Impulse Pedal Sealer
FRS-400JT Foot-Operated Sealing Machine
A simple machine done well. The FRS-400JT uses electrical pulse heating to finish a seal in 0.2 to 2 seconds instead of the 2 to 4 seconds older machines needed, with heat time adjustable to the film. It weighs about 10 kg, runs from a single-phase supply, and seals the plastic film bags used across food, retail, electrical and service trades.

Overview
The Case for a Simple Pedal Sealer
Not every packing room needs a conveyor machine. For short runs, mixed bag sizes and awkward shapes, a foot-operated impulse sealer is faster because the operator never waits for a belt and never has to steer a bag. The FRS-400JT is aimed squarely at that job.
- Fast pulseElectrical pulse heating cuts the working time from 2–4 seconds to 0.2–2 seconds, so cycles follow the operator's pace.
- Adjustable heat timeOne dial covers thin pouches and heavier film, so the machine is not tied to a single bag type.
- Ready on power-upThe element heats on demand, so there is no warm-up before the first bag or idle heat between bags.
- Low running costWith only the element and the cloth as wear parts, upkeep is simple and inexpensive.
Operating Routine
Four Steps, Learned in Minutes
There is almost nothing to configure, which is what makes this class of machine so quick to put to work.
01
Place
Lay the bag mouth across the sealing bar with both hands and align it to the guides.
02
Pedal
Press the foot pedal to close the jaw and start the heating pulse.
03
Seal
The element melts the film for the set time, between 0.2 and 2 seconds depending on the film.
04
Release
Release the pedal, let the seal set, and move the finished bag aside for the next one.
Pulse Timing
Why 0.2 Seconds Beats 4 Seconds
The difference between a conventional heated bar and impulse technology is not the temperature reached, but how long the film is exposed to it.
| Aspect | Conventional Heated Bar | FRS-400JT Pulse |
|---|---|---|
| Heating time | 2–4 seconds | 0.2–2 seconds |
| Warm-up | Waits for the bar to reach temperature | Element heats on demand |
| Thin film | Risk of scorching and shrinkage | Short pulse protects thin gauges |
| Thick film | Needs a long press, slowing the operator | Pulse time increased on the dial |
| Idle energy | Heat lost between every stroke | Current flows only during the stroke |
Pulse time is a starting setting, not a fixed value. Increase it for heavier film and reduce it for thin pouches, checking the seal by hand as you tune.

Advantages
Value That Shows Up in the Workday
The FRS-400JT is not complicated, and that is the point: less to set, less to maintain, less to go wrong.
Speed per Stroke
A 0.2 second pulse means the operator can move to the next bag almost immediately, which lifts real output.
One Dial, Many Films
Adjustable heat time covers the range of plastic films without a parts change.
Hands-Free Clamping
The foot pedal leaves both hands free to hold and position the bag, which speeds up soft and awkward packs.
Compact Footprint
At 720 × 380 mm and 10 kg, it fits a small bench and can be stored away when not in use.
Safe to Operate
Because the element only heats during the stroke, the jaws are not permanently hot and the burn risk is reduced.
Minimal Upkeep
Element, cloth and springs are the only wear items, and all are quick to replace.

FAQ
FRS-400JT Questions
Instead of keeping a hot bar pressed against the film for two to four seconds as older machines did, the pulse element reaches sealing temperature almost instantly and completes the cycle in 0.2 to 2 seconds. The operator gets a faster rhythm, the film spends less time under heat and the seal is more consistent.
Yes. Heating time is set on the machine, so the same sealer can close a thin pouch with a short pulse and a heavier film with a longer one. That adjustability is what lets a single pedal sealer cover a wide range of gauges without changing the element.
It seals the plastic film bags used across food, local produce, electrical components, retail and service trades. It is a general-purpose impulse sealer rather than a specialist machine, which is exactly why it is found in so many small packing rooms and workshops.
The datasheet rating is 10 cycles per minute, which is set by the pulse time plus the operator moving the bag. In practice the pace depends on bag size and how the work is laid out, but the short pulse keeps the machine ready for the next bag almost immediately.
The machine weighs about 10 kg and measures 720 x 380 x 215 mm, so one person can lift it onto a bench or move it between packing stations. It needs only a single-phase supply and a working surface, which is why it is a common first sealing machine.
It is assembled and tested before dispatch and ships in double-layer packing. Standard production is about 5 working days with express transit of roughly 4 to 6 working days. Heating elements, high-temperature cloth and springs are supplied as consumables, and a 2-year warranty applies.
