This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise a mixture of (A) a terpolymer prepared from a mixture comprising (i) an olefin, (ii) at least one copolymerizable comonomer comprising ethylenically unsaturated organic acids or esters, vinyl esters of saturated carboxylic acids and mixtures of two or more thereof, and (iii) carbon monoxide, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.

Antimicrobial composites, films, labelstocks and labels

This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise (A) a polymer mixture comprising a mixture of at least one styrene polymer and at least one urethane polymer, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time.

A method of making a plurality of flexible containers () comprising the steps of manufacturing a plurality of bag structures (), separately manufacturing a plurality of valves (), aligning the valves () with openings () in the bag structures (), and securing the aligned valves () to the bag structures (). Each valve () comprises a vent layer () which is pervious with respect to expected gasses and a sealed passageway is formed between the vent layer () and the container () when the valve () is secured to the bag structure ().

A double sided tape for detachably mounting a flexible printing plate to a flexographic printing press cylinder includes pressure-sensitive adhesive layers on opposed sides of a coextruded multilayer carrier having a core formed of a thermoplastic elastomer containing a uniform distribution of voids and one or more skin layers formed of film-forming thermoplastic polymer. The cellular thermoplastic elastomer is constructed to accommodate compressibility loads imposed during printing and to resist shear and tensile loads imposed during tape removal.

Fastening systems for releasably securing two components together include tab and landing members. In a first arrangement, a Z-fold tab member has combined mechanical and adhesive engagement. A second arrangement includes adjacent adhesive and cohesive contact portions. A third arrangement contoured apertures and mechanical engaging elements. A fourth arrangement includes apertures and mechanical engaging elements sized and arranged so that each aperture receives a plurality of mechanical engaging elements. A fifth arrangement includes tab and landing members that cooperate to provide a color indicia of secure adhesive engagement.

Z-fold diaper fastener

A fastening system for releasably securing a diaper provides both mechanical and adhesive or cohesive securement. Tab members comprise a facestock layer, a contact layer of adhesive or cohesive overlying at least a portion of the facestock layer, and mechanical fastening elements projecting from at least a portion of the contact layer. The facestock layer includes extensible and substantially nonextensible polymeric portions. A landing member includes complementary mechanical fastening elements and a contact surface or cohesive for engagement with the tab adhesive or cohesive. A method is also disclosed for making the fastening system.

A button attaching device for attaching a button having four holes to a layer of material includes a holder having a front end and a rear end, four rodless fastener dispensing needles projecting out from the front end of the holder and two fasteners, each having a foot at each end of an elongated filament. Each foot is removably mounted on one of the rodless fastener dispensing needles. A cover is removably mounted on the front end of the holder and includes an anvil. In use, the cover is removed from the holder and the layer of material placed on the cover over the anvil. The button is then placed over the layer of material. The holder is then pushed in the direction of the cover so that the needles and fastener feet extend through the holes in the button and through the layer of material, with the tips of the needles striking the anvil. The tension on the filaments of the fasteners causes the feet to pop out from the needles. The needles are then withdrawn leaving the button secured to the layer of material by the fasteners.

Button attaching device

A button attaching device includes a top member and a bottom member which are hingedly connected together, the bottom member including an anvil. The button attaching device further includes a needle block assembly mounted on the top member. The needle block assembly includes a block of material, a pair of rodless fastener dispensing needles and a fastener. The fastener is shaped to include a foot formed at each end of a filament which can be removably mounted on one of the pair of rodless fastener dispensing needles. In one embodiment of the present invention, the needle block assembly is removably mounted on the top member and is sized and shaped so as to fit within a needle block assembly storage compartment formed in the bottom member. In another embodiment of the present invention, a plurality of needle block assemblies are interconnected to form a needle block carousel which is rotably mounted within a hollowed portion formed in the top member. The carousel comprises a mounting block rotably mounted on the top member, each of the plurality of needle block assemblies being spring mounted on the mounting block.

A method of adhesively securing first and second members together by sliding movement of the members along an interface where the members are to be joined by an adhesive layer having opposed normally tacky and normally sliding-movement-resistant sides includes the step of applying a liquid to an exposed side of the adhesive side to reduce its tackiness. After sliding assembly of the members, the liquid is transmitted from the side of the adhesive to the interior of the adhesive to enable tack increase at the exposed adhesive side and adhering of the members together. The adhesive includes a moisture absorbing component to enable liquid accumulation at the exposed side and subsequent transmission to the adhesive interior.
