Definitions

  • This invention relates to printed flexible packaging materials, especially lay-flat packaging articles such as end-seal bags and side-seal bags, as well as casings.
  • the present invention provides a process for producing a flexible, lay-flat packaging article having printing on both sides thereof, without having to perform distinct printing operations on each side of a lay-flat tubing from which the article is formed.
  • the present invention can also be used to provide a flexible, lay-flat packaging article having printing on the side-edge regions of the article, without having to print close to one or more of the side- edges of the lay-flat tubing.
  • the present invention is directed to a printed lay-flat article comprising a printed flexible film wherein the print is on both lay-flat sides of the article. However, the print is confined to a printed region extending around a first half of the printed article. The second half of the printed article has no printing thereon.
  • the article e.g., bag
  • the article can have a patch adhered thereto.

Abstract

L'invention concerne un article pouvant être mis à plat constitué d'un film souple et comportant une impression sur ses deux côtés de mise à plat, cette impression étant confinée dans une zone d'impression située autour d'une première moitié de l'article imprimé, la seconde moitié dudit article ne comportant aucune impression. Un procédé de fabrication de cet article plat permet de réaliser l'impression uniquement sur un premier côté de mise à plat d'un tube souple, lequel est alors reconfiguré selon une seconde configuration de mise à plat de façon que l'impression soit réalisée sur les deux côtés de mise à plat de ce tube dans la seconde configuration de mise à plat. Ledit tube est alors converti (par coupage et éventuellement par soudure) en article d'emballage, de préférence en sac, et notamment en sac à soudure terminale ou à soudure latérale. Dans un autre mode de réalisation, un article d'emballage imprimé sans adhésif constitué d'un film souple comporte deux zones imprimées, l'une de ces zones recouvrant un premier bord latéral de l'article, l'autre recouvrant le second bord latéral dudit article. Le procédé de fabrication de cet article consiste à réaliser une impression sur les deux côtés de mise à plat initiaux d'un tube, puis à opérer une reconfiguration de façon à obtenir une seconde configuration de mise à plat dans laquelle les zones imprimées sont situées sur les bords latéraux du tube reconfiguré. L'invention concerne également des produits emballés au moyen de ces articles.
