TH31493A - A method for manufacturing ink-based packaging materials, especially for sterile packaging. - Google Patents

Abstract

DC60 (30/01/47) This disclosure is about a method for producing decorative packaged pellets. With a type of sterile packaging inks that are manufactured with that fiber The packaged pellets are then subjected to hydrogen peroxide treatment. Before the fiber reshaping into sterile packaging for the purpose of sterilization, the packaged stacking sheets are manufactured so that the fiber membranes with a polyethylene outer coating. The low density (LDPE) coating is then corona treated with a modified polar state for the purpose of promoting adhesion, after which the treated outer LDPE coating is then classified. To have Decorative parts that are water-based inks Which is then fed over the desired pattern on the outside of the glaze. By applying the fibers decorated with such inks through subsequent treatment for Reduces facial skin energy A packaged stacking sheet is obtained which is susceptible to sterilization. Using a much reduced hydrogen peroxide At the same time that the good adhesion between the water-based inks and outer LDPE coating is guaranteed. This disclosure is about a way to manufacture sterile packaging ink-lined packaging overlays for those manufactured with which the membrane of the packaged overlay is passed. Hydrogen peroxide treatment before fiber contouring into sterile packaging for sterile purposes. The packing overlays are produced so that the pulp of the paper is Which has an outer coating of low density polyethylene (LDPE) is passed through Corona therapy that modifies its polar state for the purpose of promoting sticking. After that, the treated outer LDPE coating is then provided with a water-based ink-based finishing element. Which is then fed over the desired pattern on the outside of the glaze. The fibers that are decorated with such inks are treated after post treatment to reduce surface energy A packaged piling board was obtained with a significantly reduced hydrogen peroxide sterilization sensitivity. At the same time that the adhesion between Water-based inks and outer LDPE coating are guaranteed.

Claims (7)

1. The manufacturing method of ink-decorated packaging materials consists of (a) the creation of a stacked sheet with a paper core layer with a heat-sealable outer plastic layer on the opposite side. (B) Applying a corona-discharged surface treatment with at least one outer plastic layer (c) Applying water-based inks with the outer layer of corona-ionized inks. That is at least one layer of plastic on the outside This is a layer where the treatment is applied to the surface where corona (d) is released, reducing the surface energy of the layer. The outer layer of plastic is at least one layer where the corona-discharged surface treatment is applied, and (e) is followed by a hydrogen peroxide facial treatment with a At least one layer of plastic outside. Where the reduction of facial energy includes heating the surface Of at least one outer plastic layer And where reducing the surface energy after printing will make the decorated packaging material absorb less hydrogen peroxide. During sterilization of plastic coated fibers 2. Claim Method 1 where at least one outer plastic layer is formed from low-density polyethylene. 3. The method of claiming in claim 1 where the reduction of surface energy includes moving the stacked sheet through the clamping gap between the hot rollers. 4. Method as claimed in claim 1, where the stacked sheets are formed as a package after the application of the hydrogen peroxide surface treatment. By thermally sealing at least one outer plastic layer portion. 5.Packaging materials manufacturing method The thermally sealed liquid food container consists of: (a) the conductivity of the plastic-coated paper pulp through the clamping cavity by a pair of rollers; (b) the conductive membrane as a barrier material. Gas travels through the first pair of rollers (c). Inserting glue into the clamping slots of the first pair of rollers. Between the paper coated with plastic (D) The use of a heat-sealable plastic layer over the gas barrier material (e) the use of a corona-discharged surface treatment with the plastic surface of the coated paper. (F) the use of water-based inks to the plastic-coated paper surfaces of the plastic-coated paper (g) the reduction of surface energy of the plastic-coated paper surfaces, and (h) followed by the use of Facial treatment With hydrogen peroxide to paper coated with plastic Where treatment of corona-charged surfaces increases the adhesion of the ink coating. And by reducing the surface energy after printing, the decorated packaging material absorbs less hydrogen peroxide during sterilization of the plastic coated fibers. Where the reduction of facial skin energy This includes moving the plastic coated paper between the heat press roller. 6. Method as requested in claim 5, where the heat-sealable plastic layer is formed from low-density polyethylene. 7. Method according to the claim in claim 5, where the gas barrier material is aluminum foil
