This document specifies two methods for assessing the tendency of flexible plastic films and sheets to adhere to one another when left in contact for some time, at a specified temperature and under light pressure. One method is qualitative and the other is quantitative.
Abstract
Overview
SIST EN ISO 11502:2019 specifies standardized test methods to determine the blocking resistance of flexible plastic films and sheeting. Blocking resistance is the tendency of adjacent layers of plastic film or sheet to stick together after being in contact for a period of time, particularly under applied heat and pressure. This international standard outlines both a and a method to assess this property, ensuring consistent testing, reporting, and quality assurance across the plastics industry.
