Browse our premium, engineered polymer thin-films designed for durability, clarity, and precision-engineered shrinkage rates.
Your One-Stop Packaging Material Procurement Platform built upon two decades of engineering excellence.
Zhongshan Tianchen New Materials Co., Ltd. is a comprehensive packaging material platform established on the foundation of over 20 years of experience in the polymer film manufacturing sector. Guided by market evolution and custom material requests, Tianchen has integrated extensive supply chain capabilities with leading R&D standards. This continuous evolution has made us a leading global choice for brands searching for reliable shrink wrap, barrier film, and high-tenacity packaging films.
Our dedication lies in simplifying the procurement flow while raising the structural threshold of custom packaging. From highly specific low-temperature POF shrinkages to medical-grade, antibacterial CPP & OPP composite barrier films, we focus on technical accuracy. We deliver consistent barrier performance, high tensile index strength, and unmatched clarity across every batch.
At Tianchen, we run an advanced QC laboratory paired with our expert product engineering departments. Quality management isn't just an inspection phase; it is embedded throughout our entire extrusion, cooling, and slitting process. We verify density tolerances, seal-strength integrity, and surface treatment values (Dyne levels) systematically to ensure high stability on modern, high-speed wrapping equipment.
With over twenty years of material refinement, we have optimized our supply chains. This enables Custom Materials Group to offer a complete catalog of film grades. Whether you need standard PVC cap seals or high-performance cross-linked food-safe barrier POF films, we handle everything from formulation to final delivery. This streamlined structure helps our partners save on logistics and lower their total cost of ownership.
An analytical look at polymer architectures, cross-linking processes, and barrier technologies that define our product quality.
Standard POF utilizes basic layered structures. In contrast, our cross-linked POF shrink film undergoes an electron-beam irradiation process. This technique binds polymer molecules into a dense, three-dimensional network. As a result, the film achieves outstanding puncture resistance, strong seal integrity, and high tear propagation limits. These properties make it ideal for high-speed machinery and packaging odd-shaped items.
Our Cast Polypropylene (CPP) and Oriented Polypropylene (OPP) films use a multi-layer co-extrusion process. We formulate specific layers to optimize low hot-tack sealing temperatures, high tensile strength, and robust barrier characteristics. Incorporating food-grade antibacterial compounds helps inhibit microbe growth, extending the shelf-life of fresh produce and retail goods.
Perforation pattern control is vital for packing living organisms or moisture-sensitive foodstuffs (such as eggs or warm baked goods). Our hot-needle perforation process melts the edges of each microscopic vent hole. This prevents tearing under tension while allowing targeted gas and vapor exchange.
| Film Type / Technical Indicator | Shrink Temp Range | Haze Level (%) | Tensile Strength (MPa) | Sealing Strength | Primary Application |
|---|---|---|---|---|---|
| Cross-Linked POF Film | 110°C - 160°C | < 1.5% | ≥ 100 MPa | Ultra-High | Heavy-duty retail, irregular shapes |
| Standard PVC Film | 80°C - 130°C | < 2.5% | ≥ 45 MPa | Moderate | Wine caps, batteries, light retail |
| Low-Temp POF Film | 90°C - 120°C | < 1.8% | ≥ 80 MPa | High | Heat-sensitive items, cosmetics |
| CPP Barrier Film | Non-Shrink (Sealable) | < 3.0% | ≥ 30 MPa | Excellent (Heat Seal) | Antibacterial food packaging bags |
Why global brands choose Zhongshan Tianchen New Materials as their primary manufacturer.
Our facilities are located in Zhongshan, Guangdong, the heart of China’s high-tech manufacturing corridor. This location connects us to advanced polymer resin supplies, domestic transport links, and nearby major export ports like Shenzhen and Guangzhou.
We operate multi-layer co-extrusion blowing lines with continuous thickness-monitoring scanners. These computerized systems automatically adjust the die gaps, keeping film thickness variations within ±3%, which prevents thin spots during high-ratio stretching.
By combining large-scale raw material procurement with optimized energy consumption systems, we pass the savings directly to our buyers. This allows global brands to access high-performance films at competitive factory prices.
Customized film designs engineered to meet the unique challenges of major industrial sectors worldwide.
Food preservation requires strict moisture control and barrier properties. Our breathable, hot-perforated POF films let fresh produce "breathe," reducing condensation build-up and decay. For meats and dairy, our high-barrier antibacterial CPP and OPP films seal out pathogens, extending shelf-life and ensuring safety.
The wine and spirits industry relies on visual appeal and security. Our PVC shrink caps fit tightly around bottle closures, protecting against tampering. These caps shrink rapidly under hot air or steam tunnels without damaging the underlying cork or glass neck.
Metal parts and assemblies need protection from abrasion, moisture, and dust during storage and transport. Our thick, heavy-duty POF automotive films provide high puncture resistance and strong holding force, keeping items secure during sea transport.
Navigating environmental demands, smart packaging integration, and strict regulatory standards.
The global packaging industry is moving toward circular solutions. Companies face increasing pressure to lower carbon emissions and choose recyclable materials. At Custom Materials Group, we are leading this change by focusing on ultra-thin film downsizing and developing polyolefin formulations that can be recycled alongside standard LDPE streams.
Downgrading our film thickness while keeping high mechanical strength helps logistics companies reduce their plastic weight footprint. This directly helps brands lower their plastic taxes and carbon offsets in regions like the European Union and North America.
Our raw materials are fully compliant with major global standards, including FDA food-contact regulations, EU REACH directives, and RoHS limits. We implement strict batch control systems, allowing you to trace each finished roll back to its original polymer resin lot. This complete transparency ensures peace of mind for food, pharmaceutical, and high-value consumer electronics manufacturers.
