Food Packaging: Cost-Cutting Materials and Fitments
Reclosable retort pouch for seafood makes U.S. debutFish and seafood packaged in retort pouches have been on the market for some time. However, none of these pouches were resealable, because of the difficulty developing a reclosable zipper that could withstand the extreme temperatures of the retort process. Now that challenge has been overcome by Pyramid Flexible Packaging, in alliance with zipper producer Presto Products, which has developed a reclosable retort pouch for Blue Star Food Products' six varieties of crabmeat.
The four-ply foil retort laminate pouch is produced at Pyramid's converting facility in Korea. Currently, the packages for Blue Star's crabmeat products have a 12-month refrigerated shelf life. According to Dean Hoss, president, Pyramid Flexible Packaging, the heat-resistant Zip'n Store retort package can also be used in the microwave and as a boil-in bag for cooking and reheating food products inside the package.
The reclosable retort pouches are available in a three-side seal, stand-up, die-cut handle, and contoured shape pre-made pouch format.
Presto Products' new Fresh-Lock reclosable retort zippers are composed of retort-grade cast polypropylene and are designed for retort and other high-temperature packaging applications. According to Presto, new equipment is not required to use the zippers because they are easily incorporated into form-fill-seal equipment currently being used for zipper applications.
The new resealable retort pouch provides numerous advantages to Blue Star. "This technology lets us capitalize on our product being closer to fresh-picked crabmeat versus the old industry standard-canned pasteurized crabmeat," says Steve Harmell, senior vice president of marketing and sales at Blue Star.
Blue Star developed its own pasteurizing process which uses lower temperatures and less retort time to help produce fresher tasting crabmeat in a pouch. "There have been frozen seafood packers using pouches for a while," notes Harmell. "There are canned tuna companies now using the same technology, but for a ‘sterilized' product, not pasteurized. We were the first-and the first with a resealable package."
While the convenience of a reclosable pouch appeals to consumers, Harmell points out that the advantages of using pouch packaging versus traditional glass or metal containers for its seafood are mainly to do with taste, including what he says is a better taste in the pouch, versus the "tinny flavor" from pasteurizing in cans.

Uncorked innovation pops in the wine industryCanandaigua, NY-based Canandaigua Wine Company has taken grab and go convenience to a new level with its Almaden Red Sangria in Tetra Pak's 500ml Tetra Prisma Aseptic package. This is the first wine product packaged in Tetra Pak's octagonal-shaped Tetra Prisma.
The Tetra Prisma Aseptic is a conveniently-sized, portable container with an easy-open pull-tab. The carton features a seven-layer lamination; stiff paperboard provides strength, shape and graphic surface, while an ultra-thin layer of aluminum provides a protective barrier against light and oxygen. Polyethylene forms the innermost layer, providing a liquid-tight seal to protect the wine, and an outer layer protects the package from external elements such as moisture.
After extensive shelf life and consumer testing as well as package integrity trials, Canandaigua realized that consumers wanted more options than the traditional glass wine bottle. The company also realized that Tetra Prisma's ease of handling and shatterproof attributes would cater to a broader range of wine-lovers with fast-paced, active lifestyles.
The lightweight aseptic carton also differentiates the brand on the shelf and makes the wine economical to distribute, store and stock.

Cost-efficient clear barrier OPP films introducedToray Plastics (America), Inc., a producer of clear and metallized polypropylene and polyester packaging films, introduced a new line of Torayfan clear barrier polypropylene films designed to replace polyvinylidene chloride (PVdC)-coated films.
According to the company, the Torayfan CB-S films allow for a "substantial cost savings" over other heat-sealable, clear barrier films. "Depending upon the thickness chosen, [the CB-S films] can offer anywhere from a 10% to a 25% cost savings versus most PVdC-coated OPP products available in the market today," says Christopher Voght, product manager for the Torayfan division of Toray Plastics.
Applications for both the CB-S and CB-P films include the moisture transmission rate barrier web of multilayer laminations and a grease liner for packages requiring oil resistance.
According to Voght, the CB-S films are now in a scale-up with two major food companies in the snack food and bakery markets.

Cost-cutting multilayer barrier filmsA new line of multilayer barrier films produced by Greek company Flexopack S.A. provide the stiffness, transparency and thermal resistance needed in lidding and flow packs for fresh and processed meat, cheese and other foods.
Called FlexoHybar, the CO barrier film uses Ticona's Topas cyclic olefin copolymer (COC) layer to gain transparency and improve moisture barrier. This layer eliminates the need to build stiffness by laminating oriented films to the barrier-coextruded film, which reduces production steps and helps reduce costs.
The new Flexopack films have up to nine layers and control the permeation of moisture, oxygen, and odors. According to Ticona, the Topas COC layer in these films also provides excellent abuse and puncture resistance, which is important to the performance of lidding and flow pack films.
"By combining barrier and stiffness in our structure, we make FlexoHybar CO films in a single, coextruded operation rather than in two or three processing steps," says Stamatis Ginosatis, managing director of Flexopack. "The result is a film having excellent economics for use in surface-printed and unprinted lidding for thermoformed rigid or semi-rigid combinations in modified atmosphere packaging."
Flexopack's customer, Veropoulos S.A., a chain of supermarkets in Greece, is currently using the FlexoHybar films for some of its products.

Engineered to be consumer-friendly, especially for children and aging adults, the Dot Top can be used for a variety of products that are hot-filled, closed with mechanical vacuum or retorted with overriding pressure. To open the can, consumers peel back a small plastic dimple in the center of the lid. The vacuum that holds the lid in place is released and the lid lifts off the container. If the contents are not completely used, consumers can snap the lid back on and store it for later use. Hirzel Canning Companies and Farms is the first commercial food processor to launch Dot Top for its Dei Fratelli line of Presto pizza and dipping sauces.
