The balloon structure of inkjet printing comprises: a vinyl resin layer (EVOH/ethylene and vinyl alcohol copolymer resin); a linear polyethylene layer (LLDPE) combined with the vinyl resin layer to form a base material; an ink-absorbing layer coated onto a side surface of the base material facilitating the absorption of ink from an inkjet printing device to form into patterns/characters; and a soft pad layer being a thin body having a side surface coated with a glue layer which can be easily removed for adhesion onto the other side surface of the base material to increase the thickness of the base material which can be delivered by the inkjet printing device. The inkjet printing device prints words, patterns onto the ink-absorbing layer. The soft pad layer is then removed, and by means of the hot sealing, and cutting steps, specific character, patterns, drawings are printed onto the balloon.

  • Patent number: 6596289
    Abstract: A garment for treating the skin, a method of making the garment and a method of using the garment to treat the skin, made of garment material, in particular hose material to be worn tightly against the skin, which has a multiplicity of durable chemical bonding sites. The durable sites which are preferably of the type to make covalent bonds, are bound to binding molecules which form chemical hooks for the garment material. Each of the chemical hooks has one or more semi-durable chemical bonding sites of the type which can chemically bond an active ingredient molecule to the binding agent but which is broken in the presence of skin conditions which are normal such as normal skin pH, normal skin moisture and normal skin heat generated both by body heat and the heat of friction of the garment rubbing against the skin. Active ingredient molecules such as molecules of theophylline or theophylline complexes are bound to the binding agent and are released to the skin when the garment is worn.

  • Publication number: 20030113565
    Abstract: Weatherproof sheets, suitable for conventional printing, writing, photocopying, and laser printing, are prepared by impregnantly coating a cellulosic substrate on at least one side with a durable weatherproofing composition that is water-based. The composition that is used for general-purpose weatherproof sheets comprises a styrenic acrylic copolymer, a wax, a filler for blocking resistance, a filler for tooth, and a pigment. The preparation of all-purpose weatherproof sheets, usable in photocopiers and laser printers, is made possible by substantially omitting calcium carbonate and titanium dioxide from the composition. The weatherproof sheets resist falling apart, remain legible, and can be written upon when wet. They are also non yellowing, biodegradable and recylclable. Also, disclosed are methods for making the weatherproof sheets, as well as weatherproof sheets made by those methods.

  • Patent number: 6552536
    Abstract: A reference standard and method for inspecting dual-layered coatings. The reference standard has a first layer adherent to a substrate, the first layer has a predetermined thickness that increases in one direction. Adherent to the first layer is a second layer, the second layer has a predetermined thickness that increases in a direction orthogonal with the first layer. The orientation of the first and second layers of the reference standard provides a spectrum of the possible variations of the dual-layered coating.

  • Patent number: 6170426
    Abstract: Apparatus and methods for producing dry, wet or partially wet and partially dry segments of tissues. The tissue dispenser generally comprises a housing having a tissue egress passage, a tissue source of a predetermined quantity of dry tissue located in the housing, a fluid source of a predetermined volume of fluid located in the housing, and an actuatable application mechanism in fluid communication with the fluid source and operationally positioned proximate to the tissue egress passage. The application mechanism can be actuated to dispense fluid onto the tissue as the tissue passes through the tissue egress passage. A partially wet and partially dry tissue can be used to clean and dry an article. The tissue may generally comprise a cleansing pad having an impermeable membrane positioned between two tissue segments to form a wet tissue area and a dry tissue area. The impermeable membrane prevents fluid from bleeding into the dry tissue area. The tissue may also comprise a pad attached to a bubble of fluid.

  • Patent number: 6153040
    Abstract: A process for reducing rollups in gypsum board panels when the panels are laminated with a laminate, is provided. A laminator is provided, as is at least one gypsum board panel, each panel having a face paper layer and a backing paper layer. Each paper layer has a coefficient of friction, and at least one of the face paper layer and the backing paper layer is treated with an agent for reducing the coefficient of friction and water absorbency. Next, a supply of laminate is provided and installed in the laminator. Then, at least one panel of the gypsum board is fed through the laminator, so that a layer of the laminate is applied thereon.

  • Patent number: 6143863
    Abstract: A lactide polymer composition combining compositional and purity limitations and catalyst optimization or addition of stabilizing agents resulting in a melt-stable polymer is disclosed. The melt-stable lactide polymer comprises a plurality of polylactide polymer chains, residual lactide in concentration of less than 2 percent and water in concentration of less than 1000 parts-per-million. A stabilizing agent in an amount sufficient to reduce depolymerization of the lactide polymer during melt-processing or alternatively, control of catalyst level at a molar ratio of monomer to catalyst greater than 3000:1 is also included in the melt-stable composition. A process for manufacture of a melt-stable lactide polymer composition includes polymerizing a lactide mixture and adding stabilizing agents sufficient to reduce depolymerization of the polylactide during melt-processing, followed by devolatilizing the polylactide to remove monomer and water.

  • Patent number: 6133166
    Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes, which are dry until used, where fluid is released from the article. These articles comprise:a. a carrier comprising a cellulosic fibrous structure having at least a first region of relatively high basis weight that comprises an essentially continuous network and a second region of a plurality of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; andb. an emulsion applied to the carrier, where the emulsion provides fluid for cleaning when shear forces are applied to the article.The first and second regions of the cellulosic fibrous structure are disposed in a nonrandom, repeating pattern. The articles offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like).

  • Patent number: 6007666
    Abstract: According to the present invention, a laminar wrapping paper is provided comprising first and second paper layers or laminae. Each lamina has an inside surface coated with a barrier coating. The layers are laminated by heat lamination, wherein the barrier coatings are melted together, or by providing an adhesive between the coated inside surfaces. The lamination may be accomplished in a selective or discontinuous manner in order to form air pockets within the laminar structure to increase the insulation characteristics of the wrapping paper. A plasticizer is applied to the outside surface of the first lamina. Graphic designs or lettering may be printed on the outside surface to identify the wrapped product or for purposes of decoration. The present invention is also directed at a process and apparatus for manufacturing the laminar wrapping paper described herein. First and second webs of paper are unrolled and passed through coating apparatus to coat one side of each web with a barrier coating.
