Abstract

The invention relates to a method for measuring the welding strength of a foaming buffer material. The method is characterized by comprising the following steps: 1) selecting a test cone; (2) mounting a measuring device; (3) determining the falling height; 4) horizontal adjustment; and 5) measuring the welding strength. The method is scientific and reasonable in design, the welding strength of the foaming buffer material can be accurately measured, the use of the foaming buffer material is guided, the measurement operation is simple, and the precision is high.

Description

technical field [0001] The invention belongs to the field of packaging testing, relates to the measurement of foamed cushioning materials, in particular to a method for measuring the welding strength of foamed cushioning materials. Background technique [0002] In the field of packaging technology, foamed cushioning materials are often used for packaging and transportation to ensure the safety of packaging. For foamed cushioning materials, the welding strength is an important indicator for judging the degree of compactness and fragility between particles. The welding strength indicates the tightness and fragility of the connection between the foam material particles. A high degree of fusion is not easy to break, and a low degree of fusion indicates that the foam material particles are easy to fall and break. [0003] For the safety of packaging and transportation, it is very necessary to measure the welding strength of foamed materials. However, at present, there is no tes...
