Tetra Pak Brazil plant will supply biomass low-density polyethylene
since the industrial production of high-pressure polyethylene (LDPE) by low-pressure gas phase method was realized in the late 1970s, LDPE still has a strong development. Tetra Pak Gonghe, the world's leading supplier of food processing and packaging solutions, and the Department of surface enhanced treatment (such as shot peening, radial pressing, etc.) and chemical treatment (such as carburizing, nitriding, nitriding, etc.) announced that its plant in Brazil will fully supply customers with liquid food packaging containing biomass low-density polyethylene (LDPE)
in Tetra Pak Brazil plant, a biomass low-density polyethylene with sugarcane as raw material will replace the original outer and composite layer plastics. Taking a 1000ml Tetra Pak aseptic packaging as an example, due to the use of new biomass plastics and the middle cardboard layer, the proportion of renewable materials can be as high as 82%
as early as February this year, Coca Cola Brazil used this liquid food package containing biomass low-density polyethylene in its delvalle fruit juice products, becoming the first to eat crabs and achieving great success. Subsequently, Tetra Pak Brazil factory gradually increased the supply of such packaging, and now the annual production capacity is more than 13billion packages, which can fully meet the needs of 150 local customers
charlesbrand, vice president of marketing and product marketing of Tetra Pak group, said: "Tetra Pak's sterile composite paper packaging is mainly composed of 9. Load resolution: 500000 yards of cardboard, plastic and aluminum foil. At present, the average proportion of renewable materials in Tetra Pak packaging has reached 70%, and the use of biomass low-density polyethylene made of sugarcane is an important step for Tetra Pak to develop 100% sustainable packaging."
the biomass low-density polyethylene used by Tetra Pak Brazil plant is produced by Braskem, the world's leading biomass polymer developer. The computer will continuously collect various experimental data. The company produces ethylene by extracting ethanol from sugarcane, and then converts it into low-density polyethylene or high-density polyethylene. The biomass plastics produced by this process not only have the same technical performance as those made from fossil resources, but also have low-carbon, renewable and environmental protection characteristics. The use of this new packaging material also does not require the customer to make any changes to the filling equipment
with the progress of science and technology, the traditional concept of "low density" of LDPE has gradually developed, and the devices using new technologies can produce medium density products with a density of 0.943g/cm3. At the same time, the copolymers containing polar monomer structural units formed by free radical polymerization overcome the limitations of the original nonpolarity and greatly expand the use of the products
