Definitions

  • the present invention relates to an improved method for the sealing of plastic packaging, in particular for the sealing of contact zones where longitudinal seals meet cross seals on a packaging obtained in a vertical or horizontal form fill and seal packaging process (VFFS and HFFS process) .
  • VFFS and HFFS process vertical or horizontal form fill and seal packaging process
  • VFFS and HFFS packaging' s The packaging obtained in a vertical or horizontal form fill and seal packaging process, called VFFS and HFFS packaging' s, often show leakages which result in bags with a lower gas barrier than targeted. The consequence of such leakages are in the best case higher scrap rates when noticed during the packaging process and in the worst case a shorter shelf life of the packed food item than promised to the consumer.
  • the key to lower rates of defective packaging within a form fill and seal process is a correct seal of thickened sections consisting of multiple plies and in particular the seal on the transition point from two to multiple layers of superposed plastic film between the sealing jaws. The leakages are mostly located specifically in those areas (see Fig. 1) .
  • Various means have been tested to improve seals on plastic films.
  • Document US 4,070,222 discloses a method for the pre-treatment of superposed layers of thermoplastic film which are to be heat-sealed together. The heat pre-treatment is performed by hot air below the welding temperature.
  • US 4,812,192 discloses a process for cutting multiple plies of thermoplastic material to be sealed adjacent to a zipper via a heating cutting and sealing element.
  • the present invention aims to provide an improved method for the sealing of plastic bags on a vertical or horizontal form fill and seal machine.
  • the present invention aims in particular to improve the seal quality on transition points to multiple plies, in particular in zones where longitudinal seals meet cross seals of form fill and seal packaging' s.
  • the present invention discloses a method for the preparation of sealed packaging' s in a form, fill and seal process comprising the step of: - providing a plastic web on a form, fill and seal machine;
  • Preferred embodiments of the present invention disclose at least one, or an appropriate combination of the following features: - the intermittent preheating of said plastic web is performed by a hot stamp system;
  • the intermittent preheating is linked to a detection of the position on the plastic web to be heated
  • the plastic web is selected from the group consisting of monolayer polymer film, coextruded and/or laminated multilayer polymer film and polymer laminates comprising metallic layer or paper, or mixtures thereof.
  • Fig.l to Fig.3 represent critical zones of form, fill and seal packaging' s where longitudinal seals meet cross seals.
  • Fig.4 to Fig.6 represent the relevant part of a VFFS machinery where a preheating means (piston in this particular case) is connected to an eye-mark detection and a film-monitor counter.
  • the eye-mark detection allows the preheating of a critical zone of the FFS packaging by applying a hot piston stamping said critical zone just before it is longitudinally sealed, filled and then cross- sealed and cut in the same step.
  • the vertical or horizontal form fill and seal process is well known by those skilled in the art and can be performed on any thermoplastic polymer films.
  • monolayer polymer films as well as coextruded and/or laminated multiple layer polymer films are most frequently used, each layer having its own function and at least one layer being generally dedicated to the sealing function.
  • the quality of a heat seal with a specific polymer film on a vertical or horizontal form fill and seal machine depends on contact time, applied pressure and temperature of the seal jaws as well as on the thickness of the polymer film.
  • Increasing pressure of the seal jaws does not necessarily improve the seal quality and some sealing jaws present a recess in the critical zone where longitudinal seals meet cross seals to allow a homogeneous appliance of the pressure on the seal zones of the packaging. Higher temperatures would cause shrinking or even burning of the outside layer of the plastic film in direct contact with the seal jaw. At this point, the maximum applicable temperature for a specific plastic web is reached.
  • the sealing performance can also be improved by increasing the sealing time (contact time) . Nevertheless, increasing the sealing time will lower the speed of the packaging machine and consequently, the output of the packaging line.
  • An important parameter on a form fill and seal process is the sealing initiation temperature (S. I. T.) of the sealing layer of the plastic web.
  • Sealing initiation temperatures of the most common sealing polymers range between 80 and 160 0 C and most preferably between 90 0 C and 140 0 C.
  • Low melting sealing layer are generally specific polymer grades which are often more expensive .
  • a sufficient amount of heat energy needs to be applied to the polymer layer to be sealed. This heat energy is proportional to the temperature difference between the ambient temperature, which is the temperature of the plastic web, and the seal initiation temperature of the polymer used as seal layer of the packaging ( ⁇ T S. I. T. - T ambient) .
  • the S. I. T. is about 90 0 C. If the ambient temperature is 20 0 C, the polymer layer to be sealed is also at 20 °C and the ⁇ T to overcome is 70 0 C.
  • the S. I. T. is about 110 0 C.
  • the ⁇ T is reduced by preheating the polymer layer to be sealed specifically on the critical zone where longitudinal seals meet cross seals .
  • a selective or partial and intermittent preheating of the single web of plastic material before the actual sealing on the sealing jaw increase the temperature of the polymer film in those critical zones from room temperature (varying between -10 0 C until 40 0 C) until a defined temperature between 50 0 C and 80°C with the condition that this temperature always has to be lower than the S. I. T.
  • the preheating according to the present invention is performed selectively, partially and intermittently on specific transition points before the final sealing on the plastic film and without losing the control on the coefficient of friction of said plastic film.
  • the final goal being to save energy, to avoid product damage and to guarantee the sealing behaviour, including hot-tack properties, of the plastic film.
  • Preheating means are all those means allowing an intermittent and selective preheating. Among them, without being limitative, a piston with a stamp heated electrically and a laser beam, infra-red, ultra-sonic, localised hot air, ...
  • Type A Ordinary LDPE film (commodity)
  • Type B Specific polyethylene grade (more expensive) [0029] 50 ⁇ m mVLDPE/LDPE two-layer coextruded blown film with a sealant first layer of 10 ⁇ m mVLDPE Exact 0201FX layer with a density of 0.902 g/cm3 and melt-index of 1.1 (measured at 190 0 C with a 2.16kg load) and a 40 ⁇ m second layer consisting of Dow LDPE 300 E with a density of 0.924 g/cm and a melt-index of 0.8 dg/min (measured at 190°C with a 2.16kg load) .
  • Rhodamine test In order to identify leakages, bags are tested with the Rhodamine test. In this test, you cut away the seal and put Rhodamine solution in the seal. The seals are considered as closed if no single visible migration of Rhodamine is observed from the inside to the outside of the seal (pass-fail test) .
  • the T° of the jaws is constant at 110 0 C on each trial. Pressure is constant and equal to 400 N.
  • Leakage-free packaging could be obtained with intermittent preheating of the polymer film at 50 0 C with sealing times starting from 900 milliseconds.
  • the jaws T° is constant at 120 0 C on each trial. Pressure is constant and equal to 400 N. Pressure
  • (p) is constant and equal to 40 psi.
  • Preheating at 80 0 C of the polymer film allowed to decrease the sealing time down to 300 milliseconds and the speed of the packaging line could be increased.
