Product Description
50μm Red Cast Polypropylene Film
Premium food-grade CPP red monochrome film designed for food, medical, and industrial packaging applications requiring ultra-thin gauge performance and vivid color retention.
Production Process
Manufactured using micro-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 red masterbatch, and precision casting into 50μm ultra-thin base film. Final stages include constant-temperature cooling, corona surface activation, micro-edge trimming, and tension-controlled winding for defect-free rolls with ultra-low batch deviation (≤3%).
Core Features
- 50μm ultra-thin lightweight CPP monochrome film with vivid, saturated red hue
- Industrial-grade color fastness (72h UV aging, fading grade 1, no discoloration)
- Superior mechanical performance: high tensile strength, excellent flexible toughness, and anti-tear resistance
- Shore D hardness 49±3HD with corona-treated surface (≥40mN/m)
- Stable heat seal strength (≥9N/15mm) for fast processing lines
- Food-contact grade compliant with GB 4806.7-2016, odor-free, no harmful precipitation
- Reliable moisture/oil barrier and mild chemical resistance
Product Advantages
- Ultra-thin gauge design balances lightweight flexibility with structural durability
- Minimal material consumption, easy to cut, fold, wrap and form
- Saturated high-visibility red for excellent branding and identification
- Permanent color uniformity with no bleeding or fading over time
- Universal print/heat-seal compatibility for seamless post-processing
- Food-grade eco-safe with ultra-stable mass production
- High cost-performance for economical, versatile applications
Application Environment
Ideal for lightweight stationery & crafts, light-duty industrial marking & identification, mini food packaging, daily consumer packaging, ultra-light industrial protective packaging, and retail thin-layer branding materials. Performs stably in 0℃-60℃ environments and adapts to high-speed slitting, roll-to-roll digital printing, and automated mini-packaging processes.
