Definitions

  • This invention relates generally to a process for use in the production of food and beverage packagings and, more particularly, to a process for applying various beneficial coatings in a predetermined manner onto food and beverage container surfaces.
  • Polyethylenes e.g. - LDPE (low density polyethylene) are commonly used in paperboard packaging as the innermost package layer because they are liquid tight and provide an effective matrix by which package seals are accomplished. Polyethylenes can scalp certain food and beverage flavors. Such scalping can in turn result in a modification of product flavor and shorten the shelf life of the product. Polyethylenes and other known product contact layers can also impart an undesirable flavor to the product contents.
  • LDPE low density polyethylene
  • the present invention provides a method of selectively coating a surface area of a food and/or beverage container with a material to achieve a desired effect.
  • the coating material may be printed onto a surface (ordinarily, but not necessarily, the product contact or inner surface) of the packaging in a predetermined area and geometry to achieve the desired benefits without having the coating interfere with the sealing or other mechanics of the container. Further a coating may only be needed in a particular "zone" of the packaging surface such that different coatings may be applied to the same packaging in different zones (i.e.-on different areas of the same surface).
  • the present invention is useful for coating surfaces of packagings comprising a paperboard substrate.
  • packagings containing other substrate material are within the scope of this invention.
  • food and beverage packagings are extrusions of multiple material layers or laminations of various plastics onto a paperboard substrate to make the paperboard suitable for food and beverage containment.
  • the packaging may typically be a multi-layered structure having a material such as LDPE, for example, as the innermost or product contact layer.
  • LDPE low density polyethylene
  • the well known gable top milk cartons, aseptic beverage packages, and frozen food packagings are examples of these multi-layered structures.
  • FIG 1 is an example of an unfolded, pre-formed paperboard container which incorporates the present invention.
  • Packages which contain products that include essential oils, for example, are well known in the art.
  • a typical multi-layered container cross-section is illustrated in Figure 2 and is used herein for example purposes and is not to be construed to limit the invention to this structure.
  • the structure 10 includes a substrate 12 such as paperboard, an outer LDPE layer 14 applied to the outer surface of the substrate 12, an inner oxygen barrier layer 16 and an inner LDPE product contact layer 18 interior to the oxygen barrier layer 16.
  • a coating 20 may be applied to the inner product contact layer 18.
  • Certain resinous materials are known to be resistant to scalping for example and could be used as the coating 20.
  • the product contact layer 18 has a sealing surface 22 and a non-sealing, product contact surface 24.
  • the application of a particular coating 20 to the sealing surface 22 of the product contact layer 18 could adversely affect the sealability performance of the container. Accordingly, with the method of the present invention, the coating 20 may be applied to the non-sealing surface 24 of the product contact layer 18.
  • the coating may be applied by well known printing processes such as rotogravure, offset or flexographic.
  • the coating could also be applied to the product contact layer 18 by methods such as spraying, rolling or brushing while taking commonly known measures to maintain control of the precise area to be coated.
  • the method of the present invention may also be used to selectively coat the sealing surface 22 with a material that enhances sealing formation while preferably keeping this coating out of the non-sealing zone 24.
  • Other zones of a package may also be selectively coated for other reasons. This demonstrates the versatility of the present invention.
  • Coatings for use with the present invention may be any of a number of materials known to have desirable characteristics, for example, enhanced sealing as described above, and improved resistance to bending and folding induced stress cracking. Other benefits may include resistance to scalping or flavor migration, and oxygen scavenging (since oxygen has negative effects on product quality and shelf life and it would be desirable to have such oxygen adsorbed into the packaging, thus precluding its reacting with the contents).
  • the coating may include, but is not limited to, polyesters, latex, PVDC's or other carrier resins capable of forming a suspension or emulsion which may be based in water or volatile solvent systems such as toluenes, acetates, alcohols and the like.
  • the coating may be applied to the inner surface of the packaging material, in register, and cured in the same manner as printed graphics are to the outside surfaces of a package.
  • the use of such solvent systems would facilitate the printing lay down technique since the behavior of these emulsions is similar to that of printing inks.
  • Another advantage of the present invention is that different types of coatings may be concurrently applied to different zones of a packaging surface to accomplish different objectives. This is done in much the same way as different colored inks are applied onto a package for obtaining a multi-colored packaging face. Examples of such embodiments of the present invention are shown in Figures 3 and 4.
  • coating C1 30 and C2 40 may be applied to different zones of the package to accomplish separate objectives.
  • the coating C1 30 may comprise a material composition that absorbs oxygen while coating C2 40 may offer improved resistance to stress cracking.
  • the coatings 30 and 40 may be applied using the same process as used to apply the coating 20 as described above.
  • the positioning of the pattern for applying the coatings is controlled by the print registration control system known to those of ordinary skill in the art.
  • the coatings may be applied using standard printing cylinders engraved with a predetermined pattern to lay the coating onto a continuously moving packaging material web.
  • the positioning of the coating on the web is precisely controlled by print registration.
  • coating C2 40 is shown being applied onto a portion of coating C1 30.
  • This embodiment is offered to demonstrate that the coatings may be applied in a juxtaposed relation or a stacked relation. In a stacked relation two or more coatings may interact in a particular beneficial way to provide a unique package characteristic(s).
