Services Offered
With the development of modern logistics and the packaging industry, packaging stacking stress testing has become an essential test. GRGTEST stacking stress testing simulates the pressure and vibration experienced by goods during transportation and storage, thereby evaluating the reliability and durability of packaging materials and stacking structures.
Scope of Services
Storage pallets or packaging materials, cartons, etc. for transportation

Test Items
1. Static Stacking Test
The static stacking test refers to stacking a certain number of packages or goods to a specified height within a fixed time period, without additional vibration or shock during the test. 1. **Stacking Test:** After the test, the collapse of the stack and the extent of damage to the packaging materials can be checked.
2. Dynamic Stacking Test
Dynamic stacking test involves stacking a certain number of boxes or goods to a specified height within a certain time period, simulating vibrations and shocks during transportation. After the test, the collapse of the stack and the extent of damage to the packaging materials can be checked.
3. Vibration Test
This involves applying vibrations of different frequencies and intensities to stacked boxes or goods during simulated transportation to test the stability and reliability of the packaging materials and stacking structure. Vibration tests are typically divided into low-frequency vibration and high-frequency vibration tests.
4. Temperature Test
Temperature test involves stacking a certain number of boxes or goods to a specified height within a certain time period, while controlling the ambient temperature. After the test, the collapse of the stack, the extent of damage to the packaging materials, and the changes in packaging materials and goods at different temperatures can be checked.
Relevant Qualifications
CNAS Accredited, CMA Accredited
Testing Cycle
Typical 3-5 working days
Service Background
The length of storage time and different temperature and humidity conditions affect the compressive strength of cardboard boxes. With prolonged storage, cardboard boxes will experience creep, leading to a decrease in strength. Excessive load can cause significant deformation, forcing the contents to bear direct external pressure. Over time, this can affect the product's performance and even cause damage.
