Your One-Stop Packaging Material Procurement & Technical Consultation Platform.
Zhongshan Tianchen New Materials Co., Ltd. is a comprehensive packaging material platform built upon more than 20 years of hands-on expertise in the film extrusion, printing, and manufacturing industry. Driven by a commitment to complete vertical integration, we deliver targeted, high-performance packaging solutions for complex global consumer markets.
Through our rigorous quality assurance workflow and collaborative engineering services, we ensure that every batch of PVC shrink film, OPP laminates, and eco-friendly POF shrink film satisfies global compliance specifications. We operate at the intersection of high manufacturing throughput and bespoke engineering, matching our capabilities to the demanding operational timelines of global brands.
At Tianchen, the synthesis of advanced chemical engineering and state-of-the-art mechanical processing allows us to hold gauge tolerances within ±2% on all commercial packaging films. Our specialized R&D team works in tandem with downstream label convertors to optimize print slip coefficients, anti-static metrics, and heat-sealing window configurations.
Our Quality Management System acts as a persistent operational loop. From incoming raw material verification (using DSC thermal analysis to guarantee polymer melt flow indexes) to high-speed optical inspection on our slitting lines, we prevent film surface defects, gels, and thickness variations before products leave the factory floor.
Analyzing physical performance properties, thermal behaviors, and application vectors for heavy industrial, pharmaceutical, and retail environments.
Highly oriented PVC films with transverse direction (TD) shrinkage up to 63% are engineered to conform to contours of complex container geometries. Ideal for premium glass bottles, tamper-evident juice seals, and multi-packs requiring high optical clarity and impact resistance.
Rigid, puncture-proof PVC shrink films provide physical containment and chemical barrier functions for pesticide products. This prevents odor migration and maintains product safety against environmental moisture ingress.
Designed with exceptional oil, chemical, and UV resistance, our films protect decorative designs from deterioration caused by essential oils, solvents, and direct light exposure during extended distribution phases.
PVC (Polyvinyl Chloride) label films are formulated from suspension-grade PVC resin combined with specialized plasticizers, heat stabilizers, and slip additives. Through advanced flat-die or tubular extrusion processes, the polymer chains are stretched (oriented) at precise temperatures below the glass transition point ($T_g \approx 80^\circ\text{C}$).
This locked-in mechanical stress is released when downstream operations apply hot air or steam heat. Our technical roadmap continuously refines the thermal shrinkage curve, allowing a controlled, low-temperature onset ($65^\circ\text{C} - 75^\circ\text{C}$) that prevents product warping while achieving maximum tight-fitting shrinkage at $110^\circ\text{C}$ to $130^\circ\text{C}$.
Our commitment to advanced manufacturing means we utilize multi-layer co-extrusion technology to combine the advantages of multiple polymer layers, yielding a label material with high puncture resistance and optimal surface printability.
Ensures heat-sensitive contents (e.g., dairy products, specialized chemicals) are not degraded during the thermal shrinking tunnel run.
Tailored surface treatments that optimize light dispersion for barcode scannability and shelf presence.
Reduces machine-wear on high-volume automatic sleeve applicators operating at speeds over 600 bottles per minute.
How our centralized manufacturing ecosystem drives down lead times, ensures raw material security, and guarantees stable global logistics.
Our location in Southern China’s chemical processing cluster ensures direct supply lines for PVC resins, plasticizers, and high-gloss pigments. This cushions our global customers from price volatility and guarantees continuous raw material availability.
We configure custom film properties (shrinkage profile, slip coefficient, thickness) in under 7 business days. High-speed slitting machinery and testing lines run continuously, ensuring short lead times from design review to final product shipment.
Proximity to the major shipping ports of Guangzhou, Shenzhen, and Hong Kong guarantees flexible sea, air, and multimodal transport logistics. Customs document handling is managed via integrated IT infrastructures for efficient international shipping.
To ensure optimal functionality and print registration accuracy on high-speed application lines, PVC and other thermo-sensitive films must be stored and handled according to strict operational criteria.
Keep films at a temperature range of 15°C to 25°C. Storing at temperatures exceeding 30°C can trigger premature micro-shrinkage in raw rolls, causing deformation and edge curl during processing. Maintain relative humidity at 40-60% to reduce static accumulation.
Roll stocks must be stored horizontally in their original protective packaging (plastic barrier wrapping and suspended end plugs). Avoid vertical storage to prevent core damage and flat spots on the film surfaces. Keep away from direct sunlight and heat sources.
Ensure the dyne level of the print surface is maintained above 38 mN/m for rotogravure or UV flexo printing. This provides optimal ink anchorage, preventing cracking or peeling during subsequent shrinkage steps in steam or hot-air tunnels.
Get authoritative answers to complex technical questions about our PVC shrink films, packaging applications, and mechanical limits.
PVC (Polyvinyl Chloride) offers excellent optical clarity, high stiffness, and a controlled shrink curve. It is cost-effective and runs well on high-speed label application machinery. However, it requires proper thermal management during storage to prevent premature shrinkage.
PET-G (Polyethylene Terephthalate Glycol) provides the highest shrinkage rates (up to 78%), making it ideal for highly contoured containers. It is highly recyclable and stable across varying temperatures.
POF (Polyolefin) is a co-extruded, environment-friendly film used primarily for outer protective wraps, multi-packs, and direct food packaging rather than printing labels. It has high puncture resistance and tensile strength.
TD shrinkage determines how tightly the label wrap conforms to the bottle's horizontal perimeter. Machine Direction (MD) shrinkage represents the vertical contraction. If MD shrinkage is too high (above 5%), the label will pull upward, distorting printed graphics and text. Our PVC shrink films are optimized for low MD shrinkage (<3%) to ensure visual consistency.
Yes. Our films are manufactured using raw materials and processes that comply with international regulatory frameworks including FDA contact guidelines, REACH SVHC, and EU RoHS standards. We verify compound safety in third-party laboratories to ensure no heavy metal or harmful plasticizer migration occurs under normal processing conditions.
Film blocking is typically caused by high winding tension, storage at elevated temperatures, or insufficient slip additives. We address this during formulation by incorporating precise quantities of anti-blocking agents and silica particles. This creates micro-roughness on the film surface, reducing contact area and ensuring smooth unwinding even under high-humidity conditions.
Our PVC shrink films are compatible with high-speed rotogravure, flexographic (solvent-based and UV-curable), and digital printing processes. The surface energy is treated during production to maintain a dyne level of 38-42 dynes/cm, ensuring excellent ink adhesion and color vibrancy even after shrinkage.
