Where Vial Precision Meets Pharma Packaging Expertise | Kapoor Glass

Pharmaceutical packaging is a critical component of protecting medicines during manufacturing, storage, transport, and delivery into use. A lyophilized vial is an essential element of formulations that are subjected to freeze-drying because the container must be robust enough to withstand rigorous temperature excursions and the rational processes carried out in the pharmaceutical laboratory. The selection of pharmaceutical glass containers demands meticulous inspection of material quality, dimensional control, finish, cosmetic appearance, and interaction with filling and finishing equipment. Kapoor Glass offers pharmaceutical tubular vials in Type 1 neutral borosilicate glass that meet this portfolio of requirements for a broad spectrum of applications including lyophilized products.

Lyophilization: Freeze-Drying Pharmaceutical lyophilization is employed in the manufacture of pharmaceuticals in cases where removing the water content from the product while controlled freezing and drying can assist the formation of a more stable final formulation. During lyophilization, the pharmaceutical vial becomes integral to a tightly controlled manufacturing process. The fill volume, such as the shape, the distribution of the glass, the base, and the size of the dimensions and the interaction between the fill and the vacuum auto-fill and lyophilization equipment can all influence.

This guidance for pharmaceutical vial manufacturing is especially useful for companies filling and finishing containers on high-speed lines. Variations in the dimensions of the vials can interfere with the ability of the containers to handle being transported along automated lines. In addition, Kapoor Glass employs inline camera system to monitor important dimensional tolerances and cosmetic finishes, and the use of Statistical Process Control to maintain regular manufacturing practices reduces variation in tolerances.

Kapoor Glass is a renowned vials manufacturer as well as pharmaceutical tubular vials manufactured in Type 1 neutral borosilicate glass. These pharmaceutical tubular vials are offered in clear and amber tubular vials from 1 ml to 50 ml with specifications such as penicillin neck vials, screw neck vials, and tablet vials. The company also offers various finish options, blowback vial configurations, ceramic printing, surface treatment as well as lyophilization specific solutions.

LYOsafe, a lyophilization-specific flat-bottom vial, is one of a range of specialty products from Kapoor Glass. The company says that the design "aims to optimize freeze dryer performance and minimize breakages" during pharmaceutical lyophilization. Online control of base geometry and glass distribution, combined with various online and offline measurements, helps minimize wastage and process downtime for lyophilizers. These packaging design and inspection factors can be a key aspect of package choice for the manufacturers of complex lyophilizer systems.

The selection between clear and amber glass may also be dictated by the nature of the pharmaceutical product. Clear glass allows the contents of the container to be seen, and this can be advantageous for visual inspection and while handling the product. An amber glass may be used where protection from light exposure is needed by the product formulation and packaging specification. Kapoor Glass's production portfolio encompassesflint/clearand amber type 1 neutral borosilicate tubular vials, in which pharmaceutical companies can make their selection based on the specific needs of the product formulation.

Industry 4.0 (making things digital) in manufacturing technology helps further with the consistency of your glass packaging. Kapoor Glass claims that its vial manufacturing lines utilize automation to limit glass-to-glass as well as glass-to-metal contact, which aids in the cosmetic finish of the vials while also helping to keep production conditions within a controlled range. To prevent issues with your glass packaging while in process, vials are transferred and visually inspected automatically by camera inspection systems. Automated camera inspection can assist with catching dimensional and visual characteristics throughout the process rather than relying solely on human inspection after production.

As with pharmaceutical secondary packaging, clean handling and packaging conditions are just as relevant to pharmaceutical primary packaging. In terms of primary packaging, Kapoor Glass confirms that the vial packing process occurs in a clean controlled environment and confirms that its vials meet the requirements of the European, US and Japanese Pharmacopoeia. This information can be helpful for pharmaceutical companies choosing packaging suppliers and determining procurement criteria, though final appropriateness should be confirmed to the needs of the individual product and manufacturing process.

Vial finish & closure system A one size fits all approach to packaging may not be suitable for every pharmaceutical. The closure configuration of a vial may be influenced by the filling line, the stopper, sealing method and the application for which the product will be used. At Kapoor Glass, we have 13 mm and 20 mm finishes, penicillin neck and screw neck vial options, blowback vial options for European and American markets and more.

Surface treatment considerations may also be applicable to pharmaceutical filling and finishing manufacturing. Kapoor Glass provides the ammonium sulphate treatment to remove alkalinity from the glass surface, and the external siliconisation to provide protection against scratch removal and jamming in the wash/fill/finish operations. These examples help to show that a choice of vial extends well beyond size and aesthetic considerations: material properties, surface, finish, treatment, inspection and manufacturing consistent.

In the context of a new product development or an existing system review, it can be helpful to state requirements prior to choosing an end vial. Considerations to address include fill volume, headspace, formulation and container–closure sensitivity, light protection, stopper compatibility, size of finish, freeze drying requirements, equipment considerations, storage conditions and transport. A technical packaging supplier can assist in determining which available configuration meets those requirements.

Kapoor Glass has over 60 years' experience in glass manufacture and provides pharmaceutical ampoules, tubular vials, cartridges and laboratory glass products. The capabilities of its vial manufacturing include automated production, camera-based inspection, tight dimensions and special options for pharmaceutical packs. This capability might be of interest for organizations considering a packaging vendor with knowledge of the needs of contemporary pharmaceutical manufacturing.
