Colored PP Hollow Board
PP hollow board, also known as polypropylene hollow board, is a lightweight sheet made from polypropylene (PP) through extrusion process. Due to its cross-section resembling the hollow structure of corrugated paper, it combines the durability of plastic with the lightness of cardboard.
In simple terms, you can think of it as a "plastic corrugated cardboard that is never afraid of water".
Core feature
- Lightweight yet sturdy: The weight is very low (similar to that of corrugated paper of the same thickness), but it has strong compressive and impact resistance, and is not prone to tearing.
- Waterproof and moisture-proof: This is the main reason why it replaces cardboard. The PP material does not absorb water at all. Even if it is soaked in water, it will not rot or mold.
- Chemical resistance: Resistant to acids, alkalis and oil stains. Suitable for use in industrial or chemical environments.
- Non-toxic and environmentally friendly: PP is a food-grade eco-friendly material (many lunch boxes are made of PP). It is non-toxic and odorless, and can be 100% recycled and reused.
- High processing flexibility: Easy to cut, sew, glue, print, and can also be made into a folding structure.
Common Applications of PP Hollow Sheet in Various Industries
1 Industrial packaging (the most extensive):
Re-usable Transport Boxes: Used instead of cardboard boxes for the logistics transfer of automotive parts, electronic components, and agricultural products (fruits and vegetables). Because they can be cleaned and durable, they usually last for 2 to 5 years. Once used up, they can be recycled to earn money, making them the preferred choice for many factories when implementing "green packaging".
Partition and knife holder: Use them as partitions in the shipping box to prevent the precision parts from colliding.
2 Architecture and Agriculture:
Building protection: Temporary fences at the construction site, protection for the floor during decoration (placed on the floor to prevent the floor from being scratched).
Polytunnel： As a heat insulation layer or insulation covering material.
3 Daily and Retail:
Storage boxes/cabinets: There are many items online claiming to be "foldable storage boxes", but they are actually made of PP hollow boards.
Delivery packaging: Some fresh food that requires cold chain storage (such as crabs and fruits) are packaged in this type of box because it can withstand weight and is not prone to condensation water.
4 Advertising display:
Interior and exterior photo display boards: community notice boards, temporary guidance signs, promotional push-out advertisements. Because they are lightweight, do not get wet easily, and have low costs.
5 Agriculture Industry:
Greenhouse Panels and Cladding: In agriculture, PP Hollow Sheets are used for greenhouse panels and cladding due to their weather-resistant and UV-stabilized properties. They help in maintaining a controlled environment for plants, providing insulation while allowing adequate sunlight penetration.
Protective Ground Covers: Farmers also use these sheets as protective ground covers to prevent soil erosion and control weed growth, thereby promoting healthier crop yields.
Summary of advantages and disadvantages
Advantages:
Waterproof, moisture-proof, pest-proof
Resistant to impact and not prone to cracking
Non-toxic, odorless, environmentally friendly and recyclable.
The price is moderate (cheaper than corrugated board, more expensive than ordinary cardboard, but it has the advantage of being recyclable)
Disadvantages:
Limited load-bearing capacity: Although it has good impact resistance, as a structural component, its rigidity is not as good as that of wooden boards or metal plates. When heavy items are placed on it, it is prone to bending and deformation.
Not resistant to high temperatures: The heat resistance of PP material is generally below 100℃. It tends to soften and deform in high-temperature environments.
Surface prone to scratching: The surface has low hardness. If used as a display board, it is likely to leave scratches during transportation.
