1 Product Introduction
1.1 Products’ application
This sealer is suitable for sealing all kinds of plastic films, which is widely used in fields of food, medicine,
chemicals, commodities and agriculture, etc. It is ideal sealing equipment for packing batch products in
factories and shops.
1.2 Products’ feature
This sealer is ideal for sealing small packages, which adopts constant temperature control system
and stepless speed adjusting transmission mechanism.
It has the advantages of high efficiency for continuous sealing, reliable sealing quality, superior
structure and simple operation, etc.
The sealing direction of standard machine is from right to left. It can also be designed to seal from
left to right according to customers’ requirement.
It has three types: horizontal type, vertical type and floor type. The horizontal type one is suitable
for sealing packs of dry products while vertical one for powder or liquid products.
After sealing, the pack has grid embossing or stripe embossing. Also blank smooth embossing is
optional. Additional embossing roller or counter can be provided according to the customers’
requirements.
The machine works with solid-ink coder to print the colored labels while sealing. The coder is able to
print highly legible letters in optional colors. And it can dry instantly with good adhesion property.
The machine can print two lines in font size four (18PT) or three lines in font size five (10.5PT) at the
same time in R arrange. Every line can arrange 20 characters. And the company can provide
customers with special orders for T-type arrangements and multiple lines.
It applies to sealing different plastic films made from various materials. Or it can also be customized
to match with different packing lines.
1.3 Operation principles
After power supply is connected, electrothermal elements start to produce heat, which leads to rapid
temperature rise of both upper and bottom heating blocks. Adjust temperature controller and
speed-adjusting knob to get the required temperature and speed respectively. The sealing area of plastic
packing bag is conveyed to the position between two sealing belts by conveyor belt first, then clamped by
two sealing belts and delivered to the heating area. The plastic film is heated and softened. Under the
pressure from pinch roller, the film binds. After this, the sealing part will be conveyed to the cooling area
for cooling and forming, and then pressed by embossing roller for making stripe or grid pattern, and print
the needed colored labels.
The running of transmission part of the sealer and printer is started by motor, which drives sealing belts,
guiding belts and conveyor belt through gears to run synchronously, and intermittently drive the printing
mechanism to work synchronously.
