Problems solved by technology

[0009] However, a limitation, and one that would limit shelf life, would occur very occasionally and increase mold spores on the packaging laminate
These spores can contaminate, for example, packaging materials stored in certain environments, and they have proven to be more difficult to eliminate than most other microorganisms

Embodiment Construction

[0038] With reference to the accompanying drawings, figure 1 It is shown how a web 1 of packaging material is processed and progressively advanced between different processing operations and processing stations to be continuously transformed into a filled and sealed packaging container which can bring significant benefits to the product. Improved shelf life and, at least in some cases, also suitable for non-refrigerated distribution.

[0039] The wrapping material is made with a core layer of paper in the center, and layers of thin, liquid-impermeable plastic material (eg thermoplastic, such as polyethylene) for both sides. The packaging material may also include additional layers, such as layers of air impermeable material, such as aluminum foil or some type of barrier plastic, such as a copolymer of ethylene vinyl alcohol copolymer (EVOH).

[0040] The packaging material 1 in the form of a web is initially wound on a magazine reel, which is arranged at the first end of the ...

Abstract

The invention relates to a method of producing a packaging container with low microbiological load by treating the packaging material with a combination of a chemical sterilization agent and UV-light. The invention is characterised in that a first partial quantity of the chemical sterilization agent is applied on the packaging material a sufficiently long time before the packaging material is irradiated with UV-light in order for a predetermined portion of expected microorganisms to have time to absorb a sufficient amount of the chemical sterilization agent in order to be exterminated on being irradiated with UV-light, and that a second partial quantity of the chemical sterilization agent is applied on the packaging material in a sterile chamber before the packaging material is irradiated with UV-light. The invention also relates to a device for realizing the method, and a filling machine provided with the device.

Description

technical field [0001] The present invention relates to a method of producing packaging containers with a very low microbial load by treating the packaging material in a filling machine with a combination of chemical sterilants and ultraviolet light. The invention also relates to a device for producing packaging containers with a very low microbial load in a filling machine, said device being suitable for treating the packaging material with a combination of chemical sterilants and ultraviolet light. Furthermore, the invention relates to a filling machine having said device. Background technique [0002] Packaging containers for consumer products of various types, such as milk or juice, may be of the type made from a packaging laminate comprising a core of paper or paperboard and one or Multiple barrier layers such as thermoplastic and aluminum foil. [0003] A common type of packaging is manufactured in a packaging and filling machine where the packaging laminate web is d...
