Mitsui Chemicals mono-material packaging solution
As a member of the Circular Economy for Flexible Packaging (CEFLEX),
our mono-material packaging solution is defined based on their guidelines;
structural build-up of more than 90% PE/PP/PO, allowing for easy recycling process by recycling companies.
Polyethylene (PE) mono-material
PE is lightweight and durable thermoplastic. Representing more than 47% of global packaging market. Making it one of the most commonly recycled polymers. When considering PE as packaging material, positive and negative aspects are :
In general for PE mono-material packaging :
Positive
Excellent heat seal property, Wide range of melting point, Good moisture resistance
Negative
Poor oxygen (O2) barrier property, Low heat resistance, low stiffness
| Potential Issues | Our Solutions | Recommended products |
|---|---|---|
| Lack of stiffness | High performance LLDPE film for printing substrate | L-Smart™ |
| Low temperature resistance | ||
| Narrow temperature gap | High performance cast LLDPE sealant film | T.U.X™ |
| High performance m-LLDPE sealant resin | EVOLUE™ | |
| Low seal temperature modifier | TAFMER™ | |
| Poor gas barrier | Water based oxygen barrier coatings | TAKELAC™ WPB |
| Tie layer for barrier resin and PE, which can design high barrier PE based film. | ADMER™ |
Polypropylene(PP) mono-material
PP is another widely used thermoplastic. Representing 17% of polymers
globally produced and 17% of polymers in the packaging industry. This leads to it
being also one of the more commonly recycled polymers.
When considering PP as packaging material, positive and negative aspects are :
In general for PP mono-material packaging:
Positive
Excellent moisture barrier, Good heat seal property, high clarity
Negative
Poor oxygen (O2) barrier property, Narrow range of melting point
| Potential Issues | Our Solutions | Recommended products |
|---|---|---|
| Poor gas barrier | Water based oxygen barrier coatings | TAKELAC™ WPB |
| Tie layer for barrier resin and PP, which can design high barrier PP based film. | ADMER™ | |
| Low seal strength | Adjust heat seal strength and temperature range by using modifier | TAFMER™ |
| Narrow temperature gap |
