TRADE SHOW REVIEW PETplanet Insider Vol. 24 No. 06/23 www.petpla.net 27 holistic approach, Sipa has a comprehensive expert view of the complete PET bottle value chain, Paolo said. He described three production trends going on in the PET bottle market: First, there is an increasing demand for large-sized containers of more than 5 l. Secondly, and on this point Paolo confirmed Shankar’s statement, that there is a conversion from other packaging material to PET packaging. Especially glass, which is the most recent and interesting, Paolo stated. The third point Paolo drew attention to is the trend towards producing more sustainable packaging for a circular economy. In these three trends, Sipa saw a comprehensive protective performance of PET packaging. With a growth rate of 5.2% in the mineral water market and 1.3% for edible oil in PET containers by 2026, the large PET containers must not only protect the contents but also have good logistical properties. Sipa has developed more solid logistics for stable 20 l PET stackable containers. The 20 l solution is suitable for safe transport to remote locations worldwide. Thanks to in-house packaging development and implementation on the complete production line, the PET container could be supplied with a weight saving of 50% compared to the usual alternatives HDPE or aluminium. The empty container weighs 500 g and can be produced on the Sipa XForm or SFL XL machinery. Coming back to the second point of material conversion, Paolo explained the reason why the conversion from the material glass to PET has taken place and continues. Paolo referred to the high energy prices and thus the high production costs. This resulted in a great shortage of glass bottles, especially in wine but also in other industries like cosmetic packaging. Sipa has developed a patented solution for a sparkling wine PET bottle. This unbreakable, user-friendly PET bottle can conserve liquid for 24 months. It has a look-alike traditional cork neck-closure solution with a solid base to maintain the shape of the bottle. It can be filled on existing filling lines and offers benefits in terms of production costs, material savings and a reduced environmental footprint. Paolo pointed out that the market is ready to accept the light and smart solution for PET sparkling wine bottles. Another example of the conversion to PET packaging material was developed by Sipa for the cosmetics packaging industry. With all the advantages of PET packaging in terms of break resistance, colours and flexible design, Sipa presented a new PET perfume bottle. According to Paolo, it offers an excellent consumer experience and saves 80% in weight. With its easy transport properties and low greenhouse gas emissions, it is a cost-saving and environmentally friendly package. The third point Paolo made is Sipa’s contribution to the production of sustainable packaging solutions. Sipa refers to the three main topics reduce, reuse and recycle. By reducing the weight of a bottle, using refillable or reusable containers whenever possible and strongly encouraging recycling, Sipa is promoting its sustainable growth. Sipa accompanies its customers from the first design idea to the finished bottle to produce sustainable packaging. The concept is called AWArPET which pushes not only the design for recycling but also taking the upcoming regulations like SUP or PPWD into account. The use of rPET plays a major role. As soon as rPET is used, the CO2 emission is reduced. At every stage of the bottle’s development, Sipa pays attention to sustainable treatment, e.g., in terms of neck sizes, body & base design, label / labelless, tethered caps, use of resins and additives, colourants etc. Paolo added, that from a technical point of view Sipa has well established machine systems (XForm, Xtra & Xtreme Renew) to process 100% rPET paying special attention to rPET material, e.g. with a flexible oven or vision systems. Paolo mentioned that now 100% rPET is not sustainable, that it is an operational question which needs to be solved with the support of legislation and government assistance. Sipa also introduced a labelless rPET bottle fitting perfectly in the AWArPET concept. It is a new concept of bottle design which embedded the label. The more transparent container saves plastic material, colourants and glues. A new mould manufacturing is necessary to finally show all wanted and needed information on the bottle. Special attention should also be paid to blowing pressure management. Finally, Paolo summarised the full process knowhow to enhance the protection of Sipa’s PET packaging. “Sipa combines its knowledge of materials, its comprehensive packaging know-how - from preform to secondary packaging-, its flexible filling machine systems and its complete line capability - with its sustainable concept”, Paolo concluded. After the PET market analysis, the markets and trends of the PET bottle, a novelty from the preform manufacturing process rounded off the PETinar. PETplanet was very pleased to be able to welcome back an old friend, an absolute expert in preform production, for his presentation on the new ISO Technology that StackTeck incorporates in their preform mould hot runners, supplied exclusively by Yudo. Improving the moulded preform quality consistently – ISO Technology Rick began by explaining that the name ISO refers to isometric, a threedimensional representation of an object.
