Honeycomb board, also known as polypropylene honeycomb board, PP honeycomb board, Wantong board, or calcium plastic board, is a new type of eco-friendly packaging material made primarily from polypropylene (PP) resin through an extrusion molding process.
**Structural Features**: The board has a hollow grid structure in the middle, resembling the wavy pattern of corrugated cardboard, but made of plastic, thus combining the lightweight advantage of paperboard with the durability of plastic.

## 5 Key Features of Hollow Panels
1️⃣ Lightweight and high-strength
With a density of only 0.7–0.9 g/cm³—just one-tenth that of steel and one-third that of aluminum—it still offers excellent load-bearing capacity. A 4 mm thick hollow panel can withstand 15–20 kg of pressure per square meter.
### 2️⃣ Waterproof and Moisture-Resistant
Completely waterproof, can be directly washed with water and will not deform even after prolonged soaking. Suitable for humid environments, cold chain logistics, aquaculture processing, and other applications.
### 3️⃣ Corrosion-resistant
Resistant to acids, alkalis, and oil stains, suitable for corrosive environments such as chemical plants, electroplating workshops, and food processing factories.
### 4️⃣ Reusable
Normal service life of 3–5 years, reusable over 50 times—10 to 20 times more than cardboard boxes—with lower overall cost.
### 5️⃣ Eco-friendly and Recyclable
100% recyclable and reusable; can be shredded and regranulated after disposal, meeting environmental requirements for export packaging in Europe and America.

How to Choose a Reliable Honeycomb Panel Manufacturer?
### ✅ Check the raw materials
High-quality manufacturers use brand-new PP pellets, which are odorless and highly durable. Inferior products contain recycled materials, making them brittle, prone to breaking, and emitting a pungent smell.
### ✅ Check the manufacturing process
- **Vacuum Calendering**: Dimensionally stable with excellent flatness
- **Three-Roll Calendering**: Smooth surface finish, but higher cost
Qingdao Yupeng uses vacuum molding technology, offering high cost performance and suitability for most application scenarios.
✅ Check capacity assurance
Manufacturers with two or more production lines can guarantee delivery times, while small workshops are prone to delays during peak seasons.
###### ✅ Check Printing Capability
Choose according to requirements:
- Simple logo → single-color or two-color screen printing is sufficient
- Detailed design → requires four-color offset printing (outsourced processing)
###### ✅ Check minimum order quantity
Standard manufacturers have an MOQ of 1 ton; for small-batch customization, please communicate in advance.
