■ Overview of the L Series

The temperature-controlled L Series is an electric large sealer designed for large bags, capable of sealing from 60 cm to 1.2 m.
After setting the heating and cooling times according to the bag material, simply press the foot switch to create a strong, clean seal.
The angle and height of the sealer head are adjustable.
Various optional accessories and functions allow users to select only the features required to meet specific needs.

■ Standard Heating Temperature Control

Achieve Ideal Sealing Conditions

The key feature of ONPUL is its ability to set and maintain ideal sealing conditions. Temperature is monitored by a high-sensitivity sensor and controlled by a microprocessor, ensuring precise sealing at the film’s melting temperature, unaffected by ambient temperature or machine heat buildup.
Heating Temperature Setting Range: 90–250 °C
Cooling Temperature Setting Range: 60°C to the set sealing temperature*

* Cooling temperature must be set lower than the heating temperature.
Setting it too close may cause insufficient cooling and reduce the service life of components such as the fluoro glass sheet.

 

■ Up to 10 Operation Pattern Registrations

Register up to 10 settings with alphanumeric names.

 

■ Equipped with i-Heating Element

The i-heating element  , made from a low thermal expansion material, is used as the heat source.
By minimizing expansion during heating, it reduces stress on the heating element, lowering the risk of breakage and extending the service life of surrounding components, including temperature sensors.

 

■ Compatible with Various Packaging Materials

Seal Lengths: 600, 800, 1000, 1200 mm
Seal Widths: 5 mm or 10 mm
Two heating methods are available:

・ Single-Side Heating – Suitable for materials up to 0.3 mm total thickness (combined layers).

・ Double-Side Heating (Optional) – Suitable for thicker and laminated materials up to 0.4 mm total thickness.

The double-side heating model also accommodates heavy-duty and gusseted bags. When used with gas-barrier materials and oxygen absorbers, it helps extend product shelf life.

 

■ Adjustable Head Height

The head height can be electrically adjusted via buttons on the side of the control unit to accommodate various package contents.

・  Vertical head position: 830–1400 mm

・  Horizontal head position: 1030–1600 mm

 

 

See still images for each head height here. 

 

■ Adjustable Head Angle

The head angle can be steplessly adjusted from 0° to 90° via the adjustment handle to suit the product.
For powder packaging, tilting the sealer head downward helps prevent powder from spilling out of the bag during sealing.

■ Centralized Exhaust

Exhaust air from the drive compressor and vacuum pump is discharged outside the machine through a 5 m tube (ø12 mm).

 

■ Separate Air Compressor Required

A separate air compressor is required to operate the L series sealer.
Use a compatible air compressor with the following specifications:
0.75 kW  80 L/min 0.6 MPa or higher

 

Options

   

 

The L series offers various optional functions to meet diverse needs.
Customers can select only the required functions for their application.
Selected option codes are incorporated into the product name, which appears on the serial number label and allows you to confirm the installed options and specifications.

■ Tension Arm Option 3

L-1000T-10

Tension arms extend outward on both sides to hold the bag firmly stretched during sealing.
An evenly tensioned bag reduces wrinkles, improves the seal finish, and minimizes sealing failures.

■ Double-Side Heating Option 4

L-1000-10D

Ideal for thick bags and heavy-duty films.
Applies heat from both the upper and lower sides.

 

■ Braided Heating Element Option 5

L-1000-10DK

Stable Sealing for Powders

Simulation temperature control system is adopted to stabilize the performance of the braided heating element and reduce seal failures caused by powder interference in the sealing area.

 

 

■ IoT Function Option 8

L-1000-10-i

Early 2026 Release

Utilizing communication functions, the system enables remote monitoring and control of operating status, production management, and settings via a network connection.
