"It is important for us to be understood by our supplier"

The story of ELA Wyrób folii i opakowań sp. z o.o. is somewhat typical for converters from the former Warsaw Pact region. In 1980,Eugeniusz Laskus founded the company in Celestynów, less than an hour from south east of Warsaw. Being a gardener and painter by trade he didn’t see much of an economical perspective due to the soil conditions in his home town. He decided to start his own business.

Optimized extrusion coating die systems for flexible packaging

Flexible packaging is likely the largest market for extrusion coating and is certainly the most demanding. Production volumes are great, calling for coating systems that provide the highest levels of efficiency and raw material savings while entailing the least amount of downtime. The importance of ensuring the integrity of food packaging, the precision required for printing and sealing operations, and the complexity of certain coating structures—these call for stringent standards of quality and consistency.

The gel count standard in polymerisation and extrusion

Today value adding film producers and converting companies control their production inline 100% by using highly sophisticated optical camera inspection systems. These intelligent self-learning systems recognise the exact position of every defect, take a photo of the defect and warn the operator in time. This helps to control the extrusion and converting process better and to avoid the production of waste.

The benefits of web inspection are achieved in three parts of film extrusion and converting: the process itself, the raw material or the final product.

Extrusion coating and laminating - 101

Extrusion coating is the coating of a synthetic resin molten strip and extruding it through a flat die on a substrate. Combining two inexpensive materials to make a higher performance product adds value and utility. It is a flexible coating technique used for applying various economic plastics, including polyethylene, on cardboard , corrugated cardboard , paper, aluminum foil, cellulose, nonwoven fabrics, or plastic films.
