20090047395 | Multi-Compartment Package - A method for making a multi-compartment microwavable package having one or more open or closed compartments within the package, and method and apparatus for manufacturing the same, constructed by modification to existing vertical form, fill and seal packaging machines. The invention involves producing a multi-compartment bag having an internal permeable wall between compartments from a single sheet of flexible packaging film. A food product can be placed into the first compartment and steam pack can be placed into the second compartment. | 02-19-2009 |
20090061126 | Package and Multi-Layer Flexible Film Having Paper Containing Post Consumer Recycled Fiber - A multi-layer film and package with barrier properties made from a multi-layer film having one or more layers made with paper comprising post consumer reclaimed fibers is disclosed. In one aspect, the print web comprises a paper sheet made from post consumer reclaimed fibers. Unlike prior art petroleum-based films, the inventive film having PCR paper of the present invention is made from a renewable and/or recycled resource and is biodegradable. | 03-05-2009 |
20100221560 | Bio-Based In-Line High Barrier Metalized Film and Process for its Production - Bio-based high barrier metalized film such as PLA or PHA has an adhesion layer coated or co-extruded with the bio-based film and a metal oxide is disposed on the adhesion layer. The adhesion layer can be a co-extruded polyethylene terephthalate, nylon, polyglycolic acid, or ethylene vinyl alcohol. The adhesion layer can have a coating of EVOH, a nylon/EVOH blend, PVOH, PVOH/EAA mixtures, or a primer. | 09-02-2010 |
20110200796 | ENVIRONMENTALLY-FRIENDLY MULTI-LAYER FLEXIBLE FILM HAVING BARRIER PROPERTIES - A multi-layer film with barrier properties having one or more layers made from a bio-based film is disclosed. In one aspect, a multi-layer packaging film including (a) an outer layer including a bio-based film, wherein the bio-based film is polylactide, (b) an adhesive layer adjacent to the outer layer and (c) a product side layer including a metalized polyolefin having barrier properties, wherein the multi-layer packaging film is a flexible film. | 08-18-2011 |
20110200844 | COMPOSITION FOR FACILITATING ENVIRONMENTAL DEGRADATION OF A FILM - A multi-layer PLA film with barrier properties having one or more additives. In one aspect the additive can lower the glass transition temperature of the PLA to enhance the span of environments in which the PLA film can degrade. In one aspect, a plasticizer can be added to lower the glass transition temperature to facilitate degradation at lower temperatures. In one aspect, calcium carbonate can be added to a PLA film layer. | 08-18-2011 |
20130224446 | BIODEGRADABLE PACKAGE WITH SEALANT LAYER - A multi-layer packaging film comprising a bio-based layer and method for making the same. An outer layer comprising a bio-based film is adhered to a product side layer comprising a bio-based film having barrier properties. A non-compostable sealant layer is pattern applied to a portion of the product side layer. Because a portion of the bio-based product side layer is exposed, upon opening of the package the product side layer is susceptible to moisture. This allows for subsequent biodegradation or compostability of the films. In another embodiment the sealant layer comprises a water permeable material. Upon opening of the package moisture can subsequently contact the product side layer and initiate biodegradation. | 08-29-2013 |
20130251988 | COMPOSITION AND METHOD FOR MAKING A CAVITATED BIO-BASED FILM - Composition and method for making a multi-layer bio-based film having one or more cavitated layers. In one aspect, the multilayer flexible film has polylactic acid, an inorganic filler, and a cavitation stabilizer making up at least one film layer. In one aspect, the barrier web has a cavitated bio-based film layer. In another aspect, the print web has a cavitated bio-based film layer. | 09-26-2013 |
20140272304 | COMPOSITION AND METHOD FOR MAKING A FLEXIBLE PACKAGING FILM - Composition and method for making a flexible packaging film having highly loaded with at least one inorganic filler. A blown HDPE film comprising at least 50% by weight inorganic filler is oriented in the machine direction to increase yield and tensile strength, and reduce gauge variation to improve print qualities. | 09-18-2014 |
