Use of Differential Scanning Calorimetry in Developing and Applying Films for Flexible Packaging

Source

The fundamentals of differential scanning calorimetry (DSC) are presented, with particular emphasis on polymer systems used in flexible packaging. The use of DSC techniques to distinguish film properties from the properties of base polymers is described. Techniques for quantitative determination of melting points, percentage composition of dry-blended film resins, and latent heat of fusion are given. Qualitative analysis of crystallinity characteristics is described.

Application of these analytical techniques to considerations of film extrusion, extrusion coating, and heat seal performance demonstrates the value of DSC in selecting and characterizing films used in flexible packaging.
