French Packaging Technology (I)

Remove bottle odors France's fine wines will be stored locally in wine bottles in the future, without worrying about deviations in taste. Preteux Bourgeis, a company specializing in the production of cork stoppers for sparkling wines, and Orleans Bourgeois, a cork stopper for the production of “bubble-free” wines such as bougainvillea or Bordeaux, have experienced long and difficult times. The research has finally achieved fruitful results - adding silicone stoppers will not produce "odor" due to the interaction between cork and wine.
“We will not give up the use of cork stoppers,” said Nicolas Lisabeaut, Director of Operations at Barange. “We have used this cork material since ancient times. It guarantees the ageing of wine and it must not be replaced.” Scientists would like to know why stoppers Produces odors. They could not think of the possibility that some mysterious ingredient in natural cork causes odor. Since they can't get rid of odors, they choose another way to prevent it from evaporating in the wine. So think of silicon. Silicone inserts have a characteristic: it can be waterproof, it can also eliminate odors, but also has a breathable, through the gas such as silicon dioxide and oxygen. Putting a small hole in the bottom of the cork will not only prevent the wine from being contaminated, but also ensure the normal “breathing” of the wine.
Barange Corporation and Preteux Bourgeois, two companies, applied for patents for "storage agents" in the name of the subsidiary Cortex. After a year of marketing, this technology has been applied to 1 million cork stoppers.
Cortex received 7 million orders, including Australian orders. “Now our experts send us bottle stoppers,” explained Nicolas Lisabeaut. “We are responsible for punching and adding storage agents.” In the future, the storage technology may be applied to corks plants on five continents. But do we really get rid of the odor caused by the cork? Not exactly that. "If the odor is a pre-packaged bottling process, the storage agent will not achieve the deodorization function, but this possibility is very small."
Temperature Control Technology Wine, food, medicine, and other items are sensitive to temperature changes during storage and transportation. The Emball'ISO company in Lyon succeeded in developing a polystyrene foam with a sealed structure, which is the most insulating product on the market today and has a thermal conductivity of 0.025 W/m·c. This bubble is currently sold all over the world. The trademark is the star of insulation. The company is currently investigating materials that are five times better and have a thermal conductivity of 0.005 W/m·C, which is mainly used for packaging and building thermal insulation.
Mr. Jean Claude Champeymond, Director of Operations of the company, said: “It is very difficult to know the temperature change of items during transportation. For valuables, people will be equipped with an electronic tracker to confirm the items are transported by the cabin or trailer. The tracker will save the data. After arriving at the destination, it was deciphered by a personal computer, but the device was very expensive, worth tens of euros, and did not include the time it took to decipher the data. For non-precious objects, people would use lozenges or cheap control belts. (It takes only 1-2 Euros.) The temperature changes beyond the required range, the lozenge or control strip will change color, but the color change does not reflect the magnitude or duration of the temperature deviation.” (To be continued)
