PET

Polyethylene terephthalate (bottle and sheet grade)

Bottle-grade PET is the standard of beverage packaging thanks to its clarity, gas barrier and recyclability; intrinsic viscosity (IV) defines the application. Sheet grades serve thermoformed food trays and fibre grades textiles. Drying before processing is essential, as moisture lowers IV.

Overview

PET is the standard grade of the PET family in the general-purpose plastics group. It is used in applications such as water, beverage and oil bottle preforms, thermoformed food trays and lids, clear sheet and boxes. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.

Applications

  • Water, beverage and oil bottle preforms
  • Thermoformed food trays and lids
  • Clear sheet and boxes
  • Fibre and strapping

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for PET are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
