Just need help to solve this mystery.
My company packs Spirulina powder in 1.0kg jars.After filling there is around 20% of vacant space in jar.
Due to Spirulina being fine powder we were receiving lots of customer complaints of powder leaking out of lids etc.
To eliminate this issue we started induction sealing jars.
Goods news,customer complaints dropped significantly but bad news my Spirulina jars started collapsing /sucked inwards.
Has anyone experienced this type of issue and know how to resolve it.
I really want to keep induction sealing jars.
Thanks in advance.
