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 L-Sealers with Hot Knife Sealing Technology rely on a set of Mushroom Sealing Knives to seal the film at the proper temperature without creating fumes, smoke and residue common with Impulse Wire sealing machines. Traditional impulse wires operate at higher temperatures to seal and then cut the film while hot knife sealing uses a steel rule cutting blade to mechanically cut the film and the mushroom profile is used to create a small fin seal on the package. This system utilizes heavy duty cartridge heaters for long life, independent Watlow digital temperature controls and precision thermocouples to exactly monitor and control the side seal and front seal.
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.
Available Models
ILS2016HK ILS2520HK ILS3022HK ILS4030HK ILS5030HK ILS5016HK
The sealing operation is safe, fast and reliable. Simply place your product into the centerfold of film, advance both film and product into the seal area and lower the sealing arm. Upon completion of the heat seal cycle, the arm will return to the up position, leaving your product fully wrapped.

Popular Optional Configurations
Power Film Unwind
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.

Custom Color
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.)
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.)
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.
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 50" Long x 30" 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.
Features
Main Power Switch
Film Cradle
lnfeed Tray
Seal Arm Guards
Adjustable Tilt Table/Conveyor
Locking Casters and Leveling Pads
Welded Frame
Watlow Digital Temperature Controls
Independent digital controls monitor and adjust the heat to the front seal and the side seal.
Mushroom Seal Blades
Precise temperature control allows the film to be sealed without smoke or residue buildup. A small, strong fin seal is produced.
Radius Corner Cutoff
The hot knife sealing system operates at the film’s sealing temperature. A steel rule die blade mechanically cuts the film precisely and repeatedly. There are no corner alignment issues or a gap between the side seal and the front seal blades.
Seal Dwell Time Control
This adjustable time control monitors how long the seal knives are in contact with the film.
Options
Mechanical (Pin Wheel) Hole Punch

Foot Pedal Assist
This device is for heavy or awkward packages. Press the foot pedal to activate the product take-away conveyor and help move product from the infeed table into the seal area.
Product Take-Away Conveyor Time Delay
This option allows Polyethylene seals to "set" before the Product Take-Away Conveyor moves the package out of the seal area. Always recommended for Polyethylene sealing.
