IN Brief:
- Cryovac is marking 85 years since the trademark was registered in 1941.
- Its portfolio now spans shrink bags, vacuum skin packs, films, vertical systems, and rotary vacuum chamber equipment.
- Food manufacturers increasingly need packaging materials and machinery engineered as a single production system.
Cryovac is marking 85 years since the trademark was registered in 1941, with its development reflecting the growing integration of barrier materials, packaging machinery, automation, technical service, and food preservation.
The name originated from an early process in which food was vacuum sealed before exposure to cold air caused the package to shrink around the product. That approach established a model in which the packaging material and the operating process were engineered together.
Cryovac’s current portfolio spans shrink bags, vacuum skin packaging, rollstock films, vertical form fill and seal systems, and rotary vacuum chamber equipment. More than 4,000 rotary chamber systems have been installed across meat, poultry, cheese, seafood, and prepared food applications.
The business also maintains an extensive technical service operation, with employees carrying an average tenure of approximately 11 years. Long-term application knowledge becomes especially valuable where a packaging fault can affect throughput, seal integrity, shelf life, and food waste simultaneously.
Cryovac forms part of Sealed Air, which reported sales of around $5.4 billion in 2024 and operates across 117 countries with approximately 16,400 employees. The scale of the business reflects the extent to which food packaging has moved beyond a standalone film purchase.
Materials, machine settings, product properties, environmental conditions, and maintenance routines now interact closely enough that a change in one area can disrupt the whole line. Packaging performance increasingly depends on suppliers being able to support both the material and the process that converts it.
Regulation accelerates material conversion
European packaging regulation is increasing demand for recyclable structures and lower material use, although changing a film rarely amounts to a direct substitution. Seal temperature, dwell time, tension, puncture resistance, oxygen transmission, clarity, shrink response, and machinability all influence whether a revised structure performs at production speed.
A material that succeeds during laboratory testing can still reduce throughput or increase rejects when introduced to an existing line. Wrinkles, weak seals, contamination in the sealing area, poor evacuation, and inconsistent cutting can quickly offset the material reduction through wasted food and packaging.
Validation therefore needs to cover equipment settings, product variation, sanitation, storage, distribution, and operator practice. Recyclability alone cannot compensate for a pack that fails to protect the food or repeatedly interrupts production.
Connected machinery is adding more data to that process. Multivac’s connected packaging platform, for example, links equipment and control information across the line, allowing factories to detect drift and maintenance requirements before faults become visible in finished packs.
Vacuum and high-barrier formats remain central to meat and cheese production because they limit oxygen exposure, moisture loss, and microbial deterioration. Reducing material while preserving those functions prevents environmental gains in packaging from being outweighed by food waste, returns, and shortened shelf life.
Alternative structures continue to develop alongside recyclable plastics. VTT’s cellulose film platform illustrates the range of materials being assessed for barrier applications, although each must satisfy the same industrial requirements around sealing, moisture, grease, line speed, and mechanical protection.
Technical service will become more important as conversions accelerate. A plant switching material may need revised forming sets, sealing profiles, software recipes, maintenance intervals, or operator training, while faults can originate in the product, film, machine, environment, or interaction between them.
Accurate diagnosis determines whether a conversion proceeds smoothly or produces months of intermittent rejects. Suppliers able to combine materials expertise with process engineering are consequently better placed than businesses offering a nominally compliant structure without detailed support on the line.
Cryovac’s anniversary underlines an engineering principle that has endured through several generations of packaging technology. Food packs operate as production systems, and successful material reduction will continue to depend on the interaction between the package, machinery, product, and technical teams responsible for holding every variable within specification.
