Makingit innovative

Royalpack is the one and only company in Europe that has a unique solid board production line with various innovative technological solution, which is able to laminate the product at once.

New generation large-format printing machines produce excellent high-resolution offset or flexo print on the substrates that we use. Other processing equipment, such as automatic die cutters for corrugated cardboard and solid board are able to produce even the most complex structures with high precision. Last but not least, there are our advanced folding and gluing lines which close the packaging block by the means of hot melt glue, low melt glue, pressure sensitive adhesives, staples or specialistic adhesive tapes. Ultimately, the packaging offered by Royalpack becomes an effective marketing tool for the customers who have trusted us, which we also are proud of.

Offset printing

Offset printing is the perfect solution for the most demanding graphic projects. It not only provides high quality of the overprint, but above all, it gives the best possibilities when it comes to refining. Royalpack is equipped with a new generation large-format offset printing machine, thanks to which it can produce the following finishing:

Standard, with CMYK ink, Pantone and dispersion varnish
Food ink
Fluorescent ink
Metallic ink
Print on PE+PET layer
Food varnish
Soft-touch varnish
Anti-slip varnish
UV varnish
Selective varnishes, e.g. matte primer + UV
Primer varnishes for foil lamination, e.g. metallic

We have introduced the unique packaging series called NATURA LINE, in offset printing. It is designed for precise printing of uncoated brown paper, as well as grass paper and thus offering our customers the chance to choose sustainable products. We believe that offset printing does not have to be associated exclusively with coated bleached paper. We are proud to present pro-ecological solutions along with the most unique packaging solutions allowing products to be effectively advertised in stores.

Flexographic Printing

Flexographic print has earned its place among printing methods recently. Undoubtedly, thanks to the ongoing work of R&D teams of large-format printing machine makers, the quality of this type of printing has reached high level. Its major advantage is the ability to print directly on the cardboard’s sheet, which allows for.

Grammage reduction of particular layers of corrugated cardboard
Shortening the order fulfilment time by eliminating the laminating process
Packaging cost optimization

Thanks to the hi-tech large-format flexographic machine and the fact that we produce cardboard by ourselves, we have real and full influence on the quality of the offered packaging.

Royalpack understands that machines are not everything. The people who you work with are the most important. Our printing staff are masters of their profession. Thanks to them and to cooperation with well-known material suppliers of paper, ink and photopolymers (plates), we are able to carry out the most demanding projects.

Barriers

We aim at sustainable growth. Our goal is to limit the use of synthetic materials in the production of packaging while adjusting the processes to meet ecological standards at the same time. How to secure a product against moisture, grease and savour? The answer is simple: barrier solutions - biodegradable and food-grade.

Transparent PET foil is used for securing the cardboard’s surface (e.g. protecting the content of the packaging from the inside so that it does not go outside). This method is similar to laminating with BOPP foil, except for the fact that PET foil has high surface tension and can be glued by a folding – gluing machine.

Our waterproof and grease-resistant barriers are used in various areas.

For fast food products such as hamburgers or pizza.
For dishes that require heating up, e.g. in a microwave oven.
For products being prepared in the oven.
For food stored in a freezer.
For hot drinks providing high cup protection.

Our barrier solutions are thermo-active, which allows to glue layers of paper together through temperature and pressure – without using extra hot melt glue. We can adjust the amount of material in order to obtain the perfect barrier and permeability proportions for a particular product. Thanks to the wide barrier customization spectrum, we are able to create packaging perfectly matching the end product. We all work for ecological solutions and a sustainable future together.

Refinements

Packaging is not only defined as a way of protecting the goods, but above all, it creates the product brand. Refinements work best among offset-printed packaging and those made of solid board in particular. We offer the following refinements:

Varnish: dispersion, gloss dispersion, matte, soft touch, ant-slip, structural and other
Ink: standard, metallized, fluorescent and other
Foil: gloss, matte, soft touch, anti-scratch, metallized and other
Selective hot-stamping
Embossing: concave, convex
Window: PET foil used in window box packaging

Quality Control

We consider quality to be most important, which is why our packaging is made of the highest quality raw materials. We constantly supervise the conditions in the production hall and warehouse. The ISO 9001:2015 system, which has been implemented, ensures the coordination of all operations and processes.

Our quality control department does thorough performance tests of our packaging on a daily basis:

WEIGHT

This is the main parameter where the value is the weight of 1 m2 of corrugated cardboard sheet expressed in grams (g/m2). The grammage is an important feature when choosing the proper type of cardboard because the higher the grammage value, the thicker and stiffer the cardboard is.

ECT

It is the index of corrugated cardboard resistance to edge creasing – its force related to the cardboard’s sample edge length, acting parallel to the waves direction and causing the sample’s collapse. This force has key importance when the boxes are stacked. The wave type has basically no influence on ECT. The ECT value is mainly determined by the class of paper used in the production process.

BCT

The compression resistance index of the packaging is shown by the force value acting directly on the packaging when it is being creased causing its deformation or destruction. This parameter is affected by all features of a given package: its dimensions, structure and the type and durability of the cardboard. The BCT value is directly related to ECT.

PRINTING SUBSTRATE’S WHITE BALANCE

The key element of obtaining a high-quality print is testing the substrate’s whiteness. At an early stage of preparing a project, we have to be absolutely sure that a particular printing paper meets the requirements. The substrate’s whiteness plays a crucial role in the use of light (transparent) colours in a graphic project as it directly affects the end print. The measurement is performed with an X-Rite eXact spectrodensitometer. It allows to verify the quality of the used substrate’s and to come up with proper ink formula.

MOISTURE

The index presenting the ratio of the weight of water in the cardboard to the weight of the whole product. It depends on air humidity, as well as on the temperature of the surrounding and the composition of the cardboard. In order to keep the correct features of the cardboard, it is advised to provide the best possible storing conditions. The locations must be dry and airy as their temperature can’t drop below 4°C – the recommended temperature should be stable between 18 and 22°C. The moisture should remain at 60% and it should not go under 45% in heated locations. If the cardboard’s moisture value is too high, it may result in the change of cardboard’s physical properties, such as: stiffness decrease, linear deformation, higher compressibility, thickness or roughness. On the other hand, if the cardboard’s moisture is too low, the waves may crack, and thus the whole sheets.

DELTA E

This is an index measured using an X-Rite spectrodensitometer which shows the printed colour deflection degree from the given pattern. The X-Rite eXact spectrodensitometer is the latest device used for improving the offered packaging quality – all for meeting the needs of customers. X-Rite eXact allows to control and maintain the colour just to obtain the best accuracy of colour measurement. So, if we aim at receiving a particular colour on the printout, the closest we get to it on the target printout, the delta E index value will be closer to 0. When the spectrodensitometer measures 0, it means that we have obtained a colour perfectly matching the pattern. It is claimed that the human eye of most people is unable to notice a difference in a printout with a tolerance of delta < 2.0.
