Rigid Packaging

Cost competitiveness and efficiency are two key drivers for rigid packaging applications. Material solutions should enable high line speeds with excellent processability whilst reducing material consumption through thin film coatings thereby supporting both sustainability and cost competitiveness. For applications such as food cartons, trays and sleeves, specific functional coating characteristics such as excellent sealing properties, resistance to grease, abrasion and heat are essential. Other specialty applications such as photo paper require smooth, flat surfaces and good printability. Finally, improving sustainability is an industry-wide trend aimed at offering more environmentally-friendly board and paper coatings.

Our technology supports a broad range of low density polyethylene (LDPE), high density polyethylene (HDPE) and polypropylene-based (PP) applications in the manufacture of extrusion coating products.

CT7200: our patented technological breakthrough

An LDPE produced on a high-pressure tubular reactor, CT7200 is a Borealis solution developed for extrusion coating products that will help the industry address the issue of the pending closure of autoclave plants. Our new high pressure tubular platform enables us to secure supply for the global extrusion coating market in full compliance with all applicable regulatory requirements. CT7200 shares the high-quality organoleptics of currently available materials yet has numerous other advantages:

• High zero shear viscosity contributes to improved sealing performance
• Improved flowability enhances the adhesion to various substrates, even at lower processing temperatures
• Reduced energy consumption (motor load) at the same output rates results in improved sustainability
• Good optical properties
• Low gel levels

CT7200 is ideally suited for applications involving high-volume extrusion coating of boards and papers, liquid packaging, extrusion coating and lamination of different substrates and co-extrusion in multi-structures.

A complete range of HDPE and PP products

Our HDPE grades offer the following property improvements compared to LDPE:

• Reduced water vapour transfer rate (WVTR)
• Temperature resistance
• Lowered coefficient of friction (COF)
• Stiffness
• Abrasion resistance
• Grease resistance
• Source reduction

Our specialty PP grades feature:

• High stiffness
• Barrier to moisture vapour transmission and grease permeability
• Clarity and surface gloss
• Heat resistance
• Tensile strength
