From coatings for hot beverage cups to salad bowls and carrier bags: what would the world of food packaging be without plastic? But what are the differences between PP, PE, PET & Co. and what advantages do they have? We give you an overview of the most important types of plastic for food packaging. Plastic, as it is also known colloquially, is everywhere in our everyday lives, because the material is characterised above all by its versatility. Whether it’s malleability, hardness, elasticity, breaking strength or temperature resistance: depending on the choice of macromolecules and the manufacturing process, plastic can be varied in numerous characteristics. As packaging, the material offers numerous advantages: It is light and at the same time stable, protects against moisture as well as dirt and – as already mentioned – is particularly versatile in its possible applications. In addition, as a packaging material it is appealing in presentation, as it can be transparent.
Ptfe glass and its positive properties
Almost all manufacturing industries share a challenge: in order to improve the profitability of operations, expensive machinery and equipment must be used ever more productively. Particularly affected are companies from the process industry that use very complex, i.e. highly automated and networked, production equipment. Shorter process cycles and higher availability also increase the demands on sealing elements. Because if processes are to be accelerated, more aggressive chemicals and higher temperatures are often used. Sealing materials must withstand these stresses without impairing their function. The selection of the optimal seal for the specific application and the coherent design of the entire sealing system is becoming increasingly important. Due to its many extremely positive properties, the high-performance material PTFE has become an indispensable part of many industries. Especially Pfte glass is often used.
History of Pfte
It all started with a refrigerator: Actually, the chemist Roy Plunkett wanted to invent a better refrigerator. The young chemist experimented with the gas tetrafluoroethylene, pressurised a canister with it and froze it. The next morning he wanted to continue his research, but the gas was gone. Instead, after a chemical reaction, the canister suddenly contained a whitish powder: polytetrafluoroethylene, or PTFE for short, now better known under the trade name Teflon. Now other things such as Pfte glass have been developed. You can find Pfte glass nowadays in many companies such as hardickptfe.com“>hardickptfe.com If you are interested in pate glass and want to know more about it do not hesitate to contact the company for more information. They offer a wide range of different Pfte glasses and belts. But pft has been also applied in different areas such as the kitchen. After the discovery, it was not about frying pans at all. The new plastic had many unusual properties: Non-flammable, and – as chemists say – very inert, extremely durable and with a very low coefficient of friction. Everything rolls off it. Researchers didn’t really know what to do with this strange plastic, plus it was very expensive to produce at first. Nowadays you can find Pfte in many kitchens on frying pans.
