packlock is constantly evolving and more and more applications are being discovered. Especially with button cell batteries there is the problem that infants and small children swallow the batteries and in the worst case a chemical burn follows. The packlock system offers the necessary safety here too and, in addition, these packs can be designed to be sustainable. packlock offers a child-resistant, senior-friendly and biodegradable packaging variant made of cast fibre and monofilm. The packaging is provided with a closure seal and can be hung on the usual shelves in retail stores.
