Right from the start, glass has a cost disadvantage compared to plastic: glass is more expensive to produce. The manufacturing processes for both plastic and glass packaging are overall quite similar, as both involve heating the material and then using molds to give it its desired shape and thickness. Where glass production differs from plastic is in the amount of energy required to manufacture each bottle.
Depending on its specifications, glass melts at between 1400°C to 1600°C. Meanwhile, plastic melts at a much lower temperature, at around only 170°C. This means plastic requires significantly less energy to shape and manufacture.
Further, advancements in molding technologies continue to lower plastics production costs, as bottles can be shaped using less heat and more quickly, requiring even less energy. Taken as a whole, plastic production is a more efficient process than that of glass.
Working with a reputable plastic manufacturer ensures products are efficiently produced and costs will be reduced. This makes plastic an optimal packaging solution for you and the consumer.
Shipping is a complex, time consuming, and often expensive process. There is a lot that occurs throughout the shipping process:

This multi-stage process leaves a lot of room for potential issues, including product loss. The more often glass bottles must be handled, whether during the shipping or filling process, the higher the potential for damage to occur. Glass can easily shatter. This poses a safety concern, but it also means a cut into your bottom line.
Shaking and bumping are common during the shipping process. This leaves glass vulnerable to chipping, cracking, and shattering. On the other hand, plastic is more durable and resists cracking and breakage.

Glass is comparatively heavier than plastic. Consider the following measurements: glass has a density of approximately 2.6 g/cm3 compared to HDPE plastic, which is around 0.9 g/cm3. This makes glass almost three times heavier than plastic of the same size. In addition, plastic containers can be made thinner than glass bottles, further reducing their weight.
Let’s compare a 2 oz. glass jar and a 2 oz. HDPE plastic jar as an example. We’ll assume that both jars have the same dimensions and a 53mm neck opening. A 2 oz. glass jar with a 53mm neck opening will weigh around 82.2 grams. In comparison, the 2 oz. plastic jar weighs only around 13.0 grams. This means it would take 6.3 plastic jars to equal the weight of a single glass jar. This difference is substantial – especially when ordering pallets of bottles in bulk.
In this example, you can see just how much the weight differential between plastic and glass can impact transportation costs and ultimately your bottom line.
The right material will depend on the needs of your organization. Factors often include packaging safety, cost considerations, and the product itself. If managing costs is at the top of your list, then plastics make a compelling case.
At Drug Plastics, we invest in our customers’ success – we understand there is more to a relationship than just the financial transaction of buying packaging. When you work with us, you can rest easy knowing that we can help guide you in making informed packaging decisions. Ready to get started?
