Pallet Wrap :: Need To Know

Cast Film

Machine Pallet Wrap

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 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 available.

Advantages of Cast Pallet Wrap – Less expensive than blown pallet wrap, due to reduced manufacturing costs cast is more popular. Increased clarity allows users to see wrapped products. Cast stretch wrap unwinds quietly compared to blown stretch wrap. Cast stretch film offers two-sided cling that allows the wrap to stay securely packaged.

Disadvantages of Cast Pallet Wrap – Does not offer the load/holding power blown provides. Cast stretch film has less memory and tear resistance than blown stretch film. Cast stretch film is a great general purpose wrapping solution. It is economical and covers a wide array of applications.

Blown Film

Blown Pallet Wrap

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 from an opening in the center of the die to blow up the film tube like a balloon. On top of the film tube, an air ring blows onto the film to cool it. This process allows blown to be more robust and more resilient than cast stretch film. The higher mechanical properties of blown stretch wrap typically allow a more significant load holding power.

Advantages of Blown Stretch Film – Offers higher load and stretch capacity. Blown is a premium quality film. Blown stretch wrap has a higher degree of memory once stretched, allowing product loads to stay better secured. Higher tear resistance is an advantage when securing loads with sharp edges.

Disadvantages of Blown Stretch Film – Higher cost due to the manufacturing process. The blown stretch wrap has poor clarity due to crystallization in the manufacturing process. Blown stretch wrap is also noisy when unwound from rolls.

Fusion high stretch wrap is made from high quality materials and is much stronger and can be stretched longer. This new technology reduces your use of per pallet by over 70% and is cheaper per meter. Although thinner than other stretch films, it still has the puncture resistance of a much thicker film. It is the product of the future.
