Mantis PP Hollow Sheet: Features, Applications and Advantages

• May 26, 2023

Overview of PP Hollow Sheet.PP Hollow Sheet, also known as PP Hollow Sheet or Plastic Corrugated Sheet, is a lightweight sheet made of polypropylene as the main raw material. Its unique structure is composed of two layers of flat plates connected by vertical ribs to form a regular rectangular or circular hollow channel. This design gives the sheet excellent mechanical properties and lightweight characteristics.

Product Features.Lightweight and high-strength: The density is only 0.92-0.95g/cm³, which is more than 50% lighter than traditional wood boards, but has excellent impact resistance and compressive strength.Environmentally friendly and non-toxic: 100% recyclable, in line with international environmental standards such as RoHS and REACH.Chemical stability: Acid and alkali resistant, corrosion-resistant, non-absorbent, and not affected by humid environments.Heat insulation and sound insulation: The hollow structure effectively blocks heat conduction and sound wave transmission.Processing performance: It can be easily processed by cutting, drilling, folding, thermoforming and other secondary processes.Surface characteristics: It can be made into a smooth surface, frosted surface or printed with various patterns to meet different decoration needs.Production process.PP hollow board is produced by co-extrusion molding process:Raw material pretreatment: PP resin is mixed with masterbatch, modifier, etc.Melt extrusion: Heating and melting through a twin-screw extruder.Mold molding: A specially designed die head forms a hollow structure.Cooling and shaping: Three-roll calender precisely controls thickness and flatness.Traction cutting: Cut into different specifications according to customer needs.Main application area.Packaging industry.Anti-static packaging boxes for electronic products.Turnover boxes for medical devices.Food-grade logistics pallets.Foldable storage boxes.Building decoration.

Temporary building partition walls.Indoor and outdoor advertising display boards.Sun room roof materials.Dust and sound insulation barriers for construction sites.Automobile industry.Automobile interior lining.Luggage compartment partition.New energy vehicle battery protection plate.Agricultural applications.Greenhouse cover panels.Farm partitions.Fruit and vegetable packaging turnover boxes.Other fields.Stationery (folders, pads).Children’s products (toys, teaching aids).Sports equipment (surfboard, snowboard core).Market advantage analysis.Cost-effectiveness: Compared with traditional wood and metal boards, the overall cost is reduced by 30-40%.Service life: Under normal use conditions, it can reach 5-8 years, which is more than 10 times that of ordinary cardboard.Convenient transportation: It can be stacked for transportation, saving more than 60% of logistics space.Flexible customization: Thickness (2-12mm), color (200+ color series), and size can all be customized.International recognition: Passed international certifications such as SGS, FDA, and UL, and export is barrier-free.Future development trends.High performance: Develop special hollow boards such as flame retardant, UV resistant, and conductive.Smart manufacturing: Introduce Internet of Things technology to realize digitalization of production processes.Green upgrade: Application of bio-based PP raw materials, carbon footprint reduced by 50%.Composite application: Develop new types of boards by combining with aluminum alloy, carbon fiber and other materials

PP Hollow As a new environmentally friendly material, Sheet is gradually replacing traditional packaging and building materials, and its application boundaries are constantly expanding with technological progress. With the tightening of global environmental regulations and the development of circular economy, it is expected that the global PP hollow sheet market will grow at an average annual rate of 6.8% in the next five years, playing an increasingly important role in sustainable development strategies.
