. Building and Construction:

    The film is used in the production of construction tapes such as sealing tapes, waterproofing tapes, and masking tapes, among others.

The silicone coating on the release liner helps to ensure that the pressure-sensitive adhesive can be easily removed and applied without leaving

any residue or damaging the surface. The opaque white color provides excellent opacity and contrast to ensure the PSA tapes' graphics and text are easily visible. In general, 70 micron opaque white monoaxially oriented polypropylene silicone coated release film is an excellent choice for

industries where the tape's visual appearance is important, or where a high-quality release liner is required.

Silicone coated monoaxially oriented polypropylene (MOPP) film and cast polypropylene (CPP) film are both commonly used in various

applications. However, there are significant differences in their physical properties, and these differences significantly impact their application

scenarios. Here are some of the significant differences in the application scenarios between these two types of films:

1. Tensile Strength:

    MOPP has a higher tensile strength than CPP, which makes it ideal for applications where high strength and robustness are required.

    Conversely, CPP's lower tensile strength makes it more suitable for applications where strength is not the primary consideration.

2. Puncture Resistance:

    MOPP has excellent puncture resistance, which makes it more appropriate for applications where there may be the potential for physical

    damage, like tapes and labels. CPP, on the other hand, may not be suitable for these applications due to its lower puncture resistance.

3. Printing Quality:

    MOPP has a smoother surface than CPP, making it more ideal for printing high-quality graphics or fine details.

    CPP mainly displays better print quality compared to other films.

4. Clarity:

    CPP offers excellent optical clarity, making it more suitable for applications that require transparency, such as food packaging. MOPP,

    on the other hand, may be less appropriate in these situations as it provides slightly hazy clarity.

5. Temperature Resistance:

    MOPP offers better thermal stability, making it suitable for high-temperature applications. CPP, on the other hand, may not perform well

    under high-temperature conditions.

Overall, the choice between silicone coated MOPP film and cast polypropylene (CPP) film depends on the application's specific requirements.

MOPP is a great choice for applications that require high strength, puncture resistance, and high-temperature operations. CPP's superior optical

clarity and relatively lower costs make it more suitable for applications such as flexible packaging, shrink film packaging, and label applications.
