50μm Translucent Blue CPP Plastic Film with High Seal Strength for Industrial Packaging

50μm CPP semi-transparent blue film engineered for superior performance in delicate applications requiring both functionality and visual appeal.

Manufactured using micro-precision co-extrusion casting technology with high-purity food-grade CPP resin. The process involves temperature-calibrated extrusion (160-180℃) with uniform color dispersion, precision cooling, and controlled winding to produce defect-free rolls with ultra-low batch thickness deviation (≤3%).

• 50μm ultra-thin lightweight construction with semi-transparent blue hue
• Industrial-grade color fastness with 72h UV aging resistance
• Superior mechanical performance: high tensile strength and flexible toughness
• Shore D hardness 48±3HD with excellent anti-tear resistance
• Mild corona-treated surface (≥38mN/m) for high-definition printing and lamination
• Stable low-temperature heat seal strength (≥9N/15mm)
• Food-contact grade compliant with GB 4806.7-2016 standards
• Reliable moisture barrier and mild chemical resistance

Achieves optimal balance of light weight, flexible ductility, and aesthetic translucency. Micro-blended color formulation ensures consistent semi-transparent blue tone without color bleeding or fading. Food-grade safety with universal processing compatibility makes it ideal for premium applications requiring both functionality and visual aesthetics.

• Delicate stationery & crafts: gift wrapping, decorative linings, DIY materials
• Light-duty transparent industrial marking & color coding
• Mini food packaging: candy wrappers, chocolate inner packaging, snack sachets
• Premium consumer packaging: jewelry, cosmetic samples, perfume trial kits
• Ultra-light industrial protective packaging for precision components
• Retail branding materials and product display linings

Stable performance in 0℃-60℃ environments, compatible with high-speed micro-slitting, digital printing, and automated packaging processes.
