The pallet must be lifted so that all four of its corners are free: the aim of this is to allow the film to shrink under the pallet and to thus produce great cohesion between the pallet and the load it supports.
The Calpack pallet raiser is the perfect accessory to facilitate this operation.
You simply need to then slide the shrink cover onto your pallet, and leave enough length to be able to shrink underneath the pallet (H + 200 mm).
RECOMMENDATIONS FOR SHRINK WRAPPING (in the absence of specific instructions from the film manufacturer):
Remain at a minimum distance of around 30 centimetres from the film and begin wrapping with the lowest part of the four sides, so that the wrapping starts underneath the pallet. Remember to direct the hot air flow perpendicularly along the sides of the pallet.
Apply heat with a continuous movement, at a steady speed.
As the reactions of various films will not necessarily be the same, monitor closely and modify the heat speed and/or your distance from the film accordingly.
You can also modify the power of your Ripack heat shrink gun thanks to its adjustable Securipack pressure reducer.
Once the bottom of the pallet is shrink wrapped, perform the same operation for each side, working your way around the full width of each side, from bottom to top.
Once the four sides are completed, wrap the top by directing the hot air flow onto the top of the pallet.
Please use our video tutorials in order to understand the logic of the film’s shrink wrapping process.
Due to its constitution, shrink film continues to shrink after heat application, for a variable time period, which depends on its quality, its thickness and the type of load wrapped. It is therefore recommended to wait for the wrap to be cooled and taut before moving.
After cooling and before storage, always check the integrity of the shrink wrap and the products packaged.
