Your system looks interesting. Sorry for all the questions, but I'd like to know more:

Is vacuum sealing for preservation or only compactedness? If for preserving, how long will the food keep?

How much for the initial setup (vacuum-sealer and bags) and the cost of replacement bags?

Are they safe for microwaving? There have been recent reports about the safety of microwaving certain plastics. I used to reuse (once) 16 and 32 oz yogurt or cottage cheese tubs then dump them after nuking a meal. This type of plastic is now known to be unsafe . https://www.health.harvard.edu/fhg/u...ate0706a.shtml

Thanks in advance.
