Abstract
A bag comprising adhesive material applied on a ply step of the bag, a ripping-strip and a non adhesive coated area embedding the ripping-strip, providing an easy opening feature at the customer open end of the bag. The bottom of the bag comprises a folded flat bottom. The bag preferably holds an inserted inner bag. The bag has a top closure that can be folded above a customer seal in order for the inner bag to be fully independent from the outer bag after the bag is opened with the help of a ripping-strip. Upon closure of the bag, the inner bag is not trapped in an upper flap of the outer bag in order for the bag to be fully recyclable. Preferably, a mid-step is provided with the mid ply of the outer bag. The mid step stiffens and reinforces the flap.
