Your One-Stop Packaging Material Procurement Platform built upon over two decades of technical advancement, rigorous polymer quality control, and client-centric custom design methodologies.
Established on the firm foundation of extensive polymer film processing experience, Tianchen is driven by a deep commitment to global supply chain integration. We resolve custom procurement bottlenecks by manufacturing high-yield, premium-grade PVC, POF, CPP, and OPP films. Our quality management protocols govern every phase of manufacturing, from molecular dispersion of stabilizers to the precision of high-speed slitting equipment.
By combining decades of industry expertise with an agile service philosophy, we provide local support, strict regulatory compliance, and rapid customization to meet the evolving commercial demands of brands in North America, Europe, Asia, and beyond.
Continuous refinement of PVC formulation matrices to provide optimal shrink ratios (up to 58% Transverse Direction) while maintaining high clarity and tear resistance.
Modern quality control laboratories monitor roll profiles, thickness variance (within ±3%), tensile strength, and heat activation thresholds to guarantee error-free performance on automated lines.
Offering a complete catalog of shrink packaging films. From labeling sleeves to protective bulk wraps, we handle custom design, extrusion, slitting, and door-to-door global logistics.
PVC (Polyvinyl Chloride) shrink rolls remain the industrial benchmark for wrap-around labels, tamper-evident neck bands, and high-clarity protective sleeves due to their predictable shrinkage, high gloss, and cost efficiency.
Understanding the mechanical behavior of oriented PVC films is essential for maximizing yields on high-speed applicator machinery. Our PVC shrink films are manufactured using a double-bubble blowing extrusion process. This process stretches the molecular chains in both the Transverse Direction (TD) and Machine Direction (MD) to lock in thermal memory. When exposed to heat during secondary packaging, the polymer chains relax, yielding a tight, uniform shrink-wrap that conforms precisely to complex container contours.
| Property / Characteristic | Standard Range (Low-Mid-High Gauge) | Test Method | Industrial Application Benefit |
|---|---|---|---|
| Thickness Tolerance | 25 to 70 Micron (±3% variance limit) | ASTM D374 | Ensures smooth feeding and prevents jams on high-speed applicator tubes. |
| Transverse Direction (TD) Shrinkage | 50% – 58% (Customizable up to 63%) | ASTM D2732 (at 100°C water bath) | Enables complete shrinkage on highly contoured bottles and jars. |
| Machine Direction (MD) Shrinkage | 1% – 5% | ASTM D2732 | Minimizes vertical distortion of artwork and text during heating. |
| Haze / Clarity Level | < 3.5% (High-Gloss Premium Polish) | ASTM D1003 | Improves brand appearance and allows clean scanning of barcodes. |
| Tensile Strength (TD) | ≥ 75 MPa | ASTM D882 | Prevents splits and tears when labeling sharp-edged or heavy containers. |
| Friction Coefficient (COF) | 0.22 – 0.35 (Kinetic) | ASTM D1894 | Reduces drag on guide rolls for optimal high-speed manufacturing runs. |
By adjusting our compound formulations, we can produce customized film properties, including enhanced UV resistance for outdoor protection, low-temperature activation grades for heat-sensitive contents, and antistatic properties to prevent dust accumulation in cleanrooms.
How Zhongshan Tianchen New Materials Co., Ltd. delivers high performance and cost efficiency to global procurement teams.
1. Raw Material Procurement and Formulation Control: Located in the Pearl River Delta industrial cluster, we source virgin vinyl resins directly from leading petrochemical plants. Our high-capacity mixing lines allow us to maintain precise control over plasticizer ratios, heat stabilizers, and slip agents, protecting our customers from raw material price fluctuations.
2. High-Capacity Advanced Extrusion: Operating state-of-the-art multi-layer co-extrusion blow molding systems, our facility achieves high output while maintaining consistent gauge thickness. Consistent thickness prevents weak points and guarantees uniform shrink forces.
3. Strategic Logistics and Global Distribution: Our proximity to major shipping hubs in Shenzhen, Guangzhou, and Hong Kong allows us to offer flexible, cost-effective shipping options (FOB, CIF, DDP) with short transit times to global destinations.
Ensuring global regulatory alignment and customized solutions for international buyers.
Our PVC shrink roll formulations comply with EU REACH regulations, RoHS directives, and applicable FDA packaging material guidelines. We ensure our materials are free of heavy metal stabilizers (such as lead or cadmium) to support safe industrial and consumer handling.
We provide comprehensive technical support, including assistance with shrink tunnel configuration, film selection based on specific container designs, and on-site or remote machinery troubleshooting to optimize production efficiency.
We supply customized film rolls tailoured to your equipment requirements, offering options for custom core diameters, precise roll lengths, perforated lines, clear or tinted formulations, and specialized print-receptive coatings.
Custom PVC shrink rolls provide reliable barrier protection and strong visual appeal across diverse market sectors.
With Transverse Direction shrinkage of up to 58%, our PVC film conforms smoothly to curved bottles and contoured packaging without wrinkles or ink distortion.
Formulated for controlled longitudinal shrinkage, our films create secure, tight-fitting bands for wine, beverage, and pharmaceutical closures.
Designed for durability and tear resistance, our thicker PVC films provide stable bundling for mosquito coils, heavy batteries, and household goods.
How we balance functional performance with evolving environmental requirements.
The global packaging market is moving toward thinner films to reduce material usage without sacrificing performance. Through precision polymer blending, Tianchen manufactures thin-gauge PVC films that deliver high tensile strength and puncture resistance while reducing raw material consumption.
We also offer alternative formulations like low-temperature shrink POF and high-barrier PET-G to meet specific sustainability requirements. By optimizing the extrusion process, we minimize waste, reclaim production scrap, and help customers transition smoothly between different shrink film materials.
