Polyester sheet and its application in the manufacture of heat-resistant polyester containers

The sheet is suitable for the production of rice cookers, the composition of which is polyester and polyolefin. The mass fraction of PET is from 99% to 90%, and that of polyolefin is from 1% to 10%. Wherein (1) the intrinsic viscosity of the polyester [η] ≥ 0. 70dL / g, the mass fraction of the copolymerized DEG is 0.5% to 3.0%, the mass fraction of the cyclic trimer is not more than 0.70%; (2) After heating at 150 °C for 10 min, extract the sheet with 50% ethanol to no more than 10 μg/cm2. For example: a PET with a mass fraction of 97% (intrinsic viscosity of 1. 00 dL/g, a mass fraction of DEG of 1.2%, a cyclic trimer of 0.3%) and a low density of 3% Ethylene sheets (ethanol extracts of not more than 2 μg/cm2) were vacuum-formed into small cans filled with boiling water and heat-sealed into containers with lids. After 5 days, the water was odorless.
