Overview
ASTM D5168-22: Standard Practice for Fabrication and Closure of Triple-Wall Corrugated Fiberboard Containers establishes best practices for creating and sealing triple-wall corrugated fiberboard containers. This international standard, developed by ASTM International, addresses key construction styles and outlines requirements to ensure containers provide optimal protection and performance during handling, shipping, and storage. Triple-wall corrugated fiberboard containers are commonly used to unitize products, protect goods against harsh environmental conditions, and support manual or mechanical handling.
Key Topics
-
Container Fabrication and Closure
The standard covers methods for fabricating new triple-wall corrugated fiberboard containers and specifies necessary closure techniques. It defines styles, construction requirements, and eligible closure materials such as staples, strapping, and tape.
-
Performance and Durability
ASTM D5168-22 details essential performance characteristics including puncture resistance, short column crush strength, caliper (thickness), and adherence of facings and corrugated mediums. These requirements safeguard the contents throughout the supply chain.
-
Design Classes and Styles
- Style A: Regular slotted containers
- Style B: Full telescope containers
- Style C: Half slotted containers with removable covers
Each style has specific requirements for dimensions, overlap, and closure methods.
Classes include options for weather resistance (for export or humid conditions), non-weather-resistant uses (domestic/favorable climates), and fire retardancy.
-
Compliance and Certification
Manufacturers must certify that supplied containers meet the standard’s requirements. Weather-resistant containers require specific marking, including date, grade, and compliance details.
-
Ordering and Customization
The standard specifies procurement information, allowing purchasers to select container class, style, dimensions, closure method, and additional features such as pallet bases or reinforced covers.
Applications
Triple-wall corrugated fiberboard containers fabricated and closed according to ASTM D5168-22 are highly suitable for:
-
Heavy-duty Industrial Packaging
Used for unitizing bulky, heavy, or irregularly shaped products that require robust protection during shipping and storage.
-
Shipping in Challenging Environments
The weather-resistant and fire-retardant classes support shipments that face exposure to humidity, extreme climates, or regulatory safety requirements, such as for hazardous materials.
-
Automated and Manual Handling
Containers are designed for efficient compatibility with logistics operations, including manual handling, mechanized warehouse systems, and palletization.
-
Government and Regulatory Use
This standard is recognized and approved by agencies such as the U.S. Department of Defense and is compatible with related federal and international shipping regulations.
