Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.

The invention pertains to an improved PVDC composition including certain dienophiles qualified for food contact, which possess an optimized balance of effectiveness in preventing discoloration upon exposure to radiation, with no negative impact on the barrier properties, in particular sorbate esters of formula (I), wherein R.sub.1 is a C.sub.1-C.sub.12 hydrocarbon group, preferably a C.sub.1-C.sub.6 alkyl group, to layers made therefrom, to multi-layer assemblies comprising the same, and to the use of said assemblies for packaging, in particular for packaging foodstuffs. ##STR00001##

Systems and methods for joining blade components of a rotor blade are provided. A method includes positioning a first blade component and a second blade component such that a joint location of the first blade component and a joint location of the second blade component are proximate each other. The method further includes applying a force to an outer surface of the second blade component and an opposing force to an inner surface of the second blade component. The force and opposing force maintain an aerodynamic contour of the second blade component. The method further includes connecting the joint location of the first blade component and the joint location of the second blade component together.

To provide a multilayer film that enables easy opening of a packaging material manufactured by deep draw forming. A multilayer film for deep draw forming, including: a vinylidene chloride copolymer resin layer as a middle layer; a crosslinked olefin resin layer as a first surface layer; and an ethylene/vinyl acetate copolymer resin layer as a second surface layer; where the ethylene/vinyl acetate copolymer resin layer is further provided either at least between the vinylidene chloride copolymer resin layer as the middle layer and crosslinked olefin resin layer as the first surface layer, or between the vinylidene chloride copolymer resin layer as the middle layer and ethylene/vinyl acetate copolymer resin layer as the second surface layer.

Medicated starch-based powder formulations are packaged to ensure the medication remains stable for a desired shelf life. The medicated starch-based powder formulation may be packaged in a sealed container so as to maintain medicament functionality for at least one year. The container may be fabricated and/or lined with a low permeability coefficient and sealed with a foil heat induction seal liner. The container may be treated with a media to alter the surface properties of the container to increase the integrity of the container. The medicated starch-based powder formulation may include cornstarch and menthol.

A method is described for making a retort container having one or two metal ends. A heat-sealable material is present on one or both of the container side wall and the/each metal end. The/each metal end is seamed onto the container body, and the resulting container assembly is conveyed on a conveyor adjacent to an induction sealing head and then adjacent to a cooling device. A pressure belt engages the upper end of the container assembly to keep the metal end from coming off the container body during the induction heating and cooling processes.
