Packaging Packaging must offer good product protection, but also be attractive. The spectrum ranges from aluminum to corrugated cardboard.The individual companies in the packaging industry produce packaging materials from a wide variety of materials, such as glass, cardboard, plastic or metal. The packaging is tailored to the characteristics of the products and/or is intended to appeal to specific target groups. Aluminum for medicines
The Alcan Group is one of the world's largest players in the aluminum sector. Its two plants in Kreuzlingen and Singen (Germany) specialize in the production of pharmaceutical and food packaging made of aluminum.
According to Dr. Erwin Pasbrig, Director Research & Development for the Pharmaceutical Packaging Division at Alcan Pharma Europe, important trends are emerging in products that are influencing development. In addition to aspects relating to safety and counterfeit protection for medicines, these also include new dosage forms. These requirements need packaging specifically tailored to these needs. "Transdermal patches are on the rise. In these patches, the active ingredient is usually dissolved in gelatin and delivered into the body through the skin. Powder that is inhaled is also one of the newer dosage forms," Pasbrig explains. In both cases, the packaging must have the highest barrier properties against moisture and oxygen. For example, the packaging protects the patches from moisture loss so that the effectiveness of the drug is maintained. In the case of powder, on the other hand, protection against moisture from the outside is important so that it does not clump and can penetrate into the fine ramifications of the lungs when inhaled.
Glass visualizes high quality Vetropack is the only company in Switzerland that produces packaging glass. The company produces mainly wine and beer bottles at its main plant in St-Prex, which is to be renovated next year at a cost of over 30 million Swiss francs. In addition, the company has production facilities in Austria, the Czech Republic, Slovakia and Croatia.
According to Jürg Mossdorf, Head of Marketing and Sales at Vetropack, glass is often used where a good presentation of the products is important: "Bottlers of premium fruit juices and high-quality mineral waters, for example, like to use glass bottles to highlight the quality of their products." Areas where glass beverage bottles dominate are wine and spirits. And according to Mossdorf, glass bottles are also still very popular with beer drinkers.
Wide-mouth jars with screw caps are used for various products - for example, for food that is filled hot or that is pasteurized, or for instant coffee. Baby food is also mostly offered in jars. One of the reasons for this is that the food in them can be sterilized without any problems and presents itself appetizingly at the point of sale. Another practical advantage is that the baby food can be heated in a water bath and the jar also serves as an eating utensil.
PET is light and trendyIn 1985, the company Femit AG (now Resilux Schweiz AG, Bilten) launched the first PET (polyethylene terephthalate) beverage bottle on the Swiss market. Since then, the lightweight, unbreakable, and mostly transparent plastic bottles have conquered the field of carbonated soft drinks in particular: Most soft drinks and mineral water are now offered in PET here in Switzerland.
Eduard Suter, sales manager at Resilux Switzerland, attributes the PET bottle boom to development advances in the material's properties and design possibilities. "We launched the first PET beverage bottle on the Swiss market 20 years ago. In the meantime, there are already young adults who have grown up with it and for whom these containers are a matter of course. We believe that PET bottles and their new and further developments will continue to be successful in the future thanks to this acceptance."
Films - thinner and more brilliantEven lower material consumption, high quality and even more brilliant printing results are expected from packaging and bags made of plastic film. Since these demands have been in place for years, manufacturers and converters have now moved into areas that were unthinkable not long ago.
PetroplastVinora AG in Andwil is one of the leading processors and suppliers of film packaging and carrier bags. Stephan Walti, Co-CEO of the company: "In order to be able to meet the demands of our customers, it is necessary to invest in state-of-the-art processing machinery in addition to continuous research and development. With the new type of extruders that we have put into operation this year, we can produce particularly thin and high-quality films as well as up to seven-layer barrier films for increased requirements in the food and medical sectors."
PetroplastVinora has also invested in printing technology: In the spring, a state-of-the-art ten-color printing press will be installed in Andwil, the first of its kind in Europe for the time being.
Cardboard is still attractiveCardboard packaging is one of the classics in the packaging sector. They not only offer good product protection, but can also be attractively designed and are particularly ecological. It is therefore not surprising that paper, cardboard and corrugated cardboard are the top packaging materials, accounting for around 40 percent of the total.
In Switzerland, cartonboard is produced by Karton Deisswil, a company belonging to the Mayr-Melnhof Group. Its specialties include a ball-bearing carton that is constructed in such a way that grease can penetrate the surface of the reverse side but not the printed carton front. The development makes it clear that even today, cartonboard still offers innovation potential that can be used to expand the circle of users. Due to its stability and high protective effect, corrugated board has made a splash, especially as transport packaging. Developed in the USA in 1871 by Albert L. Jones, the brown packaging material has also conquered retail shelves in recent years thanks to its modern and colorful design. The various corrugated structures - visible as an "open corrugation" - as well as printing and finishing techniques are used as design elements. In addition, corrugated board is used for the production of displays because of its high stability. Innovations in printing technology - especially improvements in flexographic printing - have contributed to the fact that corrugated board is now also used as presentation and sales packaging for premium products.
According to Hansulrich Brauchli, Managing Director of Langenbach AG, which is part of the Lande-Langenbach Group, the trend towards increasingly sophisticated packaging continues unabated. For example, corrugated board that has already been printed to a high standard is additionally enhanced with foil embossing, relief embossing, matte and high-gloss coatings. MFX inks also offer interesting possibilities in offset printing, because they can be used to achieve beautiful metallic gradients, for example. However, it is important that printers and prepress operations are involved in the design at an early stage. Another trend concerns logistics packaging, where corrugated board has always been strongly represented. "They are increasingly taking on the function of display packaging," notes Brauchli. This is particularly true in the German market. For example, at the large discounters, products are presented in their outer packaging at the point of sale. Particular attention is therefore paid to the design of the control cartons. Often, these are even provided with an inside print.
Special case labelsWithin the various packaging materials, self-adhesive labels occupy a special position. On the one hand, they can be applied directly to the product, on the other hand to the packaging, thus communicating product and manufacturer information. Due to the low material requirements, the wide range of design options and the high functionality, labels offer a good cost-benefit ratio. They can be applied to plastic containers and cardboard boxes as well as to tubes, metal cans and glass bottles.
The market for self-adhesive labels has grown continuously in recent years. Especially in the beverage sector - formerly the classic area for wet glue labels - self-adhesive labels are increasingly used today. Swiss companies specializing in the manufacture of self-adhesive labels and labeling technology (e.g. Pago AG or Tesa Bandfix AG) have repeatedly developed new products in the decorative, promotional and functional sectors in recent years. Self-adhesive labels with glossy and tactile special effects, for example, are now available. Velvety soft or iridescent label surfaces are also in vogue. Multi-page labels are also an alternative to package inserts and can also be dispensed or used as promotional tools (e.g. for contests, recipes and collectible pictures).
In the field of promotions, self-adhesive labels are finding ever new uses. Among other things, this also applies to the interaction with new media, e.g. in competitions. Emanuel Schäpper, Head of Sales and Field Service at Pago AG, mentions the extra-long self-adhesive label developed by Pago under the name Pagomedia XL, which can be printed with information on the front and back and used to integrate a coding field. By means of SMS, the code can be sent to a target number. The sender receives feedback within three seconds as to whether he or she is one of the winners. Pago has also recently invested heavily in sleeve and wrap-around labels. This relates to machine technology and printing technology. Schäpper also sees potential for RFID labels (see article on page 23), particularly for logistics applications: "We have also invested in this area, so that we can now produce RFID labels ourselves in any size".
Glass is especially popular when the product is well presented
should be.
Logistics packaging is increasingly taking on the function of displays.
In the cosmetics sector, folding cartons are a must. Sophisticated subjects in high print quality are the rule here.
The particularly lightweight PET bottles were introduced in Switzerland 20 years ago.
These highly transparent tube labels from Tesa Bandfix are virtually invisible and fit like a second skin.
So-called bottle tags are ideal advertising media.
