Benefits of technology

[0031]According to another embodiment of the present invention, the at least one reverse printed EB ink layer, the EB treated OPE film, the laminating EB layer, and the sealant polyethylene film are cured in one step, causing the OPE to become cross-linked.
[0032]According to yet another embodiment of the present invention, there is provided an environmentally friendly efficient process to make recyclable flexible packaging with a reduced number of production/operation steps required when using EB inks & EB laminates.
[0033]According to another embodiment of the present invention, there is provided a process of making recyclable flexible packaging with the benefits of quicker production times, elimination of long storage times, excessive storage costs, and long-term curing issues during production.

Problems solved by technology

Unfortunately, the existing technologies are frequently not recyclable, or otherwise difficult and expensive to recycle.
As a consequence of this poor recyclability, these multi-layered packaging materials create mostly unwanted non-biodegradable waste.
Another global emerging issue is the increased awareness of plastics in our landfills, oceans and rivers, and the resulting demands to reduce our global carbon footprint.
The materials used in most of the currently available flexible packaging structures are not considered readily recyclable because of the presence of two or more dissimilar films or layer materials used to manufacture the final package.
