Abstract: A liquid pouch is comprised by a polymeric film material bag which has a front and a rear wall. The front and rear walls define a top and bottom edge and opposed side edges. A dispensing fitment is secured in an upper region of the pouch spaced from the top edge. The dispensing fitment has a rigid spout neck with a removable closure member. An attachment flange wall surrounds the spout neck and is secured to the plastic film material. The spout neck has a base formation shaped for friction fit retention in a connecting slot of a support member. The pitcher has a connecting slot formed in an upper edge thereof with the slot having a bottom retention section to receive the engageable formation in retention fit therein to retain the bag containing liquid secured thereto for dispensing the liquid through the spout neck.

Abstract: Heat-sealable thermoplastic elastomeric films comprise from approximately 35% to about 65% of an A-B-A block copolymer wherein "A" blocks are derived from polystrene or a polystrene homolog and said "B" blocks being derived from lower alkenes and from about 25% to about 55% of an ethylene vinyl acetate copolymer, the ethylene vinyl acetate copolymer comprising approximately 28% vinyl acetate. The films are heat-sealable to various substrates including polyvinyl chloride. Once sealed to the substrate, the film may be readily peeled from the substrate by the application of a low and relatively constant peel force. A method for measuring the peel strengths of the film is disclosed. The films are especially adapted to being heat-sealed to a substrate which forms, together with the substrate a package, or multiple serially connected packages.

Abstract: A starch filled, coextruded degradable polyethylene film includes a starch filled inner layer positioned between two outer layers that contain a prodegradant. The outer layers of the film, which contain no starch, enable the film to retain desirable physical properties similar to conventional polyethylene film. The prodegradant causes the outer layers of the film to degrade under appropriate conditions exposing the starch filled inner layer. The starch in the inner layer then serves as a source of nutrients for microorganisms which consume starch, leaving a porous structure that is vulnerable to oxidation, hydrolysis, direct enzyme action or combinations of these processes.
