Boja prstena i ostatak konstrukcije isti su.<\/p>\n<p>Ovo je dizajnerski izbor, a ne tehni\u010dki. Ipak, vrijedi razmotriti nekoliko prakti\u010dnih to\u010daka:<\/p>\n<ul>\n<li>Bijeli mje\u0161\u010di\u0107 daje svjetliji, \u010di\u0161\u0107i izgled, ali se lak\u0161e vide mrlje ako je proizvod taman ili masan.<\/li>\n<li>Crni mje\u0161\u010di\u0107 prikriva mrlje i pristaje uz tamnija ili presti\u017enije izgledaju\u0107a pakiranja.<\/li>\n<li>Provjerite da boja mje\u0161\u010di\u0107a dobro izgleda u kombinaciji s etiketom, kutijom i bojom bo\u010dice, a ne samo s prstenom.<\/li>\n<\/ul>\n<h2>Korak 4: Odaberite zavr\u0161nu obradu prstena<\/h2>\n<p>Boja prstena najvidljiviji je dio kapaljke. Asortiman dolazi u tri sjajne aluminijske zavr\u0161ne obrade:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.packaging.si\/hr\/kategorija-proizvoda\/kapaljke-alu\/kapaljke-alu-gold-day\/\">ALU Gold Day<\/a> i ALU Gold Night za topao, klasi\u010dan izgled.<\/li>\n<li>ALU Silver Day i ALU Silver Night za neutralan, tehni\u010dki izgled.<\/li>\n<li>ALU Rose Day i ALU Rose Night za mek\u0161i, topliji metalni ton.<\/li>\n<\/ul>\n<p>Ako preferirate nesjajnu povr\u0161inu, zasebni ALU Matte asortiman mo\u017eda \u0107e vam bolje odgovarati.

Metalne boje na ekranu izgledaju druga\u010dije nego u ruci.<\/p>\n<h2>Korak 5: Obi\u010dna ili graduirana pipeta<\/h2>\n<p>Obi\u010dne pipete jednostavnija su opcija i \u010desto su dovoljne kada kupac doziranje odre\u0111uje na oko ili doza nije mjerena. Graduirane pipete imaju skalu koja poma\u017ee pri mjerenoj uporabi. Ako odaberete graduiranu, u specifikaciji definirajte sljede\u0107e:<\/p>\n<ul>\n<li>Koji volumen skala treba prikazivati i odgovara li uputama za uporabu.<\/li>\n<li>Je li skala prihvatljiva prema va\u0161im zahtjevima kvalitete i ozna\u010davanja.<\/li>\n<li>Trebate li dokumentaciju za otisnute skale.

NBR je \u010dest izbor za ulja, ali nisu sve formule jednake. Jaka otapala, neke mje\u0161avine eteri\u010dnih ulja i proizvodi s visokim udjelom alkohola mogu tijekom vremena utjecati na gumu. Prije narud\u017ebe u ve\u0107oj koli\u010dini:<\/p>\n<ol>\n<li>Napunite nekoliko uzora\u010dkih bo\u010dica stvarnim proizvodom.<\/li>\n<li>\u010cuvajte ih s postavljenom kapaljkom, uklju\u010duju\u0107i barem jednu pohranjenu na boku ili naopako ako je to realan uvjet.<\/li>\n<li>Inspect the teat for swelling, stickiness, deformation or colour change at intervals that match your intended shelf life.<\/li>\n<\/ol>\n<p>This is a simple in-house check. It does not replace your own stability work, but it catches obvious incompatibility early.<\/p>\n<h2>Step 7: Plan for the filling and capping line<\/h2>\n<p>Aluminium collars have a shiny surface that can scuff. A few habits help protect the finish:<\/p>\n<ul>\n<li>Use capping heads or chucks that grip without hard metal contact, and check them for wear.<\/li>\n<li>Run a small trial batch to set the tightening force. Too little can cause leaks; too much can mark the collar or stress the bottle.<\/li>\n<li>Keep droppers in their bags until they are needed, and avoid loose piles that let collars rub against each other.<\/li>\n<li>Check the pipette tip against the bottle shoulder during the first assembled samples.<\/li>\n<\/ul>\n<p>For small runs, hand capping works if the operator is consistent. For larger runs, see our articles on semi-automatic and automatic capping machines.<\/p>\n<h2>Step 8: Write the specification<\/h2>\n<p>Once the above is decided, put it all in one line. A complete specification for an order could look like this:<\/p>\n<ul>\n<li>Bottle: 30 ml, DIN18 (GL18) neck<\/li>\n<li>Dropper: ALU Gold Day, white NBR teat, gold aluminium collar with PP inner part<\/li>\n<li>Pipette: 77 mm straight-tip glass, graduated<\/li>\n<li>Quantity: number of cartons<\/li>\n<li>Packing: any special requirement, such as individual bags<\/li>\n<\/ul>\n<p>Share this with your supplier and your own incoming inspection team. It becomes your reference when checking deliveries.<\/p>\n<h2>Uobi\u010dajene pogre\u0161ke koje treba izbjegavati<\/h2>\n<ul>\n<li>Ordering by collar colour alone and checking the pipette length later.<\/li>\n<li>Assuming all bottles of the same volume have the same height.<\/li>\n<li>Approving a collar colour from a screen image.<\/li>\n<li>Skipping a compatibility trial with the real formula.<\/li>\n<li>Not defining plain or graduated in the purchase order.<\/li>\n<\/ul>\n<h2>\u010cesta pitanja<\/h2>\n<h3>Do all ALU droppers fit the same bottle neck?<\/h3>\n<p>Yes. All items in the ALU range use a DIN18 (GL18) thread. The pipette length changes with bottle volume, so check that as well.<\/p>\n<h3>What is the difference between Day and Night versions?<\/h3>\n<p>Day versions have a white NBR teat and Night versions have a black NBR teat. Collar colours and construction are otherwise the same.<\/p>\n<h3>Can I order a plain or a graduated pipette?<\/h3>\n<p>Both options are available for the ALU range. State your choice clearly when you order.<\/p>\n<h3>Can I get samples before placing a larger order?<\/h3>\n<p>Yes.
