A composite belt assembly for a band sealer is provided. The composite belt assembly comprises a belt comprising a main belt; a first layer; and a second layer; wherein the first layer is arranged in contact with the main belt, preferably between the second layer and the main belt; and the first layer includes an attachment portion, configured to contact the main belt and the second layer. There is also provided a band sealer comprising a composite belt assembly and a packaging line comprising the band sealer. There is further provided a method for heat sealing a package, comprising providing a composite belt assembly, gripping a bag neck of the package using the composite belt assembly, guiding the bag neck of the package along a movement plane using the composite belt assembly providing a sealing element configured for heat sealing a plastic material of the bag neck, and applying heat to at least part of the bag neck through the first layer of the composite belt assembly using the sealing element.

The present disclosure is directed to a compression belt for inflation and sealing devices. The device may include an inflation assembly, a heating assembly, and a drive mechanism. The inflation assembly may direct fluid between first and second overlapping plies of a flexible web material to inflate chambers between the plies. The heating assembly may be operable to heat the first and second plies of the web material to create a longitudinal heat seal that seals the fluid in the inflated chambers. The drive mechanism may drive the web material in a downstream direction. The drive mechanism may tension the web material against the heating assembly. The drive mechanism may include a first belt including a high grip material on a surface that contacts the web material to grip the web material during heating by the heating assembly.
