Blow Molding

Term from Packaging industry explained for recruiters

Blow molding is a manufacturing process used to create hollow plastic products like bottles, containers, and other packaging items. Think of it like blowing up a balloon inside a mold - hot plastic is inflated into a mold cavity to take its shape. This process is commonly used in packaging, beverage, and consumer goods industries to make items like water bottles, shampoo containers, and car parts. When you see this term on a resume, it usually indicates experience with plastic manufacturing processes, particularly in packaging production.
