POF shrink film, also known as polyolefin shrink film, is a multi-layer co-extruded packaging material widely used for wrapping and protecting products. Unlike PVC shrink film, POF is free from chlorine and heavy metals, making it a more environmentally friendly choice. It offers excellent clarity, uniform shrinkage, and good toughness, ideal for both automatic and manual packaging lines.

POF shrink film is commonly supplied in center-folded form, which is convenient for automatic packaging machines. When heated, the film shrinks tightly around the product, creating a clear, tamper-evident wrap. It is widely used in food, cosmetics, stationery, daily chemicals, and electronic accessories. For food items like bread, pastries, and snacks, POF film provides moisture protection and extends shelf life. For cosmetics and skincare sets, it enhances shelf appeal and protects against dust and humidity. Daily necessities such as shampoo bottles, body wash, and kitchen items also benefit from its clarity and strength.

Key technical parameters of POF shrink film include:

• Thickness: 12–30 μm, with common values of 15, 19, and 25 μm.

• Shrinkage: ≥ 55% (MD) and ≥ 60% (TD) at 120°C for 30 seconds.

• Tensile strength: ≥ 90 MPa (MD) and ≥ 100 MPa (TD).

• Elongation at break: ≥ 350% (MD) and ≥ 400% (TD).

• Light transmittance: ≥ 89%, haze ≤ 3.5%.

• Heat seal strength: ≥ 4.5 N/15mm.

• Density: 0.91–0.93 g/cm³.

These values are tested according to international standards such as ISO 527-3 for tensile properties, ASTM D2732 for shrinkage, ASTM D1003 for optical properties, and ASTM F88 for heat seal strength.

POF shrink film is available in various widths and roll lengths. Common folded widths range from 150 mm to 900 mm, and roll lengths from 800 m to 5,000 m. Custom sizes are available upon request. The film can also be printed with brand logos or patterns for enhanced branding.
