Polyethylene terephthalate offers a wide range of applications, especially in the packaging sector. PET resins are commonly used in manufacturing bottles, containers and packaging tapes. It proves to be an excellent barrier material, preventing the transfer of chemicals which makes it most suitable for food and cosmetics industry. PET resin is commonly used thermoplastics as it offers many benefits such as: The polymers are easily available and inexpensive PET polymers are hi

Polyethylene Terephthalate (PET) Resins are performance polymers. They offer a wide range of applications in the end segment markets. PET plastic are prominent in markets such as Transportation, Automotive, Electrical/Electronics, Household Appliances, Packaging, and Textile. As PET material is an excellent water and moisture barrier it used extensively in packaging industry especially for consumable packaging (water bottles, soft drinks, packed foods). The high mechanical st

Polyethylene Terephthalate commonly known as PET or PETE is the mostly used polymer in the world. It is naturally transparent and semi-crystalline plastic used widely for products used in our day to day life. PET polymer is better termed as “Polyester” in the textile industry. It is widely used as a fiber for clothing as it is an excellent moisture barrier and also used for bottling and packaging on large scale. The major share of PET plastic produced comprises of synthetic f

Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects. Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their actual name derives from this specific ability. Plastics are typically organic polymers of high molecular mass and often contain other sub

Check part 1 https://www.naraloca.com/post/history-of-plastic-part-1-2 The development of plastics has evolved from the use of natural plastic materials (e.g., chewing gum, shellac) to the use of chemically modified, natural materials (e.g., natural rubber, nitrocellulose, collagen, galalite) and finally to completely synthetic molecules (e.g., bakelite, epoxy, polyvinyl chloride). Early plastics were bio-derived materials such as egg and blood proteins, which are organic pol

Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins. It may also be referred to by the brand names Terylene in the UK, Lavsan in Russia and the former Soviet U

Recycling PET bottles A long and complex process chain is needed to turn a used bottle into usable raw material. It all starts with the collection of the bottles and pressing them into bales. Afterwards, the bales are opened, sorted out and grinded. The flakes obtained are washed (cold and hot) and separated from the polyolefin, which comes from caps and gaskets. After drying and metal separation, the flakes are practically ready to be filled into silos or big bags. A new cyc

Polyester is manufactured by one of several methods. The one used depends on the form the finished polyester will take. The four basic forms are filament, staple, tow, and fiberfill. In the filament form, each individual strand of polyester fiber is continuous in length, producing smooth-surfaced fabrics. In staple form, filaments are cut to short, predetermined lengths. In this form polyester is easier to blend with other fibers. Tow is a form in which continuous filaments a

Impact of microplastics on wildlife There are several ways in which plastics can interact or influence wildlife. In the case of microplastics (particles smaller than 4.75 millimeter in diameter), the key concern is ingestion. Ingestion of microplastics have been shown to occur for many organisms. This can occur through several mechanisms, ranging from uptake by filter-feeders, swallowing from surrounding water, or consumption of organisms that have previously ingested micropl

Microplastics are very small pieces of plastic that pollute the environment. Microplastics are not a specific kind of plastic, but rather any type of plastic fragment that is less than 5 mm in length according to the U.S. National Oceanic and Atmospheric Administration (NOAA). They enter natural ecosystems from a variety of sources, including cosmetics, clothing, and industrial processes. Two classifications of microplastics currently exist. Primary microplastics are any plas

There is some debate over whether recycling is economically efficient. According to a Natural Resources Defense Council study, waste collection and landfill disposal creates less than one job per 1,000 tons of waste material managed; in contrast, the collection, processing, and manufacturing of recycled materials creates 6–13 or more jobs per 1,000 tons. However, the cost effectiveness of creating the additional jobs remains unproven. According to the U.S. Recycling Economic

BoPET (biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the most well-known trade names are Mylar, Melinex, and Hostaphan. BoPE
