Which Pallet Wrap Should I Use?

What’s the best pallet wrap?

Choosing the best type of pallet wrap for your application is important. There are a few things to consider depending on the type of pallet wrapper you use and the type of product you are wrapping

Which Pallet Wrap Should I Use?

When deciding which pallet wrap is best to use there are a few things you will need to consider. The first would be to look at the wrapping machine you are using.

Does the wrapper have a powered pre-stretch unit built into the film carriage? 

Power-Pre-Stretch

A powered pre-stretch unit in the film carriage is a unit with two rollers that are driven by a motor at different speeds to stretch the film. Different machines stretch at different ratios. A popular ratio will stretch the film at 250%. Some machines will stretch up to 400% and these are for use with high-performance films.

If your pallet wrapper does not have a power pre-stretch unit then it will have a core brake. 

Core-Brake

A core brake is either a manual or an electronically controlled brake that slows down the rotation on the film carriage to give tension to the film as it is being pulled off the roll by the motion of the pallet on the turntable. 

For core brake machines you would use a standard pallet wrap or a pre-stretched pallet wrap. A pre-stretched pallet wrap is a film that has been stretched before it has been reeled onto the cardboard core. The advantage of using this type of film is that you can apply the film to your pallet at very low tension. The plastic retention memory will trigger, and the film will contract after it has been applied. This is particularly good for light loads.

Traditionally there have been two types of film in 20 or 23micron thicknesses. A standard film for core brake machines and a Pre-Stretch film for power pre-stretch machines. These are still very popular films and whilst pallet wrap is recyclable there has been a drive over the last few years to reduce the amount of packaging waste.

Reducing the amount of packaging waste has been achieved by altering the manufacturing process and producing a multilayer film. By altering the material composition of the individual layers, it has been possible to produce a film that has an overall thickness of just 11 microns with a greater puncture resistance than traditional films and can be stretched up to 400%.

Standard Film

Standard film is one of the original types of pallet wrap for pallet wrappers that have a core brake tension system. This type of film has a stretch ratio, or elongation, of around 150% and typically would be used on light to medium weight pallets.

Standard film is manufactured in 20mu and 23 mu thicknesses.

Pre-Stretched Film

Pre-stretch film is a type of stretch wrap film that has been stretched near its breaking point before being wound onto its cardboard core. The pallet wrap is typically pre-stretched to around 90%, which is why pre-stretched film is thinner than most other pallet wraps.

With this type of film you can apply to the pallet at a lower tension. The plastic memory retention kicks in after it’s been wrapped and the film contracts around the pallet to secure the load.

Power Pre-Stretch Film

Power Pre-Stretch film is a film that will stretch 250 – 400% and is used on pallet wrappers that have a power pre-stretch unit in the film carriage.

Multi-Layer Film

Multilayer film has been designed as a direct replacement for the standard and power pre-stretch film to increase performance and reduce the amount of packaging waste. By altering the composition of the individual film layers is has been possible to create a 12mu film that outperforms a standard film and as it is a lot thinner the amount of film used per wrapped pallet is less.

In addition to saving in packaging waste, there is also a cost-saving as the cost per wrapped pallet is also less.

There are two different film specs. One to replace standard film and another to replace power pre-stretch film.

PRE-STRETCH SYSTEM = ECONOMIC ADVANTAGE

All models of SPINNY S300 are equipped with a high-performance MOTORIZED PRE-STRETCH SYSTEM. The power pre-stretch is a special device that allows the best utilization of the stretch film quantity: moreover, it permits to wrap light and unsteady pallets that couldn’t be wrapped with different friction systems. The stretch film is supplied in the right quantity by the rollers that are operated by a motor, which is controlled by an electronic system that measures the speed and keeps the film tension constant on the whole pallet’s surface. The motorized pre-stretch system allows the efficiency of the film up to 300%.

DUAL MOTOR

The DUAL MOTOR version is designed to let you save even more film, obtaining more economic advantages. Based on the same principle of the single motor version, the DUAL MOTOR system offers variable stretch factor up to 400%!
