Mantis PP Hollow Sheet: Lightweight and versatile plastic sheet

• May 26, 2023

Overview of PP Hollow Sheet.PP Hollow Sheet, also known as PP plastic hollow sheet, Wantong sheet or lattice sheet, is a new type of plastic sheet with light weight and high strength. This sheet is made of polypropylene as the main raw material through extrusion molding process. Its unique structural feature is that the holes are arranged regularly in the cross section of the sheet to form a hollow design.

Product structure and characteristics.The core structural feature of PP Hollow Sheet lies in its hollow design:Three-layer structure: usually composed of two layers of flat plates with regularly arranged ribs in between.Honeycomb arrangement: the internal support structure is mostly arranged in a honeycomb or lattice shape.Air layer: the hollow part forms an air layer to provide heat insulation and sound insulation.This special structure gives PP Hollow Sheet the following significant characteristics:Lightweight: the density is only 1/3-1/2 of the solid board.High strength: the hollow structure provides excellent impact and pressure resistance.Environmental protection: 100% recyclable, in line with modern environmental protection requirements.Chemical resistance: good resistance to acids, alkalis and most chemicals.Waterproof and moisture-proof: completely non-absorbent, stable performance in humid environments.Easy to process: can easily perform secondary processing such as cutting, drilling, folding, and thermoforming.Production process.PP Hollow The production of Sheet mainly goes through the following processes:Raw material preparation: polypropylene resin is mixed with masterbatch, additives, etc. in proportion.Extrusion molding: the molten material is extruded and molded by a special extruder.Mold shaping: a hollow structure is formed by a specially designed mold.Cooling shaping: the sheet is solidified by water cooling or air cooling.Traction cutting: cut to length according to customer requirements.Quality inspection: check thickness, flatness, color and other indicators.Packaging and warehousing: protective packaging as required.

Main application areas.With its excellent performance, PP Hollow Sheet is widely used in various industries:Packaging and transportation field.Electronic product packaging lining.Medical equipment transportation pallet.Precision instrument protection box.Logistics turnover box.Replacement of traditional wooden boxes and cartons.Advertising display field.Exhibition display board.Advertising signboard.Product display rack.Indoor and outdoor bulletin boards.Building decoration field.Temporary building partitions.Roof insulation layer.Site protection board.Greenhouse covering materials.Industrial application field.Equipment protection cover.Workshop partition.Clean room board.Anti-static work surface.Other special applications.Children’s products (such as drawing boards, toys).Agricultural seedling trays.Automotive interior parts.Home storage products.Market advantages and development prospects.Compared with traditional packaging materials, PP Hollow Sheet has obvious advantages:Cost-effectiveness: Long-term use cost is lower than cardboard and wood.Service life: Durability far exceeds traditional materials and can be reused.Environmental contribution: Reduce wood use and reduce carbon emissions.Flexible design: Customizable color, thickness and special functions (such as anti-static, flame retardant).With increasingly stringent environmental regulations and the popularization of sustainable development concepts, PP Hollow Sheet has broad market prospects. Future development trends include:High performance: Develop products with higher strength and lighter weight.Functionalization: Add special functions such as anti-UV, antibacterial, and antistatic.Green: Use recycled PP raw materials and bio-based materials.Intelligent: Integrate intelligent tracking technologies such as RFID.Application expansion: Application development in emerging fields such as new energy and medical devices.When choosing and using PP Hollow Sheet, it is recommended to consider the following factors:Thickness selection: Choose different thicknesses of 2mm-10mm according to load-bearing requirements.

PP Hollow As an economical, practical, environmentally friendly and efficient plastic sheet, Sheet is gradually replacing many traditional materials and playing an important role in all walks of life. With the advancement of material technology and the improvement of processing technology, its performance will be further improved, and its application field will continue to expand, providing better solutions for industrial production and daily life. In the pursuit of sustainable development today, PP Hollow Sheet is undoubtedly an innovative material that conforms to future trends.
