International Classification:
B32B 37/00 B32B 38/04
US Classification:
156259000, 156271000
Abstract:
The present invention includes a continuous process for manufacturing packaging laminates adapted for easy tearing comprising the steps of providing a first and a second flexible web, applying a fluid adhesive to the first flexible web, drying the fluid adhesive, or optionally, curing the fluid adhesive, slitting one of the first and second flexible webs to form a plurality of parallel strips of at least of one the first and said second webs, and laminating the first and second flexible webs together thereby forming a laminate a plurality of parallel strips. The present invention also includes laminates form by this process.

Curwood, Inc. - Oshkosh WI
International Classification:
B32B 27/34
US Classification:
428474400
Abstract:
Multilayer film structures are disclosed having a first layer of polymer sealant material, a second layer comprising a frangible bond layer, and a third layer comprising an adhesive or polyolefin. The first layer comprises from about 1% to about 10% of the total thickness of the multilayer film structure, has a maximum thickness of about 0.25 mils. and has a thickness uniformity deviation of less than about 20% of the average thickness of the first layer.

US Classification:
383210
Abstract:
An easy open package adapted to be heat sealed closed and peelably reopened including a first package wall comprising an outer layer, an inner sealant layer and a tie layer disposed between and peelably bonded to either the inner layer or the outer layer and a second package wall joined about a portion of its perimeter to the first package wall and comprising at least one layer, that layer being a sealant layer having the same composition as the inner sealant layer of the first package wall and disposed adjacent thereto, the sealant layers being heat sealable together to form a bond having a bond strength greater than the bond between the tie layer and the layer to which it is peelably bonded, that bond strength being predetermined by the selection of the compositions of the adjacent layers.

Described are liners for bulk containers that are abuse resistant. The liners include at least one sidewall. The sidewall includes at least an exterior ply and an interior ply. Optionally, the sidewall may include at least one intermediate ply. One of the plies includes a first polyolefin-silicone copolymer. The adhesion between the plies is from 0 g/25.4 cm to 50 g/25.4 cm (0 g/in to 50 g/in).
Methods And Compositions For On-Demand Release Of Clo2 Gas From Uv-Activated Chlorite Ion
Compositions and methods for generating ClOgas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period, the composition is then exposed to moisture, resulting in the generation of ClOgas. Exemplary compositions include polymers in which the chlorite salt is dispersed. The polymers may be used to form films that can be used to package, e.g., food products, pharmaceutical products, medical devices, and/or laboratory devices. Upon exposure to ultraviolet light and moisture, the packaging releases controlled quantities of ClOgas, which may disinfect and/or deodorize the packaged device or product.

International Classification:
A23B 7/144 B32B 27/32 C08L 23/12
Abstract:
A multilayer produce packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.
