Compostable biopolymer PBS replacing fossil plastics
14/11/2023
Bioplastics can replace conventional fossil plastics in many applications while being processed in the same way. One important type of bioplastic is PBS. The biopolymer is plant-based, biodegradable and recyclable. A Japanese tea manufacturer is now using PBS in the packaging for its tea bags.

Less material and more green energy: The glass industry is becoming more sustainable
17/10/2023
Glass is the ideal packaging material for beverages and foods. It is odourless and neutral in taste and does not react with the filled goods. However, its production is very energy intensive and the industry is working hard to become climate-neutral.

New bottle design – 100 percent fibre-based
11/10/2023
The interest in fibre bottles is large, as they are lightweight, robust and made from renewable resources. The material does not always have to be wood from fir and deciduous trees, left-over material from food production is also suitable. For example sugar beet chips, which are a waste product of sugar production.

How labels are becoming more recyclable
12/09/2023
A world without labels? Inconceivable. Their endless variety of materials, shapes and functions help labels attract attention. But it should also be possible to separate them from their packaging again at the end of the packaging’s life in the interests of a circular economy. Recyclable solutions are on the way.

Sustainable print finishing
12/09/2023
Embossing, colour effects and particularly metallic sheens catch the eyes at points of sale. Finishing labels and folded boxes with conventional embossing foil, however, creates lots of film waste. But now an alternative, which allows metallic pigments to be applied selectively and cost-effectively and which consequently eliminates the need for plastic film, has arrived.

Paper lids for less single-use plastic
15/08/2023
When the time comes for a hot or cold drink while out and about, many people opt for takeaway beverages in disposable cups. These often come with a plastic lid, resulting in a significant volume of waste. One Finnish start-up is instead using recyclable paperboard lids and has entered into a partnership with Walki.

Eurostars project for fibre-based packaging concluded
11/07/2023
As part of the Eurostars funding programme, PulPac in Sweden and the Bio-Lutions start-up in Germany have together developed a prototype for a new dry-moulded-fibre machine that’s able to process fibres from agricultural waste. The project saw them adapting standard components that are traditionally used to make plastic products.

Tin packaging becomes more climate-friendly
13/06/2023
They are regarded as best for recycling: Tin cans, tubes and bottles. But they don’t score well in terms of their carbon footprint because it is not yet possible to produce steel without using coal as the source of energy. Industry is, however, working on more sustainable solutions and has launched the first carbon-reduced steel for packaging.

Considering the carbon footprint during refitting
13/06/2023
Packaging materials are usually the first thing that come to mind when the topic of the ‘carbon footprint of packaging’ is brought up. Machines, however, also produce emissions. But even relatively simple modifications may result in considerable savings. A tool by the KHS mechanical engineering company in Germany is able to quantify those savings.

Compostable coating for food-safe paper packaging
13/06/2023
Barrier properties are particularly important to food packaging. Consumers are additionally demanding solutions that are environmentally friendly. BASF has developed an extrusion coating for paper and cardboard packaging, which may be composted both industrially and domestically.

What are the benefits of paper tubes?
16/05/2023
Packaging is being viewed differently in these times of ever scarcer raw materials and increasing environmental issues. As are tubes. Some companies are placing their hopes on fibre-based solutions, e.g. paper. But are there only benefits to paper tubes?

SAVE FOOD research project: New food packaging from leftover food
18/04/2023
Food production generates a lot of residual material, which is usually not put to use but disposed of. At the same time, there is an increasing demand for alternatives to plastic packaging. Biodegradable and compostable packaging can be a sustainable solution, especially if it is made of leftovers from food production.

Bioplastics in packaging
14/02/2023
There is a reason why the packaging industry has been focusing for decades on the many different applications for fossil plastics. Now, companies are increasingly focussing on biobased plastics. But what are the possible applications, and what needs to be considered during the changeover?

Thinner sleeves for more sustainability
14/02/2023
Everyone is talking about sustainability. The way to an improved carbon footprint is to decrease the use of unnecessary material. Austrian company CCL Label, for example, were recently able to decrease the thickness of their stretch sleeves for PET bottles by one third.

A bioplastic for every application
24/10/2022
Fossil plastics have a lot of advantages, but they are also said to be harmful to the environment. Bioplastics are an alternative for packaging manufacturers. They are just as versatile, but are made using renewable resources, and some are even compostable.

Use of recyclates in packaging
24/10/2022
If there is one thing the industry agrees on, it is that more recycled raw materials must be used. In the case of plastics, this means recyclates. They are in greater demand than ever, but the supply is still relatively small. What do packaging manufacturers have to pay attention to when using them, and what has to change so that more recyclates can be used?

A closure fighting food waste
24/10/2022
Too much food is still being thrown away around the world, even though it may still have a shelf life. Together with United Caps, a London start-up has now developed a bottle cap that provides information about the edibility of the contents beyond the best-before date.

Reliably determining the carbon footprint of packaging machines
26/09/2022
Companies are looking for ways to make their production and their products more sustainable. One of the important factors is the machinery which is used here. TÜV Rheinland has now certified a method by Syntegon which determines the carbon footprint of the machines produced by the company.

Life cycle assessments – a useful tool or greenwashing?
26/09/2022
Plastic or paper, single use or reusable – which packaging gets the best marks in a life cycle assessment? The answer often appears to be simple, but an environmental assessment should always look at the individual case in detail, because there are benefits and drawbacks everywhere – and the results are sometimes surprising.

Sausage wrap that can be recycled
21/07/2022
Sliced sausage is supposed to look good on the refrigerator shelves in the supermarket and is usually wrapped in non-recyclable transparent composite film. Now, thanks to energy-efficient heating systems in thermoforming machines for packaging, it is possible to use more sustainable materials – while maintaining the same level of safety, quality and transparency.

Less material needed to produce sealing films
21/07/2022
Films are an important part of packaging: They provide an impenetrable barrier between the product and the environment. That said, industrial handling of such sealing films is not always simple. A cooperation between Plasthill and Constantia Flexibles has now led to the development of a PE film which uses less material, thus leading to reduced CO2 emissions, yet has greater seal strength.

Hemp, a trending material?
24/06/2022
When cannabis is mentioned, its intoxicating effects are the first thing that springs to mind for most people. However, the European hemp varieties that are cultivated today contain very little that is intoxicating, and instead have a high amount of fibres that are ideally suited for making them into paper labels, cold storage packaging or even one-way pallets.

Mono-material sachets
21/06/2022
For packaging made of plastic, their potential to be recycled is very important. Refilling systems save material. Mono-material sachets and bags also reduce the amount of material consumed, protect packaged goods and have practical uses for customers.

Flow packs as a sustainable solution in food packaging
25/05/2022
From requiring less material in production to taking up less space on supermarket shelves, flow packs have some clear benefits. Predominantly used in the food sector, this packaging is becoming more and more popular. But how sustainable are these packs?
