Explore our technical portfolio of industrial-grade heat shrink films, engineered for exceptional clarity, structural integrity, and high shrinkage rates.
Understanding Polymer Rheology, Biaxial Orientation, and Mechanical Performance of OPP vs. Polyolefin (POF) and PVC Films.
Oriented Polypropylene (OPP) and Biaxially Oriented Polypropylene (BOPP) are renowned for their high tensile strength, excellent moisture barrier properties, and superior optical clarity. Standard BOPP is engineered for dimensional stability; however, specialized shrinkable OPP formulations are designed with high tension profiles, providing structural reinforcement, moisture protection, and tamper evidence for retail products, cosmetics, and premium multi-packs.
Our five-layer co-extrusion technology blends Linear Low-Density Polyethylene (LLDPE) and Polypropylene (PP) resins to yield highly durable, cross-linked Polyolefin shrink films. The molecular cross-linking process uses electron-beam irradiation to modify the polymer structure, enhancing puncture resistance, enabling low temperature shrink initiation, and preventing 'dog ears' or corner voids in irregularly shaped consumer items and automotive components.
Polyvinyl Chloride (PVC) heat shrink film remains the industry standard for high-clarity promotional packs, battery sleeves, and wine bottle caps due to its low shrink temperature and excellent shape conformation. For heavier, multi-unit collation requirements (such as case packaging for canned beverages), Polyethylene (PE) shrink films provide the necessary density, elasticity, and high-holding force required for palletized shipping and heavy distribution loops.
"The choice between POF, PVC, and OPP must align with the mechanical load of the package, the thermal sensitivity of the product, and the specific dynamics of high-speed L-bar or continuous side sealers." - Technical Director, Zhongshan Tianchen New Materials Co., Ltd.

| Film Material Type | Shrink Temperature Range (°C) | Shrink Ratio (MD / TD %) | Tensile Strength (MPa) | Optical Haze (%) | Key Applications |
|---|---|---|---|---|---|
| Specialized Shrink OPP | 110 - 140 | 30 - 50 / 30 - 50 | 120 / 230 | 1.5 - 2.5 | High-speed overwrap, cosmetics, CD/DVD sleeves, premium tamper seals |
| Cross-Linked POF | 120 - 160 | 60 - 70 / 60 - 70 | 90 / 95 | 1.2 - 2.0 | Automotive, consumer electronics, multi-packs, fresh food packaging |
| Standard PVC | 80 - 120 | 40 - 50 / 40 - 50 | 45 / 50 | 2.0 - 3.5 | Wine bottle caps, battery sleeves, pharmaceutical boxes, crafts |
| LDPE Collation | 160 - 190 | 50 - 70 / 10 - 20 | 20 / 18 | 8.0 - 12.0 | Beverage crates, heavy structural packages, pallet containment shipping |
Customized polymer properties engineered to meet the operational demands of diverse industries worldwide.
For fresh eggs, bakery items, and consumer food items, we engineer hot-perforation POF films. The micro-perforations allow hot air to escape during sealing while maintaining barrier properties, preventing moisture condensation and extending product shelf life.
Industrial automotive parts are prone to abrasion, corrosion, and oil residue. Our heavy-duty POF films are formulated with high-puncture resistance to protect sharp metal components, ensuring intact shipping and distribution.
Medical and cosmetics packaging requires reliable tamper-evidence and high-speed sealing capability. Our high-clarity PVC and low-temperature POF films ensure clean, hermetic seals on high-speed continuous packaging lines.
Cosmetics, books, and promotional multipacks depend on high optical gloss and low haze for shelf appeal. Our specialized OPP shrink films provide a tight, wrinkle-free fit with exceptional transparency that enhances graphics and branding.
Heavy goods, building supplies, and aerosol cans utilize thick LDPE and cross-linked films to prevent rupture during transit. Our formulations withstand puncture and environmental exposure, ensuring stable shipping and load containment.
Zhongshan Tianchen New Materials Co., Ltd. – Your One-Stop Packaging Material Procurement Platform
Zhongshan Tianchen New Materials Co., Ltd. is a comprehensive one-stop packaging material procurement platform established on the basis of more than 20 years of experience in the film packaging industry. Driven by a commitment to resource integration and addressing customer needs, Tianchen ensures that it offers the finest solutions for diverse packaging requirements.
By leveraging our deep industry knowledge, we manage the entire value chain from polymer compounding to final slitting and logistics. This integrated approach allows us to supply consistent quality and provide customized shrink film configurations that optimize processing speeds on automatic packaging equipment.
At Tianchen, we have professional production, research and development, and sales teams, so quality control is taken very seriously. The modern quality control system implemented within the company ensures that all products meet the customer’s standards. This commitment to quality, combined with large-scale production capabilities, has garnered significant favor and trust from customers. Our experienced professionals continuously work to innovate and improve product offerings, ensuring that we always deliver the best to our clients.
How automated extrusion, real-time thickness profiling, and raw material access secure production runs.
Pioneering sustainable barrier chemistries and ultra-thin high-yield packaging films.
We are actively developing shrink film structures that incorporate up to 30% recycled content. By sourcing high-quality post-consumer resins and optimizing the co-extrusion profile, we maintain clarity and tensile properties while helping brands reduce carbon footprint and meet plastic tax compliance mandates worldwide.
Through raw material selection and advanced cross-linking, we are shifting the industry standard from 19-micron and 15-micron films to 12-micron and 9-micron films. These thinner options deliver comparable puncture resistance and seal strength, offering cost savings and reducing material use by up to 40%.
Our research team is testing PLA (Polylactic Acid) and PHA (Polyhydroxyalkanoate) shrink blends. Our goal is to commercialize a fully compostable shrink film that performs reliably in standard heat tunnels, supporting circular packaging initiatives.
Simplifying complex regulatory compliance and international shipping requirements for procurement teams.
Procuring raw materials globally requires compliance with strict safety regulations. Zhongshan Tianchen New Materials Co., Ltd. ensures that all our products comply with international directives, including FDA food contact approvals, EU Regulation 10/2011, REACH, RoHS, and California Proposition 65.
We provide full traceability, technical data sheets (TDS), certificates of analysis (COA), and compliance documentation with every shipment. This rigorous oversight ensures hassle-free customs clearance and protects brand reputation in markets like North America, Europe, and Asia-Pacific.
To mitigate shipping delays and logistics risks, we offer customized inventory solutions, including safety stock programs, blanket ordering, and regional warehouse options. Whether your plant utilizes continuous L-bar sealers or high-speed side sealing lines, our films are packaged with desiccant protection and impact-resistant cores to ensure they arrive ready for production.
