General

Heatsealing bands/wires are needed for sealing films/plastics and have a basic influence on the seam. Generally we differ in high- and low resistance heatsealing bands. Low resistance material is controlled with electronic temperature controllers in order to achieve short heating up times and a good repeatability of the sealing temperature. For an optimized functionality as well as for a low heat at the ends of the sealing bands the ends are enhanced by silver or copper.
arobatec offers the full range of ready-made heatsealing bands and wires as well as customized bands developed and manufactured for your application.Below a list of all popular heatsealing types:
Flatband
- For flat seams
- Low-Cost
- Higher mechanical pressure
at the edges of the seam
(Possibly problems with ZIP-Effect)
Tapered band
- Standard heatsealing band for flat seams
- With chamfered/tapered edges
(Thereby less mechanical pressure
at the edges of the seam)
Reflex band
- For flat seams
- Better seam quality with existing
film wrinkels/folds in the sealing area - Recommended when extremely tight
seams are required
(E.g. vacuum packed products)
Beaded band
- For Cut-and-Seal
- Good cutting with a normal wearout of
the PTFE antistick cover - Wider flat seam area/section accessible
T-Profile
- For Cut-and-Seal
- Very good cutting with a higher
wearout of the PTFE antistick cover
Cutting/round wire
Oval wire
Half round wire- For Cut-and-Seal
- Narrow seam
(depending on the band/wire version)
Contoured bands
Endless sealing bands
Customized versions- Production according customers request
