Under the hood of multi-layer co-extrusion: How BOPP, CPP, and high-barrier polyolefins are engineered at the molecular level.
Our flagship co-extruded OPP (BOPP) films utilize a highly structured multi-layer architecture. The central core layer (B) consists of highly crystalline polypropylene homopolymer to deliver optimal rigidity and tensile strength. The surrounding functional skin layers (A & C) are formulated with ethylene-propylene-butylene terpolymers, enabling low heat-sealing thresholds, high hot-tack performance, and precise slip properties.
By executing sequential stretching (tenter frame process) in both the machine direction (MD) and transverse direction (TD), we realign the polymer chains. This molecular orientation process results in superior clarity, high gloss, excellent puncture resistance, and highly controlled mechanical properties. These characteristics are critical for trouble-free, high-speed runs on horizontal/vertical form-fill-seal (HFFS/VFFS) systems.
To support clean, high-speed rotogravure, flexographic, and digital printing, our films undergo inline gas-phase corona treatment. This increases surface tension to ≥38 dynes/cm. The treatment is engineered for long-term stability, resisting decay during transit and storage. This ensures reliable ink adhesion, clean lamination, and prevents peeling in multi-layer structures.

How our co-extruded films and specialized shrink solutions resolve critical packaging bottlenecks across diverse industry sectors.
For fresh produce, bakery, and dairy, our hot-perforated POF films and high-barrier OPP heat-sealable films regulate internal humidity while preventing mold and moisture build-up. This extends product shelf life across the cold chain.
We supply high-purity, dust-free POF and PVC shrink materials that maintain package integrity under sanitization. Excellent puncture resistance keeps pharmaceutical outer bundles secure, tamper-evident, and sterile during shipping.
Heavy-duty PE shrink wraps and heavy product packaging films provide high load retention for pallets, construction materials, and bulk chemicals. These films resist tearing under mechanical pressure and protect products from wind and rain.
High-gloss, glass-like clarity PVC and POF films enhance the visual appeal of cosmetics and beverages. Advanced multi-pack bundling ensures stability on retail shelves, while custom wine bottle caps provide a secure fit and clean aesthetic.
By integrating advanced automation and data-driven process controls, Zhongshan Tianchen New Materials Co., Ltd. ensures consistent product quality and reliable supply chains for global customers.
Our extrusion lines feature real-time radiometric sensors that monitor thickness cross-profiles every millisecond. The system automatically adjusts the extrusion die lip to maintain thickness variations within ±3%.
Located in Zhongshan, Guangdong, we have direct access to key shipping hubs in Shenzhen, Nansha (Guangzhou), and Hong Kong. This reduces inland transit times, lowers logistics costs, and speeds up international shipping.
Our production systems feature clean regenerative thermal oxidizers (RTO) to manage emissions and heat-recovery units to lower our carbon footprint, supporting sustainable manufacturing practices.
Meeting international food contact regulations, chemical safety guidelines, and environmental standards for easy customs clearance.
Our co-extruded packaging films are manufactured using raw materials that meet FDA (US FDA 21 CFR 177.1520) and EU 10/2011 standards, ensuring they are safe for direct contact with food.
Our products are certified free of heavy metals, phthalates, and restricted substances. We maintain updated REACH and RoHS compliance certificates from SGS testing labs.
We provide complete documentation, including Certificates of Origin (CO, Form E, Form F) and customs-friendly hs-code categorization, to help streamline clearance and reduce tariff costs.
Expert technical answers to common queries regarding co-extruded films, polymer behavior, and sourcing logistics.
Single-layer films are extruded from a single polymer, limiting their properties. Co-extruded OPP (such as our A/B/C structure) combines different resins in a single process. This allows us to optimize the core layer for stiffness and tensile strength, while configuring the outer skin layers for low sealing temperatures and adjusted coefficient of friction.
We use inline high-power corona treaters during the tenter frame orientation process. We control the humidity and air temperature in our slitting facility to prevent treatment decay. This ensures our films maintain a surface tension of ≥38 dynes/cm for at least six months when stored under cool, dry conditions.
We recommend storing films in their original packaging at temperatures between 15°C and 25°C, away from direct sunlight and heat sources. When stored correctly, POF and PVC shrink films have a shelf life of 12 months. PE shrink films can be stored for up to 24 months.
Yes, our R&D department can adjust shrink ratios (up to 75% in the machine direction) and sealing temperatures by modifying the polymer formulation. This is useful for high-speed tunnels or heat-sensitive products like wines, eggs, and chocolates.
