Replacing a Multimaterial Laminate Is Easy on a Structure Drawing. Rebuilding Its Barrier and Processing Performance Is the Difficult Part.
Flexible packaging has traditionally achieved demanding performance by combining different materials, with each layer contributing barrier, stiffness, toughness, heat resistance, printability or sealing performance. The move toward recyclable mono-material packaging changes that design logic.
A polyethylene or polypropylene structure may be much easier to place within a recycling stream, but PE and PP alone cannot automatically reproduce the oxygen barrier, aroma protection, dimensional stability, surface properties and processing latitude delivered by conventional PET, PA, aluminium and polyolefin laminates.
The technical challenge is therefore not simply to remove incompatible materials. It is to rebuild the required package performance using oriented polyolefin films, thin barrier layers, functional coatings, primers, adhesives, printing systems and sealant technologies that remain compatible with the intended recycling route. This expert-led training examines how mono-PE and mono-PP flexible packaging can be designed for demanding food, pet food, household, personal-care and other applications while balancing oxygen and moisture barrier, mechanical performance, sealing, printability, converting behaviour and recyclability.
Particular attention is given to EVOH, PVOH, AlOx, SiOx, metallized structures, water-based barrier coatings, primers, laminating adhesives, orientation and multilayer structure design, together with the practical limitations that appear when these technologies are combined. The focus is on helping you to make better material and structure decisions, rather than treating mono-material packaging as a simple material-substitution exercise.
