It preserves the contents’ vitamins, taste, and freshness by acting as a natural barrier to potentially harmful bacteria or changes in temperature. Even the colour of glass can make a difference! For example – amber glass provides protection from exposure to UV rays.
Glass comes from nature
Glass can be sourced sustainably because of its naturally occurring ingredients that are abundant in nature. The transformation of these ingredients results in one sole material. No other material or chemical layers are needed to complete it.
Glass is healthier
Glass is healthier than most forms of packaging because it’s non-toxic, and free from potentially harmful chemicals. Glass containers have an impermeable barrier that does not chemically interact with the products kept inside even when contained for a long time, unlike plastic. It’s also the only widely-used food packaging granted the FDA status of “GRAS” or generally recognized as safe – the highest standard. Packaging herbal supplements and vitamins in amber glass bottles with screw caps can aid in preserving the beneficial nutrients they contain, and prevent light absorption.
Glass is free from contamination
Extensive scientific research has proven that glass can protect consumer health more than any other packaging material. With no substances of glass packaging migrating into food, glass represents a safe, and ideal food packaging material with consideration to health and food safety.
Glass is 100% recyclable
Glass is 100% recyclable and can be recycled endlessly with no loss in quality or purity. Glass recycling is a closed loop system, creating no additional waste or by-products.
Thanks to its non-toxic properties, glass is one of the most suitable food packaging materials to protect consumer health and keep products safe (Dieter Schrenk, 2014). It’s exempt from European Union REACH Regulations (Registration, Evaluation, Authorisation and Restriction of Chemical substances) and is also the only widely used packaging material to be classified as “GRAS” (“generally recognised as safe”) by the U.S. Food and Drug Administration.
