Study of static cushioning properties and construction of a database for static cushioning properties

摘要

AbstractThe rapid advance of computerization in industrial package design has led to a strong tendency toward CAD/CAM systems using personal computers for quick design and trial manufacturing.New tools based on a database of the cushioning properties of packaging materials will be needed for the design of package cushioning.Using a compression testing machine with computer control, an attempt has been made to construct such a database with registered characteristics for 47 samples of foamed polyethylene, foamed polypropylene and foamed polyethylene‐polystyrene.This database offers the following functions and is recorded on floppy disk:(i) calculation of static cushioning properties (value);(ii) print‐out of the computed results;(iii) drawing characteristic figures for designing package cushioning;(iv) indicating optimum value of static cushioning properties;(v) additional registration of new samp
