Esillä oleva keksintö kohdistuu muovilaminaatista, jossa muovikerrokset liimalaminoidaan yhteen, ja paperista kuumasaumaamalla tehty pakkaukseen, joka on tarkoitus sulkea hermeettisesti ja jonka hermeettisyys voidaan todeta visuaalisesti värillisten kuumasaumojen avulla.The present invention relates to a plastic laminate in which the plastic layers are glued together and to a package made of paper by heat sealing, which is intended to be hermetically sealed and the hermeticity of which can be seen visually by means of colored heat seals.

Keksinnön mukainen pakkaus on lähinnä tarkoitettu sterilointiin, etupäässä sairaalasterilointiin. Sterilointipakkauksen tarkoituksena on mahdollistaa tuotteen steriloiminen pakattuna ja säilyttää sen steriliteetti steriloinnin jälkeen, pakkauksessa käytettyjen materiaalien sekä saumojen tulee olla niin tiiviitä, etteivät mikro-organismit pääse niiden läpi pakkauksen sisään.The package according to the invention is mainly intended for sterilization, primarily for hospital sterilization. The purpose of the sterilization package is to enable the product to be sterilized when packaged and to maintain its sterility after sterilization, and the materials and seams used in the package must be so tight that microorganisms cannot pass through the package.

Nykyään käytetään valkoista paperia ja värintöntä muovikalvoa tai -laminaattia. Tällöin kuitenkin saumojen hermeettisyyden toteaminen on erittäin vaikeata. Käytössä on myös värillistä paperia, mutta sen antama sauma-efekti on erittäin heikko. Värillistä kalvoa käy- 2 60843 tettäessä valmistus on hankalampaa kuin värjättäessä liimaa. Värillistä liimaa käytettäessä voidaan joustavasti käyttää kuhunkin pakkaus- ja sterilointitapaan parhaiten sopivat standardikalvot. Esillä olevan keksinnön tarkoituksena on aikaansaada sterilointipakkaus, josta voidaan visuaalisesti tarkastaa saumojen hermeettisyys ilman lisälaitteita tai testejä ja pakkausta hävittämättä.Today, white paper and colorless plastic film or laminate are used. In this case, however, it is very difficult to determine the tightness of the joints. Colored paper is also used, but its seam effect is very weak. When using a colored film, 2 60843 it is more difficult to manufacture than when dyeing an adhesive. When using colored adhesive, the standard films best suited for each method of packaging and sterilization can be flexibly used. It is an object of the present invention to provide a sterilization package from which the tightness of the seams can be visually inspected without additional equipment or tests and without destroying the package.

Keksinnölle on tunnusomaista se, että laminointiin käytetty liima on värillinen.The invention is characterized in that the adhesive used for lamination is colored.

Muovilaminaatti on yleensä orientoimaton tasokalvomenetelmällä valmistettu polypropeenikalvo ja orientoitu polyesterikalvo, jotka on liimalaminoitu yhteen. Käytetty liima värjätään sopivalla liimaan liukenevalla pigmentillä siten, että valmis kalvolaminaatti saa vaalean sävyn. Kuumasaumattaessa tämän kalvolaminaatin paperia vasten saumautuneet alueet muuttuvat tummemmiksi, jolloin saumautuneet alueet erottuvat selvästi ja voidaan visuaalisesti tarkastaa.The plastic laminate is generally a non-oriented flat film polypropylene film and an oriented polyester film glued together. The adhesive used is dyed with a suitable adhesive-soluble pigment so that the finished film laminate has a light shade. When heat-sealed against this paper laminate, the seamed areas become darker, allowing the seamed areas to stand out clearly and be visually inspected.

Keksinnön mukainen laminaatti valmistetaan kuivalaminoimalla kaksi tai useampia muovikalvoja yhteen. Liimana käytetään taipuisien muo-kalvojen laminointiin tarkoitettua liimaa, joka voi olla jokin 1-tai 2-komponenttinen polyesteri- tai polyuretaanityyppinen liima. Liimaan sekoitetaan väriainetta, joka voi olla jokin liukeneva orgaaninen (metalli)kompleksiväriaine.The laminate of the invention is made by dry laminating two or more plastic films together. The adhesive used is an adhesive for laminating flexible shaped films, which can be a 1-component or 2-component polyester or polyurethane type adhesive. The adhesive is mixed with a dye, which may be a soluble organic (metal) complex dye.

Edellä on esimerkkeinä pakkauskalvosta mainittu joitakin yleisesti jo käytössä olevia. On tietysti ilman muuta selvää, että peruskal-voina voidaan käyttää mitä tahansa sterilointiin soveltuvaa kalvoa kuten esim. polyeteeniä ja polyamidia.As examples of packaging film, some commonly used ones have been mentioned above. Of course, it is obvious that any film suitable for sterilization can be used as the base film, such as, for example, polyethylene and polyamide.
