PREFORM FOR CONTAINER PRODUCED BY BLOW DRAWING

摘要

The preform (1) for manufacturing a package by blow molding, comprises three distinct elements assembled each other to a multi-layered side wall (3) of which 95% is flexible, a base (4), and an upper part (2) having an opening. Two elements are assembled by welding. Thickness of the upper part is twice a thickness of the side wall. External diameter of the opening is lower than an external diameter of the side wall. The side wall is cylindrical, oval or polygonal, and has a thickness of lower than 400 microns. Independent claims are included for: (1) a method for blowing of a preform; and (2) a package obtained by preform blowing.
