Russian e-commerce market targeted by Mondi


easily reseal and return items has been developed by Mondi. Re(use) is a one-piece shipping


A


package featuring a double hot-melt application. The first hot-melt strip is used during fulfilment to tightly seal the package for dispatch, making additional plastic foil wrapping or bagging obsolete. The convenient tear-open strip – located between the two hot-melt strips – gives consumers easy access to their products upon receipt. If the product is not to their liking, the consumer can use the second hot-melt strip to quickly reseal the packaging and return it.

director of Mondi Lebedyan commented: “This smart, yet simple, solution meets the growing demand of Russian customers for user-friendly packaging. Our easy-to-use, light and sustainable packaging solution helps brands stay competitive on the e-commerce market and boost brand loyalty.” The packaging solution for


Re(use) was first launched at


the RosUpack show in Russia, where the e-commerce market is


expected to reach almost US$22 billion by 2020. Mariusz Sobieraj, managing


e-commerce was developed for the German and Polish e-commerce market for clothing, shoes and accessories. To accommodate similar requests in the near future, Mondi’s site in Lebedyan, Russia, was recently equipped with a brand-new folder gluer, and is soon to be expanded by a hotmelt and tear tape unit.


Next generation rheology meter for coatings


A ‘next generation’ rheology meter for evaluating the viscosity of coatings used on paper and board packaging has been launched by ACA Systems. The AX100 is said to be capable of measuring the viscosity simultaneously from low to the ultra-high shear region. Coatings or water-based barrier dispersions are rheologically complex materials, and their viscosity is highly dependent on shear rate. Modern high-speed coaters generate shear rates of more than 1,000,000 1/s, during which the hydrodynamic forces are dominant and the viscosity in that region is a reliable indicator of coating runnability.


Until now, low-shear rheograms


have been commonly used in the industry to assess the runnability of coatings, yet there are several experiments that demonstrate that due to lack of hydrodynamics, the low shear viscosity results can be extremely misleading when it comes to the prediction of coating performance on high speed metered size press, rod, blade and curtain coaters. This has created a need for instrumentation that is more specialised in ultra-high shear region to better understand the rheological properties under true coating conditions. Being able to introduce the real conditions into a lab instrument reduces


significantly the development costs and time to market as trial and error mill scale trials can be avoided. The AX100 is a stand-alone


system consisting of an automatic movable cylinder that is released at pressure of 100 bar. Samples (50-350 ml) contained in the cylinder are forced through a small capillary and depending on the flow rate the viscosity can be calculated as a function of shear rate. Results are shown in graphical curves or single numbers describing selected shear rate area. For data analyzing the AX100 is equipped with USB and wireless capabilities to quickly transfer data into a cloud services or mill


wide systems. ACA’s chief executive Vesa


Kukkamo says: “The new uses- friendly analyzer makes the coating development and quality control easier than ever. Due to ultra-high shear rates provided by the analyzer, the rheology of the coating colour can be studied in the real process conditions, having a very good correlation to actual coating runnability. This is extremely important for example in sustainable water based barrier coatings that are typically very challenging in terms of runnability.” More information from ACA
