Sidel has made an interactive packaging optimisation tool available on its website, allowing manufacturers to estimate potential savings related to primary PET packaging based on individually selected application scenarios. The solution was developed in response to the growing importance of PET costs in current market conditions. According to the company, the tool makes it possible to analyse the impact of selected design and material changes on both costs and greenhouse gas emissions on an annual basis. Users can compare their current production with variants including modifications to the bottle neck, body and base, the use of partial labels, and the incorporation of recycled PET. The company emphasises that lightweighting packaging can support both economic and environmental targets without compromising packaging quality.
As Vincent Le Guen, vice president for packaging, moulds and line solutions, explains, "Rising and volatile PET costs represent a major challenge for customers, and every opportunity to reduce packaging weight brings benefits both in terms of financial performance and sustainability targets."
According to information provided by Sidel, achieving savings and reducing environmental impact requires a series of design and technology decisions. The manufacturer states that by reducing packaging weight and optimising design, it is possible to lower bottle neck weight by up to 40%, body weight by 35%, and base weight by 20%. The company also declares expert support in production line upgrades and mould selection following a comprehensive packaging feasibility assessment and performance qualification. In the company's view, material savings can translate into a rapid return on investment while simultaneously reducing the carbon footprint.
Technologies supporting further material reduction
Beyond the packaging design itself, Sidel also points to the possibility of achieving additional effects through the use of specific process and machinery solutions. According to the manufacturer, the EvoBlow Laser system enables an average additional weight reduction of 10% without deteriorating performance parameters. In turn, its roll-fed labelling solution with partial labels is said to reduce label material consumption by up to 75%. In the area of secondary packaging, the company points to the EvoFilm Stretch system, which is intended to reduce plastic film consumption by 50%.
According to the company, such technologies can support manufacturers in maintaining competitiveness while reducing raw material consumption. This fits into broader activities related to packaging design focused on material efficiency and emission reduction.
Tool development and company experience
Sidel notes that it has long been developing solutions aimed at reducing raw material consumption in packaging production and supporting the circular economy. The company states that it was the first to introduce industrial-scale blow moulding technology for PET packaging. It also points to the origin of its name, derived from the French term Société Industrielle Des Emballages Légers.
As Jerome Neveu, product manager in the packaging and moulds division, concludes, "This new online calculator is flexible, interactive, easy to use and available free of charge; it helps raise awareness of existing cost-saving opportunities and supports the development of packaging aligned with sustainability strategy."
