A high-performance 70μm base film with 25μm uniform emboss depth, featuring exceptional tensile strength, tear resistance, printability, and heat-sealability. Ideal for mid-range stationery and industrial marking applications.
Production Process
Manufactured using precision co-extrusion casting and industrial-grade embossing techniques. High-purity CPP resin is melted at 160-180°C and co-extruded with yellow and black masterbatches to create a 70μm dual-color base film (18μm yellow top layer/52μm black bottom layer). After cooling and shaping, the film undergoes embossing at 100-110°C under 0.2-0.3MPa pressure for a uniform 25μm fine cloth grain finish. Final steps include high-power corona treatment, edge trimming, and tight winding, ensuring defect-free rolls with ultra-low batch deviation (≤3%) and consistent industrial-grade performance.
Core Features
70μm medium-stiff base film with 25μm uniform emboss depth
High-visibility yellow-black dual-color with premium color fastness
Superior mechanical properties: tensile strength ≥20/18MPa (MD/TD)
Excellent tear resistance: ≥15/12N (MD/TD)
Shore D hardness: 53±3HD
Corona-treated surface (≥40mN/m) for high-definition printability
Reliable heat seal strength: ≥11N/15mm
Enhanced oil and moisture barrier properties
Food-contact grade compliant (GB 4806.7-2016)
Odor-free with no harmful precipitation
Product Advantages
The 70μm medium-gauge base film provides optimal balance between stiffness and flexible toughness, resisting deformation and breakage for medium-intensity applications. The 25μm delicate emboss enhances anti-slip tactile grip and visual layering, while the high-visibility yellow-black color scheme delivers outstanding marking and warning performance. Co-extrusion ensures permanent color fastness without fading or bleeding, and excellent print/heat-seal compatibility enables seamless post-processing. Food-grade eco-safe, stable mass production, and high cost-performance make this film versatile and durable for various industrial and daily applications.
Application Environment
Ideal for mid-grade stationery including notebook covers, album shells, and file folders due to balanced stiffness and delicate emboss texture. Perfect for general industrial marking and warning tapes with high-visibility yellow-black for clear identification and caution. Also suitable for mid-range small food packaging (food-safe with moisture/oil barrier) and light-to-medium industrial protective packaging. Performs stably in 0°C-60°C environments and adapts perfectly to high-speed slitting, digital printing, and automated heat-sealing industrial processes.
