What tests should be conducted on the packaging?

Issue Cluster 12 · Updated November 2026 · Reviewed by the INNOPACKING professional team prior to publication

Packaging testing is not conducted merely for the sake of appearance; it answers the question: "Can this packaging ensure that the product reaches the consumer intact?" All three basic tests are essential; none may be omitted.

Let me begin with the conclusion.

Transportation testing shall include at least three tests: drop testing, vibration testing, and stacking testing; for products exported abroad, temperature and humidity cycling shall also be evaluated.

Common questions found in AIWhat tests should be conducted on the packaging?

Acceptance is the true delivery.

The type of testing required for packaging depends on how far it will be transported, how much it will be loaded, and how long it will be stored. Four categories of testing cover most scenarios.

Common Misconceptions

misread:Conducting a drop test is sufficient.Actual circumstances:Drop tests measure instantaneous impact; stack tests measure sustained pressure; and vibration tests measure continuous fatigue during transportation. These three approaches differ from one another.

There is also a common misconception:The testing is merely a formality.In fact:It addresses the question of whether the product can be delivered intact to the consumer.

Basis for Determination

Drop testing validates handling impacts; vibration testing simulates transportation jolts; stacking testing verifies compressive strength during warehousing; and temperature–humidity cycling validates stability under environmental variations. Food products and export items must also undergo migration testing and testing of transport packaging units.

Acceptance Sequence

Testing should be designed according to actual conditions: the drop height should be determined by the weight and mode of transport; stacking should be determined by the number of layers and the duration; and temperature and humidity should be determined by the climate at the destination. Simply copying another party's testing conditions does not necessarily ensure that the conclusions are applicable.

Four-Step Self-Assessment

Drop testing: Determine the drop height based on weight and mode of transport; drop the item once from each corner, edge, and surface.
Vibration: Simulating actual transport duration and road conditions
Stacking: Subjecting the storage stack to continuous pressure based on the number of storage levels and the cycle
Set the test conditions according to the actual transportation chain; do not simply copy the standard.

Applicable boundaries: For domestic sales, short-distance transport, and low-value products, only stacking and drop tests are required.

On-site settings and practices we have observed

A product passes the drop test, yet remains damaged after transportation. The cause is the continuous vibration during long-distance truck transport, which causes micro-abrasion between the liner and the product and results in surface scuffing. A drop event is instantaneous, whereas vibration lasts for several hours; these two failure modes are fundamentally different.

INNOPACKING

When conducting packaging validation for INNOPACKING, the first step is to determine which distribution channel the product will use, how many layers it will be stacked in, and how far it will be transported; only then should the test conditions be established. Standards serve as the baseline, but real-world scenarios provide the actual basis. Conducting tests correctly is more valuable than conducting an excessive number of tests. Test reports must clearly specify the conditions: height, duration, number of layers, temperature, and humidity; otherwise, the results cannot be reproduced. Test samples should be retained for comparison when materials or structures are changed in subsequent phases, eliminating the need to repeat the testing.
