Packaging Resource Center: The Latest in Form-Fill-Seal
A company offers servo-sealing technology on its horizontal form-fill-seal machines. The technology involves applying pressure with a servo mechanical device instead of using pneumatic or hydraulic pressure. Mechanical pressure is applied in a closed-loop feedback system, which is designed to ensure that pressure is applied consistently. The closed-loop system also features confirmation of pressure application and pressure-sealing data storage. Alkar-RapidPak Inc., Lodi, WI; 608/592-3211; www.rapidpak.com.
An intermittent-motion machine is designed for forming, filling, and sealing bags at high speeds. The SVB 3601 can process up to 100 bags per minute. It is designed to produce gusset, stand-up, and zipper bags. It also can produce standard pillow pouches and bags with the manufacturer’s degassing valve. The machine can be configured to run heat-sealable and polyethylene packaging materials. It features vacuum-supported web draw-off. The system also features a microelectronic control system, touch screen, and microprocessor. Bosch Packaging Technology, Minneapolis, MN; 763/424-4700; www.boschpackaging.com.
A form-fill-seal machine is designed for handling products that require horizontal infeed into packages. The Flat-Pak is capable of running LDPE, LLDPE, PP, HDPE, and laminated materials. Single- and double-pouch systems are available. The single-pouch model produces up to 30 packages per minute, and the double-pouch model produces up to 60 per minute. The machine’s infeed system features a pusher and chute. It opens the bag before product delivery, and is designed to prevent the product from sticking to or cutting the pouch. The machine also accommodates loading of inserts, booklets, or desiccants. Action Packaging Automation Inc., Roosevelt, NJ; 609/448-9210; www.apaiusa.com.
Three- and four-side-seal pouches can be formed and filled at a rate of up to 240 pouches per minute. The Cosmo is an automatic horizontal pouching machine that also can produce stand-up pouches. No parts are needed for changing pouch sizes; changeover is achieved with simple adjustments. The machine can be equipped with feeding units for different kinds of product such as tablets, liquids, and powder. It can handle pouches from 40 × 40 mm to 90 × 160 mm.

A vertical form-fill-seal machine features dual-axis, servo-driven rotary-heating sealing dies. The RV-165 can operate in intermittent or continuous motion. It is designed to produce four-side-sealed pouches at rates from 100 to 1000 pouches per minute. It can be equipped to package liquids, tablets, or powders. Pouch-size adjustment is designed to be easy to complete using the servo control for the horizontal sealing die. The sealing technology is designed to be compatible with a variety of thermoplastic, laminate, and coextruded films. Prodo-Pak Corp., Garfield, NJ; 973/777-7770; www.prodo-pak.com.
A horizontal form-fill-seal machine produces four-sided packages with secure, sterile seals for products such as wound dressings, sterile field swab sticks, catheters, syringes, and sutures. The Integri-Seal features a seal-validation system, a color touch screen display that monitors speed, and single-point temperature and single-point pressure control during normal operation and at process setup. Single- and dual-lane configurations are available. Circle Packaging, De Pere, WI; 920/983-3420; www.circlepackaging.com.
