Abstract
A cyclic packaging process, such as VFFS or HFFS, packages a product with a viscosity of ≥100,000 centipoise without leaving substantial air pockets in the package, by utilizing a means (38) for restricting upstream flow of viscous product in the strand of tubing (24). The result is that packages of uniform weight of the viscous product can be made without substantial air pockets therein, and without having to use metal clips. An apparatus (10) for carrying out the process is disclosed.
