Packaging and transportation test manufacturers believe that packaging is to reduce damage to products during transportation and circulation, ensure product safety, facilitate storage, transportation, loading and unloading, and speed up delivery and inspection. People regard transportation, storage and transportation as the main purpose of packaging. There are various modes and shapes of transportation, different materials and textures, and different levels of packaging, which leads to the diversity of transportation packaging, such as paper packaging, metal packaging, wooden packaging, plastic packaging and so on. Its main function is to protect the goods, prevent the goods from being damaged during storage and transportation, and avoid the possible impact of various external conditions on the goods during transportation to a greater extent, so as to facilitate inspection, inventory and distribution. Since the purpose of transportation and packaging is to protect the safety of the product, why should the packaged product be tested?

　　1. Packaging and transportation test The manufacturer believes that the purpose of packaging is to protect the product from reaching its destination safely. However, during the handling process, it will be subject to shocks such as falling, sliding on slopes, vibrations, etc., which will affect the quality of the goods. Therefore, pre-assessing and assuring the packaging quality in the shipping environment is to protect the product from the foreseeable factors.

　　2. Packaging and transportation parts testing The manufacturer believes that testing and improving the safety performance of product transportation and packaging can prevent or reduce product losses during transportation and loading and unloading, and maintain the direct interests of the company.

　　Therefore, it is necessary to conduct a series of reliability tests on packaged and transported products. Let's see how the packaging and shipping testing works.

　　1. Clarified the requirements of the "impact table": the packaging and transportation parts test manufacturer believes that the impact table should be flat and rigid; when any 10mm * 10mm area bears a 10kg static load, the deformation must not exceed 0.1mm between any two points on the impact table The difference in horizontal height between any two points shall not exceed 2mm. For samples whose contact size exceeds 1000mm with the impact table, the maximum deviation of the horizontal height between any two points shall not exceed 5mm. The mass of the impact table should be greater than 50 times the mass of the specimen and large enough to ensure that the specimen falls completely on its surface.

　　2. In the surface drop test, edge drop test, angle drop test and free drop test, the requirement that "the sample should be prevented from tipping over during the fall" has been added.

　　3. The free fall test is added to the test of packaged and transported parts. The sample is lifted above the impact table, and the sample can be released by cutting the rope, electromagnetic control and other methods to make it fall freely; a special drop tester can also be used in accordance with GB /T 4857.5-1992 "Packaging and Transport Package Drop Test Method" for testing.

　　4. An inclination test is added to the test of packaged and transported parts. Use chains, slings and other similar tools to properly fix the sample to prevent the sample from tipping over during the test. Unless otherwise specified, tilt the specimen 22° from the vertical position, observe its movement (tilt or return to the original position), and then gently return the specimen to its original position. Repeat the above operation in all possible unstable orientations.
