We’ve been told that glass is endlessly recyclable, that it’s elegant and classy, and doesn’t react to food or cosmetic ingredients. And that is certainly all true. But, for the majority of organisations choosing packaging, the best option is plastic.
Glass is made from silica which is extracted from sand. It’s a natural product which first started being used around 4000 years ago, in Mesopotamia. It has stood the test of time as being inert, safe for packaging food and drinks, and has developed a reputation as being stylish and refined. It looks great, whether it’s a crystal clear bottle for drinks, or a frosted jar for delicious preserves.
Glass can be recycled infinitely, and remains pure and food-safe, regardless of the number of times it’s been made and remade. Depending on the type of glass, it’s safe to heat too, so you can use it from packaging, to microwave or oven, to table.
While plastic has a PR issue, more and more people are realizing that it is the more cost-effective, versatile, and eco-friendly option. How is this the opposite of everything we thought we knew?
Plastic, as long as it is recycled, has a far smaller carbon footprint than glass. Contrary to populist belief, it does degrade in a similar timeframe to other packaging like paper bags or timber. A life cycle analysis shows that plastic causes less environmental harm than glass (mostly due to the high melting point of glass and freight cost due to extra weight).
That said, choosing the right type of plastic is important. This is important for food, beverage, and pharmaceutical packaging to ensure the plastic doesn’t react or leach chemicals.
In NZ, we don’t recycle everything in the country, so choosing a plastic type that is recycled inside NZ is important to maintain low miles and high levels of recycling.
Somewhat controversially, there is no circumstance where glass is 100% the best answer. While it:
All of these things can be achieved by plastic too (silicon can be used in the oven). Moreover, plastic achieves all of this while being more environmentally friendly. However, there is consumer perception to take into account, and glass is viewed as a great, recyclable, environmentally friendly option. We have an extensive range of:
