Texwrap side seal wrappers use Texwrap’s exclusive new Versa Seal to insure consistent, high quality seals across a wide range of film types and gauges. The TVS is a very simple device yet offers outstanding control of the three elements necessary for a good seal- time, temperature and pressure.

Typically, on a side seal wrapper, the side seal mechanism itself is the single highest maintenance item on the machine. This technology is a revolution in simplicity and reliability. The Versa Seal requires no air and has very few moving parts for ease of operation and minimal maintenance.

Here's how it works. As film enters the sealing area, it is tightly clamped between pairs of top and bottom belts while a special heating element seals and separates the film between them. The design of the uncoated element avoids wear, film buildup, and the need for adjustment or repositioning to maintain a good seal. The TVS is a "self-compensating" system which means that there is no need for the operator to adjust temperature with line speed changes.

During sealing, the slightly diverging belts grip the film securely over a long distance allowing the seal to be made and the trim to be cleanly separated. Because the film gripping belts on the TVS allow the tension on the film to be isolated from the sealing process, the result is consistent seals using the absolute minimum film width.

    Maintenance >

     Very few moving parts, no air and an uncoated sealing element to avoid wear and replacement mean that the TVS seals consistently with very little maintenance

    The position, angle, and length of the sealing element allow the film to seal directly on the element for the most positive seal possible

    Compensating >

    No need to make temperature adjustments as speed changes. As speed increases, the film simply stays in contact with the element longer

    Trim Separation >

    Top and bottom belts clamp the film between them. The belts also diverge slightly along the sealing path to separate the trim for fewer scrap breaks and restarts

    Saves Film >

    The Versa Seal  grips the film tightly between the belts as it is being sealed. This isolates film tension from the sealing process resulting in a narrower film required

    Film Control >

    The parallel belts grip and hold the film thru the sealing area for total control of the film while it is being sealed for maximum uptime and fewer reworks

    Powered Rollers >

    Powered nip rollers pull the incoming film and feed it into the TVS film gripping belts. This insures no film slippage and and prolongs belt life

    Construction >

    As one of the most critical parts of the machine in terms of reliability, the TVS system is built to the same rugged standards as all Texwrap equipment

    Should something other than film enter, a switch on the nip rollers will detect it and shut the system down
