But if you&rsquo;re packaging food, that approach usually fails. Here&rsquo;s why. Food isn&rsquo;t uniform. Some parts are wetter than others, and that moisture changes how the packaging absorbs heat. If you just blast the whole thing with the same amount of energy, you&rsquo;re going to end up with a mess—either cold spots where the seal didn&rsquo;t take, or burnt film where it got too hot.</p>
