What is the Best Way to Process Clear Retort Pouches Through the Value Chain? Examining the Effects of Converting, Retorting and Drop Tests on Stand-up Pouches Containing SiOx-coated PET

摘要

The retort pouch market has been an area of intense development over the past few years, as consumer goods companies are looking to provide more convenient, better tasting food to the consumer. Clear retort pouches have been making in-roads into applications where the ability to microwave, visibility of the product and metal detection capabilities are all important. In particular, oxide-coated films offer several benefits, such as no yellowing, no retort shock, full FDA approval and recyclability compared to other clear barrier films.rnIn spite of these advantages, one reason oxide-coated clear retort pouches have not gained increased market share is due to their cost. However, recent studies have shown that a 3-ply lamination can actually provide sufficient barrier properties after pouch-making and retorting without significantly increasing costs. This study goes a step further, to examine the effects on barrier properties of creating a stand-up pouch, putting it through different retort conditions, and looking at the effect of dropping it.
