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
