There are many instances where I open food packets, but am unable to close it airtight after taking out some content. Food packets means, packet of noodles, biscuits, snacks, chips, etc. This moisturizes the food and reduces the quality and its crispiness.
I am not interested in using a rubber band as it becomes sticky over the time if not used. Also I do not want to transfer it to airtight bottles/containers as it consumes so much space in the cupboard. Since there are many plastic bags, I am not interested in buying plastic sealers for all of those. I am looking for hacks to close or seal the plastic covers airtight.
I usually twist and fold the opening of bag but over time it automatically gets loosened.
