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.
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.
As a kind of environmental material, PP hollow sheet widely used abroad. In China, it replaces some corrugated packaging materials step by step. Now, some domestic enterprises are also developing it for building decoration materials.

The main uses of PP hollow sheet
1. Replace corrugated cardboard, board, metal sheet, etc.
2. Industrial panels, protective packaging of various articles, cushions, shelves, partitions, floor sheet, cross sheet, etc.
3. Advertisement and Decoration: display sign, commodity sign, billboard, light box, window display, etc.
6.Household use: temporary partitions, wall panels, ceiling panels, container’s cover, etc.
Polypropylene has good heat resistance, which products can tolerate 100℃ for sterilization. Without external conditions, it is not deformed at 150℃. The melting temperature of PP increased 40% to 50% rather than polyethylene’s, around 160℃-170℃. 100% isotactic polypropylene’s melting point is 176℃.
The chemical stability of polypropylene is very good. Apart from being eroded by concentrated sulfuric acid and concentrated nitric acid, polypropylene is relatively stable to other chemical reagents. However, low molecular weight fatty hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and swell polypropylene. What’s more, its chemical stability is also improved with increasing of crystallinity, so polypropylene is suitable for making all kinds of chemical pipes and fittings, and the corrosion prevention effect is good.
