I-Bar Sealer The i-Bar sealer is an essential piece of equipment for any business that requires wrapping and sealing products. This specialized machine is designed to wrap products and shrink the film around them, making them tamper-proof and ensuring their safety. It is easy to operate and requires no maintenance, making it ideal for businesses of all sizes. The 450SPS i-Bar sealer gets a sealing size of 450*1.0(mm), while its weight read only 15kg. To use the I-Bar sealer, put the roll of centerfold shrink film (PVC or Polyolefin) on the film roller and open it through the film separator. Then adjust the temperature according to the film and place the packet in the film pocket. Pull down the lever, and the machine automatically cuts and seals the packet. Turn the packet and seal the other end as well. Finally, with the help of a heat gun, the product film will shrink and complete the packaging process.
