Top sheet is a thin Polyethylene film applied to the top of a pallet mostly in conjunction with stretch film and warp to totally encapsulate pallet contents. Also, these covers can be placed under items that will be placed directly on ground or stacked on top of others. Advantages: • Economical advantage: Polyethylene top sheet is much more economical than corrugated top caps. • Dust protection: the top sheet cover protect the packed products from dust, dirt and other elements that may affect the look or damage the product during transit and storage. • Moisture/Water protection: Top cover sheet provides moisture protection and a level of water resistance. To have a water protection, stretch film on side should be applied first, and then top sheet should be applied and then locked into place by another stretch film layer. Appling top sheet first then locking in place with stretch film will provide moisture protection only.
