Seturile pe care le list\u0103m nu sunt prev\u0103zute cu sigiliu de garan\u021bie. Dac\u0103 produsul dumneavoastr\u0103 necesit\u0103 dovada vizibil\u0103 a primei deschideri, planifica\u021bi separat acest aspect, de exemplu cu o band\u0103 termocontractibil\u0103 sau cu un sigiliu exterior pe cutia de carton, sau alege\u021bi un alt tip de \u00eenchidere.<\/p>\n
Flaconul face parte din test la fel. Dopul, capacul \u0219i g\u00e2tul trebuie s\u0103 func\u021bioneze \u00eempreun\u0103, a\u0219a c\u0103 testa\u021bi \u00eentotdeauna cu flaconele reale pe care le ve\u021bi umple, nu cu un e\u0219antion cu aspect similar.<\/p>\n DIN18 este denumirea uzual\u0103 pentru aceast\u0103 dimensiune a g\u00e2tului, dar sticla este un produs turnat, iar g\u00e2turile variaz\u0103 \u00een limitele toleran\u021bei. \u00cenainte de testare, verifica\u021bi c\u0103 flaconele \u0219i dopurile sunt destinate aceluia\u0219i finisaj. Flaconele noastre flacoane cu picur\u0103tor DIN18\/GL18<\/a> sunt o potrivire tipic\u0103 pentru dopurile descrise aici.<\/p>\n Lua\u021bi un e\u0219antion de flacoane din mai multe cutii de carton, dac\u0103 este posibil. Dac\u0103 o cutie provine dintr-un lot de sticl\u0103 diferit, ve\u021bi observa din timp orice diferen\u021b\u0103.<\/p>\n Efectua\u021bi acest lucru pe o mas\u0103 de lucru curat\u0103, sub lumin\u0103 bun\u0103, \u00eenainte de umplere.<\/p>\n Introdu un dop \u00eentr-un flacon gol, manual, apoi apas\u0103-l complet p\u00e2n\u0103 la cap\u0103t. Observ\u0103 dac\u0103 intr\u0103 u\u0219or \u0219i se opre\u0219te net sau dac\u0103 necesit\u0103 o for\u021b\u0103 neobi\u0219nuit\u0103. Apoi \u00eentoarce flaconul \u0219i rostogole\u0219te bila pe o suprafa\u021b\u0103 plan\u0103 \u0219i curat\u0103.<\/p>\n Ceea ce trebuie s\u0103 observi este o bil\u0103 care se rote\u0219te liber \u00een toate direc\u021biile, f\u0103r\u0103 zgomot de frecare \u0219i f\u0103r\u0103 blocaje. O bil\u0103 care se rote\u0219te doar pe o parte indic\u0103 de obicei reziduuri \u00een loca\u0219 sau un dop care nu a fost a\u0219ezat complet.<\/p>\n O potrivire uscat\u0103, f\u0103r\u0103 produs, \u00ee\u021bi arat\u0103 doar geometria. Doar o umplere cu produsul real \u00ee\u021bi arat\u0103 performan\u021ba. Formulele roll-on variaz\u0103 de la uleiuri fluide p\u00e2n\u0103 la seruri \u0219i geluri mai groase, iar curgerea spre bil\u0103 difer\u0103 mult \u00eentre ele.<\/p>\n P\u0103streaz\u0103 formula constant\u0103 \u00een aceste teste. Dac\u0103 inten\u021bionezi s\u0103 modifici v\u00e2scozitatea, s\u0103 adaugi uleiuri esen\u021biale \u00eentr-un procent mai mare sau s\u0103 schimbi uleiul purt\u0103tor, repet\u0103 testele. Unii ingredien\u021bi pot afecta piesele din plastic \u00een timp, deci un test scurt nu \u00eenlocuie\u0219te un studiu de stabilitate mai lung cu propriul t\u0103u produs.<\/p>\n Capacul ar trebui s\u0103 se \u00eenfileteze u\u0219or \u0219i s\u0103 se str\u00e2ng\u0103 p\u00e2n\u0103 la o oprire ferm\u0103. Verific\u0103 s\u0103 nu se \u00eenfileteze gre\u0219it, s\u0103 nu lase un spa\u021biu la marginea de jos \u0219i s\u0103 poat\u0103 fi deschis de clientul \u021bint\u0103 f\u0103r\u0103 unelte. Dac\u0103 folose\u0219ti capsare automat\u0103, trece unit\u0103\u021bile de test prin ma\u0219in\u0103 \u0219i compar\u0103-le cu cele str\u00e2nse manual. Pentru ajutor la alegerea echipamentului, consult\u0103 articolul nostru despre ma\u0219inile de capsare semiautomate \u0219i automate.<\/p>\n Dac\u0103 folose\u0219ti \u0219i capace cu filet \u00een alte produse din gama ta, merit\u0103 s\u0103 verifici capacele FortiLock<\/a> pentru a asigura consisten\u021ba \u00eentre liniile de produse.<\/p>\n Write down the bottle lot, the plug and cap lot, the formula and batch, the date, the equipment used and the result of each check. If a problem comes up months later, this record makes it much easier to see whether it was the glass, the closure or the filling method. See also our checklist on DIN18 parts compatibility and our overview of GuardSeal plugs<\/a>, which covers the other plug styles we supply.<\/p>\n If you are switching bottle supplier, changing formula, or moving from hand filling to a machine, order samples and run the steps above before placing a carton order. It costs little and avoids pallets of unusable stock.<\/p>\n No. The sets described here use a non-tamper-evident PP cap. If you need tamper evidence, add an outer seal or choose a different closure type.<\/p>\n Only if the necks are the same DIN18 finish and a fit test passes. Always test with the exact bottle you intend to fill.<\/p>\n At minimum 24 hours in upright, inverted and side positions, using your actual formula. For long shelf-life products, add a longer stability test of your own.<\/p>\n Choose the color that suits your label and brand. The function is the same, so black and white caps can be tested together as one family.<\/p>\n![\"Row](\"https:\/\/www.packaging.si\/wp-content\/uploads\/2026\/11\/row-of-amber-glass-bottles-ready-for-filling-and-closure-testing-1024x682.jpg\")
