Micro-perforated Plastic Material for Effective Storage of Hydrogen Peroxide

N.Mythili, N.Rajeswari

Chemical packaging is one of the challenging fields of packaging because the materials used for packaging should be chemically resistant, inert, negligent gas transmission, non-reactive, nonflammable, non-corrosive, temperature resistant, and light resistant. Glass containers and plastic bottles are widely used for packing of chemicals. In this paper the study has been focused on hydrogen peroxide, one of the most important inorganic chemical compounds and it is widely used in cosmetics and healthcare industries as a cleansing and bleaching agent. In higher concentrations, it is unstable where as in lower concentrations, it is almost stable. Decomposition of hydrogen peroxide liberates oxygen, water and heat. The liberated oxygen will occupy in the headspace of the container which may cause the container to bulge. The aim of this work is to achieve breathable characteristics for a package of plastic bottle containing H�O� of 12% concentration. A suitable experiment was identified to find out the volume of oxygen liberated by H�O�. During the primary level analysis, a method called micro perforation was identified as a solution for achieving breathable characteristics for effective storage of the product. The micro perforation was done in the closure (polypropylene) of the container. A head space analyzer was used to analyze the volume of oxygen accumulated in the headspace before and after the micro perforation. It has been found that the transmission of volume of the oxygen has been increased significantly.
