How does amber glass compare to clear or green glass in terms of light protection?

Amber glass offers superior protection against UV light compared to clear or green glass. Clear glass provides virtually no protection against UV light, leaving contents highly vulnerable. While green or blue glass offers some minimal light filtration, they do not block the full range of damaging UV wavelengths as effectively as the darker, specifically formulated amber glass.

Is amber glass considered an environmentally friendly packaging solution?

Yes, amber glass is considered an environmentally friendly packaging solution primarily because it is 100% and infinitely recyclable without loss of quality. Its production from abundant natural resources (like silica) and its ability to be melted down and reformed repeatedly contributes to resource conservation and reduces energy consumption compared to manufacturing virgin materials.

Besides light protection, what are the other key material advantages of using amber glass?

Other key material advantages include its chemical inertness and durability. Being non-reactive, the glass prevents any chemical interaction between the container and the contents, thus safeguarding the product's purity and taste.
