80μm Base Film 25μm Emboss Depth Yellow-Black Dual-Color CPP Film for High-End Stationery & Industrial Marking

25μm uniform emboss depth, tear-resistant, printable, heat-sealable, durable for high-end stationery & industrial marking/warning applications

Engineered with high-precision co-extrusion casting and premium embossing technology. High-purity CPP resin is molten in a temperature-calibrated extruder (160-180℃), then co-extruded with high-opacity yellow & black masterbatches to form an 80μm high-stiffness dual-color base film (20μm yellow top layer/60μm black bottom layer). After precision cooling and shaping, it undergoes embossing under 100-110℃ & 0.2-0.3MPa for a uniform 25μm fine cloth grain finish, followed by high-power corona treatment, precision trimming and tight winding--yielding defect-free rolls with ultra-low batch deviation (≤3%) for high-end mass production.

• 80μm high-stiffness heavy-gauge base film with 25μm evenly textured emboss depth
• High-visibility saturated yellow-black dual-color with industrial-grade color fastness (72h UV aging, fading grade 1, no cracking/deformation)
• Superior mechanical performance: tensile strength ≥22/20MPa (MD/TD), tear resistance ≥16/13N (MD/TD)
• Shore D hardness 55±3HD, 3M tape-tested emboss adhesion (zero shedding/color loss)
• Corona-treated surface (≥40mN/m) for high-definition printing
• Robust heat seal strength (≥12N/15mm), enhanced oil/moisture barrier
• Food-contact grade compliant (GB 4806.7-2016), odor-free & no harmful precipitation

80μm high-stiffness base film delivers superior structural rigidity + durable toughness, resisting deformation and breakage for long-term medium-heavy use--ideal for high-end application scenarios. 25μm delicate emboss boosts anti-slip tactile grip and visual layering; the high-visibility yellow-black color scheme offers outstanding warning and identification performance, perfect for industrial safety marking. Co-extrusion process ensures permanent color fastness (no fading/bleeding); excellent print/heat-seal compatibility enables seamless post-processing. Food-grade eco-safe, stable mass production, premium quality--blending performance and practicality for high-end industrial and stationery use.

A top-tier choice for high-end stationery (hardcover folder covers, premium notebook shells, luxury album binders) leveraging its high stiffness and exquisite emboss texture; the ultimate option for industrial safety marking & warning tapes (high-visibility yellow-black for clear caution/identification) by virtue of its excellent tear resistance and anti-slip performance. Also applicable to high-end small food packaging (food-safe, enhanced moisture/oil barrier) and medium industrial protective packaging; performs stably in 0℃-65℃ environments, perfectly adapting to high-speed slitting, high-definition digital printing and automated heat-sealing industrial processes.
