All food will break down overtime as micro organisms go to work. At normal room temperature, the bacteria thrive, and depending on the food, they will multiply quickly to dangerous levels. By freezing the food, the micro organisms don't die, but they will multiply at much slower rates, meaning the food will keep longer.

You put it in the freezer and wait.
well, yes. the reason being that any food that needs to be put in a freezer is intended to be stored away for later use. being that it's vacuum packed is just an additional step taken to preserve the food longer because you prevent the frozen food from "freezer-burned"--moisture,air, bacteria getting into the contents--all these things that would naturally degrade food products.
wrap in freezer bags and freeze up to 6 months

It is not recommended to store food in tin cans in the freezer as the expansion of food during freezing can cause the cans to bulge or burst. It is better to use freezer-safe containers or bags to store food in the freezer.
A food saver is used to vacuum package foods for cooking or re-heating later. a food saver works by vacuuming out the air in the package-thereby eliminating air to spoil foods or allow freezer burn.
