Explore our high-performance polyolefin, PVC, and OPP engineered films optimized for diverse industrial packaging systems.
Zhongshan Tianchen New Materials Co., Ltd. stands as a premier, integrated packaging material procurement platform built on over 20 years of manufacturing and R&D expertise within the flexible film packaging sector. Guided by market-driven engineering and resources integration, we offer globally compliant solutions configured for diverse industrial demands.
Our commitment to rigorous raw material sourcing, state-of-the-art co-extrusion technology, and advanced quality assurance protocols enables us to deliver unmatched physical properties, thermal seal strength, and aesthetic clarity across all of our film offerings.
Our dedicated team of chemical polymer experts and industrial engineers consistently refines our co-extrusion parameters. By analyzing seal thresholds, high-speed line tension parameters, and mechanical tensile dynamics, we maintain absolute uniformity in film gauges ranging from 10 to 80 microns.
Our manufacturing complex runs on automated extrusion lines, guaranteeing minimal thickness deviation and maximum compatibility with high-speed automated flow wrappers, L-sealers, and shrink tunnels.
Navigating the diverse world of flexible plastic films can be challenging. Tianchen simplifies this by providing a unified platform for OPP, BOPP, CPP, POF, PE, and PVC films. From high-barrier food packaging structures to protective industrial shrink wraps, we align material chemistry to your processing machinery.
By controlling the process from polymer blending to custom roll-slitting, printing, and micro-perforating, we reduce lead times and guarantee structural reliability.
An in-depth look at how advanced polyolefin and oriented polypropylene films solve mechanical, barrier, and optical requirements across the global supply chain.
In food packaging, managing the Moisture Vapor Transmission Rate (MVTR) and Oxygen Transmission Rate (OTR) is crucial to preserving freshness. Our custom OPP and CPP heat-seal films, enhanced with optional anti-bacterial and high-barrier coatings, help prevent moisture absorption and aerobic spoilage.
Ideal for bakery items, fresh produce, and dry food packaging, our films maintain food safety while ensuring crystal-clear shelf presentation.
Medical and personal care items require completely hygienic, dust-proof barrier protection. Our high-tenacity, low-temperature POF and high-barrier OPP films deliver robust, puncture-resistant seals at low temperatures, preserving the integrity of sensitive medical packaging.
Our processing environment adheres to strict hygienic guidelines, keeping our materials free of dust, chemical migration, and contamination.
For cosmetics, electronic boxes, and multi-pack promotions, high optical clarity (haze < 1.5%) and high gloss are essential. Our low-temperature, cross-linked POF films shrink uniformly without dog-ears or distortion, making products stand out on retail shelves.
Compatible with automated high-speed packaging lines, these films guarantee smooth running and reduce waste.
Understanding polymer chemistry is key to choosing the right film for your application. This table outlines the distinct mechanical properties of our main offerings:
| Film Type | Tensile Strength | Haze & Optical Clarity | Shrink Ratio (%) | Best Application Scenario |
|---|---|---|---|---|
| OPP / BOPP | Extremely High | Excellent (< 1.2%) | Low (< 5%) | High-speed bagging, food lamination, adhesive tapes |
| POF (Polyolefin) | High / Tear Resistant | Very Good (< 1.5%) | High (60% - 75%) | Multi-packs, retail gift wrapping, software, books |
| CPP (Cast PP) | Moderate / High Puncture | Good (< 2.5%) | Negligible | Bread packaging, retort pouches, lamination inner layers |
| PVC (Polyvinyl Cl.) | Brittle / Clean Tear | Excellent Clarity | Moderate (40% - 50%) | Wine bottle caps, CD/DVD sleeves, handmade crafts |
| PE (Polyethylene) | High Elasticity | Translucent / Milky | High MD / Low TD | Heavy beverage bottles, canned beer multipacks, pallets |

Our R&D roadmap focuses on sustainable innovation. As global markets transition toward circular economies, Tianchen is pioneering the integration of Post-Consumer Recycled (PCR) polypropylene and bio-based plastics into our film structures.
Tianchen ensures peace of mind for global buyers. Our products undergo rigorous testing to comply with international regulations, including FDA food-contact requirements, REACH, RoHS, and CE standards.

OPP (Oriented Polypropylene) is stretched in one direction, offering high clarity and good tensile strength along that axis. BOPP (Biaxially Oriented Polypropylene) is stretched both longitudinally and transversely, providing exceptional tensile strength in both directions, superior dimensional stability, and low stretchability. CPP (Cast Polypropylene) is not stretched at all during manufacturing, resulting in a film with excellent sealability, high puncture resistance, and flexibility, making it perfect for pouch liners and food bags.
Yes, all of our food-grade polyolefin (POF) and customized OPP/CPP films are made from high-purity virgin polymer resins that comply with FDA food-contact standards. We maintain a dust-free production environment and perform regular migration testing to ensure chemical safety and compliance for direct food contact.
Polypropylene has a naturally low surface energy, which makes it resistant to printing inks and adhesives. We apply a high-voltage corona discharge treatment during extrusion to oxidize the surface, increasing its dyne level to at least 38-40 dynes/cm. This ensures excellent ink adhesion for custom printing and strong bond strength during lamination.
While PVC is clear and cost-effective, it releases trace amounts of hydrogen chloride gas during sealing, which can corrode packaging machinery and create unpleasant odors. POF is an eco-friendly, odorless material that is fully recyclable. Our low-temperature POF shrink film seals at lower temperatures, reducing energy consumption and preventing heat damage to heat-sensitive products like chocolates, cosmetics, and thin plastics.
Wrinkling and dog-ears are usually caused by uneven heating or incorrect film selection. To achieve a smooth shrink, you must align the shrink tunnel's airflow and temperature settings with the film's specifications. Using micro-perforated film allows trapped air to escape quickly, ensuring a tight, uniform shrink around your product.
We provide full customization, including custom roll widths, thicknesses (from 10 to 80 microns), slip agent ratios (controlling the coefficient of friction), custom printing (up to 10-color rotogravure), hot/cold perforation patterns, anti-fog coatings, and specific shrink properties. We also offer pre-cut shrink bags to streamline manual packaging operations.
