Product Description
80μm Yellow Cast Polypropylene Film Heat Resistance
80 μm yellow cast polypropylene film for food, medical, and industrial packaging applications.
80-micron translucent yellow or opaque yellow cast polypropylene (CPP) film is a thicker and stronger packaging material than both 50-micron and 60-micron CPP films. This robust material offers exceptional performance for demanding packaging requirements.
Primary Applications
- Heavy-Duty Packaging: Withstands weight and pressure of construction equipment and machinery parts
- Frozen Food Packaging: High moisture and gas barrier properties protect frozen fruits, vegetables, and meats
- Medical and Pharmaceutical Packaging: Protects sensitive products from environmental factors including moisture and contaminants
- Industrial Packaging: Secures automotive parts, metal hardware, and heavy-duty items during transportation
- Gift and Handicraft Packaging: Attractive yellow color and high clarity enhance visual appeal
- Stationery Packaging: Protects pens, pencils, and markers during handling and shipping
Key Features
Cast polypropylene film features excellent transparency, high gloss, and superior moisture barriers, making it ideal for applications requiring product visibility. The material is highly durable, flexible, and offers excellent sealing properties for heat sealing applications. CPP film demonstrates exceptional resistance to punctures, tearing, and abrasion, ensuring reliable performance during rough handling. Additional benefits include good stiffness, dimensional stability, excellent printability, and clear graphics reproduction for effective branding.
Manufacturing Process
- Polymerization: Propylene monomers polymerized under pressure and high temperature
- Extrusion: Polypropylene resin pellets melted and extruded through a flat die
- Orientation: Sheet stretched across machine and transverse directions to enhance mechanical properties
- Cooling: Film cooled using cooling rolls and stored on take-up rolls
- Finishing: Surface treatments applied to improve printing quality and adhesion
Advantages Over BOPP Film
- Improved sealing properties with higher seal strength
- Enhanced clarity and gloss for superior product visibility
- Better hot tack properties for high-speed packaging operations
- Increased heat resistance for hot-fill and retort applications
- Higher puncture resistance for enhanced durability
