POF Shrink Film
Polyolefin Shrink Wrap
Polyolefin (POF) shrink film is a widely used packaging material that, due to its high clarity, durability, and environmental compatibility, has become a suitable alternative to traditional shrink films like PVC. This film contracts and tightly wraps around the product when exposed to heat, creating a robust packaging. polyolefin shrink wrap is a non-toxic product ready for use in packaging hygiene products, food, pharmaceuticals, and more. The table below presents the general specifications of this film.

Types of POF Shrink Film
Standard POF Shrink Film: This is the most standard and commonly used type of POF film. It is thin, clear, environmentally friendly, and suitable for general packaging of items such as cosmetic boxes, dietary supplements, books, and dairy products.
Cross-linked POF Shrink Film: This film is enhanced through a cross-linking process, providing higher resistance and durability compared to other types. It is tear-resistant and suitable for packaging products with irregular shapes, such as balls or items that require more protection against punctures.
High-performance POF Shrink Film: This film is designed for use in fast shrink-packaging machinery. It has excellent slip features and strong sealing lines, making it suitable for products like semi-prepared noodle products.
Anti-fog POF Shrink Film: This film is specifically formulated to prevent the formation of fog or dew on the inner surface of the film. It is particularly suitable for packaging fresh food items like vegetables, fruits, meats, and frozen prepared foods that require clear product visibility. It is also useful for packaging agricultural products and preventing moisture and fog formation in them.
Polyolefin Shrink Film Properties
High Clarity and Gloss: POF films are made from high-quality polymers (usually polypropylene and polyethylene) with a regular molecular structure. This structure allows maximum light transmittance and minimizes light scattering. Additionally, the film’s surface is processed with high precision to be smooth and polished.
High Durability and Resistance: POF films are often multi-layered and reinforced through processes like cross-linking (molecular cross-linking). This process creates a tighter network of polymer chains that absorb more energy before breaking.
Uniform and Rapid Shrinkage: Polyolefin heat shrink films quickly and completely shrink when exposed to heat, creating a smooth and wrinkle-free packaging that adheres well to the product. These films can shrink by more than 75%.
Printability: POF films can be printed in up to 8 colors, allowing for branding and adding product information.
Environmental Compatibility: Polyolefin shrink wrap is made from 100% recyclable materials and has been approved by the FDA (Food and Drug Administration) for direct contact with food. This feature makes it a safe and responsible choice.
High-quality Sealing Properties: These films have excellent welding properties and can create strong and durable seals even at low temperatures, which can lead to energy savings.
Temperature Resistance: Unlike PVC, POF films are not sensitive to temperature changes; they do not become brittle at low temperatures and do not wrinkle at warm temperatures.
Variety in Thickness and Dimensions: They are produced in various thicknesses (from 10 to 50 microns) and widths (from 100 to 1500 millimeters), making them suitable for a wide range of products.
Applications of POF Shrink Film
Food and Beverage Packaging: Due to FDA approval for direct food contact, being odorless and non-toxic, and especially the presence of an “Anti-Fog” type that prevents fogging, POF is a suitable choice. Its high transparency helps showcase products like fresh fruits, vegetables, meats, and prepared meals attractively. Furthermore, its resistance to puncturing prevents food spoilage and contamination.
Toy and Game Packaging: High transparency allows for a complete view of the product without needing to open the packaging. Resistance to tearing and puncturing protects small parts and the product itself from getting lost or damaged. This feature is especially important for retail items that may be frequently handled.
Packaging of Electronic Products: POF provides good protection against dust, moisture, and scratches. This quality is vital for products that need to be kept in clean and dry conditions. Moreover, the tight and transparent packaging gives a professional appearance to the product.
Multi-item Bundling: The high tensile strength and sealing strength of POF make it very suitable for collecting and securing multiple products into one unit (such as packs of bottled water or multi-packs of tissue paper). This not only facilitates handling but also reduces packaging costs.
