A radiographic film package for non-destructive testing, comprising a radiographic film sheet, an intensifying screen with a layer of lead bonded to a paper foil, and a vacuum heat-sealed wrapper with a layer of aluminium and a heat-sealable easy-peelable thermoplastic layer.
This application is a continuation of application Ser. No. 428,807, filed 9/30/82, which is also a continuation of application Ser. No. 246,107, filed 3/20/81, all now abandoned.
A radiographic film package for non-destructive testing purposes has been developed, comprising a radiographic film sheet which is composed of a film support coated at both sides with one or more silver halide emulsion layer(s) and one or more non-light-sensitive protective antistress coating(s) thereover, and a wrapper around said film sheet which is light-opaque and air-tight, and which comprises a heat-sealable thermoplastic layer at the inner side of the wrapper, a transparent polymer layer at the outer side of the wrapper and a layer of aluminum located between said transparent polymer layer and said heat-sealable thermoplastic layer, and wherein at least one antistatic layer coating is provided between the said thermoplastic layer of said wrapper and the emulsion layers of said film sheet.
A packed phosphor screen or panel consisting of at least one flat square or rectangular screen or panel, optionally packed apart in a wrapper foil, and a sealed package, wherein said package is layered in form of an asymmetrical barrier layer foil, said foil comprising an inner flexible thermoplastic polymer layer and an outer polymer layer in adhesive contact with an aluminum layer situated inbetween said inner flexible thermoplastic polymer layer and said outer polymer layer, wherein said foil is characterized by adhesive forces, between said outer polymer layer and said aluminum layer, of more than 2.5 N/mm.sup.2 following DIN 53 357, by a permeation to water vapor of less than 0.01 g per sq.m. in an environment having a temperature of 23.degree. C. and a relative humidity of 75% RV for 24 hours following DIN 53 122, and by a permeation of less than 0.01 cm.sup.3 per sq.m. per 24 hours and per bar for each of oxygen, carbon dioxide and nitrogen following DIN 53 380 (ISO 2556, ASTM D 1434).
A film package including sheets of imaging media or film sandwiched between upper and lower stiffeners and enclosed by an envelope. Adhesive strips secure the stiffeners together at overlapping tabs formed on opposite sides of the stiffeners. The stiffeners with the film sheets are removed from the envelope by opening one side of the envelope. The adhesive strips also have tear strips for allowing removal of the upper stiffener after the package has been placed in a drawer of a printer with the aid of offset tabs on the stiffeners which indicate and assure proper orientation. A notch in the corner of the lower stiffener allows a signal to be passed to indicate whether the upper stiffener has been removed. The lower stiffener is also apertured to receive a signal for indicating whether any film sheets remain on the stiffener while in the drawer of the printer.
An image media assembly comprising: a doner element, a receptor element, and means for maintaining the elements in a predetermined position wherein one element overlies the other, said means including a vacuum present between the elements.
An image media assembly comprising: a donor element, a receptor element, and means for maintaining at least the elements in a predetermined position wherein one element overlies the element, said means including a vacuum present between the elements.
