Express delivery bag and structural configuration thereof

Abstract

An express delivery bag includes an airbag film layer and a plastic bag film layer. The airbag film layer includes at least one airbag and a main flow runner. The main flow runner communicates with the at least one airbag, allowing air to be injected into it, thereby changing the airbag from a flat state to an inflated state. The plastic bag film layer and the airbag film layer are folded along a folding line, with the plastic bag film layer forming the outer bag and the airbag film layer forming the inner bag. The inner bag has a containing space therein and is contained within the outer bag.
