New LDPE resin boosts flexible packaging performance

Lightweighting, improved strength and cost savings are all benefits for flexible packaging produced with a new LDPE resin, said LyondellBasell as it launched the product in North America.

The company said the Petrothene L3035 LDPE (low density polyethylene) resin can be used in a wide range of blown film applications. In comparison to competitive LDPE grades, the product “features high stiffness, shrink energy and puncture strength”. It also delivers a high standard of optics and visibility, said LyondellBasell.

Such properties make the new resin ideal for food and medical packaging, as well as collation shrink film and overwraps, said a company statement.

Lightweighting

The properties exhibited by Petrothene L3035 will allow packaging producers to downgauge their flexible packing – leading to material savings, it added.

“The puncture strength, high stiffness and shrink energy are of particular benefit to collation shrink film, contributing to a tighter, more robust package which enables the elimination of trays,” said Steve Imfeld, the company’s new business development manager for polyethylene flexible applications in the Americas.

The reduced material requirements offer potential cost savings to both converters and end-users, he said.

The new resin gives customers the opportunity to “produce very high quality film”. For collation shrink film, the tighter package helps maintain package integrity during transportation, while the enhanced visual appearance presents a more appealing consumer product on the store shelf, said LyondellBasell.
