ExxonMobil Chemical (Baytown, Texas / USA; www.exxonmobil.com) has extended its range of “Exceed” metallocene polyethylene (mPE) resins through the introduction of a grade for extrusion coating and lamination applications. Exceed 0019XC, provides opportunities for innovation and value for converters and brand owners in a range of applications including drink cartons, lamitubes and flexible packaging, the company said.

When processed alone, or in a blend with autoclave LDPE, the material offers a combination of attributes that provide overall package sealing performance, the manufacturer said, and optimum sealing performance is achieved without compromising overall processability and extrusion, with a lower coefficient of friction than competitive grades. Sealing solutions provided by the material can optimise package integrity to help reduce package leakage and increase fill rates.

The company said that, through collaboration with converters, the material has been found to be effective when used in combination with a tie layer that offers adhesion to a base substrate, such as foil/ethylene acrylic acid (EAA) in drink cartons or lamitubes, to deliver a packaging solution. The grade also produces a tougher coating than LDPE, particularly on paper or raffia substrates.
