High Speed Line - Speed Flex The Speed Flex operates as the Combi Flex but is divided into a two-step process. In the Hood Applicator, the film hood is automatically applied over the load. Then the load is conveyed into the Easy Flex, where the shrinking takes places. The shrink lines described above are combined units, but as all our machines have a modular design, each unit can also act as stand-alone machine depending on customer requirements. The capacity of the Speed Flex is 200+ loads an hour.
