Established with a commitment to cross-regional resource integration and addressing complex global procurement needs, Tianchen delivers highly optimized barrier and shrink film solutions for top-tier international businesses.
Our professional production, research, development, and sales teams execute strict quality control programs at every stage. With large-scale modern manufacturing and automated thickness control systems, we ensure compliance with international standard tolerances, delivering durable, highly functional polymers to global brands.
Integrating deep processing capabilities with reliable manufacturing to build stable supply systems.
Our manufacturing and R&D engineers possess over two decades of polymer extrusion expertise. Working closely with international raw material suppliers, we develop customized compounds that optimize tensile strength, shrinkage rates, and low-temperature sealing parameters.
We streamline international procurement by coordinating manufacturing, testing, export documentation, and customs clearance. Our products span PVC, POF, PE, and OPP films, ensuring high compatibility across diverse packaging lines.
Equipped with optical defect inspection scanners and mechanical tear testers, we eliminate surface gels, fisheyes, and thin spots before products ship, assuring smooth operations on automated packing systems.
How molecular design, orientation processes, and ecological additives elevate modern PVC and POF films.
In modern industrial packaging, PVC Sheet Films and Shrink Materials are evaluated on optical clarity, uniform shrinkage behavior, mechanical strength, and environmental compatibility. By controlling the polymer chain orientation during the biaxial stretching process, we align the molecules to build high shrink tension along both MD (Machine Direction) and TD (Transverse Direction).
Historically, PVC manufacturing depended on heavy-metal stabilizers (lead/cadmium) to prevent thermal degradation during extrusion. Our current production lines utilize advanced Calcium-Zinc (Ca-Zn) organic stabilizers and high-molecular-weight polymeric plasticizers (such as DOTP and Epoxidized Soybean Oil - ESBO). This development ensures that our PVC films maintain superior thermal stability and clarity without leaching harmful phthalates, meeting food-contact and chemical-safety regulations (REACH/RoHS) globally.
By heating extruded PVC sheets below their melting point and stretching them under high tension, our processing machinery traps mechanical strain within the polymer network. When re-heated at packaging lines (typically between 110°C and 150°C), the internal stresses release, causing the film to shrink tightly around complex geometries. Our PVC and POF films deliver stable shrink curves, preventing product deformation on fragile items like notebooks or thin plastics while providing tight seals on heavy metal cans.
| Film Material Type | Shrink Ratio (TD / MD %) | Tensile Strength (MPa) | Haze Value (%) | Optimal Shrink Temp Range | Key Performance Strengths |
|---|---|---|---|---|---|
| PVC Shrink Film (Rigid/Semi-Rigid) | 45% - 55% / 10% - 15% | ≥ 45 MPa | < 2.5% | 110°C - 130°C | Excellent clarity, low-temperature shrink initiation, rigid finish. |
| POF Heat Shrink Film | ≥ 60% / ≥ 60% | ≥ 80 MPa | < 1.5% | 130°C - 160°C | High puncture resistance, FDA compliant, eco-friendly, strong seal. |
| OPP Heat Sealable Film | Minimal (Designed for wrap-around) | ≥ 110 MPa | < 2.0% | 115°C - 140°C | High moisture barrier, high speed runs, excellent printability. |
| PE Shrink Film (Heavy-Duty) | 20% - 35% / 50% - 60% | ≥ 22 MPa | < 8.0% | 160°C - 180°C | Extreme puncture resistance, holds heavy multipack beverages. |

Engineered polymer solutions supporting automated assembly lines across multiple industry sectors.
Applying Hot Perforation POF Shrink Film allows moisture and heat to escape during high-speed packaging. This design prevents mold andcondensation, keeping fresh food and agricultural goods safe throughout shipping.
Our PVC shrink labels are engineered for printability. The high TD shrinkage (up to 55%) enables the sleeve to fit contoured beverage bottles, cosmetics, and household items, maintaining design symmetry without ink cracking.
Heavy-duty custom PE shrink films package canned beverages, bottled water, and construction products. By replacing corrugated shipping cartons, these tough plastic films lower total packaging weight and reduce carbon footprints.
How Zhongshan Tianchen leverages automation and process control to maintain stable global lead times.
Operating a sustainable supply chain in the polymer field requires more than just mass-production. By incorporating automated controls, Zhongshan Tianchen maintains consistent film quality that supports seamless processing on our clients' wrapping and printing lines.
Beta-ray gauge sensor arrays monitor film thickness in real-time, instantly correcting die gaps to stay within ±3% of nominal target.
Optical camera inspection systems scan moving webs at high speed to spot, flag, and record gel specs, carbon dots, or punctures.
Multi-stage tension control zones manage winding processes to prevent roll telescoping, core crushing, and structural stretching.
Close integration with deepwater container ports in South China (Shenzhen/Guangzhou) ensures efficient global shipping logistics.
This automated production framework enables us to offer high quality products at competitive price points. By eliminating manufacturing defects early, we help our partners reduce downtime, increase line speeds, and lower overall waste.
Providing the documentation and verification international buyers need for stable compliance.
Importing polymer packaging materials requires strict alignment with local health, safety, and environmental laws. Working with a reliable, certified supplier is essential to keeping your supply chain compliant and running smoothly.
Additionally, we assist our global clients with customs clearance paperwork, including HS code classifications, COA (Certificate of Analysis) declarations, and optimization of shipping container volumes to lower shipping costs.
Answering common questions from packaging engineers, purchasing managers, and logistics operations.
A1: PVC (Polyvinyl Chloride) is a rigid, clear film that shrinks at low temperatures (110°C - 130°C). It is often used for printed labels, bottle sleeves, and items like DVDs. POF (Polyolefin) is a strong, highly flexible, multi-layered film. It has high tear resistance, is biodegradable, and meets FDA standards for direct food contact. POF requires higher shrink temperatures (130°C - 160°C) and is commonly used for food, cosmetics, and bundling products.
A2: PVC shrink films are heat-sensitive. Storing them in areas warmer than 30°C (86°F) can cause the film to shrink slightly on the roll, leading to blockiness, deformation, or unwind issues. We recommend storing rolls in a climate-controlled warehouse below 25°C (77°F) with relative humidity between 40% and 60%.
A3: After eggs or warm bakery goods are packaged, they release moisture. Without ventilation, condensation builds up inside the film, which can lead to mold and spoil the food. Hot perforation adds clean, melt-locked micro-holes to the POF film. This allows moisture to escape while maintaining the film's strength and protecting the product.
A4: For first-time custom prints, lead time ranges from 15 to 20 days. This allows for artwork verification, gravure cylinder preparation, test print alignment, and production. Re-orders typically ship within 10 to 12 days, depending on batch volume.
