In our fast paced world of over scheduling and multi tasking, convenience is something we all want and have even come to expect. The simplicity of today's packaged products is a true benefit to our busy lives. For example, the juice pouch and stick of cheese have reinvented a child's lunch. The single serving coffee pouch in a hotel room minimizes the expense and wait for room service. Personal-size packages of wipes for wiping hands or surfaces allows easy and fast clean up anywhere.
These modern conveniences would not be possible with packaging equipment that employs seal bars. Companies within the packaging industry know that eye-catching graphics grab a consumer's attention but simple and convenient packages generate the sale.
An integral part of form-fill-seal and pouching equipment is the seal bar. Without precise and uniform heating, packaging machinery would not be as efficient or effective, and thus would not produce convenient, flexible packaging for the products today's consumer demands.
Most packaging applications require heaters that deliver quick ramp up times, temperature uniformity and precise temperature control to provide high-end speed and reliability. In today's competitive marketplace, companies are turning to Watlow and its experienced engineers for complete thermal loop solutions to maximize their packaging machinery's efficiency.
Year after year, customers depend on Watlow to solve tough sealing challenges. Watlow offers customization, global manufacturing and support as well as the ability to solve application problems with a variety of heater solutions.
The Watlow family of seal bar heaters provides flexibility and a variety of sizes to fit almost any thermal application. The superior sealing quality, cost-effectiveness and long service life of Watlow's seal bar heaters allow customers to enjoy advantages including increased production yields, greater throughput and bottom line efficiencies.
Thick Film Heaters
Watlow's thick film heaters can be customized to provide the precise control and temperature profile that demanding packaging applications require. Thick film heater circuitry provides even thermal output across the entire heater surface, helping to control and correct almost any temperature uniformity issue. These units are ideal for a multitude of seal bar applications because the heater can be designed to match any form desired – even integral to the seal bar, depending on the substrate. This versatility allows the heater to adapt to unique machine dimensions and geometries.
Low profile, low mass thick film heaters offer precise control, rapid start up and improved cycle times.
Thick film heaters are the ideal choice for seal bar heating because these heaters allow a continuously heated and thermally optimized seal bar, said Lori Morrison, marketing manager. The end result is a satisfactory release after sealing, which will enhance productivity and yields. Everyone wins!
FIREROD® Cartridge Heaters
FIREROD® heaters are an ideal solution for seal bar applications because FIREROD offers versatility for a broad range of packaging applications. These heaters provide superior heat transfer, uniform temperatures and resistance to oxidation and corrosion. FIREROD also offers wattage distribution along the heater length resulting in a uniform heat profile that is customized to the specific application.
To accommodate equipment with limited space outside the sealing bar, the FIREROD has very small no heat sections. The heater can be manufactured with internal thermocouples anywhere along the heater length to control application temperatures and offers the highest possible watt density for the fastest start up and recovery time.
The FIREROD was originally patented in 1954 and has been providing heating solutions for 50 years, said Morrison. It is a trusted name because it has been used successfully in over 250,000 different applications in multiple industries. It is reliable, accurate and can be custom designed. You can't go wrong with Watlow's FIREROD.
Cable Heaters
Cable heaters are a versatile seal bar solution and can be custom designed to fit seal bars and dies. The internal element wire for wattage distribution and internal thermocouple for sensing allows for optimal temperature control along the length of the blade. Accurate temperature control ensures process reliability and reduced downtime resulting in higher machine productivity.
The heater sheaths can be formed to fit many common blade/bar configurations.
The Watlow cable heater is long lasting and safe for the operator. It can also be formed into any shape desired, which makes it another trusted and reliable source for seal bar heating from Watlow, adds Morrison.
