Description

Technical Field

[0001] The utility model relates to the technical field of gift packaging, in particular to a PVC packaging box with an adjustable internal space. Background Technique

[0002] PVC is a widely used plastic material with various properties and application fields. It is a high molecular compound polymerized from vinyl chloride monomers, having good acid and alkali resistance, corrosion resistance, aging resistance, long service life, not easy to burn and having self-extinguishing properties. Moreover, its hardness can be adjusted by adding plasticizers, ranging from hard to soft. However, compared with other plastic materials, it has a higher density, heavier weight and is prone to deformation at high temperatures, and its use temperature does not exceed 70 degrees. Nevertheless, it is still applied in various fields.

[0003] PVC materials can be applied in the construction industry, medical industry and packaging industry. In the construction industry, PVC pipes are widely used in up and down water pipes, drain pipes and wire pipes due to their advantages of corrosion resistance, pressure resistance and long service life. In the medical industry, they are non-toxic and resistant to disinfectants.
