​Cast and Blown Pallet Stretch Wrap

There are two different types of stretch wrap: blown stretch wrap and cast stretch wrap. These two types have their similarities, but there are also many differences between them. This includes the way that they are manufactured, their application use, and more. It is important to choose the right kind of stretch wrap for your secondary packaging needs. If you use the wrong type of film for your load, it could lead to product loss or damage during freight shipment, along with other issues, such as difficulties reading or scanning. two.

Which One Is Better? Neither type of stretch wrap is inherently better than the other. They are simply better suited for different purposes. You can compare these two types of stretch wrap in seven categories: load retention, film memory, film yield, puncture resistance, cling, visual clarity, and noise of unwind. Understanding the differences between cast and blown stretch wrap when it comes to these seven factors is the easiest way to determine which type of stretch wrap is the best option for a specific load.

Load Retention: If you want less stretch, blown film is the better choice. Even after being applied to the pallet, cast film will stretch easily.

Film Memory: Blown film has much better film memory, which means it can shrink back after stretching. Cast film will have a much harder time returning to its original state.

Film Yield: Cast film will stretch much further than blown film, which will allow you to cover more pallets with less film.

Picture Resistance: Blown film is much more resistant to breaking, although cast film will normally only tear when put under great amounts of stress.

Cling: Blown film is only clingy on one side. Cast film is naturally clingy on both sides, which can cause pallets to stick together.

Visual Clarity: Since blown film is not completely translucent, it can make reading and scanning more difficult. It does, however, have a lower gloss that can reduce reflections. If you want something that is clear, go with cast film—just keep in mind that it has higher gloss.

Noise of Unwind: If you want some peace and quiet, opt for cast film, which is silent when it is being unwound from the stretch roll. Blown film, on the other hand, tends to be loud.
