Laser nicked lunch meat packaging

Pechiney has developed a technology called LaserTear, which is a linear laser nicking technology. Its advantages are convenience, safety, and reclosability. This nicking technology can create easy-open tear lines that can Fully meet the manufacturer's specifications. Hormel applied LaserTear technology to install a slide zipper on its Premium luncheon meat bag. This unique laser scoring method earned Pechiney a Silver Award for Technological Innovation.

Hormel's double-web horizontal thermoform/fill/seal bags can hold 8 ounces of product with a slide zipper mounted on a film with rectilinear laser scoring. This package uses five layers of coextruded film, including a nylon/adhesive/EVOH barrier/EVA seal layer. The zippered slide is a five-layer coextrusion product containing EVOH.

Pactiv`s Hefty and lide-Rite cuts cooked meat packs since last summer. This is said to be the first example of a zippered package using a horizontal machine. A large amount of R&D work on packaging design and overall closure technology has enabled the packaging bags to maintain the taste and freshness of cooked meat even after many openings have been closed. Pechiney pointed out that the LaserTear scoring technology can engrave directional lines, which can be linear or two-dimensional, with precise control of the depth of the nicks. Since the nicks are extremely light, almost no marks can be seen on the resulting finished package, but they can be accurately torn on this line, and the slide zipper can also be fully functional.

Dan Miller, Packaging Development Manager at Hormel Foods, pointed out: "We adopted this closure technology in the packaging of premium sliced ​​meat, not only brings us technical advantages, but also provides convenience to customers, and we have reason to believe that in the near future, In the future, this new type of zipper will become an industry standard.” This packaging product is the result of joint efforts: Hormel and Pechiney made efforts in the formation and sealing of the film; Pactiv provided the feed sealing system; equipment manufacturers developed SR-2002 horizontal forming/filling/sealing machine. Another model of the company's machines can be used for vacuum packaging of products and heat sealing of zippers.
