Westside Packaging MAXI performance machine grade stretch films provide both high strength and high stretch. They’re specially manufactured to stretch up to 250%, depending on the gauge. This enables more pallet loads per roll to be wrapped, using less film, resulting in the lowest cost per load.

With high performance film, the more it is stretched, the more the film recovers to hold loads tight and prevent product damage. Genuine 15kg rolls plus core.

Blown Films

Blown stretch film (wrap) is manufactured using the blown extrusion process. This Plastic melt is extruded through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the centre of the die to blow up the tube like a balloon. On top of the tube an air ring blows onto the film to cool it. This process allows blown film to be tougher and more resilient than cast film. The higher mechanical properties of blown film typically allow a greater load holding power.

Blown stretch film provides greater tear resistance, tension retention and scuff resistance than cast film, making it ideal for heavy industrial loads, irregular loads and loads with sharp corners.

Cast Films

Cast stretch film (wrap), is manufactured using a cast extrusion process. The Cast extrusion process is a continuous process by which a thermoplastic material is melted and extruded through a flat die onto a chill roll, where it is quenched and re-solidified. This process allows the Cast stretch film to have excellent clarity, require less force to stretch, increased tear resistance, unwind quietly from machines, and offer a superior cling.

There are both machine grade and hand grade cast stretch film available.

Cast film provides better clarity and gloss, and quieter film unwind than blown films. These characteristics make cast film a good choice for cube shaped loads, and loads that are used for display purposes.

Cast and blown films are available for machine and hand use, coloured and black films also available.
