Forty years ago, Sidel launched its first commercial blower to produce PET bottles for the beverage industry. Since then, the company has been supplying and pioneering innovative PET packaging solutions for the beverage and the food, home, and personal care (FHPC) markets to meet the growing and fast-changing consumer demands. Through its extensive PET packaging and engineering expertise, combined with unique package design and blowing process capabilities, Sidel has been strongly supporting the market in the use of PET and will continue to do so as PET is the optimal sustainable material for packaging.

In 1980, Sidel introduced the world’s first commercial production solution to package beverages in PET – the SBO blower (In French – Soufflage Bi-Orienté – meaning Bi-oriented blowing) for carbonated soft drinks (CSD). The company has driven many performance improvements in PET bottling technology that cover all beverage and FHPC categories, achieving considerable advances in complete lines’ productivity ever since.

 

Guillaume Rolland, vice president for PET and Sensitive Products Portfolio at Sidel, explains the fundamental values that underpin the development of EvoBLOW, the latest generation blow molder by Sidel, “Throughout all the advances in equipment and packaging innovations, our underlying objectives are answering industry requirements in terms of best in class product integrity and superior package quality as well as providing maximum efficiency, lower total cost of ownership and sustainable competitiveness. Another key target is to ensure optimized production flexibility allowing easy handling of multiple SKUs and focusing on energy savings and the reduction of raw materials’ consumption to minimize the environmental impact.”

To make the most of the EvoBLOW, its integrated equipment intelligence and very responsive management lead to continuous production optimization and more comfortable maintenance services. It combines reactive automation with innovative technologies of connected machines and real-time data analytics. Unparalleled bottle quality can be reached with the patented blowing process control and self-regulation solution — IntelliBLOWER. It automatically detects and eliminates bottle process deviations to ensure production consistency and quality. Simplified and intuitive operator interventions, smart notifications for better reactivity, and reduced maintenance time contribute to improving productivity.

Expanding packaging innovation & performance boundaries

PET packaging industry has been developing ever more rapidly since 1980, although the importance of innovative and durable bottle design has remained. Sidel has been instrumental in some of the most effective, attractive PET bottle designs in liquid and FHPC packaging by always focusing on innovative packaging design and recognizing market trends to create original, eye-catching shapes that support producers to differentiate their products in a highly competitive and fast-paced market.

Sidel’s commitment to packaging design also includes driving initiatives in right weighting, which have, for example, seen weight reduction for 0.5 L format PET bottle for still water by over 70% between 1985 and 2019. For instance, Sidel’s X-LITE bottle, introduced in 2019, has achieved a weight of just 7 grams for a 0.5 L format PET water bottle while still maintaining a top-load performance, it said. This is possible due to the extensive blowing process capabilities of Sidel EvoBLOW.

Four decades of PET blowing innovations

Sidel said, in 2020, a Sidel EvoBLOW line produced 90,000 bottles per hour (bph) on the world’s fastest production line for water, almost 25 times faster than the SBO blower from 1980 was running at 3,600 bph. Since introducing the first PET bottle, Sidel has been the key driver behind numerous innovations in the packaging industry. With more than 7,000 SBO blowers running worldwide, blowing technologies by Sidel have become the standard. Affirmation for this statement may be found in the company’s long-lasting partnerships with key packaging players and the many repeated orders, which demonstrate the confidence in Sidel’s blowing expertise.

From the process perspective to machine configurations, Sidel claims to offer the highest level of blowing configurability to ensure the most tailored solutions regarding specific market needs. Available as a stand-alone or integrated machine, it can be combined with other functionalities like filling and capping in Combi Blow Fill for all types of processes (regular, aseptic, and ultra-clean with Predis dry preform sterilization, heat resistant blowing and hot filling, preferential heating for flat containers).

It can also be combined with labeling and filling, as in the Super Combi, an all-in-one, smart solution for water production and carbonated soft drinks. It can also be associated with the Actis plasma-coating and filling solution to extend beverages’ shelf life and enable package light-weighting. Simultaneously, the Combi Blow Deco claims to ensure fast, safe manufacturing and decoration of empty containers.

Packaging quality across PET, ref-PET, and r-PET

Said stated that its blowing technology has always met the changing needs of consumers and environmental challenges. In addition to work on reducing energy and consumption of raw materials to a minimum, Sidel has always been working to keep the blowing process as optimized as possible to deliver the best bottle quality and performance for all types of PET resins – virgin and recycled PET (r-PET), one-way and refillable PET (ref-PET), transparent and opaque, monolayer and multilayer.

Due to legislation that reduces the consumption of plastic raw materials and, thus, the carbon footprint, the ref-PET, and the r-PET bottles have been becoming more and more popular sustainable plastic packaging alternatives in recent years. In the production of ref-PET bottles, Sidel has been the right partner to deliver refill blowing processes for more than 30 years. The specific heat-resistance blowing process ensures optimal packaging specifications to sustain the ref-PET bottle’s structure across many uses and withstanding the durability tests (washing cycles).

According to the press statement, the Sidel electrical mold heating allows a very accurate blowing process, ensuring highly consistent ref-PET bottle quality. This can also be combined with Sidel capabilities in bottle designs, in-house washing evaluations for refillable bottles, ref-PET sorting line engineering, and very sustainable bottle washer solutions (Swing range).

Sidel said that it has also supported all the industry players who introduced r-PET bottles to the market more than 20 years ago. PET is indeed the only plastic packaging material that is 100% recyclable and suitable for direct food contact with closed-loop bottle-to-bottle recycling, ensuring a very low environmental footprint compared to alternative non-plastic materials. By requiring fewer raw materials and reducing waste, r-PET achieves a carbon footprint, which is nearly five times lower than when using virgin PET.

While stating its goal, Sidel mentioned that its overall goal is to offer technologies with wider blowing processing windows to ensure consistent r-PET bottle quality while avoiding any impact of the resin quality variation due to collection methods and bottle origin. Furthermore, Sidel’s r-PET assessment platform contributes to this purpose, boosting the development and qualification of bottles with increasing r-PET content while committing to industrial performance. To do so, Sidel keeps a fundamental close collaboration with the r-PET value chain stakeholders and offers incomparable expertise to accompany the entire industry into the significant change of conversion to r-PET.

Through a holistic approach to PET packaging production, supply chains can be turned into value chains. This demonstrates how keeping continuous R&D efforts, focused on extending the frontiers of blowmoulding, continues to make an invaluable contribution to future sustainable beverage packaging solutions. Sidel said it would keep on playing a fundamental role in this process by continually innovating to ensure that packaging in r-PET will further evolve for everyone’s benefit — the consumers, the industry’s and our planet’s.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
