MeetingPack in Valencia
Sustainability Trends in Barrier Packaging
On 29 and 30 May, the MeetingPack, which took place in Valencia, Spain, has brought together more than 350 professionals under the slogan ‘Sustainability trends in barrier packaging: towards Objective H2030’. Organized by Aimplas and Ainia, the event introduced new sustainable solutions for food and beverage plastic packaging.
For example, Danone showed its latest developments in packaging sector. One of them was Lanjarón 1.25 litres bottle that is 100% rPET and 100% recyclable, the packaging with the largest quantity of recycled plastic of the brand. The multinational has thus made a step forward in its commitment to sustainability. In 2016, their commitment was focused on using 15% of recycled plastic in this entire range. Thanks to this bottle, it has made significant progress in recycling solutions and the recycling of the plastic material used.
Fresh and Frozen Food in One Box
Knauf Industries talked about its latest developments in expanded polystyrene (EPS) and expanded polypropylene (EPP). They introduced two sustainable alternatives that are gaining ground in the food-contact plastic packaging value chain due to their high performance and recyclability. In this respect, new solutions like compartment systems with EPP modular partitions that make possible to have two different temperatures in one packaging. Thus, one box can contain fresh food (at 2 ºC) and frozen food (a -18 ºC) at the same time. Thanks to this, cold packaging can be easily distributed optimizing both economic and environmental costs and making distribution more flexible. In addition Enplater Group introduced its developments in more eco-friendly films, sheets and trays.
Combination of Care of the Environment and Aesthetics
Comexi discussed the challenge of sustainability through the developments of products that combine taking care of the environment and aesthetics. They exhibited packages with visual effects such as transparent windows and paper touch effects as a sustainable alternative to attract consumers.
Better Plastic Bags
Cadel Deinking talked about the use of recycled material as a replacement for virgin resins and presented their bags for automatic packaging, which are 50% made of deinked recycled plastic. In this way, the company offers an added value to post-consumer materials.
Recyclable and Robust Packages
Furthermore, SPGroup talked about PE HB ECO packages made of recyclable material with a polyethylene-based structure and high barrier properties. They are remarkable due to their capacity to withstand thermal treatments such as pasteurization, hot filling and microwaves. It is also characterized by their high transparency. All these solutions are very interesting for a large number of foodstuffs.
Klöckner Pentaplast introduced, among other developments, an rPET recyclable tray made of at least 95% of recycled material, which reduces the carbon footprint and obtains, with minimum weight, maximum resistance.
First Oxygen-barrier PVOH Coating
Artibal presented the first oxygen-barrier PVOH coating to be applied in the printing and lamination process of flexible structures, which has been developed within the Coat4Pack project in conjunction with ITC and Plásticos Romero. These new packages replace co-extruded EVOH structures with more sustainable ones. In particular, it has been achieved to reduce both the manufacturing process and the thickness of the multilayer barrier structure. Oxygen barrier coatings are developed for printing technologies that allow the lightening of the structures of food packages in comparison with the multilayer EVOH structures.
Alternatives to Aluminium-based Structures
Aimplas and Ainia introduced two projects in which they are participating: the Niasafe project, focused on analyzing, monitoring and minimizing the migration of Non-Intentionally Added Substances (Nias) to food-contact packaging and the Refucoat project, which is focused on developing new materials to package food in a more sustainable way. Within this project, barrier coatings are being developed, as well as bioplastics to be used in films and trays as an alternative to the current aluminium-based structures. (bf)
