Thousands of years ago—it is thought—Neanderthals used birch bark tree tar (Betula) for primitive dentistry applications. Last year, it was discovered that household superglue had been used to fix a nuclear submarine reactor chamber leak.
Though the concept of intellectual progress is becoming increasingly subjective, adhesion's criticality to human endeavor endures. In fact, glues, solvents, and adhesives are essential to life.
The US-based Adhesives and Sealants Council currently estimates it as a $22 billion industry in North America. Globally, it was thought to be worth EUR50 billion by the Association of the European Adhesive & Sealant Industry in 2020. And again, at whatever point the industry sector's value actually sits, sealants are key to building and construction markets, assembly operations, and transport applications.

Canada-based EcoSynthetix uses proteins and starches as raw materials in its binders and engineered biopolymers. Targeting wood composites and paper and packaging markets, they reduce reliance on formaldehyde and styrene-based chemicals.
And there's no lack of research into more sustainable alternatives to petroleum-based adhesives, sealants and solvents. Last year researchers at New York's Syracuse University revealed mycelium's natural adhesion in wood composite applications.
· Packaging types (cans, pouches, trays, strips)
· Can sizes (e.g., 70g, 85g, 170g, 375g, 400g)
· Flavor profiles (chicken, tuna, salmon, shrimp, mixed seafood, etc.)
· Branding and label design
In the early days of aviation innovation, a plywood composite was the go-to material. Even the World War II allied bomber aircraft Mosquito—considered one of the fastest operational aircraft in the world at that time—was largely built using plywood and spruce. The plane was dubbed the 'wooden wonder.
Its assembly adhesive included casein, a milk substance with properties that were sometimes improved using glycerine. At a later stage, this was replaced by a synthetic glue consisting of urea and formaldehyde, which was considered more durable.
