In order to meet the demand from the market for alternative packaging materials, the two companies Leipa Georg Leinfelder and Koehler Paper Group have developed in conjunction with Multivac a cardboard composite, which can be used for packing fresh food such as meat for example. This innovative solution based on paper fibre packaging material was presented at IFFA on the Multivacstand and run on a compact thermoforming packaging machine. The packs are designed in such a way, that the end user is able to separate the cardboard backing from the plastic barrier layer and then put it into the paper recycling.

Multilayer composite for skin packs

When developing this material, the challenge was to produce a cardboard composite with high barrier properties and a suitable sealing medium, which has the stiffness of a flat pre-cut card sheet but is also capable of being wound onto a roll, so that it can be run on a thermoforming packaging machine. The first results show that the Leipaflat multilayer composite is excellent at meeting all the requirements. This material can be used on a thermoforming packaging machine to produce skin packs, which not only package the product securely but also present it attractively to the consumer. As a strategic development partner in the board sector, Koehler provides Leipa with the material for manufacturing Leipaflat.

“Leipaflat is made of up to 90 percent renewable raw materials. Compared to the conventional packs used for these products, the features of this packaging material are its appearance and feel of a paper pack, and this contributes significantly to product differentiation in the chill cabinet,” explains Matthias Haux, Commercial Head of Flexible Packaging at Leipa. “This solution meets the high aspirations and demands of consumers, who are conscious of both quality and the environment. The cardboard offers not just the required stiffness, but it can also be run particularly well on thermoforming packaging machines thanks to its ease of winding on rolls. This solution can generally also be used on existing machines and dies. If requested, we are always willing to give customers advice on site about the optimum settings for their equipment.”

Danny Köppl, Product Manager for Films & Consumables at Multivac, adds: “This sustainable packaging solution, which was launched at FachPack 2018 and marketed under the Multivac PaperBoard range, has already received a very positive reception from professionals in the trade. Now we are receiving a large number of enquiries from the market, particularly against the background of the EU Plastics Strategy, and these are coming not only from Germany and Western Europe but also from many other regions such as Eastern Europe, North America and Oceania. We are currently carrying out a large number of sample productions for a wide range of customers.”

“We see great potential for this project, which has begun very successfully, and we are convinced that we can address the future of packaging in conjunction with our highly qualified partners, who embody the same collaborative ideas as we do,” says Dr. Markus Wildberger, Corporate Director of Technology at Koehler. “As part of our own ideas on sustainability, this project supports our aims of replacing plastics in packaging with paper-based materials, where it is sensible and practical to do so. This means that a product made from renewable raw materials is used, one for which closed-loop recycling has already been developed. We see in this and other collaborative projects the opportunity to develop and market further innovative solutions in the sector of flexible and rigid board packaging.” Dr. Wildberger also emphasizes that this could involve developments in the non-food as well as food sector.

“Based on today’s knowledge of the planned harmonisation of the EU regulations on plastic disposal, we assume that Leipaflat will lead to significant cost benefits in the context of the packaging fee for companies,” says Matthias Haux from Leipa. “And last but not least, the environment as well as consumers also benefit from this solution.”

PaperBoard

The PaperBoard portfolio comprises a wide range of solutions for producing MAP and vacuum skin packs from paper fibre-based materials. In conjunction with leading manufacturers, the company has developed suitable packaging materials, which can be run on standard machines. By using different functional layers, it is possible to produce packs from paper fibre-based materials, which also meet the barrier requirements of the most sensitive products. The packs can be designed in such a way, that the end user is able to separate the cardboard backing from the plastic barrier layer and then put it into the paper recycling.

Picture: Multivac

At Fachpack 2019 Multivac will be showing a number of forward-looking innovations from its various business units. The exhibits include the new X-line machine generation, which will be presented at the trade fair in the form of the RX 4.0 thermoforming packaging machine and the TX 710 traysealer. Another focus of the trade fair will be concepts for sustainable packaging. These meet the current demands for recyclability and for minimisation of plastic consumption in the production of packs. The company’s presence at the trade fair is rounded off with a presentation of its labelling and marking innovations, including a new generation of cross web labellers and new direct web printers, as well as a solution for efficient wrap-around labelling of packs (full-wrap labelling).

Multivac has expanded its X-line machine generation with the addition of a further future-proofed model, the new TX 710 traysealer. The features of this traysealer are a robust machine concept and an intelligent control system, which together provide the maximum flexibility, output and reliability. In Nuremberg the TX 710 will be the centrepiece of a fully automated packaging line, which also includes a L 310 conveyor belt labeller for the attractive wrap-around labelling of packs (full-wrap labelling).

A second packaging line will have at its heart the RX 4.0 thermoforming packaging machine, which features a range of innovative technology. Thanks to its comprehensive sensor system and seamless digitalisation, it creates a new dimension, when it comes to packaging reliability, quality and performance. At Fachpack the RX 4.0 will be equipped with a new generation of cross web labeller, which gives even greater labelling accuracy at an even higher level of output.

Another of the company’s themes at the trade fair is the presentation of sustainable packaging solutions. On display will be a wide range of concepts, which contribute to reducing packaging material consumption in the production of packs, as well as other concepts for producing packs, which meet current requirements for recyclability. One example of this is the Paper Board range, which is made up of a wide variety of paper fibre-based materials for producing MAP and vacuum skin packs on thermoforming packaging machines and traysealers. This innovative packaging concept will be shown at the trade fair on the compact R 105 MF thermoforming packaging machine, an economic entry-level model for producing vacuum skin packs in small and medium-sized batches. The packs can be designed in such a way, that the end user is able to separate the cardboard backing from the plastic barrier layer and then put it into the paper recycling.

The fully automatic T 300 L traysealer is also a space-saving, entry-level model. The machine can be designed as multi-track and combined with various discharge systems. Thanks to the simple die change, it can quickly be converted for different pack sizes and shapes. All conventional trays from a wide range of materials can be run, as can pre-cut cardboard sheets.

Digital sorters for wet-end vegetable processing

Published

on

Key Technology, a member of the Duravant family of operating companies, presents their most versatile Veryx belt-fed digital sorters, with specific design elements that benefit vegetable processors producing multiple products. Veryx is a belt-fed sorter that can inspect product entirely in-air with top and bottom sensors in order to detect and eliminate all foreign material (FM) and the right amount of product defects to make grade. Featuring Key’s unique recipe-driven operation, along with the ideal hardware and software to sort any number of different products, Veryx can be changed over to handle a new product in seconds. With sort recipes saved to memory for quick recall, Veryx eases use and ensures repeatable results to optimize product quality and maximize yield.

“Worldwide, many vegetable processors typically handle three or more seasonal products throughout the year to fully utilize their factories. In Europe, they might handle as many as 30 seasonal products. In these high changeover environments, processors need more production flexibility. With a multitude of successful Veryx installations, our recipe-driven operation is field proven to help customers achieve consistent sort performance so product quality is guaranteed day in and day out, regardless of personnel changes and across multiple lines and locations,” said Karel Van Velthoven, Advanced Inspection Systems Product Marketing Manager at Key. “Our expertise in vegetable sorting enables us to develop the most effective recipes. With a couple of taps on the touchscreen, an operator can retrieve a recipe saved to memory and accurately set Veryx to handle the next product.”

For processors of both canned and frozen vegetables that are sorting a variety of wet products prior to blanching, Key tailors each belt-fed Veryx with the ideal sensors, sensor positions, lighting, ejection system, product handling and software dedicated to the processor’s products and objectives. Capable of detecting color, size, shape and structural properties of every object, including the presence or absence of chlorophyll, Veryx removes insects, animal parts, paperboard, wood, rocks, plastics, glass and extraneous vegetative matter (EVM) such as weeds and other plant materials, as well as product defects. Veryx comes in different sizes to satisfy a range of production capacity requirements.

The next-generation 4-channel cameras and laser scanners available on Veryx offer twice the resolution of previous sensor technology. Optional Pixel Fusion combines pixel-level input from multiple cameras and laser sensors to produce higher contrasts and enable the most-difficult-to-detect FM and defects to be removed without false rejects. When configured with top- and bottom-mounted sensors, Veryx achieves all-sided surface inspection to maximize FM and defect detection. By positioning bottom-mounted sensors, along with light sources and backgrounds, away from product splatter, Veryx sustains full-surface inspection throughout the longest production cycles in the most demanding environments.

Essential for all processors, especially those handling a variety of different products, Key’s expertise in both sorting and product handling enables them to design the ideal integrated system for each application. Every system is customized to effectively present product to the sorter’s inspection zone, maximizing sort accuracy, with minimal mechanical changes. Application-specific infeeds and collection shakers can serve additional functions, like dewatering and mechanically screening out FM. Optional three-way sorting enables Veryx to optically separate good product into two grades while removing FM and defective product into a reject stream.

As the most advanced sorter on the market for data collection, Veryx can leverage Key’s powerful Information Analytics software, which allows users to analyze and share big data across their enterprise via an Opcua-compliant infrastructure at the same time they sort. Data about the sort process and about each and every object flowing through the sorter, whether the data is used to make sort decisions or not, is available to reveal patterns, trends and associations. This data can help a processor better manage incoming raw materials and optimize processes upstream and downstream of the sorter to achieve the next level in operational efficiency.
