Welding structure
|
Heating tape
+ silicone pad
|
Electric heating tube + metal ironing knife
|
Instant heating and cooling, uniform pressure, high fit, direct heating without conduction loss, and no damage to the film structure.
|
Slow heating and cooling, uneven pressure, poor fit, large conduction loss, and damage to the film structure.
|
|
Welding times
|
1 time
|
2-3 times.
|
No damage to the film structure, increase speed and save time.
|
Repeated sealing and pressing will damage the film structure many times, and the heat sealing time takes a large proportion and the speed is very slow.
|
|
Warm up time
|
150℃/0.85S
|
Preheat for 28-30 minutes, and uninterrupted heating.
|
Save electricity by 67%. Warm-up time shortened by 99%.
|
Power consumption is large, increasing product cost. The warm-up wait time is long.
|
|
Cooling
|
50-70℃/1S (heat sealing and cooling as a whole)
|
Continuously energized and heated, unable to cool down.
|
It is more conducive to the heat sealing of PE bags and co-extruded film bags.
|
Unable to produce PE bags and co-extruded film bags.
|
|
Temperature difference between the middle and both ends in the welding knife
|
＜±2 ℃
|
＞25 ℃
|
The heat sealing is uniform and more reliable, the edges are neat and the quality is more guaranteed. The passing rate is 100%.
|
The temperature difference is large, the heating is uneven, and the heat sealing firmness is poor.
|
|
Material range
|
Composite film and PE, co-extruded film
|
Composite film
|
All films can be welded.
|
Adapt to limited materials
