Performance Features   

1.  Two series derivate from FR-1120 series: one is FRM-1120 series, among this series, both 

vertical sealer and horizontal sealer are equipped with solid-ink roller coding mechanism, 
further, model FRS-1120W can also choose to be equipped with color ribbon printing 
mechanism. The other is FR-1370 series, all of which belong to vertical sealer with two sets of 
heating blocks, suit for sealing thick plastic bags.   

The instructions concerning printing mechanism has nothing to do with the sealer without 
printing mechanism. And model FRM-1370AL/M is a customized order, which is equipped 
with two heating blocks and solid coding mechanism. 

2 This sealer, adopting electronic thermostat control unit and stepless speed-adjusting 

transmission mechanism (Transmission speed of FR-1370AL/M and FR-1370AL/L is 
unadjustable), can seal various plastic film bags in different materials and can also be 
equipped with varied packaging production lines. The machine has no limitation on sealing 
length, which is characterized by high efficiency in continuous sealing, reliable sealing quality, 
rational structure and convenient operation etc. 

3. FRM-1120 series can use solid-ink roller to print desired colored label while sealing, with the 

characteristics of high definition, instant print and instant dry and strong adhesion; For letters 
in R type arrange, the machine can print two lines in font size two (18PT) and three lines in 
font size five (10.5PT), and 20 types can be arranged in each line. Special order for T arrange 
or multi-line types is available.

Structure & Working principle 

1.This machine is made up of rack, speed-adjusting mechanism, sealing temperature 

control system, transmission and conveying system, and printing assembly etc..(see 
diagram 1~diagram 8) 

2.After the power supply being connected, electrothermal elements produce heat that 

rapidly raise the temperature of both upper and lower heat blocks. And use the 
temperature controller and speed-adjusting mechanism to adjust the temperature that 
needed, the plastic packing bag is transmitted by conveyor belt, and its sealing part will 
be conveyed into the middle of two working sealing belts, then it is clamped by the two 
sealing belt and conveyed into the heating area, sealing part is pressed by two heating 
blocks and impressing wheels there, which could make the plastic film fuse and stick 
together. After this, the sealing part will be conveyed into the cooling area for cooling, 
and then to be pressed by embossing wheel for making stripe or netted pattern, at last, 
colored label on the sealing part will be coded by printing wheel. 

3.The transmission of sealing and printing is started by motor, which drives sealing belts, 

guiding belts and conveyor belt to work synchronously, as well as make printing
