Sealed Air spotlights Cryovac films for food packaging optimization

Sealed Air is highlighting its Cryovac Shrinkable Rollstock PrimeVac, designed for use with the Flow-Vac system on packaging lines to optimize food packaging processes. 

“Food processors continue to face pressures such as labor shortages, rising costs, and regulatory requirements, which are all influencing how production lines are managed,” says Sealed Air. “Packaging is becoming more closely linked to throughput, more efficient operations, and cost control.”

The food packaging giant adds that packaging choice is driven by factors such as material properties, barrier, and thickness, while the significance of the packaging process is often underestimated.

Processors are increasingly focusing on how packaging behaves on automated lines and its impact on stability, efficiency, and consistency at scale, Sealed Air says. The changing priorities drive interest in integrated approaches where materials and equipment are designed to work together.

“Cryovac Brand PrimeVac has been developed with this system-level performance in mind. It is a 40-micron, dust-free, permeable film with an EVOH barrier designed for creating in-line shrink bags on automatic packaging lines,” explains Sealed Air.

“When used as part of an integrated system combining film, Flow-Vac loading technology, and Cryovac vacuum chamber machines, the solution is designed to optimize overall line performance rather than individual components in isolation.”

The packaging technology company argues that Cryovac Brand PrimeVac can align film performance, loading technology, and vacuum chamber operation to support a stable throughput, consistent packaging quality, and efficient material usage in high-volume production environments.

Operation efficiency & material performance

Packaging systems that support stable operations can also help maintain throughput while reducing interruptions linked to start-stop events and manual intervention, according to Sealed Air. This is particularly significant at manufacturing sites with limited labor availability, where downtime is more costly.

Material efficiency is also growing in importance due to regulations, such as EPR, which link packaging use more directly to cost. The company says that for this reason, processors are looking for ways to reduce waste.

“When used within an automated system, this integrated approach is designed to support measurable improvements across operational efficiency, material performance, and sustainability compared to standard alternatives.”

Production hygiene is another key factor in line performance, according to Sealed Air. This is because materials that run without powders can support cleaner production conditions, helping to reduce cleaning requirements and minimize potential sources of contamination.

Combined with strong sealing performance and high barrier properties, powder-free production can contribute to consistent packaging integrity and food safety outcomes.

“The result is a more integrated view of packaging, where performance is measured by how effectively the system supports production across efficiency, material use, and pack integrity,” Sealed Air concludes.
