Assuming that the question means to ask about reusing the lids on mason jars, which you should not use for freezing, the answer is, that technically, you can reuse the metal rings that tighten down but you should avoid reusing the metal discs which actually make the seal. These are basically coated with a gasket material and if they bend, warp, or become uneven, the seal may not be good. Most people do reuse them, but you are supposed to buy new ones for each new use, while reusing the same jars.

Suppose you've bought some jam in a glass jar, and then when it's empty you clean it out and hang on to the jar to keep other stuff in - that's reuse.

Why do lids pop again after the canning process?
Two-piece vacuum lids are made to release pressure by venting air from the jar after processing and upon cooling. When the lid does not vent, pressure build-up warps the lids. There are several possible reasons for lids to buckle when in a hot water bath or pressure canner:If the screw bands are applied too tightly it causes buckling immediately after processing.It you boil the lids (should be heated but not boiled) it softens the sealing compound too much, and results in a premature seal.Food spoilage due to incorrect processing produces gases inside the jar that force the lid to buckle or unseal.To prevent buckled lids: Process foods using up-to-date guidelines, prepare lids according to manufacturer's instructions, and apply bands just until a point of resistance is met - fingertip tight.
