Equipment Focus: Packaging

Vacuum-packing capabilities answer demand for fresh, safe seafood attractively presented

September 01, 2006

Freshness is consumers' No. 1 concern when it comes to buying seafood (see SFB's Retail Survey, page 20). And packaging plays a key role 
in ensuring a safe and wholesome product, whether it's case-ready fillets or bulk packs of IQF shrimp. The packaging industry has developed high-tech processes and materials to extend shelf life with modified- and controlled-atmosphere packaging and shrink wraps that can be printed with colorful graphics to add visual appeal. Here's a sampling of state-of-the-art packaging options for fresh, 
frozen and prepared seafood.

Cryovac's case-ready

packs ensure freshness

The Cryovac Food Packaging Divi­sion of Sealed Air Corp., known for introducing Bubble Wrap® in 1960, has added case-ready options to its line of fresh fish packaging. Cryovac modified-atmosphere-pack­aging systems feature Avery Dennison TT Sensor™ time-temperature indicators to let retailers know if a product has experienced temperature abuse. Once activated, the TT Sensor™ changes color from yellow to pink at a pre-determined rate based on temperature 
exposure. To further enhance the 
appeal of MAP case-ready seafood, Sealed Air introduced Cryovac® Multi-Loc™ absorbent pads. Made of non-woven material on both sides, the pads provide an absorbent, slide-resistant solution for single fillets in the seafood case. They also absorb purge. Multi-Loc™ pads are available in black or white and in a range of custom sizes to fit the footprint of the tray. Cryovac's 10K OTR Darfresh® vacuum-skin package for fresh and frozen fish and shrimp meets Food and Drug Admin­is­tration oxygen-permeability standards and its skintight fit prevents 
surface dehydration and freezer burn. This enables processors and retailers to employ a freeze-and-slack-out 
option. The package is leak-resistant, prevents product purge and minimizes the risk of cross contamination. Darfresh® package allows an unobstructed view of the product before purchase and is ideal for marinated or pre-seasoned fish.

Rollstock vac-pack units

reliable, affordable

Rollstock offers low-priced, fully 
automatic machines for modified-
atmosphere and controlled-atmosphere packaging. MAP and CAP technology inhibits bacterial growth and oxidative rancidity by removing O2 and reduces weight loss from dehydration. Manufactured in the United States, Rollstock® vacuum packaging machines come in a variety of web widths, from 285 mm to 459 mm. They feature programmable PLC controls with readable diagnostics and a vacuum leak-check program. The guided chain system's automatic tensioning reduces stretch and wear. Dies are manufactured from solid-aluminum block and lifted by a triple-knee lever system, driven by a 4-inch air cylinder with variable height control. Included are training and a one-year or 1-million-cycle warranty. Available accessories include flying or guillotine cross-cut knife systems, hole punching, photo electric registration, code dating, auto labeling and gas flushing for CAP or MAP.

The RZ-200 Zipper Packaging Machine is designed for seafood products that require a reclosable package. A proven, simple zipper system developed by Pro-Pac Services is built into the Rollstock machine, making most parts interchangeable. At 18 feet, it is less than half the length of most zipper machines. Starting at $189,000, the RZ-200 is also about half the cost.
