Explore our high-performance polyolefin, PVC, and co-extruded product lines, manufactured to international ASTM packaging standards.
A One-Stop Global Packaging Sourcing Platform Founded on Decades of Extrusion Expertise.
At Zhongshan Tianchen New Materials Co., Ltd., we run integrated production, research and development, and technical sales teams to address complex packaging challenges. Quality control is built into every phase of extrusion, stretching, rewinding, and printing. The modern QA/QC infrastructure implemented within our company ensures that all POF, PE, and PVC shrink films meet custom requirements for high-speed automated packaging runs.
By scaling production capacity while maintaining tight thickness and dimensional tolerances, we have earned the long-term trust of international distributors and high-volume end-users in food, automotive, and electronics industries.
Finding a reliable supplier for specialized films (like cross-linked low-temperature POF shrink film or thick industrial PE film) can be challenging. As a dedicated one-stop packaging material procurement platform, Tianchen integrates production lines and raw-material procurement to provide highly customized solutions. Whether you require eco-friendly POF shrink film, food-grade hot perforation barrier film, or durable PVC label caps, we optimize the entire supply chain to lower your landing costs and protect your margins.
How technical shifts and sustainability regulations are shaping the modern wholesale packaging industry.
Rising raw polymer costs have driven research into downgauging. Using advanced multi-layer co-extrusion technology, manufacturers can produce thinner films (down to 10 or 12 microns) that retain the tensile strength and puncture resistance of older 15 or 19-micron configurations.
Global regulatory bodies, especially in the European Union (under the PPWR directive), are pushing for mandatory recycled content in transit and collation packaging. Factories are modifying extrusion screws to incorporate 30% to 50% PCR LDPE without compromising shrink ratios or optical clarity.
Reducing energy consumption in packaging lines is a priority for high-volume factories. The latest generation of POF films feature low-temperature initiation chemistry, shrinking at 110°C to 120°C rather than standard 150°C. This lowers utility costs and protects temperature-sensitive goods like confectionery, chemicals, and cosmetics.
A deep dive into polymer compositions and their respective physical mechanical properties.
Adapting polymer formulations to match your automated processing environments.
In high-speed, continuous-motion automated packaging systems (such as those running over 100 packs per minute), film performance is critical. Lower-quality films can leave residue on seal bars, leading to carbon build-up and sealing failures. Our cross-linked POF shrink film is engineered to withstand extreme seal bar temperatures, providing clean, smoke-free cuts and high seal strength.
For heavy transit packaging, like industrial water bottle cases or building materials, thick LDPE shrink films are the standard. The film must deliver high holding force (retention force) to prevent cargo shifting during transport. Tianchen's co-extruded heavy-duty PE films offer optimized shrink-force ratios, eliminating the need for corrugated trays and lowering secondary packaging costs.
Friction control (Coefficient of Friction - COF) is essential for automated conveyor systems. If a film is too tacky, packs can stick, causing jams on the line. If it is too slippery, stacked pallets will be unstable. We calibrate kinetic and static COF (ranging from 0.15 to 0.30) to meet the specifications of your processing machinery.
Standard polyolefin shrink film is made of individual polymer chains that slide past each other under stress or heat. Cross-linked film undergoes a process where the polymer structure is irradiated, forming covalent chemical bonds between the molecular chains.
This structural modification yields significant performance improvements:
Ensuring compliance, documentation, and technical support for smooth international logistics.
Any packaging materials direct-contacting foodstuffs (like our perforated egg shrink films) must meet stringent global standards. Tianchen's raw resins are fully compliant with FDA 21 CFR 177.1520 regulations and EU Regulation No. 10/2011, assuring safety for food contact packaging.
For chilled products, condensation can form inside the film, reducing product visibility and accelerating spoilage. We formulate high-performance anti-fog POF and PE films, keeping the packaging clear in cold display cases.
Exporting plastic rolls globally requires careful container optimization to prevent core crushing or deformation during maritime transit in high-temperature zones. We utilize heavy-walled cardboard cores, plastic roll plugs, and moisture-resistant barrier wrapping to ensure every shipment arrives ready for production.
Tianchen's development pathway toward sustainable, high-performance shrink materials.
Scaling up the production of polyolefin shrink films with up to 50% post-consumer recycled content, while developing bio-sourced resins (derived from plant lipids) to reduce carbon footprints.
Transitioning from 3-layer and 5-layer co-extrusion structures to 9-layer and 11-layer nano-microlayer structures. This allows for thinner films with improved barrier and mechanical performance.
Integrating surface treatments to support embedded printed electronics, conductive inks, and interactive security matrices directly onto shrink wraps for authentication and digital tracking.
