Flat Sheet / Layer Pad

Flat Sheet (also called Layer Pad) is a common term in foreign trade packaging and logistics, referring to a flat sheet used for separation, support, or protection between layers of goods, typically made of corrugated cardboard, plastic hollow board, or honeycomb cardboard. Usage scenarios include: preventing cargo compression damage during layered stacking in containers, cushioning between goods on pallets, and serving as bottom/top boards for product packaging. Precautions: material (e.g., three-layer corrugated, five-layer corrugated), dimensions (length × width), thickness, and grammage must be specified to avoid disputes caused by vague specifications; if used for food or electronic products, it is also necessary to indicate whether special treatments such as moisture-proof or anti-static are required. Difference from 'Partition': a flat sheet is a whole piece of material placed horizontally, while a partition is a grid-like structure inserted vertically; difference from 'Paper Pallet': a flat sheet does not perform the function of forklift handling and only serves as an interlayer pad. In addition, flat sheets may be classified under paper product or plastic product codes during customs declaration, and must be declared according to the actual material.
