Polyreflex polypropylene (PP) corrugated sheet

is made of polypropylene (PP) copolymer, homopolymer resin and some fillers. It is also called twinwall PP panel, fluted polypropylene sheet, corflute sheet or coroplast sheet.

Polypropylene corflute sheet is an extruded corrugated sheet consisting two flat walls connected by vertical ribs, or in the pozidrive structure. 

PP corrugated sheet is absolutely harmless and odourless, and moisture resistance & anticorrosion. Its outstanding properties such as strong, lightweight, various colors make it good in packaging, advertising, construction, agriculture and industry uses.

lightweight plastic sheet


Polypropylene corrugated sheet is designed as a double-wall hollow structure, which is lighter in weight and has good strength, makes it more convenient to use.

coroplast suitable for printing

Excellent Printing Ability

The corona-treated polypropylene fluted sheet has good ink absorption capacity. Suitable for digital UV printing and screen printing.

recyclable pp corrugated sheet


Polyreflex corflute sheet is 100% recyclable. It is made of polypropylene raw materials, and our products have passed RoHS, REACH and heavy metal testing, and are food-grade environmentally friendly materials.

chemical resistant coroplast sheet


Lightweight polypropylene sheet has the characteristics of corrosion resistance, weather resistance and high temperature resistance, can be used in humid environment and outdoors.

Custom Processing coroplast sheet

Easy Processing

Polypropylene corrugated sheet can be easily processed, such as die-cutting, sealing, welding, bending, CNC engraving, and printing.

Structure Type

colored corflute sheet
wide rib fluted sheet

Wide ribs allow the corflute sheet to have a lower weight, stronger and harder surface, and the larger hollow allows the support rod to be inserted.

narrow pp fluted sheet

Narrow ribs make the thin corflute sheet lighter, stronger and easier to produce. 

S-lines pp fluted sheet

The core ribs of the corflute sheet are S-lines. S corflute sheet is much more strong than those sheets with narrow or wide ribs sheet. 

flat pp fluted sheet for printing

Polyreflex printing-grade corflute sheet has very flat surface and is suitable for printing signs.
