The preferential heating system (PH) developed by the KHS Group now enables bottlers to achieve perfect bottle quality even with extremely oval bottles in an energy-saving, safe and reliable process. Especially when processing cleaning agents, laundry detergents or personal care products, which are very often filled into oval PET bottles, this process has many advantages. The systems provider now also offers this option for its successful InnoPET Blomax Series IV stretch blow molder. During preferential heating the preform is selectively heated according to its later bottle shape to prevent any uneven distribution of materials. Preferential heating is made possible by a special heater section at the end of the heating segment. Here, the system first rotates the PET preforms through the heater to obtain a basic heating profile. In the downstream PH section rotation is stopped, giving the preform its selective heating profile.
Also on show at K 2016 will be innovative systems for special stretch blow molding requirements, such as PET packaging with 70-mm necks. These receptacles are known as wide mouth containers and used for various types of food packaging. For this purpose KHS has developed a heater box which is specially tailored to suit the wide neck preform and thus requires very little heating energy. In addition, when the containers are changed over, no manual conversion is needed. The heater box is available for various container formats on the InnoPET Blomax Series IV.
In the form of a video presentation KHS will also be showing visitors its future-proof block system; with the KHS InnoPET TriBlock the KHS Group has now launched a filling and packaging system for PET bottles to market which incorporates a stretch blow molder, labeler and filler. With consistent neck handling KHS also enables lightweight PET to be processed.
From the initial design to the ready-to-produce bottle
Another focus of the trade show will be sustainable bottle design. With its Bottles & Shapes™ program KHS GmbH offers beverage and food producers an all-round service which starts with individual suggestions for possible designs and ends with a bottle that is ready for production.
One of the developments to come out of the Dortmund systems provider's Bottles & Shapes™ program is a lightweight 1.0-liter PET bottle for milk and mixed milk beverages. Weighing just 20 grams, it demonstrates what the milk bottle of tomorrow could look like: attractive, light – and easy on resources. In order to protect the milk against external influences, two different types of UV light barrier are used. Unlike the classic milk carton, this bottle is fully recyclable.
