Developing degradable plastic packaging materials and gradually phasing out non-degradable plastic packaging materials is the trend of world science and technology development, which is one of the hot spots of material research and development.

The main characteristics of glass packaging materials are beautiful, health, corrosion resistance, low cost, and is inert material, small pollution to the environment; The disadvantage is that it is fragile, bulky and expensive.
Because paper products packaging can be recycled again, after using a small amount of waste in the natural environment can be natural decomposition, no adverse effects to the natural environment, so the world recognized as paper, cardboard and paper products are green products, accord with the requirement of environmental protection, to control white pollution caused by plastic can play a positive role in alternative. eco-friendly food packaging also include paper packaging.
The above four are the most common and most environmentally friendly food packaging materials. At the same time, more and more environmentalists adopt reusable textile bags, which can reduce environmental pollution.
