The implementation of a glass bottle for PET bottle production is often asked for premium catering. In a recent example the elaborate engraved logo in the glass bottle was taken. Manufactured were 0.5 l and 1.0 l rotary blow moulding. The bottle is made in dark blue PET and is finding its use in the field of international premium gastronomy. As an independent mould maker Kiefer manufactures blow moulds made of aluminium for all rotary blow moulding machines from Krones, Sacmi, Sidel, Sipa, KHS-SIG, SMI etc and linear blow moulding machines of Kosme, Siapi, Side, Sipa, ADS, Bekum, MAG, Tetra Pak and others. www.kiefer-mold.de Milk bottle in 100% recycled opaque PET As part of consortium comprising industrial- ists and stakeholders in the dairy sector, Société Générale des Techniques (SGT) claims to have per- fected a process for incor- porating recycled opaque PET into new UHT milk bottles. A French manu- facturer of preforms, SGT has joined a working group to develop a 100% recyclable long-life milk bottle. The research work took 3 years to complete and the results were presented at a press conference in Paris at the beginning of the year. Achieving a ʺ food con- tact” grade and a satisfactory appearance for the bottle was very challenging in technical terms. Slightly grey and glossy, the new milk bottle is claimed to offer many benefits: less material, longer shelf life for the milk and suppression of the membrane seal. The members of this consortium, including SGT, have thus demonstrated that preforms (therefore new bottles) can be manufactured by incorporating up to 100% of recycled PET in strict compliance with food standards. This “bottle-to-bottle ʺ closed loop is totally in line with the strategy dictated by European authorities. Indeed, by 2025 PET bottles will have to include 25% of recycled material. This obligation makes the ʺ bottle-to-bottle ʺ closed circuit an industrial and regulatory priority. With this new project, SGT is actively contributing to this collective challenge, that consists in developing a more virtuous and environmentally- friendly economy by prioritising the recycling of packaging and offering bottles a second life. www.sgt-pet.com
