Glass vials are known for safety and sustainability. People prefer them to plastic vials owing to environmental concerns. Yet, indicating one of them is better would be missing the point. Alternatively, both kinds of vials are effective and serve depending on the requirement.
Both of them have a similar process as well. After determining the raw materials, they are washed, sterilized, dried, filled, re-sterilized and sent to the packing area. In manufacturing plastic vials, there is no process for washing or sterilization.
Quality of the glass vials is possibly the best reason why they are considered more preferable. They have a purity of structure, that is, the contents never react with the glass. This purity attribute is absent in the plastic bottles.
Glasses are made from natural raw materials, making the vials safer. In the pharmaceutical industry, the lack of additional chemicals can be crucial. The ability to stand a stable temperature for relatively a long time is remarkable. Unlike plastic vials, these glass products do not bulge or shrink with the change of temperature.
Depending on the requirement, manufacturers can adjust the thickness of the vials. It is simply not possible to store some medicines, but in glass containers. This is apparent even in other industry as well, most notably in the beverage market.
In addition, we can recycle the glass products. The feature of having just one material allows us to recycle the glasses repeatedly. The amazing solution is that they never lost their quality or the purity.
Experts speculate more than 90 per cent of vials in the pharmaceutical industry are made of glass.
On the other hand, there are certain why the plastic vials are more advantageous. They are known for their impact strength. Their low weight makes the whole process of packaging and delivering effortless.
These vials are more cost effective. Unlike those of glass, these vials require no sterilization or drying and hence, it takes lesser time to produce them as well.
Depending on a manufacturer’s specification, these vials can be reversible bottles with dual-purpose cap, snap cap vials and those with child-resistant caps. Among these kinds, the first reversible bottles are the most common.
Most of the raw materials used in making plastic vials are environmentally friendly. Manufacturers use materials such as Polyethylene and Polypropylene.
To conclude, both the vials are equally crucial in the pharmaceutical industry. Manufacturers can serve depending on the requirements.
