Our Pearl story began in 2015 as a simple project to develop new solutions for glass jars used for storage and home cooking. As we began to take a deeper look into the history of canning, we rediscovered a rich heritage of beautiful glass containers from an era where plastic was non-existent and reuseable glass was the standard. Inspired by these designs, we became motivated to transform them into a present-day innovative product.

For decades, jar closures have been the main development focus and throughout history with many solutions becoming patented over time. Famous jar brands from the past, such as Mason, are still recognised today. However, as times changed, the demands of packaging changed with them. Healthy living, convenience, sustainability, and recycling are some of the few factors impacting the evolution of modern food containers. We kept this in mind, but inspiration and nostalgia for historic closure designs remained at the forefront of our project.

As we started to re-think classical glass swing-top jars we were reminded that a glass jar and a glass closure were already quite perfect for reusability and the preservation of healthy food. From here, the next step was clear, to incorporate a selection of materials for the jar closures offering similar benefits but for different functionalities. Besides glass, we selected stainless steel and reusable gaskets as core elements next to glass to elevate our designs.

At this stage, our Pearl project became challenging as we were entering areas that still had to be developed technically. We followed 2 types of sealing gaskets, both perfect for hygene and re-useablity. Both have important different qualities, so we decided to offer both of them. We know this might be  a bit confusing, but our goal is  perfection.

TPE in medicine quality: Perfect for products with Oil (Feta in Olive Oil, chocolate cream, but as well cosmetics) and alkohol (Moonshine Whiskey, fruits in Grappa,…) and storage. Natural rubber: Perfect for canning and storage.


A challenging and ambitious project like Pearl, needs a vast amount of knowhow from various areas. We were lucky to convince Estal Packaging in Barcelona to become one of our partners. Especially as Estal is today the leading innovator in glass packaging worldwide and hepls to bring packaging specialists from different areas to us. That is why Pearl can offer so much new intelligent and competent solutions today. 

We are excited to have laid the foundation for more innovative and sustainable new products to come and we hope you love our products. Any suggestions welcome.
