Volatile demand for film production lines is the shifting ground on which the Brückner Group has been operating successfully for years. It repeatedly opens up new markets through acquisitions. Standard systems for packaging are required to achieve greater productivity. In "specialties," development of the technology is driven by trends such as separator films for batteries.

There is little doubt where we are heading: multilayer packaging will have to become easier to recycle – but what does that mean for the technology? And what solutions will the market need and accept? Manufacturers of branded goods are not the only ones who will have to rethink their specifications.

Europe Needs to Catch up

Even more than with foodstuffs, what matters in most cases with drug packaging is the contents protected by the wrapping. These are not good conditions to pursue a cycle concept for packaging. But times are changing – perhaps.

Steps to More Sustainable Packaging in the Medical and Cosmetics Industries

No Chance for the Cycle Concept?

The challenges associated with recycling food packaging are particularly great in the flexible-packaging sector. Multilayer composites are often a hindrance to mechanical recycling, yet are irreplaceable in many applications. Replacements will not be found until recyclable and ecologically sustainable packaging solutions are devised.

Looking forward to Interpack 2023

Plastic packaging has a very bad reputation. Despite this, they are almost without alternative in food production

Plastic packaging has a very bad reputation. Despite this, they are almost without alternative in food production – especially when they close material cycles. This is also demonstrated by the exhibitors at Interpack 2023.

Food packaging today is so much more than just protecting the individual product. It is true that the most important function, from the moment of packaging throughout transport, storage and retail, is to ensure that the contents arrive in private households in one piece. But design and material also have a large influence on buying decisions, because more and more people want food that comes in a more sustainable packaging.

Without any packaging, however, most foods cannot be transported, stored or sold, and in their unpackaged state they would prematurely spoil. The protective wrapping keeps harmful influences like light, oxygen or humidity away and prevents soiling or damages. An extended shelf-life is a meaningful contribution to reducing food waste.

Along the entire value creation chain, globally more than 930 billion t of food are thrown away every year. This figure comes from the last report by the United Nations Environment Programme (UNEP). The Swiss society Food Waste even goes so far as to say that on average, a third of all food is lost or goes to waste on the way from the field to the plate. It is therefore part of the UN Agenda 2030 to cut the worldwide waste of food per capita in half until 2030. The authors of the Food Waste Index Report 2021 also assume that eight to ten percent of global greenhouse gas emissions stem from food which is not consumed. Packaging can help to curb this wastefulness.

But packaging is not only there to extend freshness and shelf-life. Consumers are increasingly demanding environmentally friendly packaging. It is supposed to be recyclable or made from sustainable materials, yet offer optimal protection for perishable products. And this means that especially food packaging today is a real high-tech product.

For example, the company Allvac Folien GmbH has developed an eleven-layer polyamide/polythethylene food wrap which is fully recyclable and for this has been awarded certification valid throughout the EU by the cyclos-HTP institute. “Offering no eco-friendly packaging solutions is no longer an option. The pressure on food manufacturers simply is too great.” says Dr. Andreas S. Gasse, CEO of allvac Folien GmbH.

For aroma-proof food packaging, suitable materials are polyamide films with so-called bi-axial orientation, used for example to package oily, fatty foods or frozen foods. The demand for these films, which owe their special properties to a certain stretching process, continues to rise and so does the demand for relevant film stretching lines. One manufacturer of such lines, Interpack exhibitor Brückner Maschinenbau, also focuses on greater efficiency while producing the films. From a mechanical engineering perspective, this is achieved through less use of resources, less consumption of energy and a “zero waste” policy in film manufacture.

Greiner Packaging already uses packaging solutions made of up to 100 percent PET recyclates, so-called rPET, and wants to demonstrate that this is what the food packaging of the future could look like. With the help of the heat-resistant material rPET HTS, in the future, recycled PET is said to be usable even for products that require sterilization through heat.

The packaging manufacturer has also developed a self-separating cardboard-plastic-combination which is supposed to make recycling easier. This is achieved by the cardboard wrap, which stabilizes a plastic cup manufactured with thin walls, already separating from this cup by itself during the waste collection process. Cardboard and plastic can thus already be sorted into the correct flow of material during the first separation process, meaning before the packaging even reaches the recycling plant.

PET recycling is a long-established process and provides recyclates for new food packaging. But other plastics, too, can be reused to manufacture packaging for food. With the chemically recycled polyamide Ultramid Ccycled, for example, BASF offers new possibilities for the development of sustainable packaging especially for the fresh goods sector.

The chemical group is exploring new opportunities to use plastic waste in its “ChemCycling” project and is further developing pyrolysis technology which is used to gain new resources from plastic waste which would otherwise be energetically recycled y or sent to a landfill. “A thermochemical process lets our partners gain recycled raw materials from old plastics, which are then fed into the BASF system. By looking at the mass balance, the raw material can be tracked to certain products, for example Ultramid Ccycled. This helps to replace fossil resources and is an important step towards a circular economy. As chemically recycled plastics are equal to new products with regard to their quality and safety, the range of sustainable plastics which can be used to package fresh goods is increasing”, says Dr. Dominik Winter, Vice President of the European polyamide business at BASF.

Marking Compostable Film without Printing

In order to provide optimum solutions to companies for coding and marking their food packaging, at the Domino Laser Academy in Hamburg, experts from the company are researching and experimenting with new substrates. “We spend a lot of time analysing new packaging materials. Due to the new European legal requirements for recycled plastics, around 95 percent of the food packaging samples we need to test are recycled or recyclable plastics. Our fibre and uv lasers offer many good solutions for coding these substrates. We are however convinced that in the coming years, the demand for compostable solutions will increase. We therefore want to be prepared to offer our customers relevant advice and solutions for these new materials”, says Dr. Stefan Stadler, team leader at the Domino Laser Academy.

According to this focus, the laser team has tested the compostable NatureFlex film products by the Japanese company Futamura regarding their suitability for laser coding. The laser produces a crisp, white code on the film without damaging the integrity of the original film, changing the chemical composition, or affecting the properties of the moisture barrier. The print-free coding method does not require additional materials on top of the compostable substrate, which should make gaining certification for the final packaging much easier.
