US-based adhesives manufacturer HB Fuller has introduced two compostable adhesive solutions for the flexible packaging market.
The company has added the SF1000CP/XR2000CP and WB1200CP/XR2200CP solutions to its Flextra Evolution brand.
The SF1000CP/XR2000CP is a 2K solventless adhesive suitable for use with several biodegradable film substrates, including bar wrap and snack packaging.
The WB1200CP/XR2200CP is a water-based two-part system designed for paper-to-film laminations. It is fully compostable according to EN13432 and ASTM D6400 specifications and fully certified by the Biodegradable Products Institute (BPI).
HB Fuller research scientist Wayne Eklund said: “When people ask for a compostable adhesive, what they are likely asking for is a package with components that can be composted. Now this can be brought to life with the help of our compostable adhesives throughout the supply chain.
“These new solutions from our Flextra Evolution product line have similar performance to conventional multi-layer packaging adhesives, show great printability and appearance, and work seamlessly with standard equipment.
“Most importantly, in industrial composting facilities, the adhesives decompose with no toxic residue, microplastics or other pollutants.”
In December, HB Fuller introduced Advantra extreme cold resistant adhesives for the pharmaceutical industry.
The adhesive grades come with hot melt advanced technology developed for extreme cold storage of vaccines and medication packaging, providing a secure bond at -70°C with tamper-evident fibre tear.
