Abstract:
Disclosed herein are delamination resistant glass pharmaceutical containers which may include an aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to ISO 720-1985 testing standard. The glass containers may also have a compressive stress layer with a depth of layer of greater than 25 μm. A surface compressive stress of the glass containers may be greater than or equal to 350 MPa. The delamination resistant glass pharmaceutical containers may be ion exchange strengthened and the ion exchange strengthening may include treating the delamination resistant glass pharmaceutical container in a molten salt bath for a time less than or equal to 5 hours at a temperature less than or equal to 450° C.
Abstract:
One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.
Abstract:
Coated pharmaceutical packages are disclosed. The coated pharmaceutical packages may include a glass body formed from one of a borosilicate glass composition that meets Type 1 criteria according to USP or an alkali aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to the ISO 720-1985 testing standard. A low-friction coating may be positioned on at least a portion of the first surface of the glass body the low-friction coating may include a polymer and a coupling agent disposed between the polymer and the first surface of the glass body. A coefficient of friction of the portion of the coated pharmaceutical package with the low-friction coating is at least 20% less than a coefficient of friction of a surface of an uncoated pharmaceutical package formed from the same glass composition.

Abstract:
Delamination resistant glass containers with heat-tolerant coatings are disclosed. In one embodiment, a glass container may include a glass body having an interior surface, an exterior surface and a wall thickness extending from the exterior surface to the interior surface. At least the interior surface of the glass body is delamination resistant. The glass container may further include a heat-tolerant coating positioned on at least a portion of the exterior surface of the glass body. The heat-tolerant coating may be thermally stable at temperatures greater than or equal to 260° C. for 30 minutes.
Abstract:
Coated pharmaceutical packages are disclosed. In embodiments, a coated pharmaceutical package includes a glass body comprising a first surface. A low-friction coating may be positioned on at least a portion of the first surface of the glass body. The low-friction coating may include a polymer chemical composition. A light transmission through the coated pharmaceutical package may be greater than or equal to about 55% of a light transmission through an uncoated pharmaceutical package for wavelengths from about 400 nm to about 700 nm. The low-friction coating may have a mass loss of less than about 5% of its mass when heated from a temperature of 150° C. to 350° C. at a ramp rate of about 10° C./minute.
Abstract:
Disclosed are alkali aluminosilicate glasses having unexpected resistance to indentation cracking. The glasses obtain this high resistance as a result of a high level of surface compression accompanied by a shallow depth of layer. The advantaged glasses show greater resistance to radial crack formation from Vickers indentation than glasses with the same compressive stress, but higher depths of layer.
Abstract:
Coated pharmaceutical packages may comprise a glass body formed from a borosilicate glass composition having a Type 1 chemical durability according to USP 660, the glass body having an interior surface and an exterior surface and a wall extending therebetween. A low-friction thermally stable coating having a thickness of ≤1 μm may be positioned on at least a portion of the exterior surface. The low-friction coating may comprise a silane. The portion of the exterior surface of the coated pharmaceutical package may have a coefficient of friction that is at least 20% less than an uncoated pharmaceutical package formed from the same borosilicate glass composition.
Abstract:
Disclosed herein are delamination resistant glass pharmaceutical containers which may include a glass body having a Class HGA1 hydrolytic resistance when tested according to the ISO 720:1985 testing standard. The glass body may have an interior surface and an exterior surface. The interior surface of the glass body does not comprise a boron-rich layer when the glass body is in an as-formed condition. A heat-tolerant coating may be bonded to at least a portion of the exterior surface of the glass body. The heat-tolerant coating may have a coefficient of friction of less than about 0.7 and is thermally stable at a temperature of at least 250° C. for 30 minutes.
Abstract:
One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article retains its average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be prevented by inserting a crack mitigating layer between the glass substrate and the film.
