Explore our primary industrial films engineered for optimal tensile strength, heat responsiveness, and long-term durability. These solutions serve beverage manufacturers, heavy industrial packaging facilities, and customized packaging operations worldwide.
In modern logistics, industrial packaging, and retail product marketing, selecting the proper polymer chemistry is critical to structural integrity, environmental resistance, and economic viability. Polyvinyl Chloride (PVC), Polyolefin (POF), and Polyethylene (PE) represent the core of industrial polymer films. Each material possesses distinct chemical compositions that determine thermal behavior, tear resistance, and tensile modulus.
Historically, PVC has been the standard for retail and display applications. Composed of linear polymer chains containing polar chlorine groups, PVC molecules interact via robust dipole-dipole forces. This micro-structural composition provides high stiffness, extreme clarity (haze index < 1.5%), and an exceptionally sharp shrink profile. It contracts at relatively low temperatures (ranging from 80°C to 130°C), making it compatible with basic heat gun equipment and simplified shrink tunnels.
Polyolefin films are co-extruded polymers that utilize combinations of Polypropylene (PP) and Polyethylene (PE). By using a multi-layer design (typically 3 to 5 layers), POF provides high tensile strength, exceptional puncture resistance, and cold-storage flexibility down to -50°C. It is completely food-safe and does not release hydrochloric acid fumes during sealing operations.
For high-load logistics (such as beverage crates, pallet wrapping, and heavy machinery protection), Polyethylene (particularly Low-Density Polyethylene, LDPE) is preferred. PE provides significant elongation before break (often > 500%), enabling it to secure heavy, uneven pallet loads.
| Polymer Type | Common Density (g/cm³) | Ideal Shrink Range (°C) | Haze Index (%) | Tensile Strength (MPa) | Food Grade Compliance |
|---|---|---|---|---|---|
| PVC (Polyvinyl Chloride) | 1.30 – 1.45 | 85 – 125 | < 1.5% | 45 – 70 | Strict limits (Non-fatty food only) |
| POF (Polyolefin) | 0.92 | 130 – 170 | < 2.0% | 80 – 110 | Approved (FDA compliant) |
| PE (Polyethylene / LDPE) | 0.91 – 0.94 | 150 – 200 | > 5.0% | 20 – 35 | Approved (FDA compliant) |
Zhongshan Tianchen New Materials Co., Ltd. serves as a comprehensive, one-stop packaging material procurement platform. Established with over 20 years of experience in the polymer film packaging industry, Tianchen is built on resource integration, quality management, and customized services to support diverse packaging requirements globally.
Our specialized production, R&D, and sales teams monitor every step of the manufacturing process. Modern quality control systems ensure all products meet global industry standards. Our scale allows us to offer competitive pricing and reliable supply, earning the trust of international partners. Our engineering team continuously refines formulations to improve clarity, tear resistance, and environmental performance.
In competitive global markets, Tianchen operates as a reliable supply chain partner. We provide standard and customized polymer films, heat-shrinkable materials, and high-performance labeling solutions to help businesses optimize their packaging lines and logistics.
The international supply chain demands robust and predictable packaging materials. In regions like North America and the European Union, shipping conditions subject retail goods to extreme temperature swings and high physical stress. High-grade PVC and POF films act as moisture and dust barriers, stabilizing products during long-distance transit.
The automotive supply chain requires highly durable packaging solutions. Standard films often fail due to exposure to mechanical oils, lubricants, and sharp metal edges. We provide cross-linked POF shrink films designed to resist punctures and tearing, protecting critical automotive components from moisture and environmental contaminants during ocean freight.
Food-grade POF shrink film with hot-perforated options facilitates controlled respiration for organic agricultural products, preventing moisture buildup inside the package. Additionally, custom PVC shrink caps provide wine bottles and spirits with tamper-evident seals while maintaining print quality for high-end retail presentation.
For large-scale industrial machinery, structural glass sheets, and beverage cases, thick-gauge PE shrink films provide high elasticity and holding force. This reduces packaging material volume compared to heavy cardboard containers while lowering overall shipping weight.
Exporting polymer films globally requires compliance with strict regional regulatory frameworks. At Zhongshan Tianchen New Materials Co., Ltd., we test all product batches to verify alignment with domestic and international safety standards.
Our high-clarity PVC films are formulated with non-phthalate plasticizers (such as DOTP) to comply with European Union REACH guidelines and RoHS restrictions. This guarantees that imported films do not contain restricted substances of very high concern (SVHC), protecting importers from customs delays or regulatory penalties.
Our POF films are designed to meet FDA Federal Regulation 21 CFR 177.1520. This allows direct food-contact packaging for agriculture, confectionary, and dairy industries, ensuring the material remains chemically inert when exposed to high processing temperatures.
We utilize standardized ASTM testing protocols to verify film performance:
As environmental requirements tighten globally, the plastic film industry is transitioning toward more sustainable manufacturing practices. Zhongshan Tianchen is actively developing next-generation films to address circular economy principles.
We are researching the integration of Post-Consumer Recycled (PCR) and Post-Industrial Recycled (PIR) resins into our PE and POF formulations. Our goal is to reduce reliance on virgin fossil fuel materials while maintaining the clarity and tensile strength required for commercial applications.
We are optimizing the thermal properties of our cross-linked POF films to lower the required activation temperature. Decreasing the necessary heat tunnel temperature by 15°C reduces energy consumption for high-volume packaging lines.
By replacing traditional plasticizers with bio-based ester plasticizers, we produce PVC films that deliver high optical clarity and flexibility while meeting strict chemical safety requirements.
