WebThe thermoforming process is used to make many different packaging articles, for example, tubs, pots, display trays and blister packs, and can be broken down into seven basic steps: 1. Making the sheet – normally by the cast extrusion method. 2. Heating the sheet. 3. Forming the pack by stretching the sheet either into or over a mould. 4. WebPolymer fibers of nanoscale diameter can be spun into tissue scaffold meshes. In addition to the cytokine-like signaling mentioned above, the thickness, density, and alignment of the fibers in ‘artificial ECM’ contribute to wound healing by encouraging invasion by cells and vascular regrowth (see Fig. 3.3).Polymers can be of biological origin, as NanoMatrix (now …
