What are polyester converters?

Polyester converters are companies that specialise in combining raw polyesters, adhesives, silicone, tapes, foams, plastics, felts, rubbers, liners and metals, as well as other materials, to create new products.

Polyester converters also take continuous sheets and convert them into rolls for more convenient handling and transportation. These rolls of material vary significantly in size and weight — ranging from 2 to 200 in. wide and weighing as much as several tons. Polyester converters take these continuous rolls of thin, flat materials — known as webs — thread them though processing machines and convert or change the web of material into an intermediate form or final product.

For example, a polyester converters equipment might take a web of plastic film, cut it into lengths, and fuse their edges, thus converting it into plastic bags. This activity is known as web processing.
