Heatsealing Bands / Sealing Bars

 

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.
We offer 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
