ASTM-D5118 V3c and W5c Boxes – Royco Packaging

ASTM-D5118 is the current specification covering weather-resistant corrugated and solid fiberboard shipping containers used in military and industrial packaging. It superseded the older PPP-B-636 specification, so contracts or drawings may still reference the legacy designation even though ASTM-D5118 is now the active standard. Royco Packaging manufactures ASTM-D5118 boxes in-house using traceable weather-resistant board designed to withstand demanding storage and transport conditions. The company can help customers translate an older PPP-B-636 callout into the appropriate current requirement. Royco’s V3C, W5C, and V11C options provide different strength levels while maintaining the moisture-resistant construction expected for military shipping containers.

Royco Packaging offers three ASTM-D5118 board grades for different load and durability requirements. W5C is a weather-resistant corrugated board with a 275-pound bursting strength and is suitable for lighter to medium-duty military shipments. V3C provides a 350-pound bursting strength and is commonly used for standard military packaging, depot shipments, components, and general supplies. V11C is the heaviest option listed by Royco, with a 600-pound bursting strength for more demanding loads. All three grades use weather-resistant treated fiberboard. Royco can manufacture RSC, FOL, FTL, and other configurations, allowing the board grade and box design to be matched to the shipment.

Yes. Royco Packaging states that its ASTM-D5118 containers are made from QPL-traceable board materials. That means the fiberboard used for the box can be traced back to qualified sources associated with the applicable specification requirements. Royco’s in-house manufacturing also allows the company to maintain control over sizing, workmanship, and documentation from raw material through finished container production. For military and government procurement, this traceability can be important during receiving inspection or contract review. Royco can provide supporting compliance documentation with the order, including material certifications or Certificates of Compliance as applicable. Customers should provide any contract-specific documentation requirements when requesting a quote.

Yes. Custom ASTM-D5118 box manufacturing is one of Royco Packaging’s core capabilities. The company can produce V3C, W5C, and V11C containers to project-specific dimensions rather than limiting customers to standard stock sizes. Available configurations include RSC, FOL, FTL, die-cut designs, partitioned boxes, liners, and reinforced constructions for heavier or unusual components. Because production is handled in-house, Royco can work with customers on dimensional requirements, board strength, quantity, and military packaging documentation in the same project. This is useful for defense parts, equipment, electronics, and assemblies that cannot be packed efficiently or compliantly in a generic corrugated container.

Lead time for ASTM-D5118 boxes depends on the board grade, dimensions, configuration, quantity, and whether the order requires a custom design. Royco manufactures these containers in-house and promotes fast turnaround compared with sourcing through a third-party box converter. Standard or straightforward custom runs can therefore move more quickly than highly engineered die-cut or reinforced configurations. Royco does not publish one universal lead time for every ASTM-D5118 order, so the best approach is to request a quote with the required size, V3C/W5C/V11C grade, style, quantity, and documentation needs. The packaging team can then provide a realistic production schedule for that exact order.
