Plastic bags are both a boon and a big problem. They are so useful, but so wasteful.
Today’s invention aims to offer bigger carrying capacity using less material.
The plastic carrier bag on the left has some resealable ‘ziplock’ windows moulded into it.
When the bag is loaded, on the right, the windows are opened, allowing weight to be supported by the unperforated bottom section, whilst boosting the overall space in the bag.
Obviously the bag windows can later be resealed and the whole thing reused.
