Glass chemical stability high, is insect-resistant and moisture-proof container, some can vacuum packing. Glass bottle packing has transparency, you can see the content, not crushed, and protect dry products can also be processed into brown and avoid light, can be recycled, can be made into a certain shape design. But glass is fragile, and the heavier weight.
