PROCEDIMENTO PER LA PRODUZIOME DI CARTA RICICLABILE IMPERMEABILE ALLA CERA, IN PARTICOLARE PER LA REALIZZAZIONE DI INVOLUCRI IMPERMEABILI ECOCOMPATIBILI PER CERI VOTIVI, PROCEDURE FOR THE PRODUCTION OF RECYCLABLE PAPER WATERPROOF TO WAX, IN PARTICULAR FOR THE REALIZATION OF WATERPROOF ECOCOMPATIBLE ENVELOPES FOR VOTIVE WAXES,
DESCRIZIONE DESCRIPTION
La presente invenzione riguarda il settore della lavorazione della carta, ed in particolare concerne un procedimento per ottenere della carta impermeabile alla cera, utilizzabile nella produzione di ceri votivi. The present invention relates to the paper processing sector, and in particular it concerns a process for obtaining paper impermeable to wax, which can be used in the production of votive candles.
Più specificamente, l'invenzione è relativa ad un procedimento di lavorazione della carta, preferibilmente, ma non esclusivamente, per la realizzazione di ceri votivi, che permette di ottenere un rivestimento di carta che, pur essendo impermeabile alla cera liquida, risulta essere totalmente riciclabile. More specifically, the invention relates to a paper processing process, preferably, but not exclusively, for the production of votive candles, which allows to obtain a paper coating which, although impermeable to liquid wax, is totally recyclable. .
Sono note dalla tecnica alcune soluzioni, tuttora in uso, per la produzione di ceri votivi. Ad esempio è ben noto l'utilizzo di involucri in plastica per contenere la cera liquida quando il cero è acceso. Questa soluzione presenta lo svantaggio di avere un costo elevato, dovuto alla plastica utilizzata, che aumenta notevolmente qualora si volessero produrre ceri ad alto impatto visivo, vista la necessità di operare su un supporto plastico per stampare a applicare delle rappresentazioni grafiche. Some solutions, still in use today, for the production of votive candles are known from the art. For example, the use of plastic wrappers to contain liquid wax when the candle is lit is well known. This solution has the disadvantage of having a high cost, due to the plastic used, which increases considerably if you want to produce candles with a high visual impact, given the need to operate on a plastic support to print and apply graphic representations.
Al fine di superare gli svantaggi legati all'utilizzo di questi involucri in plastica, nel recente passato, si è sperimentata con successo l'introduzione di rivestimenti in carta. In order to overcome the disadvantages associated with the use of these plastic wrappers, in the recent past, the introduction of paper coatings has been successfully experimented with.
L'impiego di questo tipo di rivestimenti ha comportato la necessità di utilizzare delle tecniche di plastificazione della carta stessa, al fine di evitare fuoriuscite di cera liquida durante la combustione dei ceri dotati di tali rivestimenti. Tale soluzione favorisce sicuramente la produzione di ceri decorati ad alto impatto visivo, grazie all'utilizzo della stampa tipografica, che ha una semplicità di attuazione e costi notevolmente contenuti rispetto alla plastica. The use of this type of coatings has entailed the need to use plasticization techniques of the paper itself, in order to avoid liquid wax leaks during the combustion of the candles equipped with such coatings. This solution certainly favors the production of decorated candles with a high visual impact, thanks to the use of typographic printing, which has a simplicity of implementation and costs significantly lower than plastic.
Purtroppo però, il processo di plastificazione rende questi involucri cartacei non riciclabili. Unfortunately, however, the lamination process makes these paper wrappers non-recyclable.
Scopo principale del trovato, è quello di superare 1 suddetti problemi, fornendo una procedura di lavorazione attraverso cui il supporto cartaceo viene reso impermeabile alla cera liquida, e perciò in grado di evitare fuoriuscite di questa durante la combustione del cero, senza però ricorrere al processo di plastificazione della carta e quindi permettendo di ottenere un prodotto totalmente riciclabile a fine vita. The main purpose of the invention is to overcome the aforementioned problems, providing a working procedure through which the paper support is made impermeable to the liquid wax, and therefore capable of preventing the latter from leaking during the burning of the candle, without however resorting to the process plasticization of the paper and therefore allowing to obtain a totally recyclable product at the end of its life.
Ciò è stato ottenuto, secondo l'invenzione, prevedendo un procedimento in cui la carta utilizzabile per realizzare l'involucro cartaceo è trattata con una doppia verniciatura con filtro di protezione agli UV, applicata su entrambi i lati, che rende la carta totalmente impermeabile e riciclabile. This has been achieved, according to the invention, by providing a process in which the paper that can be used to make the paper envelope is treated with a double coating with a UV protection filter, applied on both sides, which makes the paper totally waterproof and recyclable.
Una migliore comprensione dell'invenzione si avrà con la seguente descrizione dettagliata e con riferimento ai disegni allegati che illustrano, a puro titolo esemplificativo e non limitativo, una preferita forma di attuazione del trovato. A better understanding of the invention will be obtained with the following detailed description and with reference to the attached drawings which illustrate, purely by way of non-limiting example, a preferred embodiment of the invention.
Nei disegni: In the drawings:
la figura 1 mostra schematicamente, un esempio (non limitativo) di flusso di produzione secondo il procedimento oggetto della presente invenzione. Figure 1 schematically shows a (non-limiting) example of a production flow according to the process object of the present invention.
L'invenzione consiste sostanzialmente in un procedimento di trattamento della carta volto a renderla impermeabile alla cera liquida, in cui i supporti cartacei vengono stampati in quadricromia ed in modalità offset. Secondo una caratteristica peculiare del trovato, una volta stampata la carta, prima del taglio, su di essa viene applicato su ambo i lati, quindi sia fronte che retro, uno speciale finisher trasparente ad acqua con un filtro protettivo agli uv che rende vantaggiosamente la carta impermeabile alla cera liquida ed autoestinguente in caso di combustione. The invention substantially consists of a paper treatment process aimed at making it impermeable to liquid wax, in which the paper supports are printed in four-color process and in offset mode. According to a peculiar feature of the invention, once the paper has been printed, before cutting, a special transparent water-based finisher is applied on both sides, therefore both front and back, with a UV protective filter which advantageously renders the paper impermeable to liquid wax and self-extinguishing in case of combustion.
E' importante notare che, secondo l'invenzione, le vernici usate per la stampa e detto finisher trasparente non contengono pigmenti a base di composti di cadmio, piombo, mercurio, cromo esavalente, se non come semplici impurezze, in quantità comunque inferiori alle 100 ppm. Ciò comporta vantaggiosamente che gli involucri realizzati con la carta trattata col procedimento fin qui descritto possano essere regolarmente smaltiti, a fine utilizzo, mediante la raccolta differenziata nel comparto "carta e cartone". It is important to note that, according to the invention, the paints used for printing and said transparent finisher do not contain pigments based on compounds of cadmium, lead, mercury, hexavalent chromium, if not as simple impurities, in quantities in any case lower than 100 ppm. This advantageously entails that the envelopes made with the paper treated with the process described up to now can be regularly disposed of, at the end of use, by means of separate collection in the "paper and cardboard" compartment.
A questo riguardo, è opportuno precisare che le condizioni del substrato di stampa giocano un ruolo importante e, sebbene alcuni componenti della vernice non siano facilmente biodegradabili, la loro proporzione di peso rispetto al prodotto stampato finale é molto bassa rispetto al substrato. In this regard, it should be noted that the conditions of the printing substrate play an important role and, although some components of the varnish are not readily biodegradable, their weight proportion with respect to the final printed product is very low compared to the substrate.
Ne consegue che la grammatura dalla carta gioca un ruolo fondamentale, non solo per la possibilità di applicare la tecnica di doppia verniciatura UV, ma anche perché consente di stabilire un rapporto di peso tra carta e stampa 4 finisher adatto a renderlo smaltibile ed ecocompatibile. It follows that the weight of the paper plays a fundamental role, not only for the possibility of applying the double UV coating technique, but also because it allows you to establish a weight ratio between paper and print 4 finisher suitable to make it disposable and environmentally friendly.
A questo riguardo secondo l'invenzione si è individuata una grammatura minima per la carta, al fine di rendere applicabile il metodo e di ottenere i vantaggi precedentemente indicati: tale grammatura deve essere pari o superiore a 100 grammi per metro quadrato, preferibilmente 400 g/mq. In this regard, according to the invention, a minimum weight for the paper has been identified, in order to make the method applicable and to obtain the previously indicated advantages: this weight must be equal to or greater than 100 grams per square meter, preferably 400 g / sqm.
Nella preferita forma di attuazione del trovato che si descrive, un esempio di finisher utilizzabile è: Vernice UV per Thesis 201005/v50, vernice ad essicazione GV da utilizzare su elemento verniciatore "thesis", vernice da sovrastampa UV adatta alla stampa su carta e cartone. In the preferred embodiment of the invention described, an example of usable finisher is: UV varnish for Thesis 201005 / v50, GV drying varnish to be used on "thesis" varnish element, UV overprint varnish suitable for printing on paper and cardboard .
Una volta preparati i supporti con il metodo sopra descritto, la realizzazione di ciascun involucro per i ceri viene effettuata con le note modalità, applicando meccanicamente un fondello inferiore in alluminio, facendo si l'involucro assuma la tradizionale forma cilindrica. Once the supports have been prepared with the method described above, the realization of each casing for the candles is carried out with the known methods, mechanically applying a lower aluminum bottom, making the casing assume the traditional cylindrical shape.
In questo innovativo contenitore, così ricavato, viene introdotto il cero e viene applicata superiormente una cupola cava in alluminio, prodotto cosi rifinito è pronto per la commercializzazione e l'utilizzo. In this innovative container, thus obtained, the candle is introduced and a hollow aluminum dome is applied to the top, the finished product is ready for marketing and use.
