Abstract
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 for restricting upstream flow of viscous product in the strand of tubing. 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 for carrying out the process is disclosed. The cyclical packaging process comprises the steps of forming a longitudinally sealed tubing, pumping a viscous product into the tubing, restricting upstream movement of the viscous product and forming transverse seals. The apparatus associated with the process comprises a means for restricting upstream flow of viscous product. Conventional packaging apparatus/processes tend to leave air pockets in the product as the product does not flow to fill in the volume within the tubing. The invention aims to minimise weight variation between the plurality of packaged products.
