This may involve purchasing large rolls of plastic film such as biaxially orientated polypropylene (BOPP) which is then printed to the customer's design and coated with cold seal adhesive for use on high speed packaging machines.
It is normally produced in large rolls which are slit on slitting machines into smaller rolls for use on packaging machines.
