Zhongshan Tianchen New Materials Co., Ltd. – Your One-Stop Packaging Material Procurement Platform.
Zhongshan Tianchen New Materials Co., Ltd. is a one-stop packaging material procurement platform established on the basis of more than 20 years of experience in the film packaging industry. Established on the foundation of extensive industrial orientation and molecular extrusion expertise, Tianchen is driven by a commitment to comprehensive resource integration and the absolute optimization of customer manufacturing lines. We assure that our clients receive the most robust, high-yielding, and cost-effective solutions for diverse modern packaging layouts.
Integrating polymer manufacturing breakthroughs with responsive industrial logistics allows our international clients to improve line speeds, eliminate heat-sealing failures, and dramatically reduce materials waste.
At Tianchen, we run state-of-the-art production, advanced polymer research, and global sales channels. Quality control is built into every step. Our modern testing systems verify tensile strength, tear propagation, and optical haze metrics on every batch to ensure that our materials exceed international quality standards.
Integrating raw material compounding, dynamic co-extrusion, slitting, perforation, and shipping under a single workflow. We eliminate intermediate logistics friction, enabling custom order fulfillment (from custom formulations and slip modifiers to customized widths) with fast lead times.
Over two decades of experience in packaging development. Our engineers help minimize machine downtime on high-speed lines through tailormade products. We design products featuring balanced shrinkage rates and low sealing-temperature thresholds, perfect for thermal-sensitive products.
An in-depth look at molecular orientation, chemical compounding, and thermal shrinkage kinetics.
Heat-shrinkable plastic films depend on molecular memory built during the manufacturing process. For both Polyvinyl Chloride (PVC) and Polyolefin (POF) films, the polymer chain structure is stretched and oriented at specific temperatures above their glass transition points ($T_g$). When cooled rapidly under tension, these stretched polymer structures lock in place. Reheating them relaxes the chains, causing the film to shrink tightly around the contours of your product.
PVC (Polyvinyl Chloride) relies on plasticized formulations to achieve the flexibility needed for shrink packaging. Traditional plasticizers (like phthalates) are being phased out in modern production. At Zhongshan Tianchen, our green PVC formulations use non-toxic, eco-friendly plasticizer alternatives like DOTP (Dioctyl Terephthalate) and epoxidized vegetable oils. This ensures that our PVC films remain fully compliant with European Union REACH and RoHS standards, protecting end consumers without losing the high gloss, clarity, and low-temperature shrinking properties that PVC is known for.
Conversely, POF (Polyolefin) film utilizes a multi-layer co-extrusion process—typically combining Linear Low-Density Polyethylene (LLDPE) as the core strength layer with Polypropylene (PP) copolymer outer layers. This structure provides high puncture resistance and high seal strength. For applications that require high tear resistance and tight, clean shrink wraps, our cross-linked POF films use electron-beam radiation to link the polymer chains. This makes the material highly resistant to hot-wire burning and tearing, even around sharp edges.
Our extrusion lines carefully balance tensile stretching across the Machine Direction (MD) and Transverse Direction (TD). This precise calibration prevents puckering, dog-ears, and thin spots when packaging uneven shapes.
By shifting the temperature window down to 110°C - 130°C for specialty lines, our materials help lower energy costs on shrink tunnels and prevent damage to heat-sensitive products like cosmetics, chocolates, and medicines.
We apply corona treatments to adjust the film's surface energy, ensuring optimal printability. We also maintain a low COF (typically between 0.20 and 0.30) to keep high-speed automated packaging machinery running smoothly without jams.
How customized film formulations solve specific issues in global retail, industrial, and food sectors.
Fast-Moving Consumer Goods require packaging materials that can keep pace with automated operations. Our POF films feature high-speed heat sealing and quick shrinkage, allowing lines to process up to 120 packs per minute with minimal film breaks. This ensures high-clarity retail presentations for multipacks, promotional items, and display boxes.
For fresh produce, bakery products, and poultry packaging, controlling moisture buildup is essential. Our hot-perforation POF films feature uniform, micro-perforated holes that allow heat and steam to escape, preventing condensation and extending product shelf life. These materials comply with FDA standards for direct food contact.
Maintaining security and product integrity is vital for medical items, high-end cosmetics, and volatile liquids. Our high-shrinkage PVC film can be customized into cut sleeves and dome bags. It provides tight, tamper-evident neck bands and cap seals that shrink securely around complex bottle curves and pump caps, protecting products against contamination.
We understand that no two automated packaging setups are identical. Our engineering team can fine-tune film attributes—including slip additive ratios, density layers, anti-fog coatings, and customized perforation patterns—to match your specific equipment setup, wrapping speed, and environmental conditions.
Robust production capacity and quality controls backed by 20+ years of industrial polymer experience.

Leveraging smart automation and integrated logistics to optimize B2B procurement budgets.
Our factory in Zhongshan features advanced automation controls that manage temperature profile zones across our extruders. This real-time feedback loop ensures consistent thickness tolerances of $\pm 3\%$, preventing common issues like thin spots, film breaks, or sealing failures.
Located in the Pearl River Delta, our facility benefits from mature polymer chemical supply chains and direct access to major international ports (including Guangzhou, Shenzhen, and Hong Kong). This helps us secure raw resins at competitive prices, minimize lead times, and optimize shipping arrangements, passing those efficiency savings directly to our clients.
Additionally, we maintain a raw resin safety stock equivalent to 30 days of production. This ensures stable production timelines and pricing, protecting our clients from volatility in global shipping and chemical markets.
Meeting environmental, health, and shipping requirements for global markets.
Our POF films are manufactured in cleanroom-compliant environments using high-grade resins that meet FDA requirements. This makes them safe for direct packaging of bakery products, poultry, eggs, and dynamic multi-packs.
We use non-phthalate plasticizers (such as DOTP) to ensure our PVC materials comply with EU REACH regulations and RoHS directives, providing safe packaging options for consumer markets.
Our quality management systems govern every step of our process—from testing incoming raw materials to checking roll dimensions, wind tension, and carrying out post-slitting verification trials.
Developing thin-gauge materials and functional barrier additions for next-generation packaging.
The shrink packaging industry is moving toward circular-economy designs and thinner-gauge materials. At Zhongshan Tianchen, we are actively developing advanced downgauging techniques. By restructuring our co-extrusion layering, we have introduced a high-tenacity, 10-micron POF film that delivers the puncture resistance and holding force of traditional 15-micron films. This enables brands to reduce plastic consumption by 33% per pack, lowering materials costs and carbon footprint metrics.
Additionally, we are testing bio-based polyethylene compounds derived from renewable plant sugars. These materials offer identical performance to conventional LLDPE in heat-shrink setups, making it easier for brands to transition to sustainable packaging. We are also optimizing recycled PVC formulations to reuse post-industrial clean waste, helping reduce raw oil extraction.
We are also focused on barrier functionality. Our R&D team is working on multi-layer films that feature oxygen-barrier additives. These films help preserve food freshness and block moisture transfer, protecting sensitive products without the need for thick, non-recyclable multi-material laminates.
