With Or Including Surface Preparation For Coating Patents (Class 493/326)
  • Publication number: 20140069923
    Abstract: A method for preparing a scored flexible structure that has utility in the construction of packaging structures, including steps of: (i) providing a structure as a web of flexible material; (ii) enhancing a thickness of the structure in a discrete region thereof by applying a substantially all-solids electron-beam-curable polymer material in fluid form onto the discrete region, the discrete region occupying a minor percentage of a total surface area of the structure; (iii) curing the polymer material by irradiating the polymer material with an electron beam, thereby forming an EB-cured polymer region; and (iv) forming a score line through a thickness of the EB-cured polymer region and through the thickness of the structure.

  • Patent number: 7074476
    Abstract: A flexible carrier for carrying a plurality of beverage containers includes a plurality of container holders, each having a portion with higher energy treatment and a portion with lower energy treatment. The energy treatment is corona or plasma treatment. The portions with higher energy treatment provide better carrier-to-container friction. By varying the level of energy treatment and the relative size of the portions being treated, the amount of overall friction between the flexible carrier and the containers can be controlled.

  • Patent number: 5776619
    Abstract: An improved coated paperboard or plate stock useful for forming substantially rigid food containers such as plates, bowls, trays and the like and a process from producing the improved coated paperboard are provided. A base coat comprising a styrene acrylic latex and a pigment is applied directly to the paperboard, and a top coat comprising a styrene acrylic polymer latex and a pigment is applied directly to the base coat to form the coated plate stock. The improved coated plate stock is characterized by improved grease, oil and cut resistance, improved varnish gloss, enhanced smoothness, and improved printing quality.

  • Patent number: 5143281
    Abstract: The invention relates to a folding box of composite cardboard material coated heat sealably at least on the inside, which has a flat bottom to which two pairs of opposite triangular folding pockets are sealed lying flat. To prevent bubble formation on the inside of the package, more particularly those areas of the triangular folding pockets which are to be sealed to one another over their complete surface, due to steam forming in the composite cardboard material during the heat activation of the areas, the heat sealable coating is perforated right into the cardboard in the areas.

  • Patent number: 5088643
    Abstract: The polymer coated exterior of a paperboard container used to package liquid products is selectively treated with a flame or corona to raise the surface tension in the areas which are intended to accept ink while eliminating or canceling any surface treatment in the region where a pour spout fitment is to be bonded to the container.

  • Patent number: 4710358
    Abstract: To change the surface tension of cup-like containers by means of corona treatment, the containers are placed on a mandrel and are moved by drive wheels in such a way that the cup-like container is caused to roll off on the mandrel with the inside of the wall. Via an electrode the discharge current is supplied across the discharge gap to the cup-like container and it is removed via the mandrel, which is connected as counter-electrode. To avoid a discharge gap on the inside of the wall, the mandrel has connected to it a guide shoe which always applies against the inside of the wall.

  • Patent number: 4425108
    Abstract: A polyethylene shipping bag having an internal nylon barrier coating which permits packaging of materials which normally migrate through polyethylene. The coating is flexographically applied from a nylon solution in a lower aliphatic alcohol with up to 15% water to a polyethylene film which has been previously treated to make it receptive to printing ink. The bag may be single ply or double ply and may have a filling valve.
