Pakkauskalvon tai muun pinnan kitkapinta - Friktionsyta för förpackingsfolie eller annan yta 5Friction surface of packaging film or other surface - Friktionsyta för förpackingsfolie eller annan yta 5
Keksintö koskee kitkakalvoa, jossa muovista, paperista tai muusta materiaalista olevan kalvon päällä on pistemäinen, verkkomainen tai muun kuvioinen kitkapinta.The invention relates to a friction film in which a film made of plastic, paper or other material has a punctate, reticulated or other patterned 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 The poor stackability of poorly stackable packages is now often avoided by making the cardboard or other supporting material an angular outer package, which naturally increases the cost considerably.
15 Tunnetuista kitkakalvoista tarramaisen pinnan lisääminen on usein kallista, koska tarrapintaa tarvitaan verraten paljon. Pölyisissä tiloissa tarrapinta täyttyy epäpuhtauksista ja menettää hyvät kitkaominaisuutensa. Tarrapintainen pakkauskalvo on vaikea pakata ja käyttää.15 Of the known friction films, adding a label-like surface is often expensive because a relatively large amount of label surface is required. In dusty rooms, the adhesive surface is filled with impurities and loses its good friction properties. The 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. Tällainen valmistus-25 tapa on kuitenkin kallis ja se soveltuu vain hyvin rajoitetuille kalvotyypeille. 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.By spraying a shred made of the same plastic at the stage of manufacturing a plastic film, even without glue, a friction film having both good friction values and good mechanical resistance under different conditions is obtained. However, this method of preparation is expensive and only suitable for very limited film types. If such a film is present in all stacked packages, it is difficult to bond the top packages of the stack together, even by gluing a film on top of them, because the plastic pieces of such a friction film interfere with the bonding of the bonding film.
Keksinnön perusideana on välttää em. haitat. Keksinnön mukaiselle kitkakalvolle on tunnusomaista rasterointimenetel-mällä aikaansaatu kuumasulatepinnoite, joka on edullisim-35 millään vain n. 3 g/m2. Kitkakalvo on lyhyen jäähdytyksen jälkeen valmis tuote, eikä se edellytä liuotteiden haihdu-tuslinjaa tai kallista pakkaustapaa, kuten tarramaisilla 2 82820 aineilla päällystetyt kitkapinnat. Tuotteessa ei myöskään ole haihtuvia aineita, kuten dispersioliiman liuottimia.The basic idea of the invention is to avoid the above-mentioned disadvantages. The friction film according to the invention is characterized by a hot melt coating obtained by a screening method, which is most preferably in any case only about 3 g / m 2. The friction film is a finished product after a short cooling and does not require a solvent evaporation line or an expensive packaging method, such as friction surfaces coated with adhesive-like 2,82820 materials. The product also does not contain volatile substances such as dispersion adhesive solvents.
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. Elintarvikepussien pinoaminen on ilman kitkakalvoa vaikeaa, ja tuotteet rikkoutuvat pudotes-10 saan. Kalvoa voidaan käyttää sellaisenaan kuljetuksissa liukuesteinä.Since the friction film according to the invention is very advantageous, it can also be used on large packages of cheap substances, such as large food packages, fertilizer sacks, timber hoods, raw material sacks and bulk packages. Stacking food bags is difficult without a friction film, and the products break into the drop-10. The film can be used as such in transports as non-slip devices.
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.With the product according to the invention, the filling of the inner bag during filling can be prevented during the filling of the double bag, and the mouth parts of both bags can be re-glued by reheating the same coating only for a short distance, and do not even require mangling because of the large contact surface.
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. Kuu-masulatteen levitysyksikkö voi olla painokoneen osana tai sen jatkeena, jolloin tuotantokustannusten lisäys kitkapinnan saamiseksi on varsin pieni.Since the coating according to the invention is obtained by a screening method or the like, the film can be coated only to the desired extent, whereby costs can be further reduced and thus also text can be printed on the same film after making a friction surface. made by blowing a piece of plastic onto a plastic film at the manufacturing stage. The hot melt application unit can be part of an printing machine or an extension thereof, whereby the increase in production costs to obtain a friction surface is quite small.

Termoplastisen sulatteen kiinnittäminen pakkauskalvoon on sinänsä tunnettu ja selostettu mm. suomalaisessa patentissa nro 71263.The attachment of the thermoplastic melt to the packaging film is known per se and has been described e.g. in 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. Pussipakkauksissa ei edes aikaansaada 3 82820 sileitä pintoja, jotka olisivat vastakkain. 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.35 The coefficient of friction of perfectly smooth plastic films of some grades is usually high, but even small impurities such as cement dust, aggregate dust or pollen drop the friction sharply. The bag packs do not even provide 3,82820 smooth surfaces facing each other. The friction increases at least twice when the coated film is against the uncoated film, as shown by the innovation, and when the two friction surfaces are opposite, the total friction is even much better.
Termoplastisen sulatteen täyteaineena voidaan käyttää esi-10 merkiksi korundia, kun pakkauskalvo on paksu, tai esimerkiksi kalsiumsulfiittia, magnesiumsilikaattia, piidioksidia tai näiden kombinaatioita; täyteaineet ovat sinänsä tunnettuja esimerkiksi US patentista 3,691,120.As the filler of the thermoplastic melt, for example, corundum can be used when the packaging film is thick, or, for example, calcium sulfite, magnesium silicate, silica, or combinations thereof; fillers are known per se, for example from U.S. Patent 3,691,120.
15 Rasterointipinta voidaan tunnetulla menetelmällä tehdä erilaiseksi pakkauksen yläpinnalle ja alapinnalle, joiden kuvioiden yhteisvaikutuksena saadaan edullinen sidos.By means of a known method, the screening surface can be made different on the upper and lower surfaces of the package, the patterns of which combine to give a favorable bond.
Mikäli pakkauskalvo on arka, valitaan sellainen rasterointi-20 pisteen muoto, joka ei riko kalvon pintaa, esimerkiksi puolipallon muotoisia pisteitä tasaisena kuviona.If the packaging film is delicate, a shape of the raster-20 point is selected which does not break the surface of the film, for example hemispherical points in a flat pattern.
