AI Technical Summary

Technical Problem

Conventional blister packaging is difficult to recycle due to the use of different materials for the backing and cover, and the presence of active components like desiccants, which contaminate the packaging and prevent recycling.

Method used

A recyclable blister pack design featuring a cover and backing made from the same recyclable material, with an optional multilayer component including an active layer and a non-active layer, allowing for efficient recycling while maintaining product preservation.

Benefits of technology

The solution enables the recycling of blister packs by using a single recyclable material for both the cover and backing, reducing contamination from active components and facilitating efficient recycling processes.
