Provided is a PET bottle preform in which delamination is suppressed and a method for the production of the preform. An anchor layer containing a polyester-based urethane resin is formed on an outer surface of the preform.

A plastic container includes a base portion, a sidewall portion, a neck portion, a barrier coating applied to at least portions of an outer surface of sidewall portion, and a protective layer printed or sprayed on at least portions of the barrier coating. In embodiments, the barrier coating may be applied via dip coating, spray coating, and/or drop on demand ink jetting (e.g., ink jet printing). In embodiments, a protective layer, or protective coating formulation, may be provided as part of a base coat, such as a clear coat, or as an additive in a base coat ink formulation and/or may be part of an ink jet decoration process.

Powder coating compositions, particularly metal packaging powder coating compositions, coated metal substrates, and methods; wherein the powder coating compositions include powder polymer particles comprising a polymer having a number average molecular weight of at least 2000 Daltons, wherein the powder polymer particles have a particle size distribution having a D50 of less than 25 microns; and, in certain embodiments, one or more charge control agents in contact with the powder polymer particles.

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 <660> 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.

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.

A method of reducing static charge of a plastic container is provided. The method includes providing a PECVD coating of SiCOH, SiO.sub.x or SiOH to an external support surface of the container. The PECVD coating reduces static charge of the container compared to a reference container that is essentially identical to the container except that the reference container is uncoated.

This disclosure provides new containers, preforms, methods, and designs for small and light-weight carbonated beverage packaging that provide surprisingly improved carbonation retention and greater shelf life, while still achieving light weight. This disclosure is particularly drawn to small PET containers for carbonated beverages, for example less than or about 400 mL, and methods and designs for their fabrication that attain unexpectedly good carbonation retention and shelf life.

Provided is a PET bottle preform in which delamination is suppressed and a method for the production of the preform. An anchor layer containing a polyester-based urethane resin is formed on an outer surface of the preform.

A glass container includes a hollow body of a glass material. The hollow body surrounds an inner volume and has a lower end and an upper end. A container opening extends through the upper end into the inner volume. The hollow body further includes a container collar surrounding the container opening, a container neck, a container shoulder, a container body, a container bottom closing the lower end, and an inner container surface facing the inner volume and an outer container surface facing away from the inner volume. The glass container is coated on its outer container surface at least partially with a coating and the coated glass container has an increased scratch resistance with respect to a contact of the glass container with at least one further glass container.

Coated pharmaceutical packages are disclosed. The coated pharmaceutical packages may include a glass body comprising a first surface and a second surface opposite the first surface. The glass body may be a glass container formed from a borosilicate glass composition and the first surface is an exterior surface of the glass container. A low-friction coating may be positioned on at least a portion of the first surface of the glass body. In embodiments, the low-friction coating may be a fluoropolymer.
