Efficient Form-Fill-Seal Machinery

Form-fill-seal units can often operate at web speeds as high as 600 inches per minute.

Forming, filling, and sealing all at one station is one of the most efficient ways to package drugs and devices. But FFS machines aren't for everyone.

Device makers that produce low volumes of several different product lines don't need such a high-speed packaging line. But for companies that have the volume, these machines, with their easy-to-clean frames and quick-changeover parts, make a packaging engineer's job a lot easier.

A horizontal form-fill-seal machine features a top-opening, adjustable forming box and repeatable settings, allowing for quick changeover. Individually adjustable film spindles and tilting fin sealers provide enhanced control of the film for tighter packages. The FW-3400 Alpha V's control system performs on-line production reporting. Formost Packaging Machines Inc., Woodinville, WA.

A thermoform-fill-seal machine allows users to fully validate sealing dwell time, temperature, and pressure. The MT2500's design allows web widths from 8 to 21 in. to be changed on-line. Able to draw down to depths of 5 in., it can operate at web speeds up to 600 in./min. Doyen Medipharm Inc., Morris Plains, NJ.

A vertical form-fill-seal machine can produce pouches sealed on four sides in multiples ranging from 2 to 12 across the die face. Model RVF-16.5S features dual-axis, servo-driven, rotary heat sealing dies that can operate intermittently or continuously. Pouch sizes can range from 0.5 to 16.5 in. wide in almost any length. The machine can accommodate a variety of thermoplastic, laminate, and coextruded films. Prodo-Pak Corp., Garfield, NJ.

A vertical form-fill-seal machine features wash-down servomotors, an off-the-shelf controller and touch-screen operator interface, reverse-strip sealing jaws, and a polyethylene-friendly extended-stroke back platen. The system can store up to 100 user-defined programs and provides temperature-controlled sealing system heat zones. Hayssen, a Barry-Wehmiller Co., Duncan, SC.

A vertical form-fill-seal machine can produce up to 60 bags per minute with lengths up to 15.5 in. The Vertek has a small footprint and a table that pivots to drop sealed bags onto a pickup conveyor. Operating parameters are stored in memory and shown on an LCD. Temperature, film length, film registration cutoff, dwell time, and belt speed can be recalled instantly. The stationary-width seal jaws use individual thermocouples for constant temperature control. Paxiom/WeighPack, Lachine, PQ, Canada.

An intermittent-motion vertical form-fill-seal unit can fill sachets and pouches with powders, granulates, tablets, liquids, and creams at speeds up to 70 strokes per minute. The MS235 can also transfer and count pouches into predefined stacks and cartons. A microprocessor monitors operations, a swiveling eye-level control panel displays functions, and a pneumatic system ensures optimum pressure and a tight seal. Marchesini Packaging Machinery, West Caldwell, NJ.

A compact rollstock forming machine is designed for medium output requirements. The R330 is constructed of easy-to-clean, high-grade stainless steel and features a hermetically sealed control-panel keyboard, enabling the machine to be washed and hosed down. Two complete die sets can be mounted on the machine. Multivac, St. Louis, MO.

A horizontal form-fill-seal machine can package both high- and low-profile products. The system allows users to control the packaging material without using vacuum openers or transfers. Once the pouch is made, it is transferred, positively opened, loaded, and closed without wrinkled final seals. Action Packaging Automation Inc., Roosevelt, NJ.

A semiautomatic mobile blister packaging machine is designed for laboratory use or small-batch production. The EZ blister is suitable for R&D, clinical trials, and stability studies. Sepha Products, Irvine, CA.
