PP Hollow Sheet(corrugated sheet/two-wall sheet)

PP hollow sheet is a kind new material of Light weight (hollow structure), non-toxic, pollution-free, waterproof, shockproof, anti-aging, corrosion resistant and colorful. Compared with the traditional paperboard products, PP hollow sheet has the advantages of moisture-proof, corrosion resistance and so on; and compared with injection-molding products, environmental PP hollow sheet has the advantages of earthquake resistance, flexible structure design and it is also unnecessary to open injection mould. What’s more, in the way of controlling the raw material, those materials of static-free, electric and other materials can be added in it so that it can have electric, static-free and other characters. For static-free sheet, the surface resistivity can be controlled between 106Ω·m and 1011Ω·m; for electric sheet, the surface resistivity can be controlled between 103 Ω·m and 105Ω·m.

Application:

PP hollow sheet is a new environmental packing material, widely applied to electronics, packaging, machinery, light industry, postal, food, medicine, pesticide, household appliances, advertising, decoration, cultural products, optical magnetic technology, bioengineering, medicine and health and other fields.

PP hollow sheet characteristic:

non-toxic, odorless; environmental; moisture-proof; corrosion-resistant; light weight, tensile resistance, high strength and other properties;

The surface can be printed or pasted; different colors can be produced according to the demand; by adding flame retardant, the produced hollow sheet of the flame-retardant effect can be extinguished.

The main uses of PP hollow sheet

1. Replace corrugated cardboard, board, metal sheet, etc.

2. Turnover box, spare parts turnover box, food container, beverage container, pesticide packing box, inner packaging of precision instruments, packaging gasket and partitions for electronic components , and transport storage turnover box, etc.

3. Industrial panels, protective packaging of various articles, cushions, shelves, partitions, floor sheet, cross sheet, etc.

Physical property

Polypropylene is non-toxic, odorless and milky high-crystalline polymer, which is currently one of the lightest of all plastics.

Electrical property

It has high dielectric coefficient and can be used to make heated electrical insulating products with the increase of temperature. Its breakdown voltage is also very high, which is suitable for electrical accessories and so on.
