Pallet Top Sheets Pallet top sheets are designed to protect stretch-wrapped pallets from wet weather and dust during transit and in storage. A warehouse essential, these tough-wearing sheets are supplied on a perforated roll for easy separation and handling. To apply the polythene sheet, simply pull the stretch film to the top of the pallet, lay the sheet over, then add a further layer of stretch film, securing the polythene between the layers. All pallet top sheets are supplied centre folded. The dimensions displayed show the width of the sheet opened out.
