Description
TARIFNAME BARIYER KAPLAMASINA SAHIP OLAN KAGIT YA DA KARTON AMBALAJ LAR Mevcut bulus, bir bariyer tabakasina sahip olan madeni yaga dayanikli, yeniden dönüstürebilen kagittan olusan bir kagit ya da karton ambalaj olup, C1 ila C4 alkil(met)akrilatlardan, asit monomerlerinden ve opsiyonel olarak akril nitrilden ve diger monomerlerden emülsiyon polimerizasyonu vasitasi ile üretilebilir olan bir kopolimer içeren bir sulu polimer dispersiyonun uygulanmasi suretiyle üretilebilmekte olup, içerisinde kopolimerin cam geçis sicakligi + 10 “C ila + 45 °C arasinda bulunur. Bariyer tab akasi ambalaj yüzeylerinin birisi üzerinde bulunabilir ya da bir çok tabakali ambalaj kaplamasinin çok sayidaki tabakalarindan birisini olusturabilir. DESCRIPTION PAPER OR CARDBOARD PACKAGING WITH BARRIER COATING The present invention is a mineral oil resistant, recyclable material having a barrier layer. A paper or cardboard package consisting of recyclable paper, C1 to C4 alkyl(meth)acrylates, acid monomers and optionally acryl nitrile and other containing a copolymer that can be produced from monomers by emulsion polymerization can be produced by applying an aqueous polymer dispersion, in which The glass transition temperature of the copolymer is between + 10 “C to + 45 °C.

Karton ambalajlar normal olarak yeniden dönüstürülmüs kagittan üretilirler. Basili kagit, özellikle gazete kagidi durumunda yeniden dönüstürülmüs kagit gazete baskisi için bilinen sekilde kullanilan baski boyalarindan madeni yag artiklarini içerebilir. Oda sicakliginda bile bu artiklarin uçucu kisimlari buharlasir ve gida maddesi ambalajlari durumunda kutu içine paketlenmis olan gida maddelerinde, örnegin makarna, bulgur, pirinç ya da kornflakes üzerinde üzerine çökelirler. Günümüzde kullanilan polimer folyolardan çogu iç torbalar da burada yeterli koruma sunmamaktadir. Zürich Kanton Laboratuarinin arastirmalarinda, yeniden dbnüstürülmüs kagittan ambalajlarin içerisine paketlenmis olan gida maddelerinin içerisinde madeni yag artiklari önemli miktarlarda tespit edilmistir. Uçucu madeni yag bilesimlerinde agirlikli olarak saglik açisindan zararli parafin ve naften türü hidrokarbonlar ve aromatik hidrokarbonlar, özellikle de 15 - 25 karbon atomuna sahip olanlar söz konusudur. Cardboard packages are normally produced from recycled paper. printed paper, Recycled paper known for newspaper printing, especially in the case of newsprint May contain mineral oil residues from printing inks used in this way. Even at room temperature this the volatile part of the residue evaporates and in the case of food packaging, it is put into the box. in packaged foodstuffs, for example on pasta, bulgur, rice or cornflakes they precipitate on. Most inner bags of polymer foils used today are also sufficient here. does not offer protection. In the researches of the Zürich Cantonal Laboratory, again In foodstuffs packaged in recycled paper packages mineral oil residues were detected in significant amounts. In volatile mineral oil compositions mainly harmful to health paraffin and naphthene type hydrocarbons and aromatic hydrocarbons, particularly those having 15 to 25 carbon atoms.
Bu nedenle gida maddelerinin madeni yag artiklari ile bir kontaminasyonu riskinin azaltilmasina yönelik bir ihtiyaç bulunmaktadir. Gida maddelerinin ambalajlanmasi için kartonlarin üretiminde gazete kagidinin yeniden dönüsümünden vazgeçilmesi olanagi bulunmaktadir. Bu ekolojik nedenlerden dolayi arzu edilmez ve yeni selülozlarin yeterli derecede miktarlarda kullanima hazir olmamasi nedeniyle uygulanamaz. Bir diger çözümde, gazete basimi için baski boyalarinda madeni yaglarindan vazgeçilmesidir. Bu ise teknolojik engellere takilmaktadir, Özellikle de kagit yüzeyi üzerine baskinin silme mukavemeti açisindan engel bulunur. Ambalaj alaninda sivi yaglara ve kati yaglara karsi bariyer kaplamalari bilesimleri tarif edilmistir. Polimerler sivi yagli substantlara karsi iyi bariyer 'Özellikleri gösterirler Fakat bu sekilde gaz formunda geçen maddelere karsi bir iyi bariyer etkisinin mutlara zorunlu olarak mevcut olmadigi görülmüstür, çünkü burada geçen maddelerin farkli nakil mekanizmalari söz konusu olur. Kati ve sivi yaglarda nakil elyaflarin üzerinden meydana gelmekte olup, içerisinde kilcal kuvvetler ve yüzey nemlendirilmesi bir rol oynar. Therefore, there is a risk of contamination of foodstuffs with mineral oil residues. There is a need to reduce For packaging of foodstuffs the possibility of dispensing with the recycling of newsprint in the production of cardboard are available. This is undesirable for ecological reasons and new celluloses are not sufficient. It cannot be applied because it is not ready for use in large quantities. In another solution, is the abandonment of mineral oils in printing dyes for newspaper printing. This is technological gets caught in obstacles, especially in terms of the wiping strength of the print on the paper surface. obstacle exists. Barrier coatings against oils and fats in the packaging area compositions are described. Polymers 'Properties of good barrier against oily substrates' However, in this way, they have a good barrier effect against substances passing in gaseous form. It has been seen that mutlara does not necessarily exist, because the substances mentioned here are different. transport mechanisms are involved. In solid and liquid oils, transport over the fibers occurs, in which capillary forces and surface moistening play a role.
Gaz formunda geçen maddelerdeki sorunlarda kilcal etki ve nemlendirme rol oynamaz, bunun yerine sorbsiyon, difüzyon ve gözeneklilik gözeneklilik önemli rol oynar. Ayrica hidrokarbonlarin kati ve sivi yaglari da farklidir, yani madeni yag bilesenlerinin kendi polaritesi ve bu sekilde bariyer tabakalarindan kendi difüzyon davranisi ile farklidirlar. Capillary effect and humidification do not play a role in the problems in gaseous substances, instead, sorption, diffusion and porosity play important roles. Moreover The solid and liquid oils of hydrocarbons are also different, that is, the mineral oil components themselves they differ by their polarity and thus their diffusion behavior from the barrier layers.
Mevcut bulusun amaci, madeni yagla kirlenmis yeniden dönüstürülmüs kagidin kullanimina ragmen uçucu madeni yag bilesenleri ile ambalaj malzemesinin bir kontaminasyon riskinin azaltilmasidir. The aim of the present invention is to use recycled paper contaminated with mineral oil. Although there is a risk of contamination of the packaging material with the components of volatile mineral oil. is the reduction.
