Optimising Pallet Wrapping Machines
How do you do it?
This depends on the machine, however the over riding principle is the same. First you need to understand the properties and capabilities of the film that is being used, then you need to ensure that the machinery is set to maximise the films performance and output. In most instances, pallet wrap machines are Power Pre Stretch (PPS), meaning that the machine film is stretched in the machine stretch head by rollers turning at different speeds, before it is applied to the pallet. Occasionally, the ratio of this stretching ability can be adjusted automatically, but in most instances this is dictated by gears attached to the rollers. Understanding the ability of the film and matching it to the gearing of the rollers is the single most important aspect of the optimisation process.
The next thing to ensure is that the stretch rollers on the machine are undamaged and clean. Some manufacturers rollers are very susceptible to damage from operators trying to remove snapped film from the roller using a knife – you can read an article that we have written on this by clicking the link below.
Assuming the rollers are undamaged, a simple clean down using an industrial wipe or clean microfibre cloth and water will produce significant improvements.
Next, pay attention to the wrap cycle, is the pallet being wrapped with optimum overlap between film layers? Is the film locking to the pallet base? Is the holding force optimised at all levels of the pallet? This is a technical assessment and you will probably need the support of a load stability expert using calibrated load stability testing equipment. At Hazel 4D, using or testing kit, we can provide clear reporting on the load holding force.
