Definitions

  • the labels may consist of organic polymers such as cellophane.
  • Cellulose is widely used in nature. It is a biopolymer of ß-1, 4-linked cellobiose units. Usually, the cellulose forms unbranched water-insoluble chains. The molar weight can be between 50,000 and 500,000 g / mol (determinable by GPC method).
  • GPC method GPC method
  • a viscose solution is prepared from cellulose, which can be processed into films. By appropriate selection Of the materials used, it is possible to use cellulose films also for food packaging.
  • the amount of the base polymer should preferably be between 5 to 50 wt .-%, based on the total hot melt adhesive. It can be a base polymer, but several can be used in a mixture. It is preferred if portions of these base polymers contain polar groups, for example OH, NH, polyether, COOH, SO 3 H or urethane groups. These can be copolymerized directly in the synthesis by selecting the monomers, but it is also possible to reactivate them by subsequent modification of the polymer backbone. According to the invention it is expedient that between 0 to 40%, in particular up to 30%, based on the base polymers, of a base polymer which has polar groups is contained in the pressure-sensitive hotmelt adhesive.
  • esters as plasticizers, for example liquid polyesters and glycerol esters such as glycerol diacetate and glycerin acetate, and also neopentylglycol dibenzoate, glyceryl tribenzoate, pentaerythritol tetrabenzoate and 1,4-cyclohexanedimethanol dibenzoate.
  • alkyl monoamines and fatty acids having preferably 8 to 36 carbon atoms.
  • White oil and naphthenic mineral oil are also suitable.
  • the pressure-sensitive hot-melt adhesives according to the invention can be applied by known processes.
  • the material of the labels, a film, a multilayer film or paper can be processed by the web.
  • these webs may be subjected to a pretreatment on the surface. It is known to print, emboss, laminate into multilayer films, or use other processes to produce a high quality surface and optical appearance.
  • an adhesive hot-melt adhesive according to the invention is then applied.
  • the application can be done over the entire webs, that is, the entire surface is coated evenly.
  • Another mode of operation applies the hotmelt adhesive only to individual parts of the webs. This can be done, for example, strip-shaped or other patterns are applied to the web surface. This can be done for example by doctor blades, slot dies, printing units, spray application, roller application or curtain or roller coating.
  • the web can be made into suitable labels.
  • the perforation may be performed at different times.
  • the sheet material is perforated before or after printing.
  • the adhesive labels are perforated.
  • the perforation can be selected from an aesthetic point of view, it is essentially essential to the invention that there is sufficient perforation on the surface coated with the pressure sensitive hotmelt adhesive.
  • a preferred method of operation according to the invention covers the side of the label already coated with the pressure-sensitive hotmelt adhesive with a protective film and brings it into a form such that storage is possible. This can be done for example by stacked storage or rolling the labels on a substrate, in particular on the protective film. Immediately prior to use for bonding, the labels are then removed from the substrate and adhered to the substrate.
  • the process according to the invention finds particular application in the packaging industry, that is to say in the labeling of cardboard boxes, hollow bodies and film packaging.
  • suitable film material of the labels in conjunction with the pressure-sensitive adhesives suitable according to the invention it is possible to achieve non-slip, stable adhesions of labels on the substrates, in particular hard, water-repellent substrates, even in the presence of moisture. However, these are easy to remove under the known conditions in alkaline aqueous solution. In this case substrate surfaces are obtained with only small adhesive residues.
  • Comparative Example Bonding The same hotmelt adhesive is applied to a cellophane label of the same strength with a Cobb value of 0.25 g / m 2 per 20 sec. The label is glued and tested for peeling in the alkaline medium. The adhesive / label is for the most part not replaced after 4 minutes of the wash-off test.

Abstract

L'invention concerne un procédé de collage d'étiquettes sur des substrats hydrophobes, selon lequel un adhésif thermofusible est déposé sur l'ensemble ou sur une partie de l'étiquette ou du substrat, sur une surface faisant face à l'étiquette, puis l'étiquette et le substrat sont assemblés et collés. L'invention est caractérisée en ce que l'adhésif thermofusible est soluble dans une solution alcaline et en ce que l'étiquette est choisie parmi i) des étiquettes perméables à l'eau avec une absorption d'eau (valeur de Cobb) supérieure à 0,3 g/m2 par 20 sec, ii) des étiquettes perforées, présentant une perforation ou des ouvertures inférieures à 10 % sur la surface collée. L'invention concerne également une étiquette enduite d'un adhésif thermofusible hydrosoluble, ladite étiquette présentant une absorption d'eau élevée et/ou comportant éventuellement des perforations ou des ouvertures sur la surface collée.
