The Polypack ILB/CMB machines provide versatility packaging solutions:

  • Automatic shrink wrap systems

  • An optional case packer module

  • Various product container shapes, sizes on same run


Polypack ILB/CMB packaging solutions can be engineered as handload models or with fully automatic product collation modules. Polypack’s signature “bucket” conveyor sets the Polypack ILB/CMB series of shrink wrapping machines apart from others, in that:

  • It is designed specifically for your products and applications

  • Product travels in a straight line in custom engineered “buckets”

  • Product remains on the bucket conveyor for the duration of the wrapping, cutting, and sealing process before entering the shrink tunnel

  • Hand-loaded intermittent motion shrink wrapping at speeds of 25 packs/minute in single lane, and 50 packs/minute in dual lane

  • Continuous motion wrapping at speeds up to 100 packs/minute


As an option, our patented robotic ROKH® pick & place gantry can be added for unstable products, such as ovals and tubes. With Polypack’s ROKH® pick & place, products can be stacked, split, rotated, or collated into any configuration. With the addition of optional case equipment, the Polypack ILB/CMB is an excellent case packer packaging solution.
