Krones and Alpla have developed a reusable PET container that is also suitable for sensitive products such as juice and milk in the cold chain. The development was preceded by a joint research project.<\/p>\n

Out of the niche: Reusable PET containers tend to play a subordinate role in the packaging market for beverages. Wrongly so, as a joint research project by Krones<\/a> and Alpla<\/a>. In this material and process parameters were first subjected to a comprehensive scientific evaluation<\/strong>. Based on the knowledge gained in this way, the cooperation partners succeeded in developing a reusable PET container that also provides an ideal home for sensitive ESL (Extended Shelf Life) products such as juice and milk in the cold chain.<\/p>\n

Reusable PET with a good environmental balance<\/h2>\n

Be it due to legal requirements, voluntary climate targets or increasing environmental awareness among consumers: Sustainability issues are becoming increasingly important when choosing packaging.<\/p>

\u201eWhich type of packaging performs best from an ecological point of view depends on a variety of influencing factors and must be evaluated individually for each application,\u201c says Martina Birk, enviro sustainability programme officer at Krones<\/a>. Reusable PET containers are often not even considered<\/strong>. \u201eThey can offer an extremely attractive environmental balance, especially with predominantly regional distribution.\u201c<\/p>\n

Krones and Alpla have joined forces to utilise these advantages for a wide range of beverages. \u201eUntil now, reusable PET containers have primarily been used for carbonated soft drinks and water,\u201c explains J\u00f6rg Schw\u00e4rzler, reusable expert and project manager at Alpla. Alpla<\/a>. \u201eBut we were certain that if we could Bringing together expertise in materials science, preform design, container design and plant engineering<\/strong>, we also find a solution for sensitive beverages such as juices or dairy products. The option of a 38-millimetre neck finish has particular advantages for sensitive returnable applications.\u201c<\/p>
