[Analysis Case] Layered Structure Analysis of Heat-Resistant PET Bottles for Food Use
It is possible to identify the components of each layer of PET bottles using TOF-SIMS.
PET bottles allow a small amount of air (oxygen) to permeate, making the beverages inside susceptible to the effects of oxygen intrusion from the outside, which leads to a deterioration in quality. To address this, various innovations have been made in PET bottles. For example, by inserting an oxygen-absorbing layer between the PET layers, as shown in Figure 1, the deterioration of beverages is prevented, preserving their taste. This document presents the results of analyses conducted using TOF-SIMS to confirm what the oxygen-absorbing layer is composed of.
