What are the characteristics of hollow board materials, and what are their application areas in packaging production?
The chemical name for PP hollow board is polypropylene hollow sheet. Its density is only 0.91 grams per cubic centimeter, which is less than the density of water. Among common plastic sheets, polypropylene hollow sheets exhibit exceptionally high heat resistance. They can withstand temperatures ranging from 80 to 100 degrees Celsius and can even be boiled in boiling water. These sheets also possess excellent resistance to stress and a relatively long fatigue life under bending conditions.
Polypropylene hollow boards exhibit excellent electrical insulation properties, with extremely low water absorption and an electrical insulation performance that is unaffected by humidity. The polypropylene hollow board has a very low dielectric constant and dielectric loss factor, which remain stable regardless of frequency or temperature. Moreover, it boasts high dielectric strength, which increases as the temperature rises. These characteristics are particularly advantageous in humid and hot environments. Due to their high mechanical strength, polypropylene hollow boards are often used in applications where superior insulation performance is required.
First, the characteristics of hollow board material are as follows:
1. This product features a three-layer corrugated structure that is structurally sound and offers excellent cushioning performance. At the same time, the three-layer design ensures low material density, thereby reducing material costs—a key prerequisite for gradual market acceptance.
2. The primary material component of hollow-core panels is polypropylene resin. Consequently, hollow-core panel materials exhibit excellent acid resistance, corrosion resistance, and high-temperature resistance. As a result, this product is widely used in specialized industries such as chemical engineering and related fields.
3. Hollow board material, also known as PP hollow board material, is resistant to deformation under the same high-temperature conditions and is easy to process. As a result, it is widely used across various industries to manufacture packaging materials of diverse shapes.
4. Hollow-core board materials readily absorb various color additives, giving them a wide range of colors. As a result, they can be processed into packaging materials of different colors, making it easy to distinguish between product packages.
5. Hollow-core panel materials are non-toxic, odorless, and pollution-free; their waste can be processed and reused twice, which is their greatest advantage over other plastic packaging materials.
Second, the application areas of hollow board packaging;
1. As a hollow packaging box, it can be used for the long-distance transportation and long-term storage of foods such as vegetables, fruits, and flowers, while ensuring excellent anti-corrosion and moisture-proof performance.
2. As antistatic hollow-core turnover boxes and antistatic hollow-core packaging boxes, they can be used for consumer electronics such as automotive electronics, mobile phones, refrigerators, and other household appliances. These boxes are highly effective for process assembly, assembly-line operations, and long-distance logistics. They help eliminate electrostatic damage caused by factors such as friction and environmental conditions. When used to replace cardboard boxes in the packaging of automobile bumpers, headlights, and dashboards, these boxes can be reused, significantly reducing costs.
3. Hollow board products, thanks to their excellent characteristics such as being non-toxic, odorless, and lightweight, are widely used in children’s smart blackboards, advertising slogans, warning signs, small hurdles, and more. They can also be used as back panels for strollers and as bottom pads for strollers.
4. It can be used as stairwell and elevator wall panels, as well as office partition walls. At large-scale shopping mall construction sites, it can also serve as floor protection panels.
5. Can be used as a storage box, cosmetic bag, or lining for various interiors; also suitable for making the bottoms of bird cages and pet cages.
6. Due to its excellent waterproof performance and reusability, it is used as an intermediate partition in glass bottles, mineral water bottles, oil drums, cans, gas storage tanks, and the like, rather than corrugated cardboard or wood.
7. It can serve as a side protection board for steel coils and aluminum coils, as well as for wires, copper wires, plastic pipes, wire reels, and spools.
8. Due to its excellent waterproof performance, it can be packaged in steel pipes, coils, round bars, and other types of steel materials.
