How to select high quality PP hollow boards?

PP hollow board is a newly emerging material that plays an important role in many fields. If you want to purchase some but don't know how to select high-quality pp hollow boards, then this simple guide can offer you some help.

Visual Inspection:Color and Surface

The first step in choosing a good PP hollow board is to check the surfaces. High-quality boards have a uniform color and a smooth, glossy surface. If you hold a virgin PP board up to the light, you’ll notice it has consistent transparency (for clear boards) or a vibrant, even hue (for colored ones). While low quality hollow board often look dull or have a yellowish tint, and you might spot tiny impurities or specks on the surface. These boards are more likely to feel brittle when you bend them, and they won’t last as long as high quality pp hollow boards.

Tactile Sensation: Smooth and Neat

A quality PP hollow board should have a clean, professional look. Run your hand over the surface—it should be smooth without any bumps, bubbles, or rough patches. Bubbles larger than a pinhead are a red flag, as they can weaken the board.

Check the edges too. They should be neatly cut without burrs or jagged bits. Burrs not only look bad but can also cause the board to crack over time. For multi-layered boards, make sure the layers are well-bonded without any visible gaps.

Do a quick test: simple checks for performance

You don’t need lab equipment to gauge a hollow board’s quality. Here are some easy tests:

Bend test: Gently bend the board. A high-quality one will flex without forming white stress marks or cracking. If it snaps or shows obvious white lines, it’s likely made from poor materials.

Weight check: PP is a lightweight material. If a board feels unusually heavy for its size, it might contain fillers that compromise its strength. A good PP hollow board should feel light but sturdy.

Water test: Pour a little water on the board and let it sit for a few minutes. Wipe it off—there should be no water stains or signs of absorption. High-quality PP hollow board is naturally water-resistant.

Think about your needs: match the hollow board to its use

Different uses call for different board features:

For packaging light items: A 2-3mm thick board is usually enough. It should be flexible enough to protect delicate goods without adding too much weight.

Heavy-duty packaging: Go for a 4-6mm thickness. The honeycomb structure it has can distributes weight better and offers more support.

Outdoor use: Choose a board with UV protection. This prevents it from fading or becoming brittle in the sun. You can ask the supplier if the board is suitable for outdoor use.

Food packaging: Make sure the board is food-grade. It should have a clean smell and meet safety standards—don’t hesitate to ask for relevant certifications.

Choose a reliable supplier: trust matters

A reputable supplier can make all the difference. Looking for a reliable company can largely guarantee the quality of hollow boards. Meanwhile, although the price is important, don't just buy the cheapest one. Circuit boards that are slightly more expensive but have a longer service life and better performance are usually a better investment.
