[0023] Specifically, the thermal insulation pad body includes a buffer insulation component, a thermal insulation core material 2 and a packaging film.

[0025] As a preferred embodiment, please refer to Figure 1-Figure 2 There are two thermal insulation pad bodies, namely a first thermal insulation pad body 11 and a second thermal insulation pad body 12.
