Abstract: A layer includes polyvinyl alcohol and 20 wt % or more calcium carbonate, based on the total weight of the layer. Another layer includes polyvinyl alcohol and calcium carbonate. A container includes a body that defines an internal cavity capable of holding an article, the body including a layer including polyvinyl alcohol and 20 wt % or more of calcium carbonate, based on the total weight of the layer. Another container includes a layer including polyvinyl alcohol and calcium carbonate.

Abstract: A polymeric film bag having first and second panels that are joined to each other along a pair of opposing sides and a bottom bridging the opposing sides. Each of the first and second panels have an original width. Extending inwardly from near or at one of the pair of opposing sides is a first narrowing seal. The first narrowing seal seals the first and second panels together such that a second width of the first and second panels is created that is smaller than the original widths of the first and second panels.

Abstract: Packages with active agents are described. Generally, the disclosed packages have a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides so as to define a mouth opposite the bottom, a reclosable fastener extending along the mouth, and an active agent. The reclosable fastener includes a pair of polymeric tracks, in which each of the tracks includes a mating element and a fin portion. The mating elements are releasably engageable to each other, and each of the fin portions extends downwards from the respective mating element towards the bottom of the reclosable package. The active agent is associated with at least one of the fin portions for communication with the interior of the reclosable package.

Abstract: Packages with active agents are described. Generally, each disclosed package has a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides, a reclosable fastener extending along a mouth formed opposite the bottom, and at least one active agent. The at least one active agent is associated with at least one of the body panels and includes a freshness-extension agent to inhibit spoilage of perishable product disposed in the package, an odor management agent to reduce, mask, or neutralize odors from garbage or waste disposed in the package, or another type of agent.

Abstract: A blown-film process for making a fiber-reinforced film comprises providing and melting at least one thermoplastic resin. The at least one thermoplastic resin is extruded through an extension die to form a film bubble. A plurality of fibers is introduced inside of the film bubble. The fibers are distributed inside of the film bubble. The film bubble is collapsed after introducing the plurality of fibers so as to form a fiber-reinforced film. The fiber-reinforced film has a first thermoplastic layer, a second thermoplastic layer, and a plurality of fibers dispersed therebetween. The film may be formed in a bag.
