Performance Advantages and Characteristics of POF Heat Shrink Film

POF heat shrink film, the full name of which is multilayer co-extruded polyolefin heat shrink film, is a new type of environmentally friendly shrink film.

The following is a detailed introduction:

Features

High transparency and gloss: POF heat shrink film has excellent transparency and gloss, clearly showing the appearance of the product, enhancing the visual appeal of the product, and enhancing the product's competitiveness in the market.

Good shrinkage performance: Its shrinkage rate is large, up to 75%, and the shrinkage force is controllable. It can tightly wrap products of various shapes and sizes, whether regular or irregular shapes, achieving perfect packaging effects.

High toughness and tear resistance: The product has a tight molecular structure, with high tensile strength and tear resistance. It is soft in texture but tough and durable. During packaging, transportation, and storage, it can effectively protect products from external factors such as collisions and friction, and is not easy to crack or damage.

Excellent heat sealing performance: POF heat shrink film has good heat sealing performance, a wide heat sealing range, good low-temperature weldability, a firm seal that is not easy to crack, and is suitable for manual, semi-automatic, and high-speed fully automatic packaging equipment. It can meet the needs of different packaging production lines, improving packaging efficiency and quality.

Good cold resistance: Even at low temperatures of -50°C, POF heat shrink film remains soft and does not become brittle. This makes it ideal for packaging products that need to be stored and transported in cold environments, such as frozen food.

Environmentally friendly and non-toxic: POF heat shrink film is made from environmentally friendly materials and does not produce toxic gases or odors during processing and product application. The product's hygiene performance meets US FDA and USDA standards and can be directly used to package food, pharmaceuticals, and other products with high hygiene requirements.

Good moisture resistance and barrier properties: Due to the unique oxygen barrier layer produced by the three-layer composite, it is airtight and moisture-proof, has good barrier properties, and is not easily contaminated by dust. It can effectively prevent products from getting damp, oxidizing, and being damaged by other pollutants, extending the shelf life of the products.
