Due to the increasing tightened regulatory demands of the Pharmaceutical Industry, containers have to meet the following requirements:
Glass has many advantages when compared with other packaging materials. It is traditionally held in high regard when discussing barrier properties, but depending on the chemical composition of the product contained, the quality of the tubing, and the converting process, the inner glass surface can be harmed by delamination, resulting in flakes barely visible to the naked eye.
Recent advances in the field of glass processing technology allow for the development of Type I glass vials that can withstand the delamination process. The region near the bottom of Schott DC (delamination controlled) vials particularly show a unique surface homogeneity and chemical stability. As a result, the liability to delaminate is improved. Schott DC vials comply with all current standards, including the ones mentioned above.
The new line of vials produced by Schott ensure that a number of benefits are provided to companies seeking to improve the quality of the packaging in which their drugs are shipped.
The new processing technique maintains glass surface homogeneity, reducing the risk of delamination and ensuring formulae remain as pristine as possible.
Conventional vials can be replaced by DC vials that feature delamination control without the need to revalidate the pharmaceutical product.
Production quality is routinely checked by the Schott's Delamination Quicktest. The routinely conducted Quicktest monitors product quality and certifies that Schott DC vials do not exceed the set sodium limit, ensuring that the delamination tendency is reduced.
Filled with a 15 percent potassium chloride solution or a 10 percent sodium thiosulfate solution, DC vials remained stable even after being exposed to a temperature of 60 degrees Celsius for twelve weeks.
Na and B depletion
Volatile components like boron and sodium evaporate while the bottom of the glass vial is being formed. As the production process continues, these substances produce inhomogeneous spots on the glass surface that are generally more susceptible to delamination.
Product recalls of numerous injectables over the last several years, have cost pharmaceutical and partnered packaging firms upwards of 50 million USD per recall.
SCHOTT is the first manufacturer capable of determining the risk of delamination based on threshold values, and then monitoring these values over the course of manufacturing. To achieve this, the company developed the patented SCHOTT Delamination Quicktest.
