AI Technical Summary
There is a need for polymer compositions suitable for high-frequency welding that avoid chlorinated materials, allow for direct processing, and exhibit good seal strength and printability, while being able to form into various structures such as films, sheets, foams, profiles, fibers, or molded articles.
A cross-linkable polyethylene composition comprising a copolymer of ethylene and an α-olefin comonomer with a specific density range, combined with a terpolymer of ethylene, a polar comonomer, and a cross-linkable comonomer, where the polar comonomer is present in a specific weight percentage, enabling high-frequency welding without the need for additional materials or helper layers.
The composition achieves fast sealing times and high seal strengths, maintaining good mechanical properties and printability, with the ability to be processed into various forms suitable for high-frequency welding applications.
