High density polyethylene plastic toxic.

This durable plastic is used in a wide variety of applications from transporting water to storing school books while students are in class. It is commonly used in cosmetics and personal care products food packaging materials and medical. Plastic 1 pet or pete stands for polyethylene terephthalate a plastic resin and a form of polyester. Low density polyethylene ldpe low density polyethylene s ability to be tough and flexible while also acting as a good moisture barrier allows it to be an excellent choice for food storage products like bags containers bottles and plastic wrap.

Polyethylene is a thermoplastic polymer that has a variable crystalline structure. Its manufacture employs the same method today. The epa estimates 5 7 of ldpe recycling number 4 is recycled in the united states. Low density polyethylene ldpe is a thermoplastic made from the monomer ethylene it was the first grade of polyethylene produced in 1933 by imperial chemical industries ici using a high pressure process via free radical polymerization.

Hdpe is commonly used in milk and juice bottles detergent bottles shampoo bottles grocery bags and cereal box liners. Ldpe is considered to be one of the less toxic plastics and can be reused for food products. Health concerns studies have found levels of antimony a toxic chemical leaching from water bottles that have been placed in heat for prolonged times. Like pet it is also considered safe but has been shown to leach estrogenic chemicals dangerous to fetuses and juveniles.

Ultrahigh molecular weight polyethylene or uhmwpe has a molecular weight about 10 times higher usually between 3 5 and 7 5 million amu than high density polyethylene hdpe resins. Ldpe has high ductility but low tensile strength which is evident in the real world by its propensity to stretch when strained. It is one of the most commonly produced plastics worldwide with tens of millions of tons produced every year. While plastic containers have been vilified for potential health risks some are ok to use.

Find out which are safe and which may be hazardous. Low density polyethylene ldpe is a very flexible material with unique flow properties that makes it particularly suitable for shopping bags and other plastic film applications. High density polyethylene or hdpe is a type of plastic that s tougher and stronger and can endure higher temperatures than most other polymers. Although pete does not contain bpa or phthalates it s always best to make sure that your water bottles are not temperature abused.
