The packaging solutions leader SIG celebrates its 70th anniversary of bag-in-box Packaging innovation in 2022 from its headquarters at NEUHAUSEN, Switzerland. The bag-in-box technology marked its 70-year anniversary during 2015. Since its introduction in 1955 as a safer liquid transport solution the technique developed into an essential component of SIG’s integrated packaging system which now expands worldwide across multiple industries.
American chemist William R. Scholle developed the first bag-in-box design which became quickly adopted by foodservice and beverage as well as chemical and agricultural industries. SIG’s 2022 acquisition of Scholle IPN integrated the technology into their full portfolio which launched an era of intelligent sustainable packaging innovations.
The company transformed a single innovative product into an international packaging industry standard.
The bag-in-box system has become one of today’s most adaptable packaging formats in the market. SIG has enhanced this single innovation into a complete ecosystem of films, fitments and patented filling equipment that serves an expanded range of applications including dairy products, wine, juice, cleaning chemicals along with agricultural liquids.
The years have brought market needs forward as SIG has utilized each generational transition to predict upcoming demands.
- 1950s–1970s: The company introduced as well as molded fitments and aseptic solutions.
- 1980s–1990s: The company released flexible dairy packaging bags with built-in aseptic protection features which worked with high-speed filling systems.
- 2000s–2010s: The company created unique barrier membranes together with dedicated packaging solutions for water applications.
- 2020s: The company delivered recycle-ready films that earned APR recognition for achieving their highest sustainability criteria.
Smart Dispensing Meets Foodservice Needs
The connector technology developed by SIG creates significant improvements in foodservice operational efficiency. The company delivers extended shelf-life combined with lower system contamination and minimized product loss through its automated design for beverage dispensers. Systems today remove 99% of product from production lines which results in better operational KPIs and decreased costs.
The current SIG design represents two decades of continuous evolution according to CEO Samuel Sigrist. The bag-in-box enjoys standing as both an internationally recognized groundbreaking innovation and a strategically advanced solution. The company takes pride in its dedicated team members and anticipates many exciting prospects which this technology brings to future generations.
A Clear Sustainability Path
The Australian market welcomed SIG’s new bag-in-box water packaging solution that meets recycling standards as part of its effort toward creating circular packaging systems. The SIG Terra RecShield material system uses a proprietary polymer to replace aluminum through a material innovation that maintains its performance while making the entire installation recyclable.
Glenn Wiechman the VP of Global Business Line – Bag-in-Box highlighted the roadmap for the long term during his presentation. We have been leading the industry for 70 years yet our focus today is on footprint reduction to make a sustainable packaging future possible. Our products serve both commercial and personal fluid delivery needs in regions throughout the worldwide community.
Looking Ahead: Engineered for the Future
The principle that defines SIG directs towards better invention through engineered future readiness. Thanks to the improved product-to-package ratio and lightweight materials together with reduced emissions the bag-in-box stands out as one of the best environmentally friendly packaging solutions.
As part of its historic achievements SIG invests twice as much into innovation to create bag-in-box solutions which fulfill current manufacturing requirements while following upcoming packaging standards that prioritize sustainability with performance and efficiency.
