80μm Blue Food Grade Cast Polypropylene Film for Industrial and Medical Packaging

High-performance food-grade CPP film engineered for food, medical, and industrial packaging applications with vivid blue coloration and superior mechanical properties.

Manufactured using precision co-extrusion casting technology with high-purity food-grade CPP resin. The process involves temperature-calibrated extrusion (160-180℃), homogeneous blending with UV-stable cobalt blue masterbatch, and high-precision casting into smooth 80μm base film. Final steps include constant-temperature cooling, corona surface activation, edge trimming, and tension-controlled winding to produce defect-free rolls with ultra-low batch deviation (≤3%).

• 80μm medium-gauge CPP monochrome film with vivid, saturated blue hue
• Industrial-grade color fastness (72h UV aging, fading grade 1)
• Superior mechanical performance: tensile strength ≥22/20MPa MD/TD
• Excellent tear resistance: ≥16/13N MD/TD
• Balanced stiffness and flexibility with Shore D hardness 55±3HD
• Corona-treated surface (≥40mN/m) for direct printing and lamination
• Robust heat seal strength (≥12N/15mm) for automated processing
• Food-contact grade compliant with GB 4806.7-2016 standards
• Enhanced moisture/oil barrier and mild chemical resistance

The 80μm medium-gauge design provides optimal balance of structural rigidity and flexibility, resisting deformation while remaining easy to process. Saturated blue coloration offers excellent branding and identification capabilities. Co-extrusion blending ensures permanent color uniformity without bleeding or fading. Universal compatibility with printing and heat-sealing processes enhances production efficiency and reduces processing costs. Food-grade eco-safe material with ultra-stable mass production delivers high cost-performance for diverse applications.

Ideal for high-grade stationery and office supplies, industrial color-coded marking and identification, medium-sized food packaging, premium consumer product packaging, industrial protective packaging, and commercial branding materials. Performs stably in 0℃-65℃ environments and adapts perfectly to high-speed slitting, digital printing, and automated packaging processes.
