Guide to Common Thicknesses of Hollow Boards: A Comprehensive Analysis of Suitable Applications for 2mm–10mm厚度
Hollow board (also known as PP hollow board or Wantong board) is a lightweight, robust, waterproof, moisture-resistant, and environmentally friendly plastic sheet. Its... Thickness is a key factor determining performance and application scenarios. According to industry production standards and information from major suppliers, the typical thickness range for hollow boards primarily falls within: 2 mm to 10 mm (2mm-10mm) between them. Different thicknesses correspond to different load-bearing and protective requirements:
-
Lightweight packaging and advertising displays (2mm-3mm) ：
Hollow boards within this thickness range are lightweight and cost-effective, making them suitable for applications such as product lining pads, lightweight blade-card dividers, display stands, and signage—scenarios that do not demand high strength. They offer excellent cushioning and basic protective functions. -
General-purpose周转 and logistics packaging (4mm-6mm) ：
4mm–6mm is the most widely used and common thickness. It is widely used in the manufacture of various hollow-board turnover boxes (such as nine-foot, "field" shape, and "川" shape pallets), logistics boxes, folding boxes, parts bins, and dividers. This thickness offers a balanced combination of strength, weight, and cost-effectiveness, meeting the general protective requirements of internal factory logistics, warehousing and transportation, as well as industries such as auto parts and electronics. -
Heavy-duty protection and construction formwork (7mm–10mm and above) ：
Thicker boards (7mm–10mm) offer superior compression and impact resistance, making them suitable for packaging heavy-duty equipment, large moisture-proof pallets, temporary barriers on construction sites, and even as... Plastic hollow construction formwork Use.
Select key points and customized advantages ：
- Gram-weight associated hardness In addition to thickness, the weight per unit area (grammage, e.g., 900 g/㎡ for a standard 5 mm board) directly affects the board’s hardness: the higher the grammage, the harder and denser the board material will be.
- Highly customizable and flexible : All mainstream hollow board manufacturers support it. Non-standard customization Depending on specific load-bearing requirements, cost budgets, and usage environments, you can select or customize specific thicknesses—from 2 mm to 10 mm or even wider—along with tailored colors, dimensions, and special features such as antistatic properties.
- Quality control When selecting, pay attention to whether the board surface is smooth and flat, with evenly spaced ribs, and free of defects such as bubbles, cracks, or deformations. Also ensure uniform thickness.
Summary A thickness range of 2 mm to 10 mm is the most common and practical for hollow-core panels, covering a wide variety of needs—from lightweight packaging to heavy industry. By clearly defining your load-bearing requirements, protection level, and budget, you can select the most suitable solution from our standard thickness options, or consult with a professional manufacturer to obtain custom-thickness services, thereby fully leveraging the lightweight, durable, and versatile advantages of hollow-core panels.
