ABSTRACT:
A valve bag has a sleeve that includes a butt seam formed by abutting opposed edges of a paper sheet and securing the abutting edges. A strip of tape may be used to secure the abutting edges. The interior surface of the sleeve and the tape are both constructed from a sealable material. A tight seal is achieved when the sleeve is sealed.
