Packaging material and container

A packaging material having a paper layer, a first coating layer and a second coating layer laminated in this order,

• said first coating layer comprises a first material and a second material, wherein the first material is a natural rubber or a derivative thereof, and the second material is a material selected from natural resins, waxes and derivatives thereof having permeability into paper, and
• said second coating layer has oil resistance and consists of a biodegradable material.
