Abstract
A method of manufacturing a product, including extruding a parison, and separating the parison into parison halves by cutting a partially expanded parison or by pulling apart a longitudinally weakened parison, and forming the parison halves against corresponding mold halves. The method may also include applying a film against the parison halves and/or the mold halves, and forming the film and parison halves against the mold halves to produce multi-layer product halves. Apparatuses for performing the method are also disclosed.
