Abstract: A lighter-than-air holographic envelope such as a balloon decorated with a holographic pattern and having long float life (one week or longer) comprises a metal layer, an embossable layer, and a polymeric gas barrier of polyvinyl alcohol/polyvinyl amine copolymer crosslinked with citric acid and an optional additional crosslinking agent such as epichlorohydrin and a heat-seal layer.

Abstract: A composite barrier film has a base layer of polyester or polyolefin with a barrier layer modified polyvinyl amine (mPVA). The mPVA is polyvinyl alcohol/polyvinyl amine copolymer crosslinked with citric acid and an optional additional crosslinking agent such as epichlorohydrin. The barrier layer can be applied by deposition of a reactive aqueous solution onto the base layer, heating and drying to remove water and crosslink the reactants. Excellent barrier properties of the film are obtained by applying and crosslinking the barrier layer during the transverse stretching steps of a biaxial oriented polymer film continuous fabrication process. Superior barrier properties are achieved with transverse stretching by a factor of about 3-4 for polyester and 4-10 for polyolefin.

Abstract: Multi-layer films suitable as sealable or peelable sheet that can be used for closing foodstuff containers are described. These multi-layer films includes a polymeric substrate layer and a seal or a peel-seal layer. The multilayer composite film preferably includes four component layers, namely in order, a polymeric base layer for mechanical strength, a thin organic barrier layer, an ethylene polymer-based adhesive layer, and a heat seal layer including an ethylene copolymer, such as ethylene vinyl acetate copolymer. The film is useful as a peelable heat sealable lid for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals.

Abstract: A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.

Abstract: Described are stretchable and formable lighter than air balloons including a high barrier lamination. The stretchable and formable balloons stretch when overinflated instead of failing. The balloons are formed from a lamination including a polyester film with a total thickness of 4 ?m to 12 ?m including a biaxially oriented polyester core layer and at least one amorphous copolyester skin layer. The polyester film has an Elongation % in the transverse direction (TD) or machine direction (MD) of greater than 125%.

Abstract: A laminate film including a first core polylactic acid layer, a coating receiving-layer of polylactic acid, and coated on one side of the coating receiving-layer with PVOH, EVOH, a blend of crosslinked EVOH/PVOH, vinyl alcohol-vinylamine (PVAm) copolymer, anionic carboxylated styrene-butadiene copolymer (SBR) emulsion, or blends thereof.

The dried coating layer can be metallized. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also optionally include a heat sealable or winding improving layer on the side opposite the coating receiving-layer of the core layer.
