When the product polyethylene film has been analyzed, formulated, sampled and produced, the quality control department performs all the measurement of product parameters defined during the product design process. These parameters are usually summarized in the documents of the sales process (essentially the specifications of supply – see below).
Depending on the terms of the supply contract, trained staff responsible to perform measures, do the job carrying out the measurements using instruments operated in the controlled mode. Other parameters (eg the thickness of the film) are acquired directly from the production machines and the computed values included in the tables of data quality certificates.
The control data are collected and suitably stored from 2001 year for each reel of film of polyethylene produced by Ticinoplast Srl. A similar archiving policy has fulfilled for samples that can be either sent to the customer and simultaneously stored in Ticinoplast for subsequent comparisons of data. Such storage of samples has a more limited time period because it is not possible, “the digitization of champions” and in any case the length of the period it is agreed with the customer.
