Abstract:
The present invention relates to a method of attaching an active film (5) onto a flexible package comprising the steps of heating a foil (2); applying an active film (5) to the foil (2); and applying sufficient pressure to the active film (5) and foil (2) combination and sufficient heat to the foil (2) so that active film (5) adheres to the foil (2). In one example, the active film (5) comprises two components and wherein the two components are an active agent and a polymer. In another example, the active agent is an absorbing material.
Abstract:
Film structures, packages and methods of making the same are provided wherein the film structures have a desiccant material incorporated into a sealant layer (110) of the film structures and further wherein the sealant layer (110) of the film structures comprise a material for making a peelable seal when the film structures are heat sealed to other film structures. The film structure is utilized for a package to hold a product (206) that may be sensitive to the presence of moisture. The product may preferably be pharmaceutical or nutriceutical products, although any moisture-sensitive product is contemplated by the present invention.
Abstract:
The present invention relates to the non-invasive use of a luminescent compound to detect and measure concentrations of oxygen dissolved in a rigid container, especially a bottle, a tray, a carton, a lidstock associated with a tray, a stand up pouch, or apaperboard container. The measurement is made independent of the oxygen concentration of the surrounding atmosphere. The inventio n is especially useful as a quality assurance check to verify oxygen scavenger activation during the assembly of bottled products,and modified atmosphere and vacuum packages. The method accordin g to the invention is faster measuring oxygen concentration within the headspace of an assembled package.
Abstract:
Herein is disclosed an oxygen scavenging composition, comprising (i) an oxygen scavenging polymer comprising structure I: wherein -R- is selected from the group consisting of C 1 -C 24 alkyl, C 1 -C 24 substituted alkyl, C 6 -C 24 aryl, and C 6 -C 24 substituted aryl; -Ar- is selected from the group consisting of C 6 -C 24 aryl and C 6 -C 24 substituted aryl; and -X- is selected from the group consisting of null and -C(=O)-; (ii) a transition metal oxidation catalyst; and (iii) an energy-absorbing compound selected from the group consisting of microwave reactive materials and photoinitiators having a wavelength of maximum absorption of electromagnetic radiation from about 200 nm to about 750 nm. The oxygen scavenging composition can be used to form an oxygen barrier packaging article.
Abstract:
A method and package (22) for storing a pressurized container (34) which is filled with a drug formulation at a predetermined pressure. The drug formulation includes a mixture of a drug and a propellant. The package which encloses the pressurized container substantially prevents ingression of water vapor and particulate matter into the package while permitting egression of the propellant which may leak from the pressurized container.
Abstract:
Oxygen barrier polyamide compositions exhibiting high oxygen scavenging capability suitable for extended shelf-life, packaging applications. Thus a polyamide composition comprises a polyamide homopolymer, copolymer, or blends thereof, and at least one polyamide reactive, oxidizable polydiene or oxidizable polyether. The polyamide products are particularly suited to making barrier packaging articles such as monolayer or multi-layer films, sheets, thermoformed containers and coinjection/coextrusion blow molded bottles comprising PET, polyolefin or polycarbonate as structural layers. Such articles are useful in a variety of oxygen-sensitive food, beverage, pharmaceutical and health care product packaging applications.
Abstract:
A specially-suited package comprising: a container (20) having at least one compartment for storing a liquid (24); a dispensing opening (30) in liquid communication with said at least one compartment; a closure for sealing the opening; and a plastic member impregnated with a perfume composition wherein the plastic member (36) is in communication with said compartment so that upon being released from the plastic member the perfume composition effectively suppresses malodors, particularly those malodors emanating from nitrogenous compounds.
Abstract:
A method of extending the shelf-life of fresh foods, such as meat, poultry, seafood, vegetables and fruit, uses a sheet comprising a film with a layer of adhesive and a curing or marinating agent attached to the film by the adhesive. The food is sealed in the sheet, with the curing or marinating agent in intimate contact with the food, and the package is maintained at a temperature of about 0 DEG C until the food is substantially cured or marinated.
