Lightweight PP hollow boards are ideal for short-term and cost-sensitive projects.
Applications:

Temporary indoor and outdoor advertising
Their low weight makes them easy to install, carry, and replace, while still offering waterproof and UV-printable surfaces for high-quality graphics.

This is the most popular category of PP corrugated sheets, offering a balance between strength and versatility.
Applications:
Returnable packaging boxes and crates
Fruit and vegetable packing containers
Logistics layer pads and dividers
Protective sheets for transport and storage
With greater durability compared to lightweight sheets, these are suitable for reusable packaging and supply chain solutions, significantly reducing overall logistics costs.
3. Heavy-Duty Sheets (8–12mm, 900–1800gsm)
Designed for industrial and construction environments, heavy-duty hollow boards deliver excellent impact resistance and long-term durability.
Applications:
Temporary floor and wall protection during construction
Industrial packaging for machinery and heavy parts
Agricultural use such as tree guards and field dividers
Outdoor applications requiring strength and weather resistance
These sheets are strong enough to replace wood or metal in certain protective applications while remaining lightweight and recyclable.
Why Thickness and Weight Matter
Choosing the right thickness and grammage ensures your PP corrugated sheet performs effectively:
Thinner boards save cost and are perfect for disposable advertising signs.
Medium-weight boards provide an optimal balance for reusable packaging.
Thicker boards deliver maximum durability for demanding industrial use.
By understanding the classification, businesses can optimize costs, extend product life, and achieve sustainability goals.
