Sealer Sales HL-M1120LD-LtoR Vertical Band Sealer with Dry Ink Coding and Adjustable Sealing Head, 10mm Seal Width, Left Feed

The Sealer Sales HL-M1120LD is a heavy-duty vertical continuous band sealer with an adjustable sealing head, adjustable conveyor belt height, integrated dry-ink coding station, 10mm seal width, and 1/3 HP (230W) motor. The adjustable head and belt height together accept a wider range of filled bag sizes than the fixed-head M810II series. Sized for medium to heavy-duty production on liquid-filled or larger pack profiles.

Adjustable Sealing Head and Conveyor Belt Height

The sealing head and conveyor belt both adjust in height, which is the difference between this unit and the fixed-geometry M810II. A taller pack runs through with the head raised; a shorter pack runs through with the head lowered. The conveyor belt drops to give the operator clearance for awkward fills. This means one unit handles a wider product range without the operator having to swap fixtures.

Left-to-Right Feed Direction

The unit feeds left to right. The operator stands at the left side of the conveyor and finished bags exit on the right.

1/3 HP Motor for Heavy-Duty Production

The 1/3 HP (230W) motor is roughly 4.5x the power of the 50W motor on the M810 series. It is what makes this unit sustainable across multi-shift production runs with heavier filled bags. Sealing speed is 394 inches per minute, lower than the M810s but the unit is sized for heavier per-bag work rather than maximum bag count per minute.

Constant Direct-Heat Sealing with Cooling and Heating Blocks

The seal bars run on constant direct heat, with a pair each of cooling and heating blocks behind them. The heating block brings the bag film to seal temperature and the cooling block sets the seal before the bag exits the conveyor, so the operator is not pulling a hot, still-relaxing seal that distorts on the way out. The solid-state temperature controller holds the bars at the set point regardless of how many bags have passed through, which is what stops the intermittent-leaker problem that takes most band sealers out of spec by mid-shift.

Motorized Rubber Conveyor with Variable Speed Control

The conveyor is a motorized rubber belt with variable speed control, so the operator can dial in the dwell time for the film gauge and bag profile being run. Knurled pressure rolls above the conveyor adjust independently so a heavy filled bag gets enough pressure on the seal bars while a light empty bag does not get crushed. The whole conveyor is fully adjustable, meaning both height and depth relative to the seal bars, so the operator can center the seal on any bag size from small portion packs up to the maximum bag the configuration handles.

Dry-Ink Coding Station on the Seal Line

An integrated dry-ink coding station prints lot or date code directly onto the seal line as the bag passes through. The typeset is changed by swapping the printing wheel, so the operator can switch codes for a new run without re-tooling. Common configurations use 18PT type for product code, expiration date, or batch lot. The ink reservoir holds enough ink for thousands of cycles before refill, and the print head can be disabled if the operator does not want coding on a particular run.

Stainless Steel Construction with Field-Service Spare Parts

The housing and major chassis components are stainless steel, which holds up to wipe-down cleaning, ambient moisture in food and beverage production rooms, and the day-in day-out vibration of continuous-band operation. The manufacturer ships a spare parts kit with every unit including PC board, PTFE belt, wheel belt, fuses, motor brush, heating element, silica gel ring, silicone pin, and tools. Most operators keep one PTFE belt and one wheel belt in a drawer next to the sealer because those are the wear items that turn over fastest.
