Co-extruded film which used to be mainly for meat and cheese applications have
exploded in terms of other packaging applications with the demands towards pre-cooked,
case ready meats. These films are now used in flow pack processes, vacuum packing,
gas flushing and other modified atmosphere applications.
Our films are designed to provide either medium or high barriers to oxygen, other
gases and water vapor and extend products shelf-lives. We are able to provide
films which are forming web which draw on Mulitvac and other equipment and the
top webs which form the lids for the packages.
Our coextrusions are available in 3, 5,7,10 or 14 layer compositions which are
all custom made to the user’s specifications. Frequently we can help design a
product solution which allows the converters to achieve the demands of the package
but with thinner films. And coextrusions have the added benefits for converters,
because they are made in one extrusion process, they are generally more economical
than laminations and the risk of delaminations is virtually zero.
Generally, our coextrusions are combinations of nylon (Polyamid or PA), polyethylene
(PE) or similar seal layer materials and can be produced with or without EVOH
for extra barrier.
In addition, for customers who wish to have printed films, we can add a laminated
top layer, typically PET or PP with a high gloss which is reverse printed, so
that the package is highly attractive to consumers.

- Our films strive to provide the following attributes and advantages:
- Exceptional seal strength
- Flex crack resistance
- Tie layers which give superior bond to handle oils, chemicals and other contaminations.
- Antifog if necessary
- UV blocking
- High mechanical strength
Due to the specialized nature of these films, datasheets are not generalized
but will be provided once your specific needs have been analyzed and a custom
formulation and solution is proposed by our sales specialists.
