- VFFS vertical form, fill, and seal
- a lower hermetic seal forms the upper seal of the lower package
- an upper hermetic seal forms the lower seal of the upper package.
- the upper package is then filled with product, the tube is advanced downwardly through the jaw device, and then the cycle is repeated when the upper edge of the upper package, and the lower edge of the following package, is disposed between the jaws of the jaw device.
- VFFS vertical, form, fill, and seal
- a knife 12 is disposed on one side of the flattened, longitudinally sealed tube 14, and a hardened reaction pad or anvil 16 is disposed on the opposite side of the tube 14, with the tube located between the knife 12 and anvil 16.
- the knife 12 is urged under pressure against the anvil 16 to cut through the film of the tube 14, trapped between the knife blade 18 and the anvil 16, by a pressured crush-cutting action.
- the knife 12 and the anvil 16 both rotate in phase and in opposite rotational directions as shown by the arrows in Figure 1 so that the knife 12 and the anvil 16 engage so as to cut packaging film material, in the form of a flattened tube as described below, centrally located therebetween.
- the knife 12 is rotated about an axis X orthogonal to the longitudinal direction L of the tube 14 and parallel to the surface of the anvil 16 and the cutting edge 20 of the blade 18.

- the pressure strips 126, 128 urge the flattened tube 114 against the heated anvil 1 16 so that transverse hermetic heat seals 132, 134 are formed in the flattened tube 1 14 on opposite sides of the transverse cut 136 made by the knife 1 12.
- Each pressure strip 126, 128 is pressed against the heated anvil surface thereby simultaneously heat sealing together opposed sides of the flattened tube 1 14 to form an elongate transverse hermetic seal 132, 134 in the vicinity of each cut end of the flattened tube 1 14.

- the pressure strips 126, 128, compressed against the bias of the biasing elements 133, 135 ensure uniform high pressure along the flattened tube 114 which forms highly and uniformly bonded hermetic seals 132, 134 of predetermined narrow width. After release of the sealing pressure, the pressure strips 126, 128 are urged outwardly again by the outward bias of the biasing elements 133, 135 so as return to their original rest position.
- the pressure strips 126, 128 locally press the film material of the tube 1 14 against the heated anvil 116 to form the two spaced hermetic seals 132, 134 of defined width determined by the profile of the outer edge 131 of the elongate bar 126, 128.
- the plural layers of the film material of the tube 1 14 are pushed into the channels 162, 164 by the respective elongate bars 126, 128 to form an arcuate hermetic seal.
- planar hermetic seals are formed.
- the elongate pressure strips 126, 128 are parallel to the knife 1 12 and so the entire assembly of the knife 1 12 and the elongate pressure strips 126, 128 on opposite sides thereof is mounted at an inclination to the longitudinal direction of the elongate holder 121.
- elongate pressure strips 126, 128 of rigid material such as metal which are urged against a rigid heated anvil 1 16, which may have a complementarily profiled channelled surface or a planar surface provides the advantage of a high strength seal of minimum width.
- the pressure strips 126, 128 can exert a high pressure over a small surface area, providing an enhanced heat seal as compared to providing a lower pressure seal over a greater width. Therefore a narrower heat seal can provide improved hermetic performance and durability as compared to a wider seal.
- the elongate pressure strips 126, 128 are biased by concealed elastic resilient material, which is not subject to external contact and so is safely retained within the slots 127, 129, and is not subjected to excessive wear.
- the entire width of the assembly of the knife 112 and the elongate pressure strips 126, 128, all inclined to the longitudinal direction of the elongate holder 121, is 8 mm, whereas in the known device the entire width of the assembly of the knife 12 and the heat seal devices 26, 28, all parallel to the longitudinal direction of the elongate holder 21 is 20 mm.
- FIG. 6 shows two adjacent packages 200, 202 which have been separated by a cut formed by the knife 1 12.
- Each package 200, 202 has a cut transverse edge 204, 206 which is inclined at the angle ⁇ (exaggerated in the Figure) to the longitudinal direction of the package 200, 202. The angle is sufficiently small that it would not ordinarily be noticed by the consumer.
- a heat seal, forming a hermetic seal 208, 210, is provided at the end of each package 200, 202.
- An unsealed endmost portion 212, 214 adjacent to the cut transverse edge 204, 206 has a width corresponding to one half of the knife thickness.
- the unsealed endmost portion 212, 214 has a typical thickness of 0.5 to 1.5 mm, most typically lmm, which can be compared to a typical thickness of 2.5mm of the corresponding unsealed endmost portion produced by the known device of Figures 1 to 3.
- This material saving is achieved by reducing the amount of unsealed material at the ends of the packages that has no functional purpose with respect to forming a hermetic seal.
- the heat seal can be narrower than known heat seals by using the specific pressure strips against the heated anvil, providing even greater packaging material savings.
- the heat seal has a width of from 1 to 4 mm, optionally 1 to 2 mm.
- Such a film material saving has potentially enormous impact on high volume production of products such as snack foods.
- the Applicant and its related companies form part of one of the largest snack food companies in the world, and it is estimated that this packaging material saving cumulatively amounts to a global cost saving in packaging material of many tens of millions of dollars per annum, and, importantly, a saving of approximately 16 thousand tonnes of carbon dioxide production per annum.
- This invention therefore may yield very significant reductions in the carbon footprint of the packaging of a wide variety of products, particularly snack foods.
- angle and dimensions exemplified above are merely indicative of an angle size and dimensions that may be used in accordance wit the present invention, and that these parameters may be varied depending upon a number of factors, including package size, shape and dimensions.
- the jaw device and method may be used to produce primary packages of a variety of products, of which snack foods are only a preferred example.
- the jaw device and method may also be adapted to produce secondary packages, for example multi-pack packaging.
- plural knives may be mounted about a common shaft disposed along the rotational axis and mutually angularly separated, so that for each cycle of rotation of the common shaft, plural cuts are made by respective knives, and corresponding plural packages are separated by the cutting action for each rotational cycle of the shaft.
- Plural anvils would be correspondingly provided.
- the jaw device may have a translational action rather than a rotary action, and either or both of the elongate holders for the knife and the anvil may be translationally reciprocated.
