Standard Test Method for Determining Integrity of Seals for Flexible Packaging by Visual Inspection Ingestion-build-256245 ISO 21302-2 is the second1. Scope 1. 1 This test method covers the determination of channels in the package seal down to a width of 75 m [0. 003 in.] with a 60100 % probability (see Section 8). 1. 1. 1 The ability to visually detect channel defects in package seals is highly dependent on the size of channel, the degree of contrast from sealed and unsealed areas, the amount and type of adhesive between the two package layers, reflecting light angle, types of material used, the
