After years of watching the waste and damage that resulted from the use of stretch wrap on pallets in transit through his warehouse Simon Garrett of Garrett Transport in Saffron Walden decided there must be a better way for pallet packaging.
Something that was simple, protective, quick, sustainable and safe – so he invented and patented PalletSock.
Made from woven polypropylene “big bag” material the key to it’s simplicity is four panels of “powernet” elastication down each side which grips the pallet after pulling over it -like an elasticated sock.
Since the arrival of pallet hubs, of which Simons company was a founder member, he had noticed that damaged loads had risen in line with the increased handling. It is necessary for the pallet hub system to operate effectively for pallets to be handled up to 8 times on single journey. The “cuffing” of pallets during this multiple loading and unloading can tear open stretch wrap which is usually much less than 100 microns thick even after 4 wraps. PalletSock is over 5 times thicker.
Manual stretch wrapping can make you dizzy and take up to 9 minutes to wrap a pallet 4 times. Applying PalletSock takes 15 seconds. At 50 pallets per day this adds up to nearly a man day!
Currently 150000 tonnes of stretch wrap goes to landfill every year and that’s after all the recycling initiatives. In years gone by this didn’t really matter. Now we all know it does. The PalletSock is capable of at least 50 cycles before needing replacement.
If you didn’t need Stanley knives, would you allow them in your warehouse? Probably not, but there really is no alternative is there? Maybe now there is. The PalletSock doesn’t have all the answers as it obviously has a higher upfront cost than stretch wrap needs to be tracked and returned but it can be bar coded. Payback is estimated at between 6 and 15 journeys dependent upon method of wrapping and thickness of wrap.
