New shrink film from Sealed Air makes produce packaging less foggy

The latest addition to Sealed Air's line of Cryovac Technology (CT) shrink films, CT-311 is reportedly the market's first micro-layered anti-fog shrink film, as well as its thinnest. Primarily used to package cold chain produce goods including mushrooms, corn and peppers, CT-311 film prevents water droplets (or fog) from accumulating inside of the film and clouding package contents.

The latest addition to Sealed Air's line of Cryovac Technology (CT) shrink films, CT-311 is reportedly the market's first micro-layered anti-fog shrink film, as well as its thinnest. Primarily used to package cold chain produce goods including mushrooms, corn and peppers, CT-311 film prevents water droplets (or fog) from accumulating inside of the film and clouding package contents.

Recent Sealed Air consumer testing found that protection and contamination prevention are among some of the most desired produce packaging priorities. Additionally, CT-311 shrink film accommodates growing demand for a microwaveable and thin-gauge anti-fog film, allowing consumers to heat products wrapped in this film directly in the package. CT-311 does not contain plasticizers that are typically used with PVC films.

"With the release of our new CT-311 shrink film, Sealed Air further demonstrates our commitment to continuous innovation," said Reid Kennedy, marketing director of shrink packaging solutions for Sealed Air's product care division. "CT-311's combination of excellent optics, increased performance and microwave compatibility delivers the most complete shrink material available for fresh produce, all while enabling packagers to reduce their material usage."

Compared with standard 60-gauge PVC film, CT-311 shrink film enables packagers to reduce their material usage by up to 20% and material weight by up to 67% (for an 8 oz. package). In partnership with the Sustainable Packaging Coalition and its How2Recycle program, CT-311 shrink film (#4) qualifies for the new local store drop-off category and can be collected at numerous nationwide locations.

According to a third-party verified life cycle analysis, CT-311 has a 64% lower carbon footprint and a 64% lower cumulative energy demand than 60-gauge PVC.

"CT-311 shrink film is the latest technology to exemplify our SmartLife approach to sustainable packaging, which emphasizes efficient protection through innovative materials that reduce cost and overall environmental footprint for users," said Kennedy. "We've received excellent feedback from internal consumer testing and industry analysis thus far, with a significant audience expressing preference for CT-311 shrink film when compared with PVC overwrap. We look forward to delivering these shrink benefits to a wider marketplace."
