Functional polymers - physical and chemical functionalization

The collaboration between Perlen Converting AG and the Functional Materials Laboratory aims at the physical and chemical functionalization of polymers.

Shark skin coating

Micro-structuring does a quantum leap.  A modified roll coating process allows rapid patterning with line speeds up to 120 m/min making the process most interesting for large area applications. The structured coatings excel in terms of their ultra-low adhesion. Peeling off an aggressive adhesive tape, packaging of sitcky food or easy to clean surfaces now becomes a piece of cake.

Keep-fresh packaging

Do not store apples along with bananas; is known among housekeepers. Apples release a lot of ethylene which triggers the spoilage of many fruits and vegetables. The optimal storage of fresh produce is a demanding issue for the distributor as well as for the retailer and finally the consumer. The ultimate aim is to guarantee best quality at any stage and for a time period as long as possible.

The most recent development of a catalytically active packaging material enables extended shelf-life of fresh produce. The functional coating captures ethylene maintaining a low concentration of the spoilage gas within the package. As a result your packaged bananas will keep their freshness and right ripeness.
