Material Structure & Thickness Selection Guide

Material Advantages
High Strength-to-Weight Ratio: The internal rib structure significantly reduces overall weight while maintaining high structural rigidity compared to solid plastic.
Moisture & Chemical Resistance: Highly resistant to water, humidity, oils, and common industrial chemicals, ensuring durability in harsh environments.

Thickness Selection Guide
2 mm to 3 mm: Ideal for lightweight applications such as printed signage, display boards, lightweight box dividers, protective inserts, and surface protection.
4 mm to 5 mm: The primary standard range for general industrial and returnable packaging. Perfect for returnable boxes, layer pads, automotive component packaging, and structural protection panels.
6 mm to 7 mm: Engineered for high rigidity and heavy-duty performance. Recommended for heavy-load packaging, structural dividers, and large unsupported protective panels.

Functional Grades & Selection Notes

UV-Resistant Grade

Essential for prolonged outdoor exposure (e.g., agricultural protection, outdoor signage) to prevent yellowing and material embrittlement.

Anti-Static Grade

Designed for general electronic components packaging to control static charge accumulation.

Conductive Grade

Recommended for sensitive ESD packaging (e.g., PCB transport containers). Standard PP is non-conductive and should not be used for critical ESD protection.

Flame-Retardant Grade

Formulated to meet defined fire safety specifications (UL94) for interior installations or high-risk industrial environments.

Processing & Custom Fabrication

Surface Treatment & Printing

Corona treatment available for superior ink adhesion in UV, screen, and digital printing.

Precision Fabrication

Sheet cutting, custom die cutting, crease folding, sonic welding, and riveting.

Custom Containers

Complete assembly of returnable totes, folding boxes, and custom internal divider systems based on customer CAD drawings or physical samples.

Packaging, Logistics & Export Handling

Sheet Packaging: Packed on export-grade wooden or plastic pallets with corner protection and stretch wrap, or bulk-loaded into containers to maximize space utilization.

Roll Packaging: Wrapped in protective film and secured on sturdy inner cores.

Global Shipping: Extensive experience with Full Container Load (FCL) and Less than Container Load (LCL) global transport.

FAQ

Q: What is the difference between PP hollow sheet and solid PP sheet?

A: PP hollow sheet features an internal fluted structure that provides high stiffness with a significant weight reduction, making it cost-effective for packaging and displays. Solid PP sheet has a continuous solid cross-section, suited for heavy mechanical machining or solid barrier applications.

Q: Can these sheets be used outdoors long-term?

A: Standard PP hollow sheets are suitable for short-term outdoor use. For prolonged sunlight exposure, you should specify our UV-resistant grade to prevent degradation from UV radiation.

Q: Are PP hollow sheets recyclable?

A: Yes, PP hollow sheets are produced from 100% polypropylene and are fully recyclable within standard industrial PP recycling streams.

Q: How do I choose between anti-static and conductive grades for electronics?

A: Specify the anti-static grade for general static dissipation, and the conductive grade for sensitive ESD applications (such as PCB transportation). Always state your required surface resistance range when inquiring.

Q: When should I choose roll format instead of flat sheets?

A: Roll format is ideal for thin gauges (typically 2 mm to 3 mm) when continuous long coverage is required, such as floor protection in construction, long tree wrap, or automated high-volume die-cutting lines.
