摘要： A recloseable multibag freezer bag including an inner liner bag and an outer support bag. The inner liner bag is a thermoplastic with a thickness of less than 2 mil and a specified secant modulus, has a mouth through which the interior of the inner liner bag is accessible, and is joined by a mouth seal to the throat of the support bag along the entire length of the mouth of the liner bag substantially enclosing an air space between facing walls of the inner liner bag and outer support bag. The outer support bag is a thermoplastic, and has a mouth and a throat. A recloseable mouth seal is affixed to its mouth to provide recloseable access to the interior of the liner bag through the outer bag while maintaining the enclosed air space between the inner and outer bags.

摘要： A dispensing package for dispensing discrete portions of a vaporizable material in the form of prewetted absorbent pads, wherein the dispensing package broadly comprises a container and a plurality of such absorbent pads. The absorbent pads are closely stacked within the container, and generally comprise an absorbent pad portion with a flexible film backing which is resistant to permeation of the vaporizable material therethrough, and a collapsible tab- or ring-like structure joined to the backing opposite the absorbent pad portion. In other embodiments, the absorbent pad portion is preferably sub-divided into sub-portions having different fluid absorbing characteristics, which sub-portions are separated by the same flexible film as used in the backing, and less than all of the sub-portions are initially prewetted with the vaporizable material or are prewetted with different materials.

摘要： A method and apparatus for producing a plastic film having strips of an adhering material embedded in each surface of the film, which film may have an anti-block agent incorporated therein, and a composite plastic film so produced is provided which includes initially providing a first stream of heat plastified extrudable thermoplastic film material to a cast film die. The cast film die has two opposing die lips with each die lip having a plurality of spaced strip channels. The strip channels of one die lip are laterally offset from the strip channels of the second die lip. A heat plastified extrudable adhering material is introduced into the plastified film material from the strip channels and then the composite body of materials is forced from the die lips of the cast film die and cooled to form the plastic film.
