What Is Environmental Package Testing?
Environmental package testing exposes packaging to controlled temperature, humidity, UV, and chemical conditions to evaluate how packaging materials and configurations perform over time and under stress. The testing category covers three main areas: accelerated aging to project shelf life and validate expiration dates, environmental stress crack resistance (ESCR) to evaluate plastic container durability under chemical exposure, and UV and conditioning tests to confirm material stability through storage and distribution environments.
Results give manufacturers documented evidence that packaging holds up through its intended use environment before products reach the market, and provide the data needed for regulatory submissions, shelf life claims, and distribution qualification programs.
Why Does Environmental Package Testing Matter?
Packaging that has been validated only for mechanical performance can still fail when exposed to the temperature extremes of a warehouse, the humidity of a shipping container, or the UV conditions of retail display. Environmental testing closes that gap by subjecting packaging to the conditions it will encounter across its full lifecycle.
For medical device and pharmaceutical manufacturers, accelerated aging data is required documentation for FDA submissions and shelf life labeling claims. For chemical and industrial shippers using plastic packaging, Appendix B compatibility testing establishes that the packaging material is chemically compatible with the hazardous contents over the required exposure period. For corrugated and paper packaging, Cobb Water Absorption testing confirms moisture resistance under the conditions specified in distribution requirements. TEN-E’s 40+ chambers and Veriteq/Vaisala data loggers provide the controlled, monitored test environment that accredited environmental testing requires.
Who Is Environmental Package Testing For?
Medical Device
Medical device manufacturers use accelerated aging to validate sterile barrier shelf life for FDA submissions.
Pharmaceutical
Pharmaceutical companies rely on accelerated aging and conditioning data to support shelf life and stability claims.
Chemical / Industrial
Chemical and industrial shippers use ESCR and compatibility testing to prove plastic containers hold up against their contents.
Accreditations That Apply

Frequently Asked Questions
Accelerated aging uses elevated temperature and humidity conditions to compress the aging process, allowing manufacturers to project packaging shelf life without waiting in real time for that period to elapse. The method is defined in ASTM F1980 and applies a calculation based on the Arrhenius equation to convert the accelerated test duration into an equivalent real-time shelf life period. Accelerated aging results support expiration date claims on product labels and are required documentation for FDA submissions on sterile medical devices.
Environmental Stress Crack Resistance (ESCR) testing evaluates whether plastic packaging containers crack or fail when subjected to chemical exposure and mechanical stress simultaneously. ESCR failure occurs when a plastic container contacts a surfactant or chemical agent that accelerates cracking under stress, a failure mode that standard mechanical testing does not capture. TEN-E performs ESCR testing on plastic tight-head drums to ASTM D5571, open-head pails to ASTM D1975, and blow-molded polyethylene containers to ASTM D2561.
TEN-E operates 40+ environmental chambers across a temperature range of -70°C to 125°C, with high humidity capability for conditioning, aging, and humidity exposure tests. Veriteq/Vaisala data loggers monitor and record chamber conditions throughout testing, providing the documented environmental data that accredited test reports require.

Yes. Pre-test conditioning establishes the moisture content and material properties of packaging before mechanical or performance testing begins. ASTM D4332 and ISO 2233 specify the temperature and humidity conditions for conditioning packaging materials, and conditioning protocols are built into many ISTA, ASTM, and ISO test sequences. Results from unconditioned samples may not reflect how packaging performs in the temperature and humidity conditions it will actually encounter. Conditioning at TEN-E is performed in the same accredited lab environment as subsequent mechanical testing, maintaining sample integrity throughout the full test program.
