In today’s era everything is highly secure and updated with technology, well in the race of technology adaption food products are not getting back. so packaged food is the latest trend now a days to keep food safe and tasteful for a long time, specially liquid type of dairy products.
Did i said packaged food is latest trend, sorry its started a long time ago seriously, it was 1943 in sweden and the first pakaged food was milk.
Tetra Pak was created in 1951 as a subsidiary to Åkerlund & Rausing, a food carton company established in Malmö in 1929 by Ruben Rausing and Erik Åkerlund.
Tetra Pak is a multinational food packaging and processing company of Swedish origin with head offices in Lund, Sweden, and Lausanne, Switzerland. The company offers packaging, filling machines and processing for dairy, beverages, cheese, ice-cream and prepared food, including distribution tools like accumulators, cap applicators, conveyors, crate packers, film wrappers, line controllers and straw applicators.
Tetra Pak cartons are made up of six layers. These layers help protect what’s packed inside from germs, sunlight, air and adulteration. This means that the beverage packed into Tetra Pak cartons do not require preservatives. These layers are made from the following three materials:
The main material in all packages is paperboard. They use just enough to make the package stable, without adding unnecessary weight. Paperboard is a renewable material, made from wood.
Paperboard is the main material in our cartons. It provides stability, strength and smoothness to the printing surface.
Polyethylene protects against outside moisture and enables the paperboard to stick to the aluminium foil.
3. Aluminium foil
Aluminium foil protects against oxygen and light to maintain the nutritional value and flavours of the food in the package in ambient temperatures.
So to preserve liquid food products like fruit juice, milk, cheese, ice cream, other dairy products from nature’s reaction or getting spoiled, by heat, bacteria, and sunlight ;tetra layer food packaging technology used.
Now the most important question Can tetra pak be recycled?
In general, the answer is no, Tetra Paks are not recyclable or compostable as is because they combine paper and plastic – and some even contain hidden metal. Specifically, for the milk cartons with a round middle cap, you have to remove the plastic spout first to give them a shot at being compostable.
