3. Sheath blowing

3.1 Process overview

Sleeve blow molding is the main plastic film manufacturing process [AM3702] . It is mainly dedicated to PE, with major applications in packaging and agriculture.

In this process, described in figure 9 , the molten polymer is extruded through an annular die, which gives it the shape of a tube. This tube is stretched longitudinally...

Software tools

The simulations mentioned concern mainly laboratory work, often using "in-house" software. However, some work has used commercial software or has been funded by code developers, even if these developments have not yet been integrated into commercial versions. What's more, even if commercial software is not specifically dedicated to the development of structures, it can render estimable services by determining the mechanical...
