Polyethylene and chalk to make bottles
Bio fashion increases in food containers
Drafting PU28/04/2008
In the past 30 years were consumed on Earth more non-renewable raw materials which in the history of civilization. Current climate change warn us: need to establish new references for the extraction and consumption of these resources. Therefore, the plastics industry begins to focus intensely on renewable materials: the so-called "bioplastics" are trying to make a hole in the food industry applications. A combination of materials of polyethylene (PE) and calcium carbonate is one of the latest contributions.
Within this framework of cooperation, the Swedish company producing raw materials Polykemi AB (Ystad - Sweden www.polykemi.se) presented at Interpack a new bioplastic: a polyethylene with a percentage of chalk (calcium carbonate) as filler material. This granulate from the Swedish company is called "ecoscan" (so far: "scanfill") and replaces the HDPE conventional in containers of food products.
The economical alternative
This raw presents exceptional barrier properties, improved protection against ultraviolet radiation and also surprised by their high profitability. Also presents advantages in terms of ease of processing in mould of extrusion-blown: now try the first machine of blowing all-electric Eblow 206 (d) installation of two stations in the extrusion in 3 layers. In this way they can mold for blown 5.220 milk 200 ml bottles per hour in a material EcoScan Bekum machine.
Depending on what material is compare, productions can reach up to 30 percent higher.
The new material presents exceptional barrier properties, good protection against ultraviolet radiation and ease of processing in mould of extrusion-blown.
EcoScan blown-molded
EcoScan is approved by the FDA as a food-grade, and convinces by its long durability. These physical and functional advantages are only the beginning: extraction and refining, as well as the possibility of recycling after use as a container, give as a result a positive ecological balance.
By manufacturing EcoScan already saves water and energy. Both companies rely deeply on the contribution of this material to the environment is well accepted in the market.
