Why has honeycomb board become the preferred material for luggage and bag linings?
For a long time, the luggage and bag manufacturing industry has relied heavily on traditional lining materials such as EVA and pearl cotton. However, these materials suffer from drawbacks including heavy weight, susceptibility to deformation, and poor environmental performance. As consumers increasingly demand lighter and more durable luggage and bags, hollow-core panels (PP honeycomb panels), with their unique structural advantages, have become the industry’s new favorite.
The Three Core Advantages of Hollow Board
-
Lightweight weight reduction
The honeycomb structure reduces the material's weight by 30% to 50%, effectively lowering the overall weight of luggage and making it particularly suitable for products such as travel bags and carry-on suitcases. -
Outstanding stress resistance
Tested according to ISO 2248 standard, the vertical compressive strength can reach 5–8 tons/㎡, perfectly protecting the items inside the box from compression. -
Environmentally friendly and recyclable
Made from polypropylene (PP), 100% recyclable and compliant with the EU RoHS environmental directive.
Real-world application scenarios
-
Business suitcase A thickness of 3mm is sufficient to meet the protective needs of the computer compartment.
-
Photography equipment bag Custom groove design for securing expensive equipment
-
Medical bag Antibacterial coating treatment meets medical standards.
Shopping Guide
It is recommended to choose manufacturers certified by SGS, with particular focus on:
✓ Basis weight (typically 300–800 g/㎡)
✓ Surface compounding process (whether laminated)
✓ Temperature resistance range (-30℃ to 80℃ is optimal)
High-quality hollow-core board liners currently available on the market can extend the service life of luggage and bags by 2 to 3 times. Although the unit price is 15% to 20% higher than that of traditional materials, the overall cost-effectiveness has significantly improved.
