75 Jahre PET – Siegeszug als Flaschenmaterial

Der Kunststoff Polyethylenterephthalat oder kurz PET feiert in diesem Jahr seinen 75. Geburtstag. Ursprünglich als Alternative zur Herstellung von Textilfasern entwickelt, ist das Material heute eines der wichtigsten in der Verpackungs- und Textilindustrie. Sein weltweiter Siegeszug begann zwar erst Anfang der 1970er-Jahre, dafür hält er aber bis heute an: PET-Fasern werden unter anderem bei der Herstellung von reißfesten Bekleidungs- und Geotextilien verwendet. Flaschen aus PET haben mit zahlreichen Vorteilen die Konsumentennachfrage und damit den Getränkemarkt nachhaltig geprägt und werden immer häufiger zum Abfüllen verwendet.

Dickson schrieben 1941 Geschichte, als sie in der Kleinstadt Accrington im Norden Großbritanniens erstmals den formbaren Stoff Polyethylenterephthalat herstellten. In ihrem Experiment produzierten sie ein Polyester aus Ethylenglykol und Terephthalsäure, das hohe Schmelztemperaturen aufwies. Anfänglich sollte das Material zur Herstellung robuster und günstiger Textilfasern dienen, um diese als Alternative zu japanischer Seide und Nylon einsetzen zu können. Früher wurde der Wertstoff zu 100 Prozent aus Erdöl oder Erdgas hergestellt, heute gibt es bereits erste Flaschen auf biobasierter Rohstoffbasis. Siegeszug im Flaschenformat Weltweite Bekanntheit erlangte PET durch den Einsatz bei der Produktion von Getränkeflaschen. Anfang der 1970er Jahre kamen die ersten PET-Flaschen in den USA großflächig auf den Markt. Vor allem Hersteller von Softdrinks nutzten das Material zur Abfüllung ihrer Produkte und läuteten damit den Siegeszug des Wertstoffs ein. Im Gegensatz zu herkömmlichen Glasflaschen bietet PET Bruchsicherheit, ein geringeres Gewicht sowie ein einfacheres Handling. Mehr als 97 Prozent der Einweg-PET-Pfandflaschen gehen in Deutschland laut einer aktuellen Umfrage der Gesellschaft für Verpackungsmarktforschung im Auftrag des Forum PET zurück ins Recycling. Der Rest wird energetisch verwertet. Rund ein Drittel des Rezyklats wiederum wird zur Produktion neuer Einweg-PET-Flaschen verwendet. In anderen Anwendungsbereichen wie zum Beispiel der Textilbranche substituiert recyceltes PET zudem den Einsatz von neuem PET. Als Verpackungsmaterial für Lebensmittel und Getränke erfüllt das Material strenge gesetzliche Kriterien. Bei der Produktion von PET werden zum Beispiel keine Weichmacher wie Bisphenol A (BPA) eingesetzt. Sogar Babynahrung darf daher in PET verpackt werden. Die PET-Branche optimiert die Flaschen bis heute kontinuierlich – zum Beispiel im Hinblick auf ihr Gewicht. Moderne 1,5 Liter-Lightweight-Flaschen für Mineralwasser aus PET erreichen heute ein Gewicht von unter 30 Gramm. Jedes Jahr kommen rund 17 Milliarden PET-Flaschen auf den Markt, Tendenz steigend. Durch die Materialoptimierung vergrößern sich außerdem die Anwendungsbereiche. Weiterführende Literatur:Kunststoffverpackung Blisterverpackung Klarsicht Faltschachtel

Special occasion dresses

Select the appropriate costumes for a special occasion. You should not try to be trendy or hip when selecting one because a gown should to reflect the most feminine part of your personality. One shoulder lace ball gowns have the classic large bell shaped bottom, but the bodices can vary widely. There are some things that you should consider when choosing a gown for a ball. Maybe you want to create an impression of wealth and elegance through your gown. The material is the first thing you want to pay attention to if you want the elegant well-to-do look. Some designers create gowns that have lace bodices with skirts of other materials while some have the entire gown of the same fabric. The truly classical ball gowns are made of satin, and impart a sense of wealth and grace. Materials that do not occur in nature can provide a modern twist to the gown. For instance, metallic materials constructed from silk thread over polyester will shimmer in all lights. If your gown is rich in fabric, then cotton won't do at all. You should choose translucent or shiny materials if there are many curves and dips in the material of the skirt. The next issue that should be addressed is the cut of the gown. The cut you choose depends on whether you're going for a classical look or a modern one. The classical look is best suited to those with prominent curves and well defined figures. Classical ball gowns are usually off-the-shoulder, have cap sleeves, and have an accompanying sash or shoulder wrap. These gowns usually are laced or buttoned, not zipped. Classical ball gowns usually have a matching bodice and skirt. The waist is also slightly cinched, with the hooks concealed in the back. The bust line is decorated with folds of material that match the shoulder sash. The bodice should have some kind of embellishment, like embroidery or an embossed print. The modern styled ball gowns may be the best pick for you if you are a thin or petite woman. There are modern styles that have a tank top with spaghetti straps and zipper in the back. This style can detract the appearance of a fuller woman but is flattering to very thin or petite women. Modern ball gowns usually have lace tops which contrasts with the smooth material of the bell shaped bottom. I wish you to become the most watched people in the party.
