Key Features of Gokai PP Hollow Sheet

PP Hollow Sheet is a lightweight, long-lasting twin-wall plastic sheet made of polypropylene (PP). It has a hollow, fluted structure with two flat outer surfaces connected by internal vertical ribs, giving it a high strength-to-weight ratio. PP Hollow Sheet (also known as Polypropylene Hollow Sheet, PP Corrugated Sheet, or PP Twin-Wall Sheet) is a lightweight, extruded structural material. It has a distinctive double-wall profile, with two flat polypropylene walls connected by a series of vertical ribs to form a hollow, fluted core.

· Good Insulation Properties: The hollow core provides thermal and sound insulation.

· Easy to Process: Can be cut, die-cut, scored, folded, printed, and welded with standard tools.

· Lightweight and High Strength: The hollow structure delivers an excellent strength-to-weight ratio, providing rigidity without excessive weight.

· Waterproof and Moisture-Resistant: Being inherently non-porous, it does not absorb water, preventing mildew, swelling, or warping in humid conditions.

· Chemical and Corrosion Resistant: It withstands most chemicals, oils, and corrosive environments without degrading.

· Durable and Impact-Resistant: It offers good impact resistance and a long service life (reportedly 4-10 times longer than corrugated paper).

· Eco-Friendly and Recyclable: Made from 100% polypropylene, these sheets are fully recyclable and non-toxic.

· Thermal and Sound Insulation: The hollow ribs create air pockets that provide moderate thermal insulation and sound-dampening properties.
