Container supply - from stacked inner linings to be sealed into outers to give double wall

摘要

The rotary head with its heated dies takes the beaker-shaped thin-walled inners, and carries them individually round to a mould where they are inserted into the outer container and sealed into place by a combination of heat and differential pressures. A double-walled container is assembled for food/dairy products for vending machines without undesired thin or thick zones in the plastic film material.
