Glass Available in several colours - commonly brown, green and clear - glass is a transparent and moisture resistant packaging material. The drawbacks of glass packaging are that it is relatively heavy meaning that it can be comparatively expensive to transport and it can be easy to break if it is not protected by other packaging in transit. Glass manufacturing is extremely energy intensive. Sand, sodium ash and lime are heated to around 1500 degrees C. It can be easily recycled and a percentage of most glass will come from recycled sources. Reusing glass packaging is a good option, for example returnable bottles are reported to be able to be reused up to 30 times. Glass is a traditional material that is often used to bring added value to products particularly in the retail environment. It is typically used for bottles and jars.
