Engineered for high-speed automated packaging machinery and rigorous industrial environments. Designed to operate flawlessly in Rajshahi's manufacturing zones.
Rajshahi, traditionally recognized as the agricultural capital of Bangladesh, is transitioning rapidly into a diversified manufacturing and agro-processing powerhouse. With the growth of modern food processing facilities, beverage factories, and regional distribution centers, the demand for superior packaging materials has reached critical levels.
Polyolefin (POF) Shrink Film has emerged as the definitive standard for local businesses aiming to align with global trade compliance. Compared to obsolete PVC materials, POF provides exceptional clarity, high tear resistance, and eco-friendly composition, which are vital for export markets in Europe and North America.
Our POF Shrink Film is manufactured using state-of-the-art 5-layer co-extrusion technology, providing precise mechanical values required by automated packing lines.

In a competitive marketplace, Zhongshan Tianchen New Materials Co., Ltd. stands out as a reliable partner for all your packaging material needs. As a one-stop packaging material procurement platform, Tianchen combines decades of industry expertise with a passion for quality and customer satisfaction. Whether you need eco-friendly heat shrink films or durable labeling solutions, Tianchen is here to provide the best in the industry.
Modern POF formulation has advanced from basic raw PE/PP blends to sophisticated co-polymers customized for functional applications. Our team continues to optimize molecular structures to improve packaging efficiency and minimize mechanical failure during distribution.
By employing high-energy electron beam irradiation post-extrusion, polymers in the film cross-link at a molecular level. This converts linear chains into a multidimensional mesh. For Rajshahi manufacturers packing heavy-duty mechanical items or sharp-edged containers, this process improves tear propagation resistance by up to 100% and prevents zipper-splitting on high-tension L-bar sealers.
For fresh poultry, eggs, and local agricultural produce like Rajshahi mangoes, packaging breathability is critical to prevent moisture condensation and mold growth. Our hot perforation technology introduces micro-apertures without compromising the structural integrity of the film web. This breathability extends product freshness, supporting exporters who ship goods over long domestic and international logistics routes.
Sustainability is no longer optional in international commerce. Modern global brand owners demand films containing Post-Consumer Recycled (PCR) materials. Our current development focuses on incorporating up to 30% chemical-grade PCR into the core layers of our films, offering an eco-friendly option that meets safety standards for direct food contact.

For industrial buyers in Rajshahi, import logistics, customs clearance, and quality assurance are critical factors when sourcing packaging materials. As a global supply partner, we provide end-to-end logistics solutions, ensuring stable raw material supply regardless of seasonal shifts.
Review the technical answers compiled by our application engineers regarding POF shrink film performance, machine settings, and storage conditions.
Polyolefin (POF) is highly durable, retains soft flexibility post-shrinkage, and is fully recyclable without emitting toxic odors during sealing. PVC shrink film, while simple to process at lower temperatures, tends to become brittle over time and releases trace chlorine gas during heat-sealing, which can corrode equipment and pose health concerns in food-packaging facilities.
Cross-linked POF film requires slightly higher sealing temperatures (typically 140°C to 175°C depending on machine speed) but offers a broader operating window. Its high mechanical strength prevents the seal line from thinning or breaking, even under high shrink-tunnel velocities.
Our hot-perforation tooling creates micro-perforations during the winding process. These tiny vents allow moisture from fresh foods, eggs, or produce to escape, preventing steam buildup within the sealed pack. This mechanism helps control moisture and extends shelf-life in humid climates.
To prevent natural pre-shrinkage or blocking (where layers stick together), POF rolls should be stored in a dry, ventilated warehouse below 30°C. Keep rolls vertical inside original packaging until production, avoiding direct sunlight and proximity to heating ducts.
