Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offsetâsplit into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon.
About the Seminar. Lamination of Flexible Materials for Packaging is designed to give engineers and others an understanding of lamination processes and the properties of the resultant laminates utilized in flexible packaging. Monolayer flexible materials often fall short in delivering the needed properties.
The right selection of packaging materials and technologies maintains product quality and freshness during distribution and storage. Materials that have traditionally been used in food packaging include glass, metals (aluminum, foils and laminates, tinplate, and tin-free steel), paper and paperboards, and plastics. Moreover, a wider variety of plastics have been introduced in both rigid and flexible forms.
