Rajesh We were envisaging the use of wax paper (the same material which the soap papers themselves will be made out of). The packaging will wrap around the sheaf of soap papers like an envelope and can be fastened with a wax seal or jute twine. The third image has this illustrated on the right-hand side. I hope that answers your question!
Hi Paricha! It's an interesting idea. My team-mate and I are currently trying to work out something similar, inspired by the dabbawallas too. I had a few questions- Will Pinto 4.0 have a team of foot-soldiers that complete the task of bringing these containers from the food stalls to the workspaces and then cleaning them up after use? Also, do the office-goers have a choice of customising their order/which food stall they order from every day? And do they do this by contacting the food stall itself or the new service set up for this purpose (if there is one)?
