They are light weighted but have the sturdiness of the alveolar plastic.
They are a cost-effective solution due to the material used which has a great resistance/ protection/ price ratio.
One of their advantages is that they can be produced in smaller quantities and do not require a large MOQ. Also, the production time is short, so these are delivery time-effective solutions.
Being returnable, they can be used for many use cycles, streamlining the costs with packaging and reducing the waste associated with disposable solutions.
