Explore our certified polymer films engineered for high tensile strength, outstanding clarity, and optimized shrinking profiles.
As dynamic consumer regulations enforce rigid standards on plastic recyclability and chemical migration, the global commercial sector is shifting from traditional vinyl packaging solutions to high-performance polyester derivative films. PET (Polyethylene Terephthalate) and PETG (Polyethylene Terephthalate Glycol) shrink films have emerged as the industry gold standard for complex-shaped containers, multi-pack promotional bundles, and high-speed shrink sleeve labels.
PETG films deliver the highest transverse direction (TD) shrinkage capacity—up to 78%—enabling seamless conformity to extreme container geometries without risk of wrinkling, smiling, or material distortion.
Engineered to support circular economies, our high-density wash-off PET shrink label materials facilitate efficient PET bottle flake recovery. They float off cleanly during recycling wash cycles, preventing bale contamination.
Boasting low haze ratings (<3.5%) and high gloss indices, our films amplify under-the-film shelf appeal. They allow vibrant, high-fidelity rotogravure and flexographic graphics to capture consumer attention.
Supporting multinational manufacturing networks with certified polymer films and continuous output capabilities.
Your One-Stop Packaging Material Procurement Platform with Decades of Manufacturing Integrity.
Zhongshan Tianchen New Materials Co., Ltd. is a comprehensive packaging material platform built on over 20 years of experience in the film packaging industry. Driven by a commitment to resource integration, product quality, and customized solutions, Tianchen serves the precise demands of global B2B procurement professionals.
At Tianchen, quality control is central to our operation. We utilize a modern quality control system that monitors the entire extrusion, slitting, and shipping cycle to verify that all materials conform to strict dimensional tolerances. Combining industrial scale with a dedicated research and development team, we create custom polymer layers designed to operate on automated packaging equipment.
Global procurement teams must balance manufacturing line speeds against material costs and environmental regulations. When sourcing PET shrink films from China, the following parameters define the structural viability of the supplier.
| Material Category | Common Thickness (µm) | Shrink Ratio Range (TD / MD) | Ideal Shrink Temp Range | Primary Industrial Application |
|---|---|---|---|---|
| PETG Label Film | 30 – 50 | TD: 60% – 78% | MD: 1% – 3% | 120°C – 160°C (Steam/Hot Air) | Sleeve labels for contoured glass & plastic bottles |
| POF (Polyolefin) | 12 – 25 | TD: 50% – 65% | MD: 50% – 65% | 130°C – 170°C (Hot Air) | Retail multipacks, books, software, cosmetics |
| PE (Polyethylene) | 35 – 150 | TD: 20% – 40% | MD: 50% – 70% | 160°C – 210°C | Heavy beverage cases, canned goods transit trays |
| PVC Shrink Film | 30 – 70 | TD: 45% – 55% | MD: 2% – 5% | 90°C – 130°C | Tamper-evident seals, cap bands, promotional bundling |
| OPP/CPP Heat Seal | 15 – 40 | N/A (Co-extruded Barrier) | 110°C – 140°C (Seal jaw) | Horizontal flow wrap, dry foods, bakery bags |
We adapt our raw materials and processes to support eco-conscious circular systems and high-efficiency packaging lines.
Integrating up to 30% Post-Consumer Recycled (PCR) PET content back into our premium shrink sleeve films. This integration reduces virgin plastic consumption while maintaining high tensile strength and film clarity.
Formulating specialty films for thin-walled containers. These films prevent bottle collapse or ovalization by initiating shrinkage at lower temperatures and regulating maximum structural pressure.
Optimizing energy use in our extrusion facilities and shifting toward bio-derived plasticizers to help our global supply chain partners meet Scope 3 emissions goals.
Our logistics and quality control protocols help protect material rolls from premature shrinkage and environmental damage during transit.
Because PETG and PVC shrink materials can react to environmental heat, we utilize thermal lining blankets and refrigerated containers (reefers) for shipments during hot seasons or across equatorial routes, protecting against premature roll shrinkage.
Every export lot is documented with food-contact safety declarations, RoHS testing, and REACH chemical compliance. This provides packaging manufacturers with clear regulatory documentation for customs clearance.
We provide exact roll widths, customizable inner core dimensions (typically 3-inch or 6-inch options), and integrated moisture-barrier packaging. This prepares the film for immediate integration into high-speed rotogravure label printers.
Direct technical answers for procurement directors, product engineers, and packaging facility managers.
PETG offers a higher maximum transverse direction (TD) shrinkage rate (up to 78%) compared to PVC (around 50-55%). This makes PETG suitable for packaging with dramatic contours and curves. In addition, PETG is widely accepted in modern municipal recycling streams, whereas PVC is restricted in several regions due to the chlorine components released during processing and disposal.
To prevent premature heat-induced shrinkage, we package our film rolls using reflective thermal insulation blankets. During the hot summer seasons or for transport routes crossing the equator, we recommend shipping via climate-controlled, refrigerated (reefer) container units, maintaining temperatures below 25°C.
Yes. Our technical team can customize polymer blends to achieve specific Transverse Direction (TD) and Machine Direction (MD) ratios. This helps keep printed logos, text, and barcodes proportionally aligned when the sleeve shrinks onto uniquely shaped containers.
Every production batch undergoes continuous on-line thickness scanning, followed by laboratory micro-gauge verification. We maintain thickness tolerances within ±3% to ensure stable performance during high-speed unwind and cutting operations.
