Secondary packaging (or overpackaging) can be both flexible and rigid, a monolayer or multilayer construction, or incorporate a peelable seal. It can also provide additional barrier or functional properties to the primary packaging. The potential for interaction between the secondary packaging and the primary packaging of healthcare applications has become a significant concern for producers. This has led to the need for enhanced purity and consistency of secondary packaging - right down to the packaging used during transport. LyondellBasell offers a variety of PE and PP grades suitable for secondary packaging, including our Purell LDPE and Purell PP grades.
