What Makes Weather-Resistant Boxes Different?
Standard corrugated boxes use starch-based adhesives that break down when exposed to moisture. Our weather-resistant boxes feature water-resistant adhesive (WRA) that maintains bond strength even in high humidity (up to 95% RH) and wet conditions. This makes them ideal for:
- Outdoor storage and jobsite protection
- Shipping to coastal or tropical climates
- Marine and naval applications
- Cold storage and refrigerated environments
- Military and defense logistics
Military Specifications: W5c and V3c Corrugated
W5c boxes are weather-resistant double-wall corrugated designed for heavy-duty protection. They meet military specification MIL-PPP-B-636 and are commonly used for shipping electronics, communications equipment, and field supplies.
V3c boxes are tri-wall corrugated providing the highest level of protection for sensitive equipment. These exceed standard shipping requirements and are approved for international military logistics.
Common Applications
Electronics and Sensitive Equipment
Protect circuit boards, sensors, and electronics from moisture damage during storage and transit. The water-resistant construction prevents condensation from penetrating the box.
Outdoor Storage
Unlike standard boxes that deteriorate outdoors, weather-resistant boxes maintain structural integrity when stored on job sites, warehouses without climate control, or outdoor staging areas.
Military and Government Contracts
Compliant with federal military specifications, these boxes are approved for defense contractors, government agencies, and military supply chains.
How to Choose the Right Weather-Resistant Box
For standard weather protection: W5c double-wall is sufficient for most applications including light electronics, parts, and general outdoor storage.
For maximum protection: V3c tri-wall is recommended for heavy equipment, international shipping, or when items will be exposed to extreme conditions for extended periods.

Frequently Asked Questions
Are these boxes waterproof?
They are water-resistant, not waterproof. The WRA adhesive prevents moisture from delaminating the corrugated layers, and the thick walls resist water penetration better than standard boxes. For complete waterproof protection, consider using with poly liners or shrink wrap.
Can I use these boxes for long-term outdoor storage?
Yes, but we recommend covering them or storing under a shelter. While weather-resistant boxes hold up much better than standard corrugated, prolonged direct exposure to rain will eventually degrade any paper-based material.
Do you offer custom printing on weather-resistant boxes?
Yes! We can print your logo, handling instructions, or military spec markings. Contact us for custom printing quotes and minimum order quantities.
What's the lead time for military-spec boxes?
Stock sizes typically ship within 3-5 business days. Custom sizes or large military orders may require 2-3 weeks. Rush production available for urgent government contracts.
