Partition paper, also called interleaving paper or slip sheet, is a thin protective sheet placed between stacked products to keep their surfaces from touching. By separating one item from the next, it prevents scratches, abrasion, friction marks, and contamination while goods are stacked, stored, and shipped. It is a simple, low-cost layer that quietly protects high-value surfaces such as glass, polished metal, and circuit boards, and it is widely chosen over foam or plastic because it is lighter, cheaper, and recyclable.<\/p>\n\n\n\n
When identical items are stacked directly on each other, the tiny movements that happen during handling and transport cause the surfaces to rub. On a polished, coated, or finished surface, that rubbing creates scratches and marks that can ruin the part. A sheet of partition paper<\/a> between each layer breaks that contact. Its smooth, non-abrasive surface lets items slide apart cleanly and absorbs friction instead of passing it to the product.<\/p>\n\n\n\n Good partition paper does its job without becoming a new source of damage. That means a clean, low-impurity surface, a controlled neutral pH so it does not stain or tarnish the product, and consistent fiber quality so it sheds little dust. For sensitive metals, sulfur-free grades prevent the tarnish that ordinary paper<\/a> can cause. These are the properties that separate true industrial interleaving from generic packing paper.<\/p>\n\n\n\n Partition paper is used wherever surface quality matters during stacking and transit:<\/p>\n\n\n\n \u2022<\/strong> Glass and displays:<\/strong> interleaving sheets between glass panels, mirrors, and display glass prevent abrasion, edge chipping, and staining, and keep sheets from sliding in automated lines.<\/p>\n\n\n\n \u2022<\/strong> Metals and steel:<\/strong> sheets placed between stainless or cold-rolled steel sheets and coils prevent friction marks and protect the finish, with neutral-pH grades avoiding ion staining.<\/p>\n\n\n\n \u2022<\/strong> Electronics and PCB:<\/strong> clean, low-contaminant interleaving protects circuit boards and components from scratches and particles.<\/p>\n\n\n\n \u2022<\/strong> Precious metals:<\/strong> sulfur-free interleaving keeps silver and other reactive metals from tarnishing in storage.<\/p>\n\n\n\n Because it is thin and recyclable, partition paper also helps reduce package weight and material cost compared with foam inserts, while still delivering reliable surface protection. It is supplied as sheets or rolls in custom<\/a> sizes.<\/p>\n\n\n\n We manufacture partition and interleaving paper to your specification.

It prevents scratches, friction marks, and contamination during stacking, storage, and shipping.<\/p>\n\n\n\n What is the difference between partition paper and interleaving paper?<\/strong> <\/p>\n\n\n\n They refer to the same function: a separating sheet placed between items. \u201cInterleaving\u201d emphasizes inserting a sheet between each layer, while \u201cpartition\u201d and \u201cslip sheet\u201d are used interchangeably in industrial packaging.<\/p>\n\n\n\n What makes good interleaving paper?<\/strong> <\/p>\n\n\n\n A smooth, non-abrasive surface, a clean and low-impurity composition, neutral pH so it does not stain or tarnish, and consistent fiber quality so it sheds little dust. For silver and copper, a sulfur-free grade is important to prevent tarnish.<\/p>\n\n\n\n What industries use partition paper?<\/strong> <\/p>\n\n\n\n Glass and display manufacturing, steel and stainless processing, electronics and PCB production, and precious-metal handling all use partition paper to protect surfaces during stacking and transport.<\/p>\n\n\n\nCommon Uses by Industry<\/strong><\/h2>\n\n\n\n
