The dispersible non-woven article includes a web of fibers and a dried binder having a plurality of ultrasonic energy treated portions and a plurality of non-ultrasonic energy treated portions. The web of fibers has a basis weight of from about 10 gsm to about 150 gsm. The dried binder comprising a polymer having at least one functional group that is reactive with the fibers. The fibers have at least one functional group that is reactive with the polymer. The article has a cross direction wet tensile strength that is developed by the ultrasonic welding. The article is flushable.

The present invention aims to provide a double container in which an inner bag is easily pulled out from a container body. According to the present invention, provided is a double container, comprising a container body and a cap, wherein: the container body comprises an inner bag, and an outer shell arranged to cover the inner bag; the cap is attached to a mouth part of the container body; the cap comprises an inner cap, and an overcap; the inner cap is engaged with the inner bag in an axial direction; the overcap is screw-engaged with the inner cap; and the double container is configured such that the inner bag can be pulled out from the container body by pulling the overcap in the axial direction.

A method for manufacturing a compostable film for sealing a capsule for making beverages involves arranging an outer barrier layer made of a compostable material, the compostable material being paper, or regenerated cellulose, arranging a filtering element, and extruding and casting, directly onto the outer barrier layer, an inner layer, intended to come into contact with the capsule to be sealed and made of a compostable biopolymer with heat-sealing properties so that the filtering element is at least partially incorporated in the compostable biopolymer.
