The “low pressure” (LP) base design is combining a unique design with additional venting solutions to let the air exhaust easily. Due to the optimized PET material flow, less air pressure will be required to blow out all areas of the base properly – without having any impact on critical bottle tests. The base design was implemented at several European CSD bottling plants with huge success: Blowing bottles with less than 20 bars instead of 30 was feasible in many cases and some customers were able to even reduce to 15 bars. Important note: All potential results are related to local conditions such as preferred preform design and weight, condition of the blowing machine and moulds as well as the bottle shape itself.
The LP base design can be used for new mould developments, but also can adapted to existing formats. Bottlers only need to change the base mould – there is no need to invest in a full set of moulds. Customers of Röders appreciate the quick return on investment as the energy savings will balance the input for buying new base moulds on short notice.
Röders will show this technology during this year’s Drinktec exhibition in hall C5 – both number 230.
