Abstract: A continuous sealing device includes: a first roller, having a first circumference, where the first circumference includes a first heat sealing segment; a first heating member, located at the first heat sealing segment, where when the first roller rotates, the first heating member bonds film sheets in a heat sealing manner to form a first bonding segment; a second roller, having a second circumference, the second circumference includes a second heat sealing segment; and a second heating member, located at the second heat sealing segment, where when the second roller rotates, the second heating member bonds the film sheets in a heat sealing manner to form a second bonding segment, and the first bonding segment and the second bonding segment are connected to form an uninterrupted heat sealing wire on the film sheets.

Abstract: A packing bag with a cushioning function includes: a first cushioning air cylinder portion, constituted by air cylinders; a second cushioning air cylinder portion, constituted by air cylinders, and coupled to the first cushioning air cylinder portion to form an accepting space; and a binding belt, coupled to the first cushioning air cylinder portion and/or the second cushioning air cylinder portion, and used for sealing an opening of the accepting space. The first cushioning air cylinder portion and second air cylinder portion constituted by the air cylinders can perform the cushioning protection of an object effectively, solving the problem of the shock-absorption capability insufficiency of the conventional small air sacs, solving the problem of the conventional small air sacs being insufficient in shock-absorption capability. In addition, the binding belt not only allows a label to be attached thereon, but also avoids the air cylinder being pierced through.
