ILS Impulse Wire

L-Bar Sealers

Belco L-Sealers feature a welded tubular steel frame and sealing head design to maintain perfect alignment during the sealing process. This unique construction is superior to conventional assemblies that are simply bolted together.  This manufacturing process provides consistently strong seals, long machine life and years of trouble-free performance. 

Belco Impulse Wire sealing technology employs a single Nichrome wire to create the front seal and side seals around your package. During the Sealing Cycle, the wire temperature is controlled by the Seal Wire Heat Adjust for a fixed amount of time which is regulated by the Impulse Timer. A Sealing Wire Sensor monitors the heat buildup in the wire so overheating and wire breakage during the sealing cycle is prevented. For the larger sealers and custom sizes, individual Seal Wire Heat Adjust controls for the front seal and side seal are used. An Impulse/Constant Heat switch allows the operator to choose which sealing method is best for the particular film being sealed.

Belco L-Sealers come in a variety of sizes and styles to help you package your product in a quick and efficient manner.

 

All film manufacturers require sealing machines to control the same three variables in order to make their film seal: Time. Temperature and Pressure. For 60 years. Belco L-Sealers have easily met and surpassed these demands while producing fast. clean. and repeatable seals.

Features & Options

Popular Optional Configurations

Power Film Unwind


This motorized film cradle feeds film to the operator upon demand as the package is advanced into the seal area. Regardless of how fast the operator or how long or small the product size, this option can maximize production speeds while minimizing operator fatigue.




Adjustable Film Inverting Head


By Turning film inside out in a 90 degree manner, an in-line packaging operation can be created to significantly increase production flow, lessen product handling and increase operator efficiencies.




Hole Punches


Air evacuation devices allow excess air to escape the bag during the shrink process. Several styles are available to best fit your machine and application; Pin Wheel, Thermal, Air and Multi-Perforator




Custom Color


Belco can custom powder coat paint your machine to match your company colors or production floor requirements. Just supply your RAL paint specification along with your request for machine quote.




Magna-Lock Sealing Arm Systems


(For semi-automatic operation, choose either the Magna-Lock or Air-Operated Seal Arm with the optional Product Take-Away Conveyor.) Powerful magnets hold down the seal arm to provide semi-automatic operation and even seal pressure along the entire seal base. The adjustable timer provides the correct dwell time necessary to ensure consistent, strong, quality seals. This level of automation reduces operator fatigue while increasing production speeds.




Air-Operated Seal Arm


(For semi-automatic operation, choose either the Magna-Lock or Air-Operated Seal Arm with the optional Product Take-Away Conveyor.) This seal arm control system uses your facility’s air pressure to create repeatable, strong seals every cycle. Belco incorporates dual Opto-Touch (zero force) start switches which are ergonomically designed to eliminate hand, wrist and arm stress for your operator. The results are increased efficiencies and greater output at the end of each shift for your packaging operation.




Product Take-Away Conveyor


Once the seal is complete, the arm raises and the product is transferred out of the sealing area. An adjustable timer controls how long the conveyor moves the product, either all the way out of the seal area, or just far enough to make the next package.




Stainless Steel Construction


The Belco line-up of equipment is also offered in stainless steel construction for use in Pharmaceutical, Food, Meat, Fish and Poultry processing environments. They comply with FDA and USDA requirements for packaging your product. These are wipe-down rated machines and not designed for washdown cleaning.





How To Choose

Which Belco ILS is right for you?


Belco manufactures manual and semi-automatic L-bar heat sealers capable of running production speeds of 5 to 25 packages per minute. This represents 500,000 to 2,500,000 packages per year, based on an 8 hour day, single shift operation. The Impulse Models ILS 2016, ILS 2520, and ILS 3022 use a single nichrome element wire to create both the front and side seals. Set up is accomplished with the simple adjustment of the wire temperature and the impulse time controls. The Impulse Models ILS 4030, ILS 5030, ILS 5016, ILS 8442, and Custom sized sealers control the front and side seal wires independently with dedicated heat controls. In this way, wire temperature can be adjusted specifically for the package size. Hot Knife sealing technology is available on all Belco sealing equipment. This system uses cartridge heaters, thermocouples and Watlow digital temperature controllers to precisely monitor the side seal and front seal temperatures. Product changeovers and setups are exact and repeatable. Hot Knife inserts allow for simple maintenance and sealing of all shrink films.




Size


The first consideration is the size range of packages you need to wrap. Low profile packages can fit in seal areas that are much closer in size to your actual package length and width. Taller packages will require larger seal areas.
Seal capacities range from 20" Long x 16" Wide up to 84" Long x 42" Wide for our standard sealer line. Specific matching shrink tunnels are available to complete your shrink packaging system. Custom sized sealers and tunnels are available to meet your requirements.
Please feel free to contact your Belco sales representative or local distributor for a machine recommendation based on the maximum length, width and height of your product.




Shape


Do your packages include irregularly shaped designs? Will you be sealing multi-packs, high profile cube boxes or cartons? If so, you may want to consider Belco's optional features to enhance your system. Your operator will spend less time preparing and handling the product and you will realize more productivity.




Speed


Do you require medium or high speed productivity? You should consider how many packages you need to produce to meet peak demands as well as satisfy regular production schedules. Hot Knife sealing technology can dramatically increase your daily production output.




Options


Belco offers specific options that can be added to your ILS sealer to help meet production requirements and enhance productivity. Popular options include: powered film unwind, adjustable inverting head, air-operated seal arm, Magna-Lock hold down system and product take-away conveyor.




Maintenance


The Belco Impulse L-Sealers have two items to maintain: the seal base rubber and the Teflon protective strip. Both are reversible for long life and an operator can perform the change without the need for tools, parts or service technicians. Belco Hot Knife L-Sealers are built to be even more robust than our popular Impulse wire sealers. The machine operator only has one item to maintain: the seal base rubber. All other machine parts are designed for long life and require little attention. Belco machines are built to last so simple, preventative maintenance will ensure years of dependable performance.
