Learn the key differences between POF (polyolefin) and PVC shrink films in terms of material, performance, safety, and application to help you find the best packaging solution for food, electronics, gifts, and more.
POF (Polyolefin) Shrink Film is made by co-extruding polypropylene (PP) and polyethylene (PE) using a double-bubble process. It offers consistent thickness, high shrinkage (up to 60%), and contains no chlorine, making it biodegradable and compliant with FDA and EU food safety standards.
PVC (Polyvinyl Chloride) Shrink Film is based on chlorinated plastic combined with plasticizers and stabilizers. It is produced using single-bubble extrusion, often resulting in thickness variations. When heated, it releases harmful gases such as hydrogen chloride, raising concerns about workplace safety and environmental impact.
POF provides excellent gloss and clarity, with uniform shrinkage that results in smooth, tight, and wrinkle-free packaging. It adapts well to products with irregular shapes, enhancing shelf presentation.
PVC has good initial clarity but tends to yellow with UV exposure or aging. During shrinkage, it can form wrinkles and seams, affecting product appearance.
POF features strong tear resistance and high flexibility. It withstands temperature variations (-50°C to 100°C) and performs well even when wrapping sharp-edged products.
PVC is more brittle, especially in cold environments. It is prone to cracking or tearing under pressure, making it less ideal for long-term or high-stress applications.
POF is odorless, non-toxic, and safe for use in food or pharmaceutical packaging. It can be recycled and meets global environmental standards.
PVC, on the other hand, releases harmful chemicals during heat sealing and is not food-safe. It is more difficult to recycle and has a higher environmental footprint.
POF has a slightly higher unit cost but lower density (approx. 0.92g/cm³ vs. 1.4g/cm³ for PVC), which can offset pricing over volume. It also reduces long-term operational costs through better machine compatibility and lower maintenance.
PVC has a lower upfront cost, making it suitable for short-term packaging needs, though hidden costs such as odor control, disposal, and regulatory compliance should be considered.
POF: Ideal for food, cosmetics, pharmaceuticals, high-end gifts, and consumer products requiring excellent clarity and safety.
PVC: More commonly used for non-food packaging such as stationery, CDs, toys, and small electronics where cost is a critical factor and regulatory requirements are minimal.
| Factor | Recommended Choice |
| Food or pharma use | POF Shrink Film |
| High-speed packaging | POF |
| Premium appearance | POF |
| Budget-sensitive needs | PVC |
POF outperforms PVC in terms of safety, durability, clarity, and environmental friendliness. While PVC may still suit some budget-sensitive applications, POF is the preferred long-term choice for businesses prioritizing product presentation and compliance.
