Libero vs Huggies pull-ups

I recently come across Libero diaper. Based on the packaging, the brand looks very similar to Huggies Drynite.

Are the two brands owned by the same company? And how are they different?

Nope, they are completely different companies. Huggies are an American diaper brand, made by Kimberly Clark, where Libero is a European diaper brand, made by Swedish company Essity. They both offer similar products (diapers and pants), but Libero does have a bit of a larger size range. Their diapers go up to 7 vs. Huggies 6, and their pants go up to a size 8.
