90μm Base Film 25μm Emboss Depth Red-Black Dual-Color CPP Film for High-End Stationery and Packaging
90μm CPP Red-Black Dual-Color Embossed Film featuring 25μm uniform emboss depth, ultra-stiff construction, high tensile strength, tear resistance, printability, and exceptional durability for high-end stationery applications.
Engineered with high-end co-extrusion casting and precision embossing craftsmanship. High-purity CPP resin is molten in a temperature-calibrated extruder (160-180℃), then co-extruded with red & black masterbatches to form a 90μm ultra-rigid dual-color base film (22μm red top layer/68μm 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—ensuring zero-defect rolls with industrial-grade batch consistency.
- 90μm ultra-stiff base film with 25μm evenly textured emboss depth
- Vivid red-black dual-color with premium color fastness (UV aging 72h, fading grade 1, no cracking/deformation)
- Superior mechanical performance: tensile strength ≥24/22MPa (MD/TD), tear resistance ≥18/15N (MD/TD)
- Shore D hardness 56±3HD, 3M tape-tested emboss adhesion (no shedding/color loss)
- Corona-treated surface (≥41mN/m) for high-definition printability
- High heat seal strength (≥13N/15mm), enhanced oil/moisture barrier
- Food-contact grade compliant (GB 4806.7-2016)
90μm heavy-gauge base film delivers unrivaled structural stiffness + durable toughness, zero deformation for long-term high-intensity use—exceeding high-end application demands. 25μm delicate emboss elevates tactile anti-slip grip and visual premium layering, adding high product added value. Red-black co-extrusion ensures permanent color fastness (no fading/bleeding); high print/heat-seal compatibility enables seamless post-processing. Food-grade eco-safe, heavy-duty oil/moisture resistance, ultra-stable mass production (batch deviation ≤3%)—the ultimate balance of performance and premium quality for high-end scenarios.
A top-tier choice for luxury stationery (hardcover folder covers, premium notebook shells, high-end album binders) leveraging its ultra-stiffness and exquisite emboss texture. Ideal base material for heavy-duty industrial identification tapes (anti-tear, anti-slip, long-service life) and high-end food packaging (food-safe, enhanced moisture/oil barrier). Also applicable to precision heavy-duty industrial protective packaging; performs stably in 0℃-65℃ environments, perfectly adapting to high-speed slitting, high-definition printing and automated heat-sealing industrial processes.
