The bag lining is optimally made from PP hollow board—a versatile solution with lightweight and eco-friendly properties.
The choice of lining material for luggage directly affects both the product’s durability and user experience. Thanks to its lightweight, impact-resistant, moisture-proof, and corrosion-resistant properties, PP hollow board has become an ideal choice for the luggage manufacturing industry. This new type of plastic sheet is made primarily from polypropylene and formed into a hollow structure through an extrusion molding process. Not only does this significantly reduce the overall weight, but it also boasts excellent mechanical performance, effectively protecting the items inside the luggage from damage caused by compression and vibration.
Material Properties and Core Advantages
The thickness of PP hollow boards ranges from 2 to 10 mm, and their dimensions can be customized according to the design requirements of luggage and bags, meeting various load-bearing needs. The surface is smooth and supports multi-color customization (such as blue, white, black, and transparent), making it ideal for brand printing and visual design. This material is non-toxic and odorless, complies with environmental standards, and features special properties including antistatic, flame-retardant, and UV-resistant characteristics. It is well-suited for high-end electronic products or luggage designed for use in specialized environments.
Production Process and Industry Compatibility
Hollow board is manufactured by combining extrusion molding with die-cutting processes. High-precision machining is achieved through automated cutting machines and precision die-cutting equipment, enabling the production of complex structures such as partitions, blade holders, and frames. This flexibility allows it to be used not only for lining luggage and bags but also extensively in applications like automotive accessory trays, agricultural fruit and vegetable crates, and advertising display stands—thus realizing "one material, multiple uses."
Dual Value of Environmental Protection and Economic Efficiency
PP hollow boards can be reused more than 50 times and, after disposal, can be recycled and remade. Compared to traditional cardboard, they can reduce packaging costs by as much as 66%. Their waterproof properties prevent deterioration in humid environments, thereby extending the service life of luggage and packaging. Taking a 4mm-thick board as an example, its weight is only 700 grams per square meter, significantly reducing logistics and transportation costs and aligning with the modern manufacturing trend of cost reduction and efficiency enhancement.
Conclusion
As a revolutionary material for luggage and bag linings, PP hollow board is reshaping the standards of the packaging industry thanks to its lightweight design, high-strength protection, and sustainable advantages. Whether it’s for travel cases, tool bags, or cases for precision instruments, choosing a hollow board lining means striking the right balance between quality and environmental friendliness—while also enhancing brand value and market competitiveness.
