Hollow board: A packaging material solution with eco-friendly and energy-saving features.
I. Definition of Hollow Board
Hollow board, also known as corrugated board or PP hollow board, is a lightweight sheet material made from polypropylene (PP) through a high-temperature extrusion molding process. Its cross-section features a grid-like structure and boasts both eco-friendliness and high strength. It finds extensive applications in various fields, including logistics packaging, industrial manufacturing, and architectural decoration. Compared to traditional corrugated cardboard, hollow board offers advantages such as moisture resistance, corrosion resistance, and recyclability, making it perfectly aligned with the requirements of modern green production.
II. Core Advantages of Hollow Board
- Lightweight design The hollow structure reduces the density of the hollow board to just one-third that of traditional materials, lowering transportation costs while enhancing operational convenience.
- Environmentally friendly and recyclable Hollow board can be 100% recycled and reused, and its non-toxic and harmless properties meet the hygiene standards of industries such as food and pharmaceuticals.
- Multifunctional application
- Buffer packaging It can be used for shock-resistant protection of electronic components and precision instruments.
- Logistics turnover Hollow board boxes can replace wooden boxes, thereby reducing resource waste.
- Ad display Capable of customizing irregular-shaped structures to meet the needs of commercial exhibitions.
- Significantly economical The single-use cost of honeycomb panels is only one-fifth that of corrugated cardboard, and their reuse rate can exceed 50 times.
III. Guide to Selecting Hollow Core Panels
- Clearly define the use case
- If antistatic requirements exist, special hollow boards containing conductive masterbatches should be selected.
- When used in high-temperature environments, prioritize using aging-resistant panels.
- Detect key indicators
- Thickness: The standard thickness ranges from 2 to 10 mm; the greater the load-bearing requirement, the thicker the material needed should be.
- Surface treatment: The printing/lamination process can affect the anti-fouling performance.
- Verify supplier qualifications It is recommended to choose manufacturers that are ISO9001-certified and have large-scale production lines—such as industry leaders like Zibo Hongwei Plastics.
IV. Industry Application Trends
With the advancement of the nation’s “dual-carbon” policy, the application of hollow board products is accelerating in emerging fields such as new-energy battery transportation and fresh-food cold-chain packaging. Data shows that in 2024, the domestic market size for hollow boards exceeded 8 billion yuan, with an annual growth rate reaching 12%. It is recommended that companies, based on specific customer needs and in combination with derivative products such as hollow-board knife cards and dividers, develop systematic packaging solutions.
