Vacuum-packed describes food (and sometimes other goods) sealed in a bag or box with the air sucked out first. Without air, the food goes bad much more slowly, so it keeps longer and can travel further.

It is an adjective and it normally sits before the noun (vacuum-packed rice) or after "be" (the meat is vacuum-packed). English also uses the plain verb: they vacuum-pack the coffee before shipping it. Both are ordinary, everyday words here — this is not a formal or literary term, it is packaging language.

Though actually — the air is never all removed, only most of it. And vacuum-packing slows spoiling; it does not stop it. Vacuum-packed food still has a date on it, and once you open the bag it behaves like any other food and must go in the fridge.

Though actually不過事實上 — the air is never all removed空氣從來不會被完全抽光， only most of it只會抽掉大部分。And vacuum-packing slows spoiling而真空包裝只是讓食物腐壞得比較慢；it does not stop it並不能讓它完全不壞。Vacuum-packed food still has a date on it真空包裝的食物上還是會有日期標示， and once you open the bag一旦你打開袋子 it behaves like any other food它就會跟其他食物一樣 and must go in the fridge必須放進冰箱。
