Wrapping pallets properly with machine pallet wrap to ensure your products arrive securely and safely is dependent on the type of film used and the way it has been wrapped.
There are different types of film in both hand rolls and machine rolls.
Caste Film is a nonsticky film that has better memory retention than blown film and is not sticky. It relies on the operator to stretch it rather than a gentle wrap as it relies on the retraction to give it cling. It is used on pallet wrapping machines and hand rolls. Some operators that have been used to using a sticky wrap often don’t like it to begin with as they are not used to stretching it as much as they need to. As caste film needs to be stretched it gives better pallet stability than blown film and pallets don’t stick together in delivery trucks.
Pre-Stretch is a term used for a higher performance caste film that is used on pallet wrappers that have a power pre-stretch unit fitted. The power pre-stretch unit stretches the film by 300 – 400% before applying it to the pallet. It is normally used in higher volumes.
Pre-Stretched (E-Stretch) film is a caste film that has been stretched before it is wound onto the cardboard core. This means that the operator can apply the film with very little stretch and the film contracts after it’s been applied to the pallet giving good pallet stability. It is used in hand rolls and on machines. It is a good machine film for lightweight pallets as you can apply it with very low tension and achieve a high tension result.
Nanofilm is a multi-layer machine pallet wrap that is very strong and very thin. It is used on power pre-stretch pallet wrappers as it a very high-performance film. With nanofilm, your cost per wrapped pallet will be less and the amount of film used will be less, reducing your carbon footprint, and the pallet stability is exceptionally good.
