Product Description
50μm Opaque Cast Polypropylene Film
50 μm opaque white cast polypropylene film designed for food, medical, and industrial packaging applications.
Product Overview
Cast polypropylene (CPP) film is manufactured through a casting process and serves diverse flexible packaging needs across multiple industries.
Primary Applications
- Food Packaging: Ideal for snacks, bakery goods, meat, cheese, and other food products with excellent clarity and gloss for enhanced product appeal
- Medical Packaging: Suitable for medical devices and products, offering high heat-seal strength, moisture barrier, and puncture resistance
- Industrial Packaging: Used for textiles, stationery items, and various industrial products
Key Features & Benefits
- Excellent transparency and high gloss for superior product visibility
- Outstanding moisture barrier properties
- High durability with flexibility and excellent sealing properties
- Superior resistance to punctures, tearing, and abrasion
- Good stiffness and dimensional stability for consistent performance
- Excellent printability with great graphic clarity for branding
Manufacturing Process
- Polymerization: Propylene monomers are polymerized under pressure and high temperature to produce polypropylene resin pellets
- Extrusion: Resin pellets are melted and extruded through a flat die to form a continuous sheet
- Orientation: Sheet is stretched across machine and transverse directions to enhance mechanical properties and clarity
- Cooling: Film is cooled using a cooling roll and stored on a take-up roll
- Finishing: Surface treatments including corona discharge improve printing quality and adhesion
Advantages Over BOPP Film
- Improved sealing properties with higher seal strength
- Enhanced clarity and gloss for better product visibility
- Superior hot tack properties for high-speed packaging machines
- Increased heat resistance for hot-fill and retort packaging
- Higher puncture resistance for enhanced durability
