Plastic or glass when storing honey?

If pure honey is stored for a long time, it is not suitable to use plastic bottles, because plastic will produce plasticizers over time, and the sealing effect is not good. The solution is best to use a refrigerator to store them. In supermarkets, Honey is basically syrup when it is stored in plastic bottles.

Considering its transparent beauty, good chemical stability, no pollution to the contents, high temperature resistance, and can not affect the quality of honey, glass bottles are chosen for long-term storage.

The honey is put in a plastic bottle. After a few days, the plastic bottle swelled because it is full of gas and would volatilize because the weather is not so cold, but the plastic bottle feel a little softer and the honey appears white. Foam is the reaction of honey with plastic bottles.
