Definitions
- the present invention relates to the technical field of the measurement of the permeability to polymer wall gases such as in particular, but not exclusively, hollow body walls such as bottles, for example polyethylene terephthalate (PET).
- PET polyethylene terephthalate
- polymeric materials are relatively permeable to gases and water vapor. Oxygen transfer through the walls of a container containing a beverage may eventually lead to oxidation of certain compounds such as vitamins, fatty acids and proteins. Likewise, a loss of aroma and more generally a loss of organoleptic properties may result from low barrier properties of a food package.
- Permeability measurement techniques for polymeric materials are most often concerned with sheet materials and can be grouped into three categories: variable pressure measurements, variable volume measurements, so-called isostatic and isobaric measurements.
- Ox-tran ® denomination devices for the measurement of permeability to oxygen or Permatran ®, devices for the measurement of carbon dioxide permeability (see for example US 6,699,320 (column 4 lines 7 to 16)).
- conditioning conditioning
- air or oxygen is introduced into a continuous stream of a mixture comprising a high proportion of nitrogen and a small proportion of hydrogen ( between 0.5% and 5% hydrogen, typically two percent hydrogen in known oxygen permeability measuring devices).
- This continuous stream is sent with a very low, of the order of ten milliliters per minute.
- Oxygen is carried away by nitrogen, carrier gas, and the amount of oxygen is measured by coulometry.
- an infrared sensor compares the signal obtained for a standard amount of carbon dioxide in a standard cell and the amount of carbon dioxide that has passed through the polymer material and has accumulated in a measuring cell, as well as volume as the standard cell;
- a second so-called dynamic method used for polymeric materials having permeability values greater than 50 cc per square meter per day.
- this second method when the carbon dioxide passes through the polymer material to be tested to go into a measuring cell, a current value is obtained by the infrared sensor. When this current value changes linearly over time, a steady state is reached and the stationary signal obtained is compared with that obtained when a given quantity of CO 2 is injected in a volume identical to that of the measuring cell; a third method known as a continuous flow.
- Conditioning is a long step, which aims to ensure that the test conditions are in equilibrium.
- This conditioning time depends on many factors such as barrier properties of the polymer material, thickness of the polymer material, temperature.
- the conditioning time is all the more important as the developed surface of the bottle is large, as indicated in the document FR-2 844 596.
- the conditioning time is of the order of fifteen to twenty hours, which poses many practical problems for the monitoring of the measurements. It is also not possible, with the techniques known to date of the applicant, to perform more than one measurement per cell and 24 hours.
- the aim of the invention is to provide a method and a packaging installation that allows for a much faster measurement, yet is just as accurate and safe.
- the invention relates, in a first aspect, to a method for measuring the gas permeability of the wall of a hollow body made of a polymeric material, characterized in that it comprises a first so-called conditioning stage. during which a flushing gas sweeps said hollow body, and a second step, so-called measurement, during which a measurement gas is introduced in said hollow body, in that the flow rate of the purge gas is greater than the flow rate of the measurement gas and in that said purge gas is fed into said hollow body without mixing with said measurement gas.
- the flow rate of the purge gas is more than ten times higher than the flow rate of the measurement gas.
- the flow of flushing gas is, with respect to said wall, of the order of 200 cc per minute, the flow of measurement gas being, opposite said wall, of the order of ten ml per minute.
- the flushing gas and the measurement gas are different.
- the flushing gas may be an inexpensive gas, such as industrial standard nitrogen, the measurement gas being more expensive, for example nitrogen mixed with a proportion of hydrogen of between 0.5% and 5%.
- the method comprises a step of measuring a quantity of gas by coulometry, for example using an Ox-tran ® device supplied by Mocon or a similar device.
- the invention relates to an installation for implementing the method for measuring the permeability of the wall of a hollow body of polymer material, characterized in that it comprises a first circuit of a sweep gas adapted to sweep the hollow body and a second circuit of a measurement gas introduced into said hollow body, these two circuits being partly common and connected to each other via fluidic distribution means so as to such that the measuring gas is fed into said hollow body without mixing with said measuring gas.
- the distribution means comprise at least two inputs and one output and each input can be selectively brought into communication with the output.
- the distribution means are constituted by a valve comprising at least two separately openable channels, which channels each have an input and an output; preferably, the two channels are connected at their output, so that the output can be powered by one or other of the channels.
- a first input of the distribution means is connected to a measurement gas supply source associated with a device for measuring the quantity of a given gas, for example oxygen or carbon dioxide.
- a second input of the distribution means is connected to a source of purge gas, and the outlet of the valve is in fluid communication with a face of the polymer wall, a conduit also putting in fluid communication said wall face polymer and the apparatus for measuring the amount of gas.
- the invention relates to the application of the method or the installation shown above to the measurement of the permeability to oxygen or carbon dioxide of a hollow body, such as by example a cap, a tray or a bottle, including a PET bottle.
- the method and the installation according to the invention are of particular interest in the measurement of the permeability of containers, such as bottles, made of PET, manufactured by blowing (or stretching / blowing) in molds or having been treated to deposit a barrier coating after manufacture, to improve the impermeability to gases.
- containers such as bottles, made of PET, manufactured by blowing (or stretching / blowing) in molds or having been treated to deposit a barrier coating after manufacture, to improve the impermeability to gases.
- FIG. 1 is a schematic illustration of an installation for measuring the permeability of a hollow body comprising a packaging device according to one embodiment, in a first phase of operation;
- Figure 2 is a schematic illustration of the installation of Figure 1, in a second phase of operation.
- the measuring installation 1 comprises a gas analyzer 2, for example of the type sold under the reference Mocon Ox-tran.
- This gas analyzer 2 comprises a part intended for the supply of measurement gas and a measuring cell.
- the measurement gas outlet is connected, via a first duct 3, to a first inlet 4a of four-way type fluid distribution means 4 (more precisely to two inlets 4a, 4d, and two outlets 4b, 4c.
- the distribution means 4 comprise at least two inputs 4a, 4d and an output 4b, and each input 4a, 4d can be selectively brought into communication with the output 4b.
- the measuring cell is connected by a second conduit 5 to the hollow body 6 to be tested.
- a third duct 7 connects the outlet 4b of the distribution means 4 to the hollow body 6.
- a fourth duct 9 connects the outlet 4c of the distribution means 4 to the outside air 8.
- a fifth duct 11 connects the inlet 4d of the distribution means 4 to the source 10 of purge gas.
- a first input 4a of the distribution means 4 is connected to a measurement gas supply source associated with a quantity measuring apparatus 2 of a given gas.
- a second input 4d of the distribution means 4 is connected to a source 10 of purge gas, and the outlet 4b of the valve 4 is in fluid communication with one side of the polymer wall, a conduit 5 also putting into communication fluid the polymeric wall face and the gas quantity measuring apparatus.
- a neutral flushing gas for example nitrogen, is sent through the fifth duct 11 from the source 10 to the inlet 4d of the distribution means 4, and then is driven by a path 4bd of said means 4 to the outlet 4b of the valve 4, to go to the hollow body 6 via the third conduit 7.
- This neutral gas sweeps the hollow body 6 and out through the second conduit 5, to go through the analyzer 2, and be discharged to -the outside ambient air.
- This neutral gas is advantageously sent at a high rate, in this first circuit, for example of the order of 200 cc per minute.
- the measurement gas is sent to the first inlet 4a of the means 4 via the first duct 3 and this gas passes, via the channel 4ab, from the first inlet 4a to the outlet 4b for be introduced into the hollow body 6, via the third duct 7.
- the measurement gas is sent at a low flow rate, of the order of 10 ml per minute, and it leaves the hollow body 6 via the second conduit 5 to go to the measuring cell of the analyzer 2.
- the gas circuit used for the conditioning (first time represented in FIG. 1) is partly distinct from the gas circuit used for the permeability measurement (second time represented in FIG. 2) and this, unlike conventional permeameters.
- the hollow body 6 to be tested can thus be swept, before the measurement, by a first gas such as nitrogen, which is less expensive than the measuring gas, and this first gas can be sent under high flow rate into the hollow body, without the risk of mixing with the measuring gas.
- a first gas such as nitrogen, which is less expensive than the measuring gas
- the measurement method according to the invention of the gas permeability of the wall of a hollow body 6 of polymer material comprises a first so-called conditioning step during which a sweep gas sweeps the hollow body 6, and a second step, called measuring, during which a measuring gas is introduced into said hollow body 6, the flow rate of the purge gas being greater than the flow rate of the measurement gas and the purge gas being sent into the hollow body 6 without mixing with the measurement gas, the flow rate of the purge gas being more than ten times higher than the flow rate of the sample gas.
- the flushing gas and the measurement gas are different, and even more preferably for the measurement of the permeability to oxygen, the flushing gas is nitrogen, the measurement gas then being nitrogen mixed with a proportion of hydrogen of between 0.5 and 5%.
- the method according to the invention comprises a step of measuring a quantity of gas by coulometry.
- the hollow body to be tested is fixed in a sealed manner on a measurement support, in a manner known per se.
- the time required for proper conditioning can be controlled by traditional comparative tests.
- the applicant has thus been able to go from a conditioning time of 16 hours to a time of half an hour, for a measurement of permeability of a PET bottle of 26.5 g.
- the channels 4ac and 4cd of the distribution means 4 are closed.
- these channels are not essential, but are preferable in order to facilitate the purging of the circuits: for this purpose, the output 4c of the distribution means 4 is connected to the outside air, and the channels 4ac and 4cd are then open. in case of purging.
- the invention also relates to an installation for implementing the method for measuring the permeability of the wall of a hollow body 6 of polymer material, characterized in that it comprises a first circuit of a sweeping gas capable of sweeping the hollow body 6 and a second circuit of a measuring gas introduced into the hollow body 6, these two circuits being partly common and connected to each other via means 4 of fluid distribution in such a way that the measuring gas is fed into the hollow body 6 without mixing with the measuring gas.
- the method, as previously described, and the installation, as previously described, apply more particularly to the measurement of the permeability to oxygen or carbon dioxide of a hollow body 6.
