50 micron translucent yellow or opaque yellow cast polypropylene (CPP) film is a sturdy and durable packaging material designed for food, medical, and industrial packaging applications.
Primary Applications
Food Packaging: Protects food from oxygen and moisture while providing an attractive yellow appearance that enhances consumer appeal.
Stationery Packaging: Ideal for packaging pens, pencils, and markers with high clarity and stiffness to prevent damage during transportation.
Medical and Pharmaceutical Packaging: High moisture and gas barrier properties ensure contents remain sterile and protected.
Industrial and Heavy-Duty Packaging: Suitable for machinery parts, construction equipment, and industrial items requiring long-distance transport protection.
Packaging of Chemicals: High gas barrier properties provide secure sealing for hazardous materials.
Retail Packaging: Enhances product visibility and accessibility for consumer retail applications.
Key Features
Cast polypropylene film offers excellent transparency, high gloss, and superior moisture barriers, making it ideal for applications where product visibility is essential. The material is highly durable, flexible, and features excellent sealing properties for heat sealing applications. CPP film demonstrates exceptional resistance to punctures, tearing, and abrasion, ensuring reliable performance during rough handling in transportation.
Additional benefits include good stiffness and dimensional stability to prevent shrinking or stretching during processing, consistent printability for high-quality graphics, and excellent clarity for effective branding elements on packaging.
Manufacturing Process
Polymerization: Propylene monomers are polymerized under pressure and high temperature to produce polypropylene resin pellets.
Extrusion: Polypropylene resin pellets are melted and extruded through a flat die to form a thin, continuous sheet.
Orientation: The extruded sheet is stretched across machine and transverse directions to enhance mechanical properties and clarity.
Cooling: The 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: Higher seal strength makes CPP ideal for food packaging applications.
Enhanced Clarity: Superior clarity and gloss compared to BOPP film for better product visibility.
Better Hot Tack Properties: Enables use in high-speed packaging machines requiring quick sealing.
Increased Heat Resistance: Better suited for hot-fill and retort packaging applications with high temperatures.
Higher Puncture Resistance: Enhanced durability and resistance to damage during transportation and storage.
