Glass is 100% pure and made of three abundant natural raw materials: sand, soda ash, and limestone. Glass does not leach toxic chemicals, so it is harmless for the environment and cannot damage human health.
Glass needs no additional layers or additives to protect food and drinks, to preserve taste, avoid corrosion, or keep the fizz in drinks (known by the experts as avoding loss of gas permeability!). It does not contain Bisphenol A (a chemical that mimics oestrogen), Bisphenol AF or other potentially harmful chemicals found in some other packaging materials.
Glass packaging provides the best protection for your food and drinks because it keeps the good things in and bad things out without the need of any additives.
For instance, glass packaging preserves the vitamins contained in food and beverages, and retains its original taste, the fizz and freshness. It acts as a natural barrier against bacteria and prevents changes of temperature from affecting its content. Beer and wine producers use green and amber glass because the dark colour provides protection from UV sun exposure.
Glass is also a safe and suitable material for microwaving and freezing, while being easy to clean and sterilize. In fact, glass is able to do all of this because it does not interact with or affect the food and drink it protects.
Glass is inert and impermeable. Glass is a natural substance – its inert and able to remain unchanged. Because it is inert, glass does not react to foreign substances or absorb them. For this reason glass is the healthiest packaging material which is why laboratories and pharmaceutical sectors trust glass to protect their products against chemical or biological contamination.
Glass is gastight because of its molecular structure - it is virtually impermeable to oxygen. This is fundamental for products that are sensitive to oxygen. Ingredients such as flavourings and vitamins are therefore preserved for a long time.
