Polyester film is a high-performance film made from polyethylene terephthalate (PET) resin. The Polyethylene Terephthalate (PET) resin is made from Ethylene Glycol and dimethyl terephthalate (DMT). The PET resin used is of a similar intrinsic viscosity (IV) to fiber grade resin, used to produce polyester fibers, but has a higher purity. PET resin is made in special grades for specific film types and often contains slip modifiers. In comparison with other common plastic films, polyester film is characterized by high tensile strength, excellent dimensional stability, low moisture absorption, good retention of physical properties over a fairly wide temperature range (-70° to 150°C), excellent electrical properties, and good optical clarity. Because of its higher price relative to PVC, polyethylene, and polypropylene film, polyester film is generally considered a specialty film among all plastic films; however, markets of considerable volume have developed that require this strong, dimensionally stable film. Prices are higher than most commercial plastic films primarily because the manufacturing process is much more costly due to the need for an orientation step. (Most polypropylene film is also oriented.) The strength of polyester film requires rugged machinery for orientation. In order to assure strict gauge control, the buildings containing the film lines are carefully engineered and have very strong foundations and special reinforced flooring to prevent vibrations. Many end uses for polyester film have stringent specifications (e.g., photographic film and magnetic media) and require clean room conditions. Thus, capital costs are much higher than for other oriented films. Polyester Films have a unique combination of physical, chemical, thermal, and optical properties which result in the following: Strong, tough, brilliant and clear and ease of converting, laminating, extrusion coating, embossing, metallizing, printing, punching, corrugating, dyeing, stamping and forming. Polyester film is sold in various types, thicknesses, widths, and properties designed in many cases to satisfy the requirements of particular end applications. - Stewart Ren - Tel: - Email: - sales@after-printing.com - Address: - Unit 2505 Building Nengqun, No. 825 Hubin South Road, Siming District, Xiamen, China

Poliesterski film je visokih performansi film od polietilen tereftalata (PET) smole. Polietilen tereftalata (PET) smole od etilen glikola i dimetil tereftalata (DMT). PET smola koristi je sličan intrinzična viskoznosti (IV) vlakana razreda smola, koristi za proizvodnju poliesterskih vlakana, ali ima veće čistoće. LJUBIMAC smola se sastoji u posebnim razredima za određeni film i često sadrži skliznuti modifikatori. U odnosu na druge uobičajene plastične filmove, Poliester film karakterizira visoka vlačna čvrstoća, izvrsna postojanost, niske vlage apsorpcija, dobro zadržavanje fizikalna svojstva u prilično širokom temperaturnom rasponu (-70Â ° 150Â ° C), izvrsna električna svojstva, a dobar optički jasnoću. Zbog veće cijene u odnosu na PVC, polietilen i polipropilen film, Poliester film smatra se specijalnost film među sve plastične filmove; Međutim, tržište znatan volumen koji zahtijevaju ovaj jak, dimenzionalno stabilne film razvili. Cijene su više nego većina komercijalnih plastične filmove prije svega zato što postupak proizvodnje je znatno skuplji zbog potrebe za orijentaciju korak. (Većina polipropilen film je također orijentirani). Snaga Poliester film zahtijeva robusne mašine za orijentaciju. Kako bi se osigurala stroge vodomjera kontrolu, zgrada s filmom linije su pažljivo projektirana i imaju vrlo čvrste temelje i posebno ojačane podnice da bi se spriječile vibracije. Mnogo kraj koristi za Poliester film imati stroge specifikacije (npr., fotografski film i magnetski medij) i zahtijeva čistu sobu uvjete. Dakle, Kapitalni troškovi su mnogo veći nego za druge orijentiranih filmova. Poliester filmovi imaju jedinstvenu kombinaciju fizikalna, kemijska, toplinska i optička svojstva koja rezultiraju sljedeće: jak, tvrd, sjajan i čist i lakoće pretvorbe, laminiranje, najrazvijenija, reljefni tisak, metalizacije, tiskanje, bušenje, corrugating, bojenje, za tisak i oblikovanje. Poliester film prodaje razne vrste, debljine, širine i svojstva koje u mnogim slučajevima će sigurno zadovoljiti zahtjevi određeni kraj programa. - Stewart Ren - telefon: - Email: - sales@after-printing.com - Ulica: - Jedinica 2505 zgrade Nengqun, br. 825 Hubin Južna cesta, Siming Distrikta, Xiamen, Kina
