Abstract (en)
[origin: WO2022087038A1] A web of bags includes a sheet material and a connecting material. The sheet material includes two sheets that are formed from a fiber-based material, are arranged to form a series of bags, and are connected together to form sides of the bags. Each bag is bounded by the sides where sheets are connected together and an opening. The connecting material is applied to inner surfaces of the sheets and can be activated to connect innder surfaces by the activated portions of the connecting material. The connecting material is applied to closing regions on the inner surfaces of the sheets such that the connecting material in the closing regions can be activated to close the opening.
