① Formulate and implement a variety of standards related to mechanical packaging, such as external dimensions, quality of packaging materials, strength of packaging boxes, inspection methods, etc. ② I

First, the density is small and the specific strength is high, and a higher packaging yield can be obtained, that is, the packaging volume or packaging area per unit mass. Second, most plastics have g

Plastics can be divided into two categories according to their own properties: thermoplastics that can be melt-molded repeatedly and can basically maintain their characteristics and thermosetting plas
