  • In-mold label film and method
    Patent number: 5733615
    Abstract: An oriented polymeric in-mold label film comprises a hot-stretched, annealed, linerless self-wound film lamina and has a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat may be included only in the charge for the base layer which includes the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from the film may be handled at high speeds while maintaining accurate registration and dimensional and positional integrity even in the absence of any reinforcing backing, yet the labels perform well on deformable containers such as shampoo bottles.

  • Composite for controlling oxygen flux into thermal cells
    Patent number: 5718955
    Abstract: A composite material for controlling oxygen flux into a thermal cell comprises a bottom sheet formed to have a pocket. The bottom sheet is impermeable to oxygen. A plurality of particles is placed in the pocket. The plurality of particles reacts exothermally when exposed to oxygen. A top sheet is sealed to the bottom sheet at a flange around the pocket to enclose the plurality of particles such that the particles cannot fall out of the pocket. The top sheet has a substrate which is highly permeable to oxygen. The substrate is coated with an oxygen permeable silicone based elastomer to a thickness which regulates an oxygen flux into the pocket when the top sheet is exposed to oxygen. The composite material further comprises an oxygen impermeable barrier film bonded to the top sheet by pressure sensitive adhesive for preventing exposure of the top sheet to oxygen until the body warmer is intended to be used.

  • Electroluminescent device and method for producing the same
    Patent number: 5714274
    Abstract: An electroluminescent device has a luminescent layer including an alkaline earth thiogallate doped with a luminescent center for producing blue light. An insulating layer disposed next to the luminescent layer includes a buffer area contacting the luminescent layer. The buffer area is made from a material which has an amorphous state at a temperature sufficient for crystallization of the alkaline earth thiogallate. Thus, when the device is manufactured, the luminescent layer can be formed in an amorphous state on the insulating layer and heat treated. Since the buffer layer remains in an amorphous state, the formation of alkaline earth sulfides which might degrade the color purity of emitted light at the interface of the crystalline luminescent layer and the amorphous buffer layer can be prevented.
