Glass is another common material for packaging foods and beverages. This is because glass has a non-porous surface, guaranteeing that no harmful chemicals leak into the food or beverage when heat is applied. While plastics are great for storing cold beverages, there are still concerns with the material's health safety risks due to its porous and permeable surface. Glass is a standard in most industries for many years, and not only in food and beverage applications. The pharmaceutical and cosmetic sectors use glass to protect and maintain the efficacy of sensitive creams and drugs.
