Across the street from the back corner of the mercado is a papeleria on the corner that has it all. We found their prices to be better than what we could get in the US for bubble wrap. It is on the corner behind Santander.

A number of the papelerias have what you are looking for.

IF POSSIBLE, try to get the packing peanuts that are made of cornstarch and are totally biodegradable. They should be available here.

Oh, yes I believe they ARE! There's a store that sells recyclable biodegradable materials like cellulose bags and disposable products for restaurants, I think including packing materials, on Paseo del Palmar about mid-block between Plaza Kioto and the DHL store on the right-hand side if you're coming from Plaza Kioto.

Does anyone know where I can find bubble wrap, boxes, and other packing materials?

Many papelerías here offer what you seek. López Impresores or down by the Mercado Municipal.

We recently used Uline online. They delivered from Monterey to Zihuatanejo. They come in lots of 10, 15, 20,25 depending on size. Strong double wall boxes and all the packing materials. Some advice; cheap cardboard will not survive any length of time with the humidity.
