Procter packaging and bag

The Procter & Gamble Co., Cincinnati, has submitted a patent with a much better, much more sustainable method for saving package and film costs other than to minimize film caliper. The trick is try using a foamed film produced in part or whole with or, renewable and recyclable biodegradable components.

The patent filing published per month earlier highlights the substantial usage of polyolefin (i.epolyethylene, polypropylene, . and polyethylene terephthalate) being a family of dependable packaging polymers that provide strength, product and clarity defense for bags, wraps, pouches and labels. Downgauging of polyolefin substrates to reduce material and costs might be difficult in possibly weakening the package structure to a point that may affect needed characteristics like a straightforward-tear launching as well as other efficient elements.

P&G’s offered orbital stretch wrapper solution is to utilize a film produced from a replenishable polymer that can be foamed as being a thin covering with gaseous bubbles or tissues. According to the patent, the foamed thin packaging film includes a bio-based content of between about 10% and 100%, a caliper of between 10 and 250 microns, and a density reduction of between 5% to 50% compared to non-foamed film of about the same caliper.

When foamed polymers are nothing at all new, concentrating on a green material in this way gives a new challenge to the orbital stretch wrapper packaging table that’s a far healthier substitute to the atmosphere.
