TETRA PAK QUALITY
Aseptic technology keeps food safe and flavorful for at least twelve months, without refrigeration or preservatives. It allows food to retain more color, texture, taste and nutrition. Our aseptic packaging offers a variety of package shapes, consumer convenience and economies in energy and packaging materials.
Our aseptic process ensures that both food and packaging materials are free of harmful bacteria when food is packaged. Everything in the production chain must be commercially sterile. That includes food and packaging materials, all machinery and the environment in which the packaging takes place.
Our aseptic packaging method passes flat, unformed packaging material through a heated hydrogen peroxide bath. A hydrogen peroxide concentration of 30% is heated at 70°C for six seconds. Hydrogen peroxide is then eliminated from the packaging material using pressure rollers or hot air.
The main material in all our packages is paperboard. We 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 aluminum foil. Aluminum foil protects against oxygen and light to maintain the nutritional value and flavors of the food in the package in ambient temperatures.
