Sealed Air: Eco-friendly shrink films
Sealed Air’s next-generation line of micro-layered Cryovac Technology (CT) films, including Cryovac CT-300 Series, Cryovac CT-500 Series, and Cryovac CT-700 Series offer thinner gauge options than conventional polyolefin or polyvinyl chloride (PVC) overwraps, enabling users to reduce both their carbon footprint and overall operating costs.
The CT films accommodate applications that require thicker films, while maintaining a potential source reduction of up to 50% compared to traditional polyolefins, and up to 60% or more compared to PVC films, according to the company. The film’s reduced mass also allows it to shrink in given applications at lower tunnel temperatures, resulting in a solution that conserves energy and reduces overall carbon footprint throughout production and distribution.
CT shrink films are grouped and available in three distinct film families based on functionality and gauge. These categories include:
Cryovac CT-300 Series: Currently available in five gauges, the CT-300 series includes light-weight, performance-focused films that provide enhanced seal strength and durability. These general-purpose films are used in a wide variety of product applications.
Cryovac CT-500 Series: Currently available in four gauges, the CT-500 series offers a soft yet strong and tear-resistant alternative. CT-500 series films are most effective when used to wrap irregularly shaped products, as well as light-weight products better accommodated by softer films. The wide operating window of the 500 series accommodates a broad range of equipment including those in marginal operating condition.
Cryovac CT-700 Series: The CT-700 series is compatible with machines that can process up to 100 packs/min., and accommodates highly-automated packaging operations where speed is critical.
The new CT films all provide longer rolls than those typically found on conventional polyolefin and PVC materials, resulting in fewer changeovers and increased throughput. The CT films also provide improved clarity and optics to maximize presentation for retail.
