VILLINGENDORF, Germany, August 2007 – KORA-PACKMAT, a German company specializing in the manufacture of wrapping machines for low profile product packagng, will be exhibiting at Graph Expo 2007 in Chicago, IL. The highlight is the presentation of the new SonicSeal F, a machine for format flexible wrapping and ultrasonic-sealing of CDs, CD cards and software kits up to A5-size.
CD manufacturers can gain significant benefits from the ultrasonic-sealing of the wrapping of their CDs; ultrasonic seals provide tamper-evidence, intricate patterns on the seals increase protection against counterfeiting, and stiffness of the seals gives extra protection to the CD in a pack.
Material costs can be kept low as the wrapping sleeve is formed from single wound film spooled directly off a reel. Several wrapping designs are optional, e.g. a hanger pack including a re-closable flap. This pack is produced by first forming a header on the closed side of the folded film. Then the left and right hand sides of the pack are sealed with a security seal. A third security seal is placed at the bottom of the header to complete a three sided pack into which a CD is inserted. On the forth side, a strip of glue is deposited for the re-sealable flap before the flap is closed.
The seals of a pack are stiff and this gives extra protection to an optical disc inside the pack when the pack is handled during transport and in the retail shop.
SonicSeal F also has format-flexibility and can wrap CDs individually or as twin-packs. The accuracy and repeatability of the machine reduces trim waste to a minimum. A print registration system that enables optical discs to be wrapped with pre-printed film is an option, as is a Euro-slot punch for punching packs with headers.
