Packaging films are often composed of a laminated composite of PET and PE. The addition of PET provides sufficient stiffness to the film for optimum secondary processing which cannot be achieved when using polyethylene alone. However, this composite is not recyclable.
Recycle – sustainable packaging with excellent barrier properties
With its well-known EVO Ultra Stretch, Reifenhäuser Blown Film is now presenting its new solution for processing poyethylene at this year's K trade fair. The film stretching system (MDO) is already being successfully used in plant for breathable backsheet films in the hygiene sector. "The positioning of the MDO in the haul-off unit is a key factor. This is unique on the market to date. The advantage lies in the fact that the plastic can be stretched using initial heat on the four to six-fold extent. This enables us to achieve a much higher process stability and lower shrink values due to the longer cooling path. The result is a recyclable film with improved sealing properties, which can sustainably replace PET," explained Eugen Fredel, Sales Director at Reifenhäuser Blown Film.
An economically and ecologically sensible alternative
The film's simple heat sealing property also allows a high degree of efficiency in the subsequent finishing process, as it can be further processed on existing finishing equipment with no adaptations required. "By adapting the EVO Ultra Stretch to mono-material laminates, Reifenhäuser Blown Film has succeeded in offering its customers an ecologically and economically sensible, high-performing alternative within packaging production. Compared to conventional film stretching systems, the investment costs for the components are significantly lower, as are energy consumption levels due to the use of initial heat," explained Eugen Friedel. The application has already been successfully field tested by a Reifenhäuser customer. "With Reifenhäuser, you're not only buying a technically outstanding system or component. You're also getting the entire package of expertise from us, such as film recipes and processing parameters. As a result, our customers can significantly shorten their time to market and work in stable processes shortly after commissioning," added Eugen Friedel.
