Fewer rejects with new freezer-to-microwave packaging

Apex 3739 MW is a multilayer coextruded film designed to withstand cold temperature bursts. “Effectively this is a polypropylene (PP) film that works like a polyethyl film,”​ the company’s innovation and marketing director, Sal Pellingra, told Food ProductionDaily.com.

“Its extreme cold and heat resistance mean there is a big reduction in package rejects and product loss during the distribution of frozen packaged goods,​” he said.

The technology has been designed to steam quick frozen foods such as vegetables, seafood, fish, breads and other foods, added Pellingra.

High seal strength​

The new film has a low seal initiation temperature, high seal strength, and improved slip properties, he added. Also, a broader sealing window is said to provide improved packaging speeds and efficiencies on vertical form fill seal machines.

Apex 3739, available in clear or opaque sealant film, provides an improved printing base for lamination to reverse printed polyethylene terephthalate (PET) or PP.

PureFlex MW packaging offers high quality printing either in flexo or rotogravure. The solventless lamination delivers an 86 per cent energy saving compared with similar solvent-based lamination qualifying for an energy innovation credit in the Walmart Scorecard system which recognizes green technologies.

All food types​

The film is available in one or two side sealable versions and is Food and Drug Administration (FDA) compliant for all food types.

Self-venting PureFlex requires no further ventilation during packaging or microwaving. “This helps to maintain the integrity of nutrients, food colour, taste and aroma by using microwave steam cooking technology​,” said Pellingra.

In addition to food packaging products, Ampac Flexibles supplies speciality shopping bags and security bag technology.
