Definitions

  • the present invention relates to a method for producing composite films by means of a solvent-free adhesive system, in particular composite films with barrier properties, and to composite films obtainable by this method.
  • packaging materials with a wide variety of property profiles are required in the packaging industry.
  • the packaging material used may be permeable to gases such as, for example, oxygen, nitrogen, carbon dioxide and moisture, or to have a reduced permeability or impermeability.
  • Packaging materials with barrier properties should in particular be able to preserve the atmosphere contained or intended in the packaging, for example a nitrogen protective gas atmosphere, in order to be able to guarantee the quality of the packaging goods even over a longer period of time.
  • Such materials are also intended to prevent the penetration of oxygen and / or moisture into the packaging, which could spoil the goods.
  • packaging materials used should be as inexpensive as possible. This requires corresponding economic manufacturing processes.
  • BESTATIGUNGSKOPIE In order to increase the barrier properties of films, two or more films are glued together to form a composite film, an adhesive with barrier properties being used as the adhesive. Thus, according to the invention, double, triple, quadruple composite films and composite films with more than 4 films can be obtained.
  • Adhesive systems which are preferably used are solvent-free, since the energy-intensive removal of solvents, which requires additional work steps and is therefore expensive, is eliminated, as is the case in conventional solvent-based adhesive systems.
  • a solvent-free adhesive system based on polyurethane for the production of composite films with barrier properties, which comprises a polyester resin with hydroxyl groups as the first adhesive component and a diisocyanate as the second hardener component.
  • the polyester resin having hydroxyl groups is obtained by reacting a linear aliphatic diol having two to ten carbon atoms with a linear dicarboxylic acid, n-butanediol and N-hexanediol being the preferred diols and adipic acid being the preferred dicarboxylic acid.
  • the polyester resin used is in crystalline form at room temperature and has a melting point of about 80 ° or less, with lower melting polyester resins being preferred.

  • the hydroxyl number of the polyester resin component is stated to be about 20 to about 350, preferably about 100 to about 250. Due to the low melting point of the polyester resin, the adhesive system can also be used at the low temperatures that are required to prevent deformation or other impairment of the polymer films due to the high temperature.
  • Aliphatic, preferably linear, but also aromatic diisocyanates are mentioned as the diisocyanate component.
  • the two components of the adhesive system are heated to the lamination temperature and applied to the first film immediately before the second film is laminated on. To fully harden the composite film obtained, it is recommended to store it for at least one week afterwards.
  • the films described in the working examples show good barrier properties with regard to oxygen permeability and, in one case, for moisture permeability.
  • aromatic diisocyanates as adhesive components or to replace them with aliphatic ones.
  • US 4,496,417 describes a laminating device for connecting a plastic film to a reinforcing material made of paper.

  • the method according to the invention enables the post-curing time of the finished composite films to be shortened.
  • the object of the invention is achieved by a method for producing composite films by gluing a first film to a second film by means of a solvent-free adhesive system, the adhesive system being preheated to the application temperature in a first stage, in a second stage, the adhesive system preheated to the application temperature, if appropriate after mixing individual adhesive system components, is applied to the first film, and in a third step the first film coated with the adhesive system is connected to an incoming second film with cooling.
  • adhesive systems based on aliphatic, in particular aliphatic linear, diisocyanates can be used to obtain composite films with excellent barrier properties economically and without problems.
  • this process can shorten the curing time of the films to a few days.
  • Temperature logistics has proven to be a decisive factor for the method according to the invention, in particular adequate preheating of the adhesive system or its components, ensuring the application of the adhesive system to the first film at the application temperature required for the materials used, and cooling of the first film during the lamination of the second film.
  • the total amount of the adhesive system that is applied to the first film should have a temperature that is as constant and uniform as possible.
  • the individual adhesive components are therefore preheated over a period of time which is sufficient to ensure that the temperature of the components used is as uniform as possible.
  • the accuracy and uniformity of the application temperature achieved by the above measures guarantees the accuracy of the viscosity of the adhesive system and thus a uniform quality of the adhesive application.
  • the risk of nonsense is avoided, that is to say the spraying of adhesive system applied to the film.
  • the second film is bonded to the first film provided with the adhesive system while cooling the first film.

  • the amount of adhesive system applied depends on the type of film to be laminated and the type of adhesive system itself.
  • the application amount is usually between 1.5 to 4 g / m 2 , preferably 2.0 to 3.0 g / m 2 and in particular 2.5 to 2.7 g / m 2 .
  • the web tension should be regulated so that a uniform tension is exerted both on the two individual films and on the laminated film composite. This measure increases the overall product quality. This also promotes the quality of the adhesive and the winding of the film.
  • any solvent-free adhesive system can be used for the method according to the invention.
  • These adhesive systems contain as an adhesive component a polyester resin with hydroxyl end groups, which is the reaction product of a linear aliphatic diol with 2 to 10 carbon atoms and a linear dicarboxylic acid.
  • the polyester resin is crystalline at room temperature and has a melting point of about 80 ° C or less, with lower melting polyester resins being preferred.
  • the number average molecular weight (M n ) is from about 300 to about 5,000 and the OH number is from about 20 to 350, with from about 100 to about 250 being preferred.

  • aliphatic and aromatic diisocyanates can be used for the hardener component.
