This durability makes them a cost-effective and low-waste solution for both businesses and consumers looking to reduce their single-use packaging consumption.

Annealing is a critical stage in the manufacturing process where the newly formed glass containers are placed in a temperature-controlled kiln called a "lehr." The containers are heated to a specific point and then cooled very slowly to relieve internal stresses created during the moulding phase. Without proper annealing, the glass would be extremely brittle and prone to shattering spontaneously when exposed to minor temperature changes or physical impact. This process ensures that the amber glass is robust enough to withstand the rigours of high-speed Australian bottling lines, long-distance shipping, and everyday consumer handling without failing.

In Australia, amber glass used for medicines must comply with strict standards set by the Therapeutic Goods Administration (TGA) and international pharmacopoeia guidelines. These regulations specify the maximum allowable light transmission levels to ensure the medicine remains safe for use.
