The present invention relates to film layers and compositions having improved hot tack properties. The compositions comprise at least one ethylene / α-olefin interpolymer, wherein the ethylene / α-olefin interpolymer may have, for example, a Mw / Mn from about 1.7 to about 3.5, at least one melting point, Tm, in degrees Celsius, and a density, d, in grams / cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship:Tm>−2002.9+4538.5(d)−2422.2(d)2.

A flexible material for a flexible container can include a first laminate and a second laminate joined to at least a portion of the first laminate by at least one seal. The first laminate can include a first gas barrier layer disposed between first and second sealable layers, wherein the first and second sealable layers define opposed exterior layers of the first laminate. The second laminate can include a third sealable layer defining an exterior layer of the second laminate, and a second gas barrier layer. The at least one seal joins a portion of the third sealable layer to at least a portion of the second sealable layer.

An embodiment of the present invention is a sleeve, which facilitates the gripping of, and insulates the hand from, a hot or cold container. The sleeve comprises of sheet foam of a thick, opaque, plastic material that is suitable for snuggly fitting over the exterior surface of a container while permitting any pre-printed indicia on the sheet foam to be visible there through. The sleeve is opaque enough to cover any printing on the container itself. The foam is also available in a variety of forms such as anti-static, laminated, expanded and high or low density which provide different degrees of protection. Different density plastic foam and film material is used to achieve the opaque, thick, gripping and insulating effect for use with a variety of containers.

This invention relates to blends of linear low density polyethylene copolymers with other linear low density polyethylenes or very low density, low density, medium density, high density, and differentiated polyethylenes. The invention also includes articles produced from the linear low density polyethylene and polyethylene blends described.

The present invention relates to a process for detecting a leak in a package. The process comprises preparing a package by covering at least a portion of an O2-sensitive product with a multilayer film comprising (i) a leak-indicator layer in which a O2-sensitive indicator is present throughout the leak-indicator layer; and (ii) an O2-barrier layer outward of the leak-indicator layer. A low O2-environment is provided within the package. The leak-indicator layer is then illuminated with light containing a wavelength absorbed by the O2-sensitive indicator, so that the O2-sensitive indicator produces an emission of radiation in an amount inversely proportional to a level of O2 present with the O2-sensitive indicator. Then the multilayer film is scanned while the O2-sensitive indicator is emitting radiation, the scanning being carried out by sensing and comparing the amount of radiation emitted from at least two different regions of the multilayer film.

The present invention describes a multilayer film suitable for use in packaging applications comprising at least a polymeric first layer having a first surface and an opposing second surface wherein the polymeric first layer comprises a heat-sealable, water-insoluble polyester; a polymeric second layer having a first surface and an opposing second surface and comprising a pressure-sensitive adhesive, wherein the second surface of the polymeric second layer is in contact with the first surface of the polymeric first layer and forms a peelable / resealable bond therebetween; and a third layer in contact with the first surface of the polymeric second layer.

A laminated lidstock includes a substrate film, a support web; a pressure sensitive adhesive disposed between the substrate and support webs, and covering the substrate film and support web except for a clear area disposed near one end of the laminated lidstock; a first die cut disposed in the substrate film; a second die cut disposed in the support web; a pull tab; and a tamper evidence device including an end portion of the support web, defined by a first end, a first side edge, and a second side edge of the package made from the laminated lidstock, and the second die cut, capable of indicating tampering of the package upon removal of the tamper evidence device from the support web; wherein at least one of the substrate film and the support web carries a registration device.

In preferred embodiments methods and apparatuses can produce articles that have formable material. The articles may be mono and multilayer. The articles can be formed by various methods.

A flexible container is provided for the storage and administration of medical solutions. The container incorporates a transparent front sheet made from a planar layer of a polymer and an opposing rear sheet. The rear sheet is made from a planar laminate layer. The front and rear sheets are sealed together along a common peripheral edge to form a volume enclosure. The volume enclosure is constructed of materials having high oxygen and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front and rear sheets outwardly and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments, separated by peelable seals, for containing a diluent and a medicament. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient.
