Pakkauskalvon tai muun pinnan kitkapinta - Friktionsyta för förpackingsfolie eller annan yta 5 Packaging film, or other surface of the friction surface - Friktionsyta for förpackingsfolie surface of eller give 5

Keksintö koskee kitkakalvoa, jossa muovista, paperista tai muusta materiaalista olevan kalvon päällä on pistemäinen, verkkomainen tai muun kuvioinen kitkapinta. The invention relates to friction film comprising a plastic, paper or other material on the film is a point-like, net-like or other pattern friction surface.

10 Huonosti toistensa päällä pysyvien pakkausten heikkoa pinot-tavuutta vältetään nykyisin usein siten, että kartongista tai muusta tukevasta aineesta tehdään kulmikas ulkopakkaus, joka luonnollisesti lisää kustannuksia melkoisesti. 10 ill of each other on the permanent weak stacks of packages in profitability is currently often avoid such a way that the paperboard or other material is made to support the angled outer packaging, which, of course, adds to the cost considerably.

15 Tunnetuista kitkakalvoista tarramaisen pinnan lisääminen on usein kallista, koska tarrapintaa tarvitaan verraten paljon. 15 of the known friction film by the addition of tacky surface of the often expensive, because the label surface is required relatively much. Pölyisissä tiloissa tarrapinta täyttyy epäpuhtauksista ja menettää hyvät kitkaominaisuutensa. In dusty areas filled with self-adhesive surface impurities and loses the good frictional properties. Tarrapintainen pakkauskalvo on vaikea pakata ja käyttää. Self adhesive packaging film is difficult to pack and use.

Ruiskuttamalla muovikalvon valmistusvaiheessa samasta muovista tehtyä silppua saadaan jopa ilman liimaa sellaista kitkakalvoa, jolla on sekä hyvät kitka-arvot että hyvä mekaaninen kestävyys eri olosuhteissa. By injecting the plastic film at the manufacturing stage made of the same plastic shreds is obtained even without glue, a friction surface, which has both good adhesion values ​​and the high mechanical strength in different conditions. Tällainen valmistus-25 tapa on kuitenkin kallis ja se soveltuu vain hyvin rajoitetuille kalvotyypeille. Such a manufacturing method 25 is, however, expensive and suitable only very limited types of film. Jos tällainen kalvo on kaikissa pinotuissa pakkauksissa, on pinon ylimmät pakkaukset vaikea sitoa keskenään edes liimaamalla näiden päälle kalvoa, koska sellaisen kitkakalvon muovipalat haittaavat sidonta-30 kalvon kiinnittämistä. If such a film is all stacked packages is the top of the stack packages difficult to bind with each other even by gluing on top of the film since the film of friction plastic pads hinder the binding 30 the film.

Keksinnön perusideana on välttää em. haitat. The basic idea of ​​the invention is to avoid the above. disadvantages. Keksinnön mukaiselle kitkakalvolle on tunnusomaista rasterointimenetel-mällä aikaansaatu kuumasulatepinnoite, joka on edullisim-35 millään vain n. 3 g/m2. kitkakalvolle according to the invention is characterized by rasterointimenetel-kuumasulatepinnoite provided, which is most advantageous in any 35-only approx. 3 g / m 2. Kitkakalvo on lyhyen jäähdytyksen jälkeen valmis tuote, eikä se edellytä liuotteiden haihdu-tuslinjaa tai kallista pakkaustapaa, kuten tarramaisilla 2 82820 aineilla päällystetyt kitkapinnat. Friction film is after a short cooling of the finished product and does not require solvents evaporate lines are utilized, or an expensive packing method, such as 2 82 820 tacky substances coated with frictional surfaces. Tuotteessa ei myöskään ole haihtuvia aineita, kuten dispersioliiman liuottimia. The product does not have volatile substances, such as solvents, dispersion adhesive.

Koska keksinnön mukainen kitkakalvo on hyvin edullinen, 5 sitä voidaan käyttää myös halpojen aineiden suurten pakkausten päällä, kuten suurissa elintarvikepakkauksissa, lannoi-tesäkeissä, puutavaran hupuissa, raaka-ainesäkeissä ja bulkkitavarapakkauksissa. Since the friction foil according to the invention is very advantageous, 5 can also be used on the large packages of inexpensive materials, such as large food packaging, fertil-tesäkeissä, hoods timber, raw ainesäkeissä and bulkkitavarapakkauksissa. Elintarvikepussien pinoaminen on ilman kitkakalvoa vaikeaa, ja tuotteet rikkoutuvat pudotes-10 saan. Food is stacking the bags without friction film difficult, and the products are broken in pudotes-10 of them. Kalvoa voidaan käyttää sellaisenaan kuljetuksissa liukuesteinä. The film can be used as such for the transport of floating barriers.

Keksinnön mukaisella tuotteella voidaan kaksoispusssin täytössä estää sisäpussin valumisen täytön aikana, ja molempi-15 en pussien suuosat voidaan liimata samaa pinnoitetta uudelleen lämmittämällä vain lyhyeltäkin matkalta, eikä siinä edes tarvita mankelointia, koska kosketuspinta on suuri. The product according to the invention can be kaksoispusssin during filling to prevent drainage of filling the inner bag, and the two 15-en mouths of bags can be bonded again by heating the same coating only from short trip, it does not even need mangling, because the contact surface is large.

Koska keksinnön mukainen pinnoite on aikaansaatu rasteroin-20 timenetelmällä tai muulla senkaltaisella menetelmällä, voidaan kalvo pinnoittaa vain halutulta osin, jolloin kustannuksia voidaan edelleen pienentää ja näin myös mahdollistetaan tekstin painatus samalle kalvolle kitkapinnan tekemisen jälkeen, joka ei ole mahdollista esimerkiksi 25 sellaiselle kitkapinnalle, joka on tehty puhaltamalla valmistusvaiheessa muovisilppua muovikalvon päälle. Since the coating according to the present invention there is provided a rasteroin-20 methods, or any other similar method, a film can be coated on only a desired point, whereby the cost can be further reduced, and thus also allow the text printed on the same film after the friction surface of the award, which is not possible, for example, 25 to a friction surface, which is at the manufacturing stage of blowing plastic chopping on a plastic film. Kuu-masulatteen levitysyksikkö voi olla painokoneen osana tai sen jatkeena, jolloin tuotantokustannusten lisäys kitkapinnan saamiseksi on varsin pieni. Moon masulatteen spreading unit may be part of a printing press or as an extension to increase the production cost of obtaining the friction surface is quite small.

Termoplastisen sulatteen kiinnittäminen pakkauskalvoon on sinänsä tunnettu ja selostettu mm. The thermoplastic melt attachment to the packaging film is known per se and described for example. suomalaisessa patentissa nro 71263. Finnish Patent No. 71263.

35 Täysin sileiden eräiden muovilaatujen muovikalvojen kitka-kerroin on yleensä korkea, mutta pienetkin epäpuhtaudet, kuten sementtipöly, kiviainespöly tai siitepöly pudottaa kitkan voimakkaasti. 35 Completely smooth certain types of plastic films plastic friction coefficient is generally high, but even small impurities, such as cement dust, rock dust or pollen to drop sharply friction. Pussipakkauksissa ei edes aikaansaada 3 82820 sileitä pintoja, jotka olisivat vastakkain. The packaging bag does not even provide a 3 82 820 smooth surfaces, which are opposite each other. Kitka lisääntyy innovaation osoittamalla tavalla pinnoitetun kalvon ollessa 5 pinnoittamatonta kalvoa vasten ainakin kaksinkertaiseksi, ja kun kaksi kitkapintaa on vastakkain, on kokonaiskitka vielä tätäkin huomattavasti parempi. The friction increases as indicated by the innovation of the coated film being 5 against the uncoated film is at least two fold, and the two friction surfaces are facing each other, the total friction is even more greatly improved.

Termoplastisen sulatteen täyteaineena voidaan käyttää esi-10 merkiksi korundia, kun pakkauskalvo on paksu, tai esimerkiksi kalsiumsulfiittia, magnesiumsilikaattia, piidioksidia tai näiden kombinaatioita; The thermoplastic melt may be used as a filler pre-corundum mark 10 when the packaging film is thick, or, for example, calcium, magnesium silicate, silica, or combinations thereof; täyteaineet ovat sinänsä tunnettuja esimerkiksi US patentista 3,691,120. Sealants are known per se, for example, U.S. Patent No. 3,691,120.

15 Rasterointipinta voidaan tunnetulla menetelmällä tehdä erilaiseksi pakkauksen yläpinnalle ja alapinnalle, joiden kuvioiden yhteisvaikutuksena saadaan edullinen sidos. 15 Rasterointipinta can be made by a known method different from the upper surface and the lower surface of the package, which the interplay of the figures a preferable bond.

Mikäli pakkauskalvo on arka, valitaan sellainen rasterointi-20 pisteen muoto, joka ei riko kalvon pintaa, esimerkiksi puolipallon muotoisia pisteitä tasaisena kuviona. If the packing foil is sensitive, a form selected from the halftone-dot 20 that does not break the surface of the film, for example, hemispherical dots uniform pattern.
