Package Environmental Testing

Package environmental testing is used to evaluate how product packaging systems perform when subjected to different environmental conditions. Westpak offers package environmental testing services that enable manufacturers to analyze how their product packaging systems perform in various climates.


What Is Package Environmental Testing?

Environmental conditions can have a significant impact on product packaging. When products are in transit or storage, they may be exposed to extreme temperatures, different levels of humidity, and other environmental factors.

With environmental package testing from Westpak, you can analyze how your product packaging performs under varying conditions. Our engineers are experts when it comes to conducting environmental conditioning tests, cold chain tests, and more. These tests allow you to optimize package performance and prevent loss or damage due to adverse environmental conditions.

Importance Of Package Environmental Testing

Package environmental testing is crucial if you want to ensure the safety and integrity of your products. As products are transported, they often move through different climates and environments. Whether your products travel through regions of high humidity or freezing cold conditions, you want to be sure that your product packaging system can effectively protect your products. This helps to minimize product loss, maximize profits, and ensure customer satisfaction.

Additionally, in some cases, environmental package testing may be required if you’re a supplier. Many industries impose specific standards on suppliers in order to prove that their products are safe to be transported. Oftentimes, ASTM and ISTA performance standards require suppliers to complete environmental conditioning tests and demonstrate the effectiveness of their product packaging systems.

Frequently Asked Questions

Get answers to our most frequently asked questions.

What are the standards associated with package environmental testing?

Package environmental testing is associated with multiple industry test standards. Relevant test standards include:

  • ASTM D4332: Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing. 
  • ASTM E171: Standard Specification for Standard Atmospheres for Conditioning and Testing Flexible Barrier Materials. 
  • ISTA 3A: Packaged Products for Parcel Delivery System Shipment 150 lbs (68 kg) or less

What types of products benefit from package environmental testing?

Package environmental testing can be used across a variety of industries but may prove particularly useful to medical device manufacturers. In the medical device industry, sensitive products must be well-protected in order to prevent damage and maintain sterility. Damaged products can pose a safety hazard to end-users and potentially damage the manufacturer’s reputation.

Additionally, certain packaging materials should undergo environmental package testing to evaluate their integrity. Plastic and cardboard packaging, in particular, become vulnerable to deformity or damage when exposed to high temperatures or excessive humidity.

What types of environments can package environmental tests simulate?

Environmental package testing can simulate a range of environments. By subjecting product packaging systems to high and low temperatures, as well as high and low humidity, you can see how well your product packaging is able to withstand extreme environmental conditions.

Which tests may be combined with package environmental testing?

In addition to package environmental testing, you may conduct other tests to evaluate package integrity while in transit. Compression testing, vibration testing, and other types of package testing can be conducted under specific environmental conditions that allow manufacturers to better understand how packages perform when exposed to a combination of environmental conditions and other transit conditions.
