Product Description
70μm Opaque White MOPP Release Film
High-performance 70 micron opaque white monoaxially oriented polypropylene silicone coated release film designed for food packaging, lamination, tapes, labels, and industrial applications.
Primary Applications
This specialized release film is primarily used in the production of pressure-sensitive adhesive (PSA) tapes, serving as a high-quality release liner across multiple industries.
Key Application Areas
- Medical & Healthcare: Ideal for wound dressings, medical devices, and diagnostic kits due to superior release properties
- Labeling: Used in automotive, food & beverage, pharmaceutical, and personal care product labels
- Graphics & Signage: Excellent for vinyl decals and graphic wraps with premium release characteristics
- Electronics: Suitable for circuit board protection, thermal management, and gasketing tapes
- Building & Construction: Applied in sealing tapes, waterproofing tapes, and masking tapes
The silicone coating ensures easy removal and application of pressure-sensitive adhesives without residue or surface damage. The opaque white color provides excellent opacity and contrast for clear visibility of graphics and text.
Material Comparison: MOPP vs CPP
Silicone coated monoaxially oriented polypropylene (MOPP) and cast polypropylene (CPP) films serve different application needs based on their physical properties:
Key Differences
- Tensile Strength: MOPP offers higher strength for robust applications
- Puncture Resistance: MOPP provides superior resistance for tapes and labels
- Printing Quality: MOPP's smoother surface supports high-quality graphics
- Clarity: CPP offers better optical clarity for transparent applications
- Temperature Resistance: MOPP maintains stability in high-temperature environments
MOPP is ideal for applications requiring strength, puncture resistance, and thermal stability, while CPP excels in optical clarity applications like flexible packaging.
