Industrial-grade POF, PVC, and CPP/OPP co-extrusion films engineered for high-speed automated packaging lines and robust protection requirements.
Zhongshan Tianchen New Materials Co., Ltd. – Your One-Stop Packaging Material Procurement Platform.
Established on the foundation of more than 20 years of intensive experience in the film packaging industry, Tianchen acts as a comprehensive, highly integrated one-stop packaging material procurement platform. Driven by a commitment to supply chain resource optimization and addressing the high-performance demands of global B2B buyers, we ensure that our customers receive precise technical solutions tailored for their diverse packaging lines.
Our dedicated laboratory engineers continuous improvements in resin formulations, thermal shrink capabilities, and high-clarity barrier properties.
With an advanced inline thickness gauge system and ISO-compliant procedures, every single batch meets rigorous thickness and seal strength tolerances.
Ensuring end-to-end efficiency, safety, and performance for packaging converters and direct brand enterprises.
At Tianchen, quality control is woven into every phase of our manufacturing process. Our experienced production, research & development, and sales teams execute strict verification workflows. A modern QC system monitors mechanical attributes such as Coefficient of Friction (COF), haze values, tensile strength, and heat-seal windows. Our heavy investment in state-of-the-art co-extrusion technology enables us to deliver custom-formulated films that consistently align with our buyers' high standards.
Navigating the diverse world of flexible plastic films can be challenging. By integrating top-tier manufacturing lines with custom conversion facilities, Zhongshan Tianchen New Materials Co., Ltd. serves as a comprehensive, direct sourcing partner. Whether you require custom heat-sealable CPP films for vertical form-fill-seal (VFFS) systems, high-clear POF shrink wraps, or heavy-duty printed PVC sleeve materials, our team handles the engineering, logistics, and quality assurance under one roof.
Cast Polypropylene (CPP) film has emerged as a cornerstone of modern flexible packaging. Unlike Biaxially Oriented Polypropylene (BOPP), CPP is produced via a non-oriented cast extrusion process. This provides the polymer chain with distinct physical advantages: exceptional seal integrity, high puncture resistance, good optics, and reliable high-temperature tolerance. In the packaging hierarchy, custom CPP serves primarily as the critical heat-sealing layer in multi-layer laminates, protecting food, pharmaceuticals, and consumer goods from contamination and mechanical failure.
Modern packaging conversion demands exact control over film performance. To achieve this, our factories utilize multi-layer co-extrusion technology (primarily 3-layer and 5-layer structures). This allows our engineers to isolate distinct polymer attributes across different layers:
Understanding the mechanical properties of different materials is key to specifying the correct film for your application. The table below outlines the primary comparative metrics for CPP, BOPP, and PE films:
| Property / Metric | Cast Polypropylene (CPP) | Biaxially Oriented PP (BOPP) | Polyethylene (PE) |
|---|---|---|---|
| Sealing Strength | Excellent (> 15 N/15mm) | Poor (Requires Sealant Coatings) | Very Good (> 12 N/15mm) |
| Puncture Resistance | High (Ideal for sharp foods) | Moderate | Excellent |
| Optical Haze | Low (1.5% - 2.5% for high-clear) | Very Low (< 1.0%) | Moderate (4.0% - 8.0%) |
| Thermal Stability | Excellent (Up to 135°C Retort) | Moderate (Prone to shrinkage) | Low (Melts at 105°C - 115°C) |
| WVTR (g/m²/24h) | Low (4.0 - 6.0) | Very Low (2.5 - 4.0) | Low (5.0 - 7.0) |
Our custom CPP film lines are engineered to address specific requirements in several major global industries:
The flexible packaging sector is actively transitioning toward circular economy models. Tianchen is currently investing in two key development areas:
How we integrate advanced technologies to achieve reliable manufacturing, lower costs, and responsive lead times.
Our raw material handling systems use loss-in-weight gravimetric dosing. This allows us to feed precise ratios of PP resin, anti-slip agents, antiblock additives, and antistatic masterbatches with less than 0.1% variance.
Integrated automatic dies connect directly to NDC scanners. This real-time thermal bolt adjustment system automatically corrects gauge deviations across the web, ensuring excellent roll flatness and preventing telescoping.
Located in Zhongshan, Guangdong, our factory sits in a key industrial logistics hub. We utilize direct shipping networks out of Nansha, Yantian, and Shekou, allowing us to deliver orders to the port in under 24 hours.
