Commercial canning is done on a far greater scale than home canning. Other than that commercial canning includes methods not used in the home such as pasteurization and ionizing radiation. One more big difference is the types of containers used in commercial canning include tin-lined steel cans that require an opener to slice the lid from the can, and laminate vacuum pouches used for fruit drinks and other liquids. Home canning uses primarily glass jars with 2-piece lids. Finally, more chemicals are used in commercial canning than in home canning.
It is not safe to reuse commercial canning jars for home canning. The glass in home canning jars is thicker than in commercial jars and they are created specifically to work with 2-piece lids. It is also not advisable to use very old canning jars.
