History of SIG’s bag-in-box and pouch packaging
January 1, 2020
Our story
At SIG, innovation is not just a word; it’s a mission to strive for each and every day. With a seemingly endless number of industry firsts spanning the life of our company, there is no doubt that SIG has grown into one the world’s leading manufacturers of packaging products, automated filling equipment, and closures.
Scholle Packaging
Scholle Packaging was founded in 1947. As a newly founded company, Scholle invented and marketed the first bag-in-box packaging, the first of many milestones we would come to achieve as a company. Bag-in-box packaging was initially created for the use of safe transportation and dispensing of battery acid to automotive filling stations and repair shops, and it quickly found its way into other industries as well.
In the 1970s, the aseptic filling process was perfected, which allowed Scholle to further advance its initial product line into food and beverage industries, and soon entire flexible packaging systems were possible.
There’s a reason the SIG name is synonymous with bag-in-box and pouch packaging systems. We began our journey with the development of the very first bag-in-box packaging system, which assured storage of consumer items to be of high quality and safety during transportation. This is where the innovation started, but it is most definitely not where it stopped. Over the years, SIG pioneered countless ways to increase consumer convenience and safety, while expanding the quality of its packaging systems. We have many company- and industry-wide milestones under our belt. Our major achievements can be broken down and categorized into success with total packaging systems, development of filling equipment and technology, introduction into various markets, and aseptic work.
Expanding on the initial bag-in-box packaging, we have continued to evolve and create a more efficient means to package products. There have been many milestones within the company that come from just flexible packaging systems alone. For example, we were the first to:
Reliable pouch packaging systems have been at the core of our mission for decades. We have long been developing innovative and high-quality products manufacturing in clean room environments with the goal of enabling growth of pouch systems. For example, we:
The developments we have seen in filling equipment and technology truly demonstrate the lengths to which our innovative spirit can take us. After recognizing the success of bag-in-box, we implemented some improvements in technology to allow for improved overall equipment efficiency (OEE) and packaging system quality. For example, we were the first to:
Throughout our history, we have been able to break through and remain competitive in various markets. After developing bag-in-box packaging for the safe transportation of battery acid, we entered other markets with similar success. These markets include dairy, wine, soft drinks, and more. For example, we were the first to:
As a pioneer of 
When it comes to aseptic packaging, a key element is that it is free of contamination and secures the product while in transport. At SIG, we have upheld our reputation for bringing exceptional value to our customers. We pride ourselves on our ability to deliver products the way they are supposed to be experienced. Some of the groundbreaking ways in which we manage to do this are by constantly working towards more efficient solutions when it comes to aseptic equipment. For example, we were the first to:
