What is a double wall coffee paper cup?

See the photo below: there are 2 layers. 

One layer exterior of the cup, and insulated between these 2 walls, so it can insulate heat, better protecting your hand.

It will not leak, since there are 2 layers, the cups are more sturdy, strong and tough.

Only very hot coffee, hot tea we suggest double wall cups.

If normal weather drinks, to better protect our environment, single wall cups are good enough.

Single wall cups will save paper material, energy, reduction in carton size, save transportation cost, save money.

So choose a proper cup, provide more options for your clients, but try to be more environmental friendly.
