Patent application number | Description | Published |
20100263332 | Heat Sealing Systems and Methods, and Related Articles and Materials - A bag may be formed from a tube of high strength packaging material by forming a heat seal in the end of the tube. As part of forming the heat seal, one or more supplying apparatuses, which may be air outlets, are positioned for being in opposing face-to-face relation with, and for causing heat transfer with, at least one outer portion of the tube while a transportation system transports the tube to a nipping apparatus. | 10-21-2010 |
20100270309 | High Strength Packages and Packaging Materials - A package includes at least one closed end including a pair of opposed package panels, each face of the pair of opposed package faces including an interior side and an exterior face, at least one panel comprising a woven polymer material, wherein the interior faces of the package panels are joined to one another to define an interior joined area, the joined panels being folded towards and joined to the exterior face of the package to define a second joined area. | 10-28-2010 |
20100273017 | Hybrid Packaging Material - A packaging material includes a polymer film layer, a paper layer, a tie layer joining the paper layer and the polymer film layer, and a pair of opposed sides, each comprising a heat sealable material. The heat sealable material of the second side comprises a blend of linear low density polyethylene, low density polyethylene, and ethylene/methacrylic acid copolymer. | 10-28-2010 |
20100273377 | High Strength Packages and Packaging Materials - A packaging material comprises a substrate comprising a woven polymer, a first facing system joined to a first side of the substrate, and a second facing system joined to a second side of the substrate. The first facing system includes an outermost surface defining a first side of the packaging material, and the second facing system includes an outermost surface defining a second side of the packaging material. At least one of the first side and the second side of the packaging material is heat sealable. | 10-28-2010 |
20110052106 | Reinforced Bag - A bag has a reinforcement that is configured in a predetermined manner for reinforcing at least a portion of the bag. One or more predetermined areas of the bag may be reinforced. The bag may have one or more layers, and may be reinforced by placing and affixing reinforcing media in selected areas. The nature of the reinforcing media—its dimensions and structural properties—may be selected with respect to targeted uses of the bag. The bag may be subjected to one or more types of potentially failure-causing strain (e.g. bending, twisting, puncture, tensile, compression) during the useful life of the bag. For example, the bag may be stressed during filling the bag with product, top sealing, conveying by hand or machine, loading and stacking, transportation, storage, selling and final use by the consumer. | 03-03-2011 |
20110186210 | Heat Sealable Packaging Material with Improved Hot Tack - A packaging material includes a substrate and a heat seal layer. The heat seal layer comprises polyvinylidene chloride. The packaging material includes at least about 8 wt % moisture for increasing the hot tack of a seal formed between a first portion of the heat seal layer and a second portion of the heat seal layer relative to a packaging material with less than about 8 wt % moisture. If desired, the packaging material including the at least about 8 wt % moisture may be formed into a roll. | 08-04-2011 |
20140031186 | Reinforced Bag - A bag has a reinforcement that is configured in a predetermined manner for reinforcing at least a portion of the bag. One or more predetermined areas of the bag may be reinforced. The bag may have one or more layers, and may be reinforced by placing and affixing reinforcing media in selected areas. The nature of the reinforcing media—its dimensions and structural properties—may be selected with respect to targeted uses of the bag. The bag may be subjected to one or more types of potentially failure-causing strain (e.g. bending, twisting, puncture, tensile, compression) during the useful life of the bag. For example, the bag may be stressed during filling the bag with product, top sealing, conveying by hand or machine, loading and stacking, transportation, storage, selling and final use by the consumer. | 01-30-2014 |
20140113790 | Heat Sealable Packaging Material with Improved Hot Tack - A method of forming a package includes depositing polyvinylidene chloride on a substrate, wherein the substrate comprises paper, drying the polyvinylidene chloride on the substrate to form a packaging material including less than 5 wt % water, applying water to the packaging material so that the packaging material includes at least about 8 wt % water, and bringing a first portion of the polyvinylidene chloride of the packaging material into contact with a second portion of the polyvinylidene chloride of the packaging material in the presence of heat to form a seal. The at least about 8 wt % water is operative for increasing a hot tack of the seal relative to the packaging material including less than 5 wt % water. | 04-24-2014 |
20140338823 | Heat Sealing Systems And Methods, And Related Articles And Materials - A bag may be formed from a tube of high strength packaging material by forming a heat seal in the end of the tube.
