Coffee Packaging goes sustainable

Looking at Europe, around 3.2 million tonnes of coffee were used in 2018, according to CBI, the center for promoting imports from developing countries. It was acknowledging that a large proportion of this coffee has to be placed appealingly and safely at the point of sale. 

Circular Economy on sustainability concept

It becomes clear that the sustainability concept should not end with the certified bean because mainly, 1the sales packaging offers potential when it comes to the well-thought-out use of resources and assistance in a circular economy—one example of the cooperation project between process and packaging technology expert Syntegon. 

Monomaterial for Coffee Packaging

The companies developed and manufactured a PP mono-material solution characterized by excellent barrier properties and convince with unique process capability and excellent printability. The result of the best aroma and product protection combined within 100% recyclable. 
The mixing of different coffee beans does very frequently provide a highlight in flavors of coffee blends. However, when it comes to plastics, combining different materials results instead in structures that do not meet recycler approval.
According to Jens Kölble, Head of Packaging & Performance Films POLIFILM, emphasizes the importance of mono-material packaging. 

Old Concept of Coffee Packaging

For decades, coffee packaging with its aluminum-containing composite was a classic example of poorly recyclable solutions. The main reason for this packaging form’s long-lasting popularity was the lack of a representative for an aroma barrier in combination with a suitable sealing film. 

POLIFILM’s PP material 

The polypropylene (PP)-based mono-material solution from the cooperation project addresses precisely this problem. POLIFILM’s PP sealing film establishes a broad sealing window and an early seal initiation temperature, also known as SIT (Seal Initiation Temperature). The full sealing window allows more significant limits in machine settings and therefore maintains the packaging process. 
The POLIFILM developers focused on the reduced SIT of the PP sealing film. This is important when using BOPP as an outer layer to achieve a sufficiently broad sealing window in the standard heat-sealing process despite the lower temperature stability than conventional PET.
That right sealing starting point and the proper sealing temperature are decisive in the processing and beyond Kölble. They determine the following functionality as well as the flexibility of the solution. The crucial product protection provided by the packaging solution’s stability is also a critical measure for Syntegon. 
Our goal is to ensure that a consistently good packaging quality with high machine efficiency and availability and new sustainable packaging materials, says Mr. Torsten Sauer at Syntegon and adds, it is essential to support our customers in the changeover to durable packaging material. we are pleased to a company our customers to the finished product on 
Product tests with TAGHLEEF INDUSTRIES and POLIFILM films have confirmed that both can go hand in hand. Syntegon successfully processed these both into flow packs and reclosable stand-up pouches with zippers. By avoiding the use of a new group of materials in addition to the PP used, the resulting packaging can be recognized by recycling machines as PP mono-material and can be recycled without a new division. 
That concept would be applied not only to coffee packaging but also to the design of other food and non-food packagings, such as for detergent or hygiene products.
