UK-based chemical company LyondellBasell has partnered with German chemical and consumer goods supplier Henkel to develop reopen/reclose properties for re-closable packaging.

Henkel created a hotmelt adhesive based on LyondellBasell ’s plastomer technology, which is claimed to offer improved reopen/reclose properties.

The final hotmelt adhesive is produced by Henkel and offers required reopening and reclosure capabilities on amorphous polyethylene terephthalate (APET) and polyolefin trays even after multiple uses.

Henkel said the new solution offers more advantages than any previously used technologies.

Henkel Europe product development packaging adhesives head Dirk Kasper said: “It’s the first time we are using this type of solution for re-closable packaging.

“Thanks to its product design, our re-closable hotmelt provides processing advantages compared with current market alternatives.

“This is about its very good compatibility with coextruded materials such as polyethylene (PE) or polyethylene terephthalate glycol (PET-G) and stable film-blowing.

“Additionally, it shows long-lasting reclosability properties.”

LyondellBasell said the re-closable packaging is easy to use and keeps food fresh for longer periods.

In addition, the technology minimises moisture gain and loss, microbiological development and taste deterioration in the food.

The packaging is currently available in Europe.

LyondellBasell technical service manager Stefano Pasquali said: “Besides the processing advantages, plastomers bring additional benefits to the end user.

“One characteristic that distinguishes our plastomer solution from traditionally used solutions is its low odour. This is especially important for food packaging.

“It is also one of the main ingredients, which allows it to make the packaging very easy to open and reclose, over and over again.

“We are proud that our solution contributes to an improved consumer experience while reducing food waste.”

In June this year, Henkel opened a hot-melt adhesive plant in Guadalupe, Mexico.

The facility will manufacture pressure-sensitive and non-pressure-sensitive hot melts under the company’s Technomelt brand.
