What is the difference between PET and glass bottles?

Here are some of the main differences between PET (polyethylene terephthalate) and glass bottles:

– Material – PET is a plastic made from petroleum, while glass bottles are made from sand, soda ash, and limestone.

– Weight – PET bottles are much lighter than glass bottles. This makes them easier to transport.

– Breakage – Glass bottles can shatter and break easily while PET bottles are more durable and resistant to breaks and cracks.

Recycling – While both glass and PET can be recycled, glass is easier to recycle and can be recycled endlessly without loss of quality. PET loses some integrity each time it’s recycled.

– Cost – PET bottles are generally cheaper to produce than glass bottles. However, glass is generally considered a more premium, higher-quality packaging.

– Safety – Glass is chemically inert and considered safe for food and drink. Some concerns have been raised about chemicals leaching from PET into contents over time.

– Shelf life – Glass provides the best protection against oxygen, light, and temperature changes so items last longer. PET allows more oxygen through over time.

– Aesthetics – The clarity and brilliance of glass are difficult to duplicate in plastic. Glass has a more premium, elegant look.

So in summary, glass bottles are seen as more premium, recyclable, and chemically neutral but are heavier and breakable. PET plastic has advantages like lower cost and weight but is less sustainable and more likely to leach chemicals.
