Grasping complexity and acting proactively on sustainability is key to ensure successful compliance with packaging laws and avoid financial sanctions.

Extended Producer Responsibility Extended Producer Responsibility (EPR) rules vary from one country toanother. For example, in terms of the definition of the liable party in thepackaging supply chain, the related obligations (registration, reportingfrequency and deadline and financial contribution) and the penalties andrewards for packaging design. Depending on the country, a companydecides to comply with the EPR rules on its own by establishing a reverselogistics system (i.e.be self-compliant), or it is possible to register andtransfer its take-back obligations (collection and recovery of packagingwaste) to a Producer Responsibility Organization (PRO).If a companyopts for contracting with a PRO, in some countries several organizationsare active and in competition: choosing the right one is important, as thefees and reporting processes may vary from one organization to another. Labelling and marking requirements These requirements vary greatly among countries as well and there are nouniform rules.The Green Dot logo is an example of the complexity forbusinesses to remain compliant with labelling in many countries, as this logo is currently mandatory in Spain and Cyprus, encouraged in severalEU countries, and discouraged in other countries like France. National versus international compliance Compliance complexity further increases through the national evolutionsover time: between 2o19 and 2o21, there have been many changes Corrugated Machine regarding packaging obligations: e.g. new marking Corrugated Box Machine requirements in Italyand Portugal, an extended producer registration scope in Germany, or theintroduction of eco-modulation in the EPR fees system of Czech Republic.The changes will not stop here, with for instance the new upcoming obligation for 2o24 requiring all EU countries to ensure that EPRschemesare established for all packaging types.

Solutions for single-sided cardboard crushing and corrugated crushing after double-sided machine

(1) Broken single-sided cardboard Cause Analysis: 1. The pressure of the pressure roller is too large; 2. Corrugated paper has short fibers, no toughness and poor quality; 3. The gap between the upper and lower E flute corrugated roller is too small; 4. The preheating area is too large, and the corrugated paper loses water seriously; 5. The temperature of the corrugating roller is too high; 6. The middle and high heights of the corrugating roller are severely worn. In order to ensure the adhesion of the single-sided cardboard corrugated roller in the middle and increase the pressure of the pressure roller, it is easy to cause excessive pressure at both ends of the corrugating roller and cause the corrugated paper to be broken. Solution: 1. Generally, the pressure of the pressure roller should not exceed 2kPa. Under normal conditions of the equipment, as long as the corrugated paper and the lining paper are well bonded, the smaller the pressure, the better. In this way, the service life of the corrugating roller and the pressure roller can be prolonged, and it should be properly adjusted in actual production; 2. Replace corrugated paper; 3. Correct the gap between corrugated rollers; 4. Appropriately reduce the preheating area; 5. Reduce

6 keys to a good scraper to solve problems such as whitening and ink leakage

In the accessories of papermaking equipment, there are many small parts that seem inconspicuous but very important, and the scraper is one of them. Although the scraper is very inconspicuous, it has a crucial impact on the product quality for high-precision ink color printing technology. The pressure, sharpness, and contact position of the squeegee have an impact on the printing quality. According to actual needs, reasonable adjustment of these factors can solve many printing problems. 1. Correctly understand the scraper Nowadays, more and more printing machines use squeegee, so how to use the squeegee correctly is also very important. There are many printing presses in carton factories who always feel that the scraper is not easy to use, and it is not as easy to use as the original rubber roller. Is this because the scraper is not good or other reasons? Advantages of using a scraper: uniform inking, thin inking, fast cleaning of the anilox roller, water saving, etc. The printed fonts and patterns are cleaned, and the color is bright and saturated. The harm of improper use of the scraper: it will lead to the phenomenon of ink rod, white printing, ink leakage, uneven ink scraping, etc., which will seriously affect the quality of printed products. 2. The difference in habits leads to the problem of using the scraper: the maintenance is not in place The mesh number of the anilox roller using the scraper is generally much higher than that of the rubber roller, so the maintenance level of the anilox roller is relatively different. Because the rubber roller is inked, th

Attention|Peripheral heated corrugated rollers are equipped with high-speed corrugated lines, with outstanding advantages!

Attention|Peripheral heated corrugated rollers are equipped with high-speed corrugated lines, with outstanding advantages! The corrugating roller is a corrugated forming mold and a key component of the single-sided machine in the corrugated line, which directly affects the quality of the corrugated board. In the domestic corrugating roll manufacturing industry, the new peripheral heating corrugating roll developed and continuously improved by LLY PACK is gradually replacing the traditional heating corrugating roll, and has been successfully applied to the corrugating lines of various brands in mainland China, Taiwan, Europe and the United States. It is understood that there are two main heating methods for corrugated rollers, namely cavity heating and peripheral heating. Among them, although the cavity heating method once occupied the mainstream in the industry, it will cause the condensed water to adhere to the inner cavity wall of the corrugated roller, which prolongs the preheating time, reduces the heat transfer efficiency, and greatly affects the quality of corrugated cardboard and the production speed. Therefore, it is gradually eliminated by the industry. Compared with the traditional heated corrugated roller, the peripherally heated corrugated roller is completely different. Its unique design does not require a siphon, and there is no condensed water adhering to the inner cavity wall. The shortened heat time not only improves the heat transfer efficiency, reduces the production energy consumption, but also prolongs the service life.

Come regolare con precisione l'inchiostro a colori spot per la stampa offset? Ti dirò il trucco!

Nella stampa offset a foglio, la stampa a tinte piatte è un processo comune, che ha stabilità e uniformità del colore ineguagliate dalla normale stampa a quattro colori. Tuttavia, nella stampa effettiva, potresti aver riscontrato problemi simili, ovvero c'è ancora una grande differenza di colore dopo che il colore spot fatto da sé o il colore spot ordinato sono stati inseriti nella macchina e deve essere regolato ripetutamente online per soddisfare il requisiti standard di differenza di colore, che porta La quantità di tempo dedicato alla modulazione delle tinte piatte non è da sottovalutare. Pertanto, come modulare in modo rapido e accurato le tinte piatte sarà un argomento importante e significativo per la stampa delle tinte piatte. L'importanza e il ruolo della densità nella stampa a colori spot Come tutti sappiamo, quando si producono tinte piatte o si ordinano tinte piatte, di solito sottolineiamo la necessità di fornire ai produttori di inchiostri campioni di colore dei clienti, dati sugli standard colore o numeri di colore Pantone e substrati (carta) coerenti con la produzione di massa. Tuttavia, anche se la tinta piatta viene realizzata o ordinata in base a questo requisito, si riscontrerà comunque una grande differenza di colore dopo che la stampa è stata eseguita sulla macchina Corrugated Box Machine. Questo porta a una riflessione: ovviamente, quando la tinta piatta viene preregolata e sviluppata o ordinata, la differenza di colore è in linea con i requisiti standard, perché c'è una tale incertezza quando viene effettivamente stampata sulla macchina? In effetti, abbiamo trascurato un importante elemento intermedio: la densità. Si può affermare che la densità è un "ponte e chiave segreti" nel processo dall'autoproduzione di tinte piatte alla stampa in macchina. Con questo "tasto e ponte segreti" , il colore spot fatto da sé può essere L'incertezza della

¿Cómo garantizar la calidad de impresión de los rodillos anilox de impresión?

¿Cómo garantizar la calidad de impresión de los rodillos anilox de impresión? 1. Preste atención al correcto control de la presión de los rodillos. Mantener una presión de rodadura uniforme y moderada es una garantía fiable para evitar daños en la superficie del rodillo anilox. Sin embargo, si el suministro de tinta no es normal debido a la falta de coincidencia entre la línea de trama del rodillo anilox y la estructura del diseño de impresión, el desgaste del rodillo anilox puede verse agravado por la aplicación incorrecta de la presión del rodillo. Por lo tanto, es necesario ajustar cuidadosamente la presión entre el rodillo anilox y el rodillo de la placa de impresión.Si la presión de contacto entre ellos es demasiado fuerte, es fácil dañar la capa de cerámica en la superficie del rodillo anilox, causando que el borde de la celda se agriete y forme una serie de rasguños Marcas de lesiones. Para evitar este fenómeno, durante la producción, para corregir la presión entre el rodillo anilox y el rodillo portaplanchas, se pueden insertar calibres de tapón del grosor apropiado entre los rodillos anilox y el rodillo portaplanchas en ambos lados respectivamente. Resistencia como el grado, de modo que la presión entre el rodillo anilox y el rodillo de la placa de impresión debe ajustarse a un estado paralelo y la presión de contacto debe mantenerse uniforme. 2. Preste atención al ajuste correcto del raspador. El raspador es una parte vulnerable.Después de un cierto período de uso, el raspador inevitablemente se desgastará, lo que hará que la superficie de trabajo sea irregular, de modo que la parte longitudinal del rodillo anilox se raspe fácilmente en las ranuras. Además, si el dispositivo rascador está suelto y vibra, es fácil agravar el grado de desgaste del mismo y del rodillo anilox. Por lo tanto, el raspador desgastado debe procesarse y rectificarse a tiempo. Si el rascador presenta algún fenóm

Una visita obligada para la gestión de la producción de impresión: causas y explicaciones detalladas de la aberración cromática offset

Debido a que los empaques y productos impresos en offset tienen buenos patrones, textura fuerte y colores intensos, la mayoría de los empaques y productos impresos actuales todavía se imprimen mediante impresión offset. El moderno equipo de impresión offset tiene una alta eficiencia de moldeado multicolor y es el favorito de los clientes. Sin embargo, la impresión offset también tiene un talón de Aquiles: es propensa a la aberración cromática en comparación con otros métodos de impresión. Tiene altos requisitos técnicos para los operadores de impresión offset, especialmente el control del balance de tinta, etc., enfatiza especialmente las operaciones de datos estandarizados. La aberración cromática se ha convertido en el problema de calidad más común y problemático en la impresión offset corrugated slitter. Los clientes se quejan de muchos productos impresos de embalaje offset y se desechan debido a la existencia de diferencias de color, lo que genera muchas pérdidas para la fábrica de impresión en términos de reputación y economía. Como impresores de empaques, debemos prestar atención a la aberración cromática en la impresión offset, analizar cuidadosamente las causas de la aberración cromática y tomar medidas efectivas para superarla Flexo Printing Exposure Machine. A. Blancura del papel: Los papeles con diferente blancura tienen diferentes efectos sobre el color de la capa de tinta impresa. Especialmente para tintas de colores claros con una luminosidad superior a 70, el efecto es particularmente evidente. Esto se debe a que la diferencia de blancura es igual a la adición de diferentes grados de negro o gris a la tinta, por lo que, aunque la cantidad de tinta y el tono no cambian durante la impresión, el efecto de color real se debe a la diferencia de blancur
