UniTite Bio seals are versions of the UniTite 411, 413 and 414 models, produced with a special biodegradable BioSphere additive. Biodegradable seals moulded with this additive exhibit greatly increased rates of biodegradation compared to normal plastic materials, even when disposed of in landfill or other anaerobic environments.

Reports demonstrate that biodegradation can be increased 200-fold, meaning that plastic can fully biodegrade into harmless materials in years rather than centuries. This is in contrast to other types of additive which do not fully breakdown the plastic, and contribute to the problems of microplastics in our environments. Inclusion of the biodegradable additive does not affect the strength or performance characteristics of our security seals when properly stored or in use; seals only degrade when exposed to the microbial environment of landfills.
