Glass vs PET: Choosing the Right Material for Your CBD Oil

When choosing packaging for CBD oil products, the two most common choices are glass and PET (polyethylene terephthalate) bottles. Each of these materials offers unique benefits and is popular as a result. However, this can make choosing between the two difficult without full knowledge of their benefits and drawbacks. In this blog, we cover the qualities of PET and glass bottles in depth to help you determine which of the two lifestyle product packaging materials is most suitable for your business operations.

How Long Does CBD Oil Last in a Bottle?

CBD oil can last from one to two years in a bottle, though its longevity is also dependent on whether it is stored appropriately. If CBD oil is stored in a cool, dark, and dry place, such as a cupboard or drawer, it is likely to be usable for much longer. This will prevent it from being exposed to high temperatures, UV light, and oxygen, which can quickly cause it to degrade. 

Though its storage conditions are highly important, a significant factor in the longevity of CBD oil is the packaging it’s contained in. The two most common choices for CBD storage are glass bottles and PET bottles, which are each highly suitable options. Below, we delve deeper into these two materials and their distinct attributes, which can make them more or less suitable for different businesses. 

Glass Packaging for CBD Oil

Glass is a highly suitable material for CBD oil and is a popular choice for good reasons. It is an inert material, meaning that it won’t interact chemically with your oil or affect its composition. As a result, glass bottle packaging is a prime choice for preserving the purity and potency of CBD oil over time. Glass is also a fully recyclable material that can be recycled infinitely without loss of quality, making it a completely circular option.

Another key benefit of glass for CBD oil is UV protection. Bottles in darker colours, such as green, blue, and amber glass bottles, filter sunlight out from reaching the bottle’s contents, which can degrade the oil over time. It is worth noting that amber glass is the best colour for filtering UV light, whilst other colours only offer slight protection. Therefore, glass packaging can help to extend the shelf life of CBD oils and maintain product quality. 

However, glass is a heavier and more fragile material, which can lead to increased transport costs and a greater risk of damage if not packaged carefully. It also requires more energy in manufacturing and distribution compared with lighter alternatives.

PET Packaging for CBD Oil

PET (polyethylene terephthalate) bottles are an alternative choice to glass bottles that present a variety of benefits, including durability and efficiency. As PET is a particularly light material, this plastic bottle packaging material can significantly reduce the cost of transport. In addition, it is more impact-resistant than glass, meaning that the risk of breakages during transit is reduced and handling is improved for both consumers and retailers alike.

In comparison to glass, PET requires less energy to create, and when made from recycled PET (rPET), it can have a low carbon footprint in production and transport. PET is one of the most widely recycled plastics globally, and recycled PET can be reprocessed into new packaging or other products as a similarly circular material.

Though, PET does have some disadvantages as a less robust material. PET can come in tinted varieties, though its protection from UV light isn’t as dependable as glass and can be more susceptible to degradation as a result. In a similar sense, PET can degrade over longer periods of time and can therefore become more permeable to oxygen and reduce shelf life.

Glass vs PET for CBD Oil Storage: Which Is Best?

As described above, both glass and PET are highly practical options for storing CBD oil, and which one is best ultimately depends on the priorities of your business.

Glass is an inert material with the option of UV-resistant colours, making it the best choice for the longevity of your product. Though heavier and at some risk of breakage, the premium feel and look that glass provides can convey a high level of quality to customers. However, its increased weight can make it a less preferable choice for some businesses in regard to logistics.

PET is a highly durable material, with its lightness meaning that its transportation is both cheaper and lower emission than glass. Though not reflecting the premium quality of glass, its modern and practical look and feel can be a more suitable choice for various businesses. Its lightweight nature can also make it a more convenient option for customers for day-to-day use.

Neither option is distinctly superior to the other, and both offer many benefits that make them common, beneficial choices for CBD oil storage.
