PET – Polyethylene Terephthalate
Polyethylene terephthalate and polybutylene terephthalate (PBT) are two common polymers used to manufacture plastic bottles and containers. Both materials come from combining ethylene glycol with terephthalic acid to form a chain of molecules which then gets extruded into strands before cooling, then being cut into pellets before being remelted to create the final product.
PET is an ideal material for food and beverage packaging due to its chemical inertness, excellent electrical insulating qualities, and virtually shatterproof nature.
PET is highly transparent, making it suitable for many applications. This property comes from its crystalline structure; when cooled, molten polymer forms spherulites with many small crystallites – making the polymer more translucent than amorphous spherical polymers.
PET can be recycled back into the same products that were made with it, such as fibre and bottles. This presents an immense benefit for the global recycling industry.
Like dogs, cats are low maintenance pets that require little more than food, water and a litter box. They possess great intelligence as well as being highly social animals that form strong bonds with their owners. Cats make excellent pet parents due to their easy care needs – just remember not to forget those treats!
Reptiles and Amphibians
Pets can range from birds and fish to insects and reptiles. Some breed them specifically for this purpose, while others serve primarily as livestock.
