Provided this diluted dispersion is stirred or agitated to re-disperse immediately prior to addition into the vessel, it is now a simple matter of pouring the dispersion steadily and consistently over a period of at least 1 minute. Toner make-up tanks should be placed conveniently close to the addition point in the PET production process and vessels, and pipework and ancillary equipment should be sized according to good practice engineering principles and in accordance with desired batch make up frequencies (related to plant size and production throughput). Concentated Toner addition port.

In addition, laboratory tests indicate that these additives produce anti- fog properties at a slightly faster rate than other additive solutions. In addition, these films contain an anti-fogging additive specially formulated not to compromise any of this easy-peel functionality. Thirdly, the additive must meet all relevant food contact approvals.
