Реферат: Disclosed herein are embodiments of a glass pharmaceutical package with unique composition. The pharmaceutical package includes a glass container with a first and second surface, the first surface being an outer surface of the glass container. The glass container is formed from a borosilicate glass composition, the glass composition including: at least 75 mol% SiO 2 ; at least 10 mol% B 2 O 3 ; and Al 2 O 3 in an amount such that sum of SiO 2 , B 2 O 3 , and Al 2 O 3 is at least 90 mol%. The glass container has at least two of the following: a hydrolytic resistance of class HGA 1 according to ISO 720:1985, a base resistance of class A1 or class A2 according to ISO 695:1991, and an acid resistance of class S2 or class S1 according to DIN 12116 (2001).
