FolieFoil
Foreliggende oppfinnelse vedreirer en folie eller film for innpakking, hvis permeabilitet overfor gass kan innstilles av-hengig av det spesielle bruksformål. The present invention relates to a foil or film for packaging, whose permeability to gas can be adjusted depending on the particular purpose of use.
Under lagring og behandling (modning) av noen næringsmidler, såsom ost, er det meget viktig å beskytte produktet mot oksygen During the storage and processing (ripening) of some foodstuffs, such as cheese, it is very important to protect the product from oxygen
■for å hindre utviklingen av mikroorganismer og dannelse av mugg eller sopp på produktets overflate. Innpakningsmaterial et for ost må slippe gjennom en viss mengde karbondioksyd for å hindre den tettomsluttende emballasje i å bule seg ut og revne. Karbondioksyd utvikles både av aerobe og anerobe mikroorganismer. Innpakningsmateria let må ha lav permeabilitet overfor vanndam<p>for å hindre osten i å tørke. Alle ostetyper med forholdsvis • lang behandlingstid på for eksempel en til to måneder,krever dunder ideelle betingelser et innpakningsmateriale hvis nermea-bilitetstall for karbondioksyd og oksygen ligger innenfor visse ■to prevent the development of microorganisms and the formation of mold or fungus on the product's surface. Packaging material for cheese must let through a certain amount of carbon dioxide to prevent the tightly enclosing packaging from bulging and tearing. Carbon dioxide is produced by both aerobic and anaerobic microorganisms. The packaging material must have a low permeability to water to prevent the cheese from drying out. All types of cheese with a relatively • long processing time of, for example, one to two months, under ideal conditions require a packaging material whose permeability values for carbon dioxide and oxygen lie within certain
-grenser.-limits.
Et stort antall forskjellige materialer benyttes for tiden '■ som innpakningsmateriale ved behandling og lagring av ost, for eksempel nitrocel lulose ,- lakkert cellofan laminert i nolyeten,. polyester laminert i nolyeten, polyamid laminert i nolyeten, A large number of different materials are currently used as wrapping material when processing and storing cheese, for example nitrocellulose, lacquered cellophane laminated in polyethylene. polyester laminated in nolyethene, polyamide laminated in nolyethene,
polyvinylklorid-lakkejt cellpfan laminert i polyeten og Polyvinyl chloride-lacquered cell pfan laminated in polyethylene and
polyvinylklorid-folie. Alle disse innpakningsmaterialer har polyvinyl chloride foil. All these wrapping materials have
visse verdier for permeabilitetene av karbondi oksyd, vanndamn certain values for the permeabilities of carbon dioxide, water dam
og oksygen under bestemte lagringsbetingelser ( temperatur og fuktighet), men i praksis er imidlertid ikke disse egenskaper tilstrekkelig til å oppfylle kravene som er nevnt ovenfor. and oxygen under specific storage conditions (temperature and humidity), but in practice these properties are not sufficient to meet the requirements mentioned above.
Filmene som benyttes er enten for tette eller for gjennomtrengbare. I tysk offentliggjøringsskrift 2.318.028 er det beskrevet ;et innpakkingsmateriale hvor en gasstett folie og en gass-;gjennomtrengbar folie er kombinert. Dette pakningsmateriale er'beregnet for innpakking, av ferskt kjøtt og er forsynt med et.. The films used are either too dense or too permeable. German publication 2,318,028 describes a packaging material in which a gas-tight foil and a gas-permeable foil are combined. This packing material is intended for wrapping fresh meat and is provided with a..
tosjikts dekklag, et sjikt som er gasstett og kan rives bort for å blottlegge det andre sjikt som ér gjennomtrengbart for gass. Ved slike innpakningsmaterialer kan imidlertid ikke gjenn-omtrengningsevnen innstilles, idet materialet enten er gasstett eller gjennomtrengbart. two-layer cover layer, one layer which is gas-tight and can be torn away to expose the second layer which is permeable to gas. With such wrapping materials, however, the permeability cannot be set, as the material is either gas-tight or permeable.
Formålet med oppfinnelsen er å frembringe en folie for inn-pakning som kan benyttes som sådan for innpakking av ost under behandlingen og lagringen av denne i forholdsvis lang tid, uten at det kreves ytterligere utstyr eller behandlingstrinn. The purpose of the invention is to produce a foil for wrapping which can be used as such for wrapping cheese during processing and storing it for a relatively long time, without requiring additional equipment or processing steps.
Emba1lasjefolien ifølge o<p>pfinnelsen erkarakterisert vedat den gas sgjennomtrengbare folien er i det minste delvis forsynt med et vesentlig gasstett belegg som eventuelt kan belegges ytterligere med en folie eller et sjikt som er gassgjennomtreng-bart. The packaging foil according to the invention is characterized in that the gas-permeable foil is at least partially provided with a substantially gas-tight coating which can optionally be further coated with a foil or a layer which is gas-permeable.
Formålet med oppfinne]sen er å innstille den totale gjennom-trengningsevnen for gass til fol ielaminatet på det ønskete nivå. The purpose of the invention is to set the total permeability for gas to the foil laminate at the desired level.
Overtrekket består fortrinnsvis av et sjikt av lakk, metall eller plast. Et slikt overtrekk kan fremstilles i form av et stripet eller rutet mdnster på folien. Det er imidlertid mulig The cover preferably consists of a layer of lacquer, metal or plastic. Such a covering can be produced in the form of a striped or checkered pattern on the foil. However, it is possible
å fremstille andre mønster eller å belegge en del av folien med i to produce other patterns or to coat part of the foil with i
overtrekk, idet resten blir holdt ubelagt.cover, while the rest is kept uncoated.
Embal las j ef ol ien kan for eksempel være fremstilt på^f dl gende måte: orientert polypropén blir delvis vakuum-meta 11 i sert med aluminium og en polyetenfolie klebelaminert over dette. Orientert polypropén og polyeten er lett gjennomtrengbare for gasser, omtrent ti ganger for høyt for osteemba11 asje. Gjennom-trengningsevnen for gass kan reduseres effektivt til tilnærmet null ved hjelp av vakuum-metalli sering. I det nevnte tilfellet ble foreksempel 90% av overflatearealet metallisert for å senke;emballasjematerialets totale permeabilitet til en tidel. Metalliseringen ble i eksempelet utført i lengderetningen på The packaging can, for example, be produced in the following way: oriented polypropylene is partially vacuum-meta 11 coated with aluminum and a polyethylene foil adhesively laminated over this. Oriented polypropylene and polyethylene are easily permeable to gases, about ten times too high for cheese packaging. The gas permeability can be effectively reduced to almost zero by means of vacuum metallization. In the aforementioned case, for example, 90% of the surface area was metallized to lower the total permeability of the packaging material to a tenth. In the example, the metallization was carried out in the longitudinal direction of
en slik måte at en klar, transparent gassgjennomtrengbar stripe .ble gjentatt med mellomrom på 30 mm. Tilsvarende virkning kan oppnås ved tett pvds-gass på samme måten. such a way that a clear transparent gas permeable strip .was repeated at intervals of 30 mm. A similar effect can be achieved with dense pvds gas in the same way.
Den nevnte stripete filmen kan deretter lamineres på folien, for eksempel av polypropén eller polyeten, på en slik måte at metalliseringen eller lakken vil være plassert mellom filmene for å beskytte lakken eller aluminiseringen. Ved å laminere på de nevnte folier vil det ferdige produkt også gjures sømbart. The said striped film can then be laminated on the foil, for example of polypropylene or polyethylene, in such a way that the metallization or varnish will be located between the films to protect the varnish or aluminization. By laminating the aforementioned foils, the finished product will also be made sewable.
Embal las j emater ial et kan også fremstilles ved å lakkere bgfaluminisere de ferdige laminerte f ol iekombi nas i oner etterpå. 1 dette tilfelle må lakksjiktet eller det vakuum-metalliserte sjiktet beskyttes med et g j ennomtrengbart. beskyttel sesovertrekk som er motstandsdyktig mot rifter. Packaging material can also be produced by varnishing and aluminizing the finished laminated foil combinations afterwards. In this case, the varnish layer or the vacuum-metallized layer must be protected with a permeable. protective cover that is resistant to tears.
Det er ovenfor nevnt noen få eksempler på realisering av oppfinnelsen, som er aktuelle nå. Det skulle imidlertid være klart, at enhver folie med forholdsvis høy giennomtrengbarhet for gass og som benyttes for innpakking, kan brukes som basis-folie, idet denne basisfolien blir forsynt med egnet overtrekk som senker denne permeabiliteten. A few examples of realization of the invention, which are relevant now, have been mentioned above. It should be clear, however, that any foil with a relatively high gas permeability and which is used for packaging can be used as a base foil, as this base foil is provided with a suitable cover which lowers this permeability.
