Zhongshan Tianchen New Materials Co., Ltd. is a premier one-stop packaging material procurement platform established on the foundation of more than 20 years of hands-on expertise in the film packaging industry. Our company is built on a legacy of integrated resources and client-first engineering, ensuring that we design and deliver advanced polymer products customized for global industrial supply chains. By matching rigorous testing frameworks with large-scale production capabilities, Tianchen bridges the gap between high-volume manufacturing requirements and strict regulatory tolerances.
We believe that packaging film is not merely a consumable; it is a critical component of product integrity, brand communication, and supply chain performance. Our modern quality control system monitors every phase of extrusion, cross-linking, perforation, and printing to guarantee exceptional performance across varying heat-tunnel configurations and high-speed automatic wrapping lines.
For modern engineering and procurement specialists, selecting a packaging material requires a rigorous analysis of physical, chemical, and thermal properties. Modern shrink films rely on structured polymer chains that have been oriented during the extrusion phase and are designed to relax back to their unoriented state when exposed to thermal energy. The three core materials dominating this sector are Polyolefin (POF), Polyethylene (PE), and Polyvinyl Chloride (PVC).
POF is a co-extruded copolymer material consisting of multiple layers, typically alternating between Linear Low-Density Polyethylene (LLDPE) and Polypropylene (PP). This layout provides exceptional tensile strength, absolute clarity, and superior puncture resistance. Because it is completely cross-linked and chemically inert, POF does not release volatile organic compounds (VOCs) or corrosive hydrochloric gas when exposed to high heat tunnels. This makes it the standard choice for food-grade, cosmetics, and luxury consumer goods packaging.
PE is a high-density, high-durability polymer utilized for grouping, heavy duty bundlings, and large format logistics. Primarily processed as Low-Density Polyethylene (LDPE) or Linear Low-Density Polyethylene (LLDPE), this film provides the thick gauge (ranging from 30 to over 150 microns) needed to secure heavy industrial components, beverage multipacks (cans and bottles), and pallet units. PE relies on high elasticity and strong seal-strength to replace corrugated boxes, decreasing total cargo weight and shipping volumes.
PVC continues to be a staple material for custom label sleeves, high-gloss retail products, and adhesive tape wrapping due to its exceptional dimensional stability, high shrink rate at lower temperature thresholds, and superior clarity. It shrinks uniformly in both machine direction (MD) and transverse direction (TD), preventing distorted graphics on asymmetrical containers.

Adapting polymer configurations to meet the specific requirements of various demanding industries.
Food contact packaging demands absolute material purity. Our POF shrink films are manufactured under strict sanitary conditions to prevent contamination. Our breathable perforated films prevent moisture buildup in fresh produce, keeping products fresh throughout the supply chain. For heavy carbonated drinks and water bottles, our high-density PE shrink films offer the high puncture resistance needed for stable multipack packaging without the need for secondary cardboard packaging.
Heavy parts, machinery components, and automotive spares require robust protective packaging to withstand environmental exposure. We manufacture thick-gauge PE shrink films and specialized POF automotive protection sheets that safeguard components from dust, moisture, and micro-scratches. These films feature high tear propagation resistance, maintaining structural integrity even if punctured during transit.
Shelf appeal is critical in retail environments. Our high-clarity PVC and POF films feature low haze and high gloss properties, making colors pop on packaging. The print-treated surfaces allow high-speed UV flexographic and gravure printing, turning protective sleeves into high-impact marketing surfaces that shrink uniformly around custom-shaped bottles without distorted graphics.
Navigating customs, safety standards, and regional certifications to guarantee frictionless international procurement.
Sourcing raw materials from China requires absolute compliance with regional regulations. Tianchen works alongside global testing agencies to keep all product lines fully certified:
To mitigate shipping risks, our packaging materials are wrapped in moisture-resistant vapor barrier foil and secured on export-grade pallets. This keeps the shrink films safe from high humidity and extreme temperatures inside sea containers, preventing premature shrinkage during ocean transit.
Detailed insights from our material engineers to address common questions from procurement managers and packaging line operators.
POF (Polyolefin) is a multi-layer, recyclable copolymer film that does not emit toxic fumes during heat sealing. It offers high clarity, high puncture resistance, and stays flexible at low temperatures. PVC (Polyvinyl Chloride), on the other hand, shrinks at lower temperature thresholds and offers excellent flat lay properties. However, it releases minor amounts of HCl gas during sealing, which requires machinery maintenance and proper ventilation. Additionally, PVC is less widely accepted in modern municipal recycling programs than POF.
The shrink percentage of PE film is determined by three variables: the tunnel temperature curve, the exposure time, and the volume of air circulation. If the tunnel temperature is too low, the oriented polymer molecules will not relax completely, leading to loose packaging. If the temperature is too high, it can melt the seals or weaken the film's structural integrity. Testing and adjusting these settings is key to achieving optimal shrinkage.
Cross-linking connects individual polymer chains through electron-beam irradiation, forming a strong three-dimensional network. This enhances the film's tensile strength, seal durability, and puncture resistance. It also prevents the film from tearing on sharp corners or heavy loads, making it ideal for shipping heavy, irregular-shaped items.
We recommend storing all shrink film rolls in climate-controlled environments with temperatures kept below 30°C (86°F) and relative humidity below 60%. Direct exposure to sunlight or heat sources can trigger pre-shrinkage, which can deform the rolls and affect their performance on packaging machines.
