Polímeros nas indústrias de embalagens

Abstract

There are range of polymers that are used as raw material in the production of plastic packaging. With this diversity of options, the correct specification of the packaging becomes increasingly important, so as to accurately dimension them according to the protection needs of the product, considering its lifespan and the characteristics of the distribution and storage system. The choice of a thermoplastic to be processed and transformed into a finished product varies according to its characteristics and the purpose that the product will have, so to make that choice, it is necessary to distinguish which characteristics are important to take into account and to establish forms to quantify and qualify these characteristics by comparing the results of the available materials. According to this, a bibliographic study was developed on the processing of polymers in the rigid plastic packaging industry, both by extrusion and blowing and by injection and blowing, addressing the properties of the thermoplastic resins used as raw material, the production processes and methods of evaluating the quality of the finished product. The pharmaceutical sector was chosen for a particular case study, with the aim of studying the important aspects to be considered in the application of plastic packaging in the packaging of medicines. Thus, it was possible to check some important factors in the development of packaging for the quality assurance, safety and efficacy of the drug, such as: the pharmaceutical stability, the interaction between the product and the medication and the efficacy in the permeability of wet steam and gases.
