Monomaterials close the sustainability chain in the packaging industry

Spain.- The packaging sector is interested in adopting the use monomaterials in their productions in order to achieve multiple benefits. Using these materials can reduce production costs and energy consumption, while reducing packaging waste.

The main advantage this material offers is its high recyclability, since it does not consist of different elements, it eliminates complex classification processes and facilitates its recycling. recyclingwhich in turn contributes to the circular economy and the reduction of the carbon footprint of the company that uses them in terms of production.

Barcelona Packaging Hub, a network of companies founded in 2019, has set as its main goal the provision of effective solutions for the needs of the market through monomaterial developmentin line with its commitment to the environment and sustainable production.

Process monomaterials correctly

INVPack, one of the players in the packaging sectorhe indicated that among the main materials used in the industry are among others paper, polypropylene, polylactic acid and bio-based polyethylene.

These materials are used in flexible forms such as films, which contain multilayer structures with polyethylene and polypropylene, with structures known mainly as Mono PE and Mono PP.

It is important to distinguish dry products from rigid packaging, such as water or drink bottles. The former are made from paper-based materials that include a very thin sealing layer, known as solid paper, while the latter are made mainly from PET (polyester)” labeled INVPack.

However, the implementation of monomaterials in the packaging industry is not simple, since companies must adapt to the characteristics of this material. technology of new materials. One of the key aspects is the sealing temperature, as these materials are less stable when exposed to heat.

Additionally, when monomaterials interact with external elements such as plugs, the sealing process becomes more demanding due to temperature differences between the material and the plug. The protective properties must also be improved in order to adequately protect the products.

The packaging industry faces the challenge of achieving the same protection offered by multilayer materials.

Progress in production

The packaging industry faces the challenge of achieving the same protection offered by multilayer materials, which is what the market demands and expects from the industry. Because of this, major developments in the sector are expected in 2023.

Furthermore, according to a regulatory order, starting in 2030, all packaging used in Spain must be able to be recycled or reused. Synchropack, founder of the company Barcelona Packaging Hub and specialist in new generation automated solutions for packaging, indicates that the trends in the flexible packaging sector for this year will be marked by new monomaterials and their development.

Film producers are increasingly focusing on sustainability and circular economywhich will stimulate the research of monomaterials, monoplastics and flexible paper.
