  • the aluminium sheet of a thickness of 7 up to 10 microns provides for a barrier against penetration of fats or other oily or greasy matters into the package structure and for an external protection against such materials
  • Such a packing material offers sufficient protection against penetration of moisture, oily stuffs air and even light inside the package and good mechanical properties allowing for the material consistency and for closing the packages by covers and other means Last but lost such packing materials allow also for high quality prints on the package surface
  • the technology of manufacture of the materials have been widely developed and the materials are applied without problems
  • aluminium has a negative influence upon human life and therefore its consumption in the food industry decreases and in some countries has been forbidden
  • This negative feature is accompanied by a difficult and often insufficient handling of wastes comprising aluminium
  • Production wastes of this kind by producers of said packing materials amount up to 30 % of raw materials Handling of such production wastes or wastes comprising packages of consumed food is very costly but from the point of view of ecology is more and more demanded
  • aluminium belong to so called strategy raw materials the price of which is relatively high and has increasing tendency Therefore producers of said packages try to decrease content of aluminium in a total package mass

  • the packing material according the invention is environment friendly and allows for a biological degradation
  • the used package made of the said material is capable of recycling and therefore helps to cut costs by the producer as well as by the user producing packed food as they have to carry the costs for removal of used packages

Abstract

L'invention concerne une matière d'emballage destinée à un dispositif d'emballage utilisé dans l'industrie alimentaire, de préférence pour la fabrication de cornets de crème glacée et de paquets formés utilisés dans de nombreuses applications. Cette matière d'emballage comprend au moins une couche de papier de base à base de cellulose de pâte de sulfate blanchie, cette couche de papier de base étant pourvue d'une couche intérieure renfermant une dispersion anionique d'une cire et de paraffine avec un copolymère, et d'une couche extérieure renfermant au moins un revêtement avec un mélange de kaolin et de calcaire. La couche de papier de base comprend entre 60 et 80 % en masse d'une cellulose coniférienne de pâte de sulfate blanchie et entre 20 et 40 % en masse d'une cellulose de feuillu de pâte de sulfate blanchie, avec des composants contenant entre 5 et 25 % en masse de calcaire, entre 0,5 et 2,0 % en masse de fécule de pomme de terre cationique, et entre 0,5 et 2,0 % en masse d'un agent de collage à base de résine polyamide, la masse chargée des composants correspondant à la masse de cellulose totale.
