Thanks to the evolution of the dairy market and innovation in its packaging, today it costs less, does not go to waste, lasts for months without refrigeration, transports more with fewer resources and is more affordable.
In the 70’s, Plastilene entered the food market producing plastic milk packaging with very high sealing conditions, which prevented leaks. At that time pasteurized milk was marketed. What was its limitation? It lasted only a few days and you had to refrigerate it!
Around the 1990s, the first packaging machines with UHT milk process arrived in the country, which made ultra pasteurization and packaging of milk. It was good news for the conservation of the product, but the plastic used in the packaging was imported. The challenge was to produce it in Colombia.
In 1997, we decided to support the dairy market in its need to extend the shelf life of its product. The key was to guarantee light and oxygen blocking!
This required us to have a multilayer extruder to produce LDPE films with high-performance barrier resins that would preserve the properties and vitamins of milk, keeping its nutritional and safety conditions intact. We also developed inks resistant to the hydrogen peroxide bath required during packaging process.
The milk bag, a national product, became a great alternative because it weighs up to 4 times less than other packaging, uses materials that are compatible and facilitate its recyclability, has up to 73% less carbon footprint than other packaging and affects global warming less, in addition to the properties of maintaining milk quality for months and facilitating marketing.
Plastic from milk bags can be recovered in large proportions and in Colombia we have already started!
