How biodegradable hot melt adhesives can support the corrugated and carton packaging industry

As consumers and brands alike increasingly prioritise eco-conscious products, sustainability is becoming a harder issue for the packaging sector to ignore. Corrugated and carton packaging converters need innovations that can bolster the sustainability of their designs, enhancing recyclability and helping to reduce waste.

Biodegradable hot melt adhesives like Tecbond 214B are one such innovation. Matching the performance of other Tecbond products while being capable of breaking down naturally in the environment without leaving behind harmful waste, Tecbond 214B is the ideal solution for supporting converters in making their packaging more sustainable.

The growing need for more sustainable packaging

Converters looking to bolster their packaging’s eco credentials must first overcome several obstacles:

Resource efficiency: Manufacturing cardboard is resource intensive, using significant amounts of water, energy, and fibres processed from trees. As a result, keeping material in use reduces the need to extract and consume more resources and minimises packaging’s environmental impact. In practical terms this means prioritising reusable packaging where possible, and recycling it at the end of its operational life to keep its resources in the supply chain.

Recycling contamination: Paper and card-based packaging is relatively easy to recycle – in fact, almost 71% of this type of packaging in the UK is recycled. However, contamination from consumables can hinder a pack’s recyclability. Inks, coatings, and adhesives typically need to be removed from a substrate during the recycling process to preserve the quality of the fibres when they are repulped. Failure to remove these substances would damage the integrity of the recycled material, reducing its value for producing more packaging.

Waste: Consumables removed from a substrate during recycling are skimmed off and must be disposed of separately. Typically, this is achieved by incinerating the residue, resulting in unnecessary carbon emissions, or sending it to landfill which can lead to harmful chemicals and microplastics leeching into the environment.

Lack of infrastructure: Insufficient recycling facilities, inadequate collection programmes, and limited transportation networks for collecting and transporting cardboard waste to recycling centres can also pose a barrier to circularity. Ideally, all packaging would be correctly disposed of post-use, but unfortunately, this is not always the case. If the correct local infrastructure is not present for consumer recycling, some packaging may end up being landfilled, where the adhesives used on it will cause harmful chemicals to enter the environment. Limited consumer understanding about correct recycling can also exacerbate this problem.

Biodegradable hot melt adhesives

Biodegradable hot melt adhesives like Tecbond 214B offer a groundbreaking solution for enhancing sustainability in corrugated and cardboard packaging. This innovative adhesive is designed to break down naturally in the environment, leaving behind no harmful residues or microplastics. This process only requires exposure to oxygen, heat, and UV light to begin, with no need for additional treatment.

By using biodegradable adhesives, converters ensure that their products are suitable for recycling without worrying about the waste from consumables. Because Tecbond 214B breaks down naturally leaving behind only water, carbon dioxide, and organic material, it significantly reduces the environmental footprint of packaging waste. Composed of 45% bio-based materials, Tecbond 214B is certified to ASTM D6400 and EN13432 standards, ensuring its complete biodegradation under industrial composting conditions and its ability to disintegrate without leaving harmful substances behind in the environment. This perfectly aligns with the growing consumer demand for packaging solutions that support the environment.

This environmental performance is achieved with no compromise on quality. Suitable for a wide range of uncoated cardboard and paper substrates, Tecbond 214B can be used in various packaging applications, from wrap-around cartons to POS display boxes. Tecbond 214B offers the same high-quality bonding and fast setting times as traditional hot melt adhesives, with high tack levels and near-instant bonding with substrates after application and compression. This means packaging converters can improve their sustainability without sacrificing efficiency or product quality.

Tecbond 214B stands out as a prime example of how biodegradable hot melt adhesives can support the corrugated and carton packaging industry.  As more brands commit to sustainable packaging goals, technology like this can help converters demonstrate their commitment to the environment, reduce waste, and position themselves as preferred suppliers.
