Tetra Pak's philosophy is simple: the savings brought by packaging exceed its own costs. Tetra Pak packaging is mainly based on renewable materials and can be recycled. At Tetra Pak, the processing and packaging system aims to minimize the consumption of raw materials, energy and other natural resources during the product manufacturing process.
Tetra Pak packaging material consists of cardboard layer, polyethylene and aluminum foil. For each packaging form, the only material that comes into contact with food is food-grade polyethylene. Paperboard provides toughness for packaging, plastic plays a role in preventing liquid leakage, and aluminum foil can block the entry of light and oxygen, thus maintaining the nutrition and taste of the product.
Tetra Pak pioneered aseptic technology in 1960s, which changed the liquid food industry forever. Aseptic technology is listed as the most important food science innovation in the twentieth century. Different from canning and bottling, Tetra Pak aseptic processing makes liquid food better retain its color, texture, natural flavor and nutritional value. Tetra Pak aseptic packaging can remain sterile for up to one year without disinfection or refrigeration.
The core of Tetra Pak aseptic packaging technology lies in aseptic packaging content, filling and sealing packaging in a hygienic environment. Tetra Pak's normal temperature packaging department has the most complete product portfolio in aseptic paper packaging industry, including various innovative shape openings and straw applications.
Tetra Pak packaging, as a product packaging form, has been widely used in many fields such as milk, juice drinks and so on. Its many advantages have been widely recognized by people, and this packaging form can be trusted in environmental protection, color realization, hygiene standards, nutrition preservation and so on. There are many kinds of such packaging forms, such as tetra pak cans, tetra pak pillows, tetra pak cups and tetra pak bricks.
In foreign countries, recycled tetra pak packaging materials have been separated by hydraulic pulper, and fibers, plastics, aluminum and platinum have been dispersed for decades. The recycling rate of beverage boxes after consumption has also increased year by year. In 2000, the tetra pak collected in the European market reached 200,000 tons. Paper mills in Taiwan Province Province, South Korea and Japan also started recycling many years ago, and their fiber recycling products mainly include wrapping paper, envelope paper, corrugated paper, fruit bagging paper, pulp board and other forms.
Since 2002, some paper mills using waste tetra pak fiber have appeared in China, including Inner Mongolia Autonomous Region, Zhejiang, Guangzhou, Shandong and Beijing. According to statistics, as of June 2005, 5438+ 10, the total amount of waste tetra pak used for hydraulic pulping in China reached 8000 tons. Abandoned tetra pak mainly comes from community waste collection stations, airports, schools and other public facilities in large and medium-sized cities, as well as dairy products and beverage factories all over the country. Products mainly include wrapping paper, corrugated paper, pulp board and so on.
