Custom Corrugated PP Hollow Sheet Stock
Corrugated PP hollow sheet stock is an extruded polypropylene sheet featuring a hollow internal structure. Vertical ribs bridge the top and bottom surfaces, delivering high structural stiffness at a fraction of the weight of solid plastic boards.
Supplied in custom lengths and standard thicknesses from 2mm to 7mm (widths up to 2600mm), this versatile stock is designed for downstream fabrication into reusable boxes, layer pads, ESD packaging, construction covers, and outdoor signage.

Key Performance Advantages
High Strength-to-Weight Ratio: Internal rib support provides essential sheet rigidity while significantly reducing tare weight for shipping and handling.
100% Waterproof & Chemical Resistant: Unlike paper corrugated board, PP hollow sheets do not absorb moisture, oils, or common industrial chemicals. They can be routinely washed and reused.
Easy Conversion & Secondary Processing: Compatible with standard conversion equipment for die-cutting, scoring, sonic welding, riveting, screen printing, and digital UV printing.
Eco-Friendly & Recyclable: Manufactured from thermoplastic PP material, fully recyclable at the end of its product lifecycle.
Downstream Printing & Conversion Capabilities
We supply semi-finished sheet stock fully prepared for specialized downstream fabrication:
Extrusion Processing Workflow:
- Sheet Stock Extrusion - Surface Corona Treatment - UV/Screen Printing -Die-Cutting/Scoring - Finished Component
- Printing Options: Surface Corona treatment is available to improve ink adhesion for direct UV flatbed printing and screen printing (logos, warnings, and custom graphics).
- Fabrication Compatibility: Cutting, die-cutting, slotting, scoring, creasing, sonic welding, edge-sealing, punching, and custom hole-drilling.

FAQ
Q: What is the difference between Corrugated PP Hollow Sheet and standard cardboard?
A: Corrugated PP hollow sheet is made from 100% thermoplastic polypropylene, making it completely waterproof, chemical-resistant, and reusable. Unlike paper cardboard, it does not degrade in damp environments and has a significantly higher burst strength for returnable packaging applications.
Q: How do I know if I need Corona surface treatment for my sheets?
A: If you plan to print graphics, logos, or text on the sheets using UV digital flatbed printing or screen printing, Corona treatment is required. It increases the surface tension (dyne level) of the plastic, allowing inks to adhere firmly without peeling or scratching off.
Q: Can I order custom sheet sizes instead of standard market sizes?
A: Yes. We extrude sheets to yourSince you didn't include the source text in your message, please provide or paste the content you would like me to review.
