What PP hollow sheet is
PP hollow sheet is a twin-wall polypropylene board made with a lightweight fluted structure. It is also called PP corrugated sheet, corrugated plastic sheet, or Coroplast-style sheet in different markets.
The hollow structure keeps the sheet light while improving impact resistance, bending strength, and handling efficiency. For buyers, this means lower transport weight and easier processing compared with many solid plastic boards.
Common advantages
The material is waterproof, moisture-resistant, reusable, easy to cut, and available in custom colors, thicknesses, and surface treatments. It can also support printing for signs, packaging labels, and branded logistics use.
Configuration inputs commonly include thickness, sheet size, basis weight, colour and any required surface treatment. Options such as corona treatment, UV stabilisation or antistatic material should be confirmed against the intended application and the available product documentation.
Where it is used
PP hollow sheet is used for yard signs, retail displays, floor protection, reusable packaging, pallet layer pads, box dividers, agriculture trays, and industrial protection boards.
For procurement, the key is to match thickness, weight, flute direction, color, and surface treatment to the actual working environment instead of selecting by thickness alone.
