Abstract: A flexible, stackable, reclosable container for storing a quantity of products comprising a plurality of walls defined by a first sheet and a second sheet attached to at least a portion of the first sheet. The second sheet extends over at least three of the walls. The opposing container walls each have a sealed portion and one or more tucks, the tucks comprising a portion of the first sheet tucked toward the interior volume. A portion of the second sheet defines a reclosable feature located over an opening for reclosing the container. The second sheet includes a line of reduced strength at or adjacent at least a boundary adjacent the tucks and disposed between the opposing container walls each having the sealed portion and an adjacent container wall. The second sheet can include a hinge about which the reclosable feature pivots from closed position to open position.

Abstract: A high barrier film and method of forming a high barrier film. The film includes a biopolymer and metallization layers. A primer layer is applied to one of the metallization layer and the biopolymer layer and a nanocomposite barrier coating is disposed between the primer layer and the metallization layer. The film includes a second biopolymer layer and an adhesive layer, the adhesive layer disposed between the second biopolymer layer and the metallization layer, where the second biopolymer layer is adhered to at least one of the biopolymer layer, the metallization layer, the primer layer and the nanocomposite layer.

Abstract: A biopolymer blown film extrusion system comprising an extruder receiving polymer pellets and at least two additives, and generating a molten mass having at least one layer; a die receiving the molten extrudates and generating a bubble having at least one layer from a die orifice; an internal bubble blower operably connected to maintain air inside the bubble; a bubble collapsing frame receiving the bubble and generating a biopolymer film having at least one layer, the film having a selected elongation at break of 180% or more in one direction and heat sealing at 195° F. or less; a nip roller operably connected to draw the biopolymer film from the bubble collapsing frame; a turning bar operably connected to change a travel angle of the biopolymer film; and a travel roller operably connected to direct travel of the biopolymer film.

Abstract: A system and method for forming a biopolymer roll stock for a biopolymer form-fill-sealed package, the biopolymer roll stock includes at least one biopolymer resin; and at least one additive, the additive including at least one impact modifier between 5-50 weight % of the total weight of the additive; and at least one polymer color concentrate between 5-50 weight % of the total weight of the additive, whereby the biopolymer roll stock has a predetermined thickness and impact resistance.

Abstract: Embodiments relate to an additive for a biopolymer article, a method for forming the additive and biopolymer articles and sheeting containing or formed using the additive. The additive includes at least one impact modifier between 10-90 weight % of the total weight of the additive; at least one polymer color concentrate between 5-50 weight % of the total weight of the additive; and at least one carrier resin between 5-50 weight % of the total weight of the additive.

Abstract: A multi-layer freezable/microwaveable film having both low temperature resistance and high temperature resistant to withstand subzero freezer storage temperatures and microwave cooking temperatures. The freezable/microwaveable film includes a three-layer coextruded film having a polypropylene/alpha-olefin copolymer inner, heat sealable layer, an adjacent polypropylene or high density polyethylene core layer, and an outer polyethylene skin layer adjacent the core layer opposite the heat sealable layer, and further includes an outer protective layer laminated to the outer skin layer.

Abstract: A film formed from biopolymer lamination for thermal lamination to a rigid biopolymer structure including a polymer layer; a biopolymer layer; and an adhesive layer joining the polymer layer to the biopolymer layer. The biopolymer layer is thermally adherable to the rigid biopolymer structure.

Abstract: A printed thermoplastic film having a radiation-curable overprint coating is disclosed. The thermoplastic film is printed with an ink system that comprises a polyvinyl butyral carrier resin, a pigment dispersed in the carrier resin, a solvent, a plasticizer, and a coupling agent. The polyvinyl butyral based ink system provides better adhesion to the thermoplastic film than conventional nitrocellulose-based inks when used in conjunction with the radiation-curable overprint coating.
