While storing spices, it is essential to ensure the container is air-tight and prevents any contact between the contents and moisture or air. Spices can react with the air’s moisture since they are hygroscopic. Moisture from the air can cause some spice powders to the cake. Spices can lose their flavor when exposed to air because volatile oils evaporate and are lost.

Mold grows when exposed to dampness, spoiling the spices and producing mycotoxins that can be genotoxic, cancerous, or cause food-borne illnesses.

Plastic jars do not provide full-proof air locking mechanism.

The glass jars are prepared using a mixture of sustainably sourced and natural substances and a heating procedure is used to temper the glass, enhancing its strength and toughness. So, glass seasoning jars are relatively more durable with a longer life cycle. 

As for plastic jars, they are subjected to wear and tear after a short period. In addition, they are not durable and can be destroyed after rough usage. As a result, glass jars are the best spice containers because they can withstand constant usage and are relatively hard. 

  • Glass Jars Are Produced in a More Environmental-Friendly Way 

Compared to plastic jars, the production of glass jars generates five times less greenhouse gas emissions and utilizes only half of the fossil fuels than plastic. Glass jars are made from natural, eco-friendly materials that are available in large quantities. However, plastic jars are made from non-renewable materials that are depleting quickly. In addition, the production of plastic jars leaves toxic substances. 

Thus, the best glass spice jars are made in a more environmentally friendly way in comparison to plastic jars. Small glass containers for spices continue to be a reliable and long-lasting option for food storage, while plastic is more prone to melting or discoloration.
