Styrolution today announced it has entered into an exclusive supplier agreement with Dienes to supply the packaging specialist with its transparent specialty grade, Zylar® BX6503 (methyl methacrylate-butadiene-styrene copolymers). Ideally suited to extrusion blow molding, Dienes is using the grade in the production of highly transparent canisters of over one liter capacity. The application is unique due to the high level of clarity Zylar offers in comparison with other materials, such as polyethylene (PE). The first canisters will be sold starting in April 2013 by Ernst Vertriebsgesellschaft mbH, a specialist in industrial liquid containers. The joint project between Dienes Packaging and Styrolution is being supported by tools from POLY-TOOLS bennewart GmbH.

Key points:

  • Zylar BX6503 is characterized by a combination of excellent clarity and toughness. The material also cools more quickly during the canister production process, thus enabling Dienes to achieve higher production output than with conventional high-density PE.
  • Due to its specific gravity advantage, flow properties and processing temperatures, Zylar offers overall cost and material savings over competitive transparent materials, such as polycarbonate or polyester.
  • With Zylar, the process of producing an integrated handle is made possible in one step with less shrinkage than with other products, such as polyethylene terephthalate glycol-modified (PET-G). Further, customers who normally use PE can utilize the same production tools used in extrusion blow molding of PE, thus offering them processing and cost advantages.
  • Zylar also provides customers greater flexibility in placing the neck and opening of a canister not only in the middle but also on either the left or right side of the container.
  • An additional advantage of Zylar-based canisters is that shrinkage for inline labeling is significantly reduced in comparison with semi-crystalline material, thus effectively eliminating the presence of wrinkles or bubbles in the label.

Klaus Dienes, CEO and owner, Dienes Packaging: “We searched long and hard for the right material that would enable us to use our existing PE extrusion blow molding technology to produce high-quality, transparent canisters that would stand out from the opaque, PE-HD-based products on the market.

Through the cooperation with Styrolution and our use of Zylar for the canisters, Dienes Packaging has gained a competitive edge in terms of product appearance and performance.”
