Handling and Storage:
1. Poly sheets should be transported and stored horizontally, on a flat, sturdy pallet whose dimensions are equal to or larger than the sheets themselves. The sheets must be secured and fastened to the pallet during transportation and handling on site. It is possible to stack the sheets with the longer sheets at the bottom and the shorter on top, leaving no unsupported overhang.
2. Void leaving the sheet pallet in the rain, even if still wrapped, for extended periods, as water may condense inside the hallow core. Extended exposure to direct sunlight may cause heat build up, softening the protective film, fusing it to the sheet face, making removal difficult or impossible.
3. Avoid leaving the sheets stored unwrapped, with their ends open, for more than a few days, as dust may collect inside the hallows.
4. Important! Never cover the pallet with, or place on the pallet, materials that collect heat or are good heat conductors (e.g dark objects, metal profiles or pipes, steel sheets etc.) They may collect and deliver excess heat, and damage the sheets.
5. When necessary to store he pallet in the open, cover it with a white opaque polyethylene sheet, cardboard, or any other insulating material, taking care to cover the pallet completely.
