I'm pretty sure that just like me, you've noticed that more and more products in Tetra Pak® cartons (from beverages to broths, soups, sauces and even dog food) are filling the supermarket shelves. Well, that is the result of manufacturers embracing Tetra Pak® containers because of their environmental friendliness and portability. And with more and more consumers realizing that this form of packaging is highly functional because it provides easy handling, easy storage and easy consumption, we can all expect to see more products in Tetra Pak® cartons.
So what exactly are Tetra Pak® cartons and what are they made of? Well, Tetra Pak® cartons are containers which are intended to keep products fresh and delicious for a long period of time without the need for preservatives. They were first launched in 1952 by the Swedish food packaging and processing company, Tetra Pak. They are widely used around the world and was introduced in the US in the early 1980's.
Tetra Pak® cartons give products long shelf life through their special layers which include the following:
1) Internal polyethylene layer which seals in the liquid
2) Polyethylene layer which is needed for lamination process
3) Aluminium foil which provides a barrier to oxygen, flavours and light
4) Polyethylene adhesion layer which is needed for lamination process
5) Paperboard which gives stability and strength
6) Polyethylene layer which protects food from external moisture

Tetra Pak® cartons are made of 70% paper, a renewable resource, from selectively harvested, re-grown trees that are FSC (Forest Stewardship Council) certified. They are recyclable and in fact result in 60% less landfill waste than cans. The goodness of this type of packaging doesn't end here. They are also light and compact and offers greater packaging efficiency, holding 96% contents in just 4% packaging. So products in Tetra Pak® cartons ship more efficiently, requiring fewer trucks which means less fuel and energy, resulting in reduced CO2 emissions into the atmosphere. A lot of consumers prefer them because they are very easy to handle and they are easy to stack and store in the pantry. And the best thing is that they keep the food in its original flavor and free from metal taste that canned foods have. Considering all these, it's clear that choosing products in Tetra Pak® cartons is a way to live smart. Not only are you helping the environment in your small way, you are also making sure that you are eating fresh tasting and BPA-free food.
