Package Testing

Package systems play a significant role in the delivery of a product to the customer. Westpak utilizes package performance and integrity testing methods to evaluate package systems.

What is a Package System?

Most products are overpackaged leading to cost overrun and environmental waste.  An optimized package system balances the ruggedness of the product with just enough packaging to provide protection from the point of manufacture to the point of end use. There is a synergy between the product and the package when proper design is employed.

Drop Testing

Drop Testing

Just as the name implies, drop impact testing evaluates the ability of a package to protect the product against collisions that occur in the distribution environment. Read more about Drop Testing

Amazon Package Testing

Amazon Package Testing

Westpak is a member of Amazon's Packaging Support and Supplier Network (APASS) and approved to test and certify products as Amazon Prep-Free packaging (PFP), Ships-In-Own-Container (SIOC), and Frustration-Free Packaging (FFP) for vendors, sellers and manufacturers.

Environmental Conditioning

Environmental Conditioning

One of the first test processes often required prior to conducting physical testing on the package, container, or packaging component being evaluated is Environmental Conditioning. This process brings the item to be tested into equilibrium with specific temperature and humidity conditions prior to testing.

Environmental Conditioning is conducted in an environmental chamber designed to maintain tight controls over temperature and humidity.  The test levels chosen are often typical of what might e encountered during a distribution cycle, or storage for an extended time period.

The temperature and moisture content of the material to be tested is critical.  For example, paper-based materials are hygroscopic and change their strength characteristics as they absorb or release moisture.

Typical Procedures/Protocols

ASTM D4332
ASTM D3103
IEC 60068-2
ISTA 2 & 3 Series
ISO 2233
MIL STD 810G

Distribution Testing

Distribution Testing

Distribution Testing is the practice of conducting tests that simulate the distribution environment in a laboratory. Lab testing provides a controlled and repeatable setting where the packages can be evaluated. Read more about Package Distribution Testing

Impact Testing - Horizontal

Impact Testing - Horizontal

Westpak's Horizontal Impact Test System (HITS) primarily tests products and package systems for damage resistance due to railcar coupling. However, this versatile system also tests for sensitivities to other types of horizontal impacts including rough forklift handling and truck docking.

The HITS is capable of handling 5,000+ pound loads at impact velocities up to 10 mph. Westpak’s test engineers can fine-tune the impact velocity and impact pulse shape to exactly the waveform necessary for almost any conceivable application. Mechanical programmers simulate railcars equipped with both standard and cushioned undercarriage draft gear.

Unique Test Capability
Westpak is pleased to be the only 3rd party accredited test laboratory on the West Coast to offer Horizontal Impact testing. With the HITS, Westpak can simulate all types of transportation hazards in one laboratory location saving you time and expense in the testing function.

Typical Procedures/Protocols
ASTM D4003
ASTM D880
AIAG RC-9
