The Inpak Systems IS-325 is a sleeve steam heat tunnel that is used to shrink a label on a bottle, barrel, can or cup. Steam is used as the source of heating, and it has the features of fast heating, even heating, wrinkle-free, adjustable power, and perfect shrinking. The machine body is made of stainless steel, which includes a heat-preservation layer. Not only does this save energy, but it also conforms to international security standards. The entire machine is water-tight, and a stainless steel water receiver is mounted in the bottom to collect condensed water.

The IS-325 sleeve steam heat tunnel is easy to operate and maintain, and is widely used in the mineral water, pure water, carbonated drink, and tea industries. This steam heat tunnel machine uses a steam-shrink model with an all-steel structure. The machine has the advantages of being energy efficient with minimal power consumption. Simple adjustments can achieve nice-looking shrink effects on any shape of bottle.
