Developments in packaging films

Packaging films are on a path of constant research and development (R&D) to enhance their key characteristics and improve suitability for use in a variety of applications. As such films take on the mantle of primary packaging, this ranges from their strength and preventing migration, to maximizing both shelf life and shelf appeal.

And for those producing such films, R&D is focused around a handful of ‘megatrends’, namely the environment and performance. A number of recent developments showcase this work, such as the launch of Propafilm RCU by Innovia Films. Propafilm RCU is a BOPP film that has been officially proven to provide up to 1.5 years protection from mineral oil migration, and was developed after research indicated foods were being contaminated by the migration of mineral oil from recycled paperboard.

KM Packaging Services has introduced KPeel 3G, a user-friendly lidding film designed to reduce instances of ‘wrap rage’. A survey by The Grocer in 2014 found that nine out of 10 British consumers are regularly gripped by ‘wrap rage’ – frustration with impenetrable or poorly functioning food packaging. KM Packaging says KPeel 3G will be ‘music to the ears of consumers who proactively seek out foodstuffs that are easier to open’.

KPeel 3G is a heatsealable polyester film which peels cleanly from trays in ambient or chilled conditions. Available in 21-, 25- and 40-micron thickness, KPeel 3G is suitable for printing using the flexo and gravure processes.

Additional features include macro hole and laser perforation. KPeel 3G films seal to CPet and APet trays and provide superior cold peel in one piece without shredding, even direct from the freezer, KM Packaging says. It is also suitable for microwave and conventional oven cooking, and chillable.

KM Packaging commercial director Graham Holding says: ‘[We are] constantly looking to innovate, not just for the sake of it, but to really seek out ways to make the consumer experience better and thus keep our customers – food manufacturers – happy.’

Amcor’s I-Peel is another heatsealable polyester lidding film which is said to answer consumer demand for packaging that is easy to open by hand with a smooth peel designed to minimize sharding.

Amcor says I-Peel delivers a consistent seal whether the packaging is heated or has come direct from the freezer, and is suitable for dual ovenability with all foodstuffs. It is available in 19, 26 and 40 microns. It is suitable for P-Plus – Amcor’s flagship tailored permeability films designed to maintain freshness and extend shelf life.

I-Peel is designed to stay sealed through the distribution chain ensuring the product arrives safely on shelf in stores, with the hermetic seal protecting food and preventing leaks. It can be sealed to aPET, rPET and cPET. Further, I-Peel’s high clarity coupled with anti-mist performance ensures the customer has a clear view of the product. I-Peel can be printed using Amcor Prism, Amcor Vivid technologies or conventionally.
