比较级前为什么有不定冠词

Because it is vacuumpacked, it has a much longer shelf life than regular beef.

请问这个比较级前面为什么要用一个不定冠词？

句子中的不定冠词是修饰比较级后面的名词的——a much longer shelf life——这里的 shelf life 本义是指“放在架子上的时间”，即“保存限期”，也就是“保质期”的意思。句意：

Because it is vacuumpacked, it has a much longer shelf life than regular beef. 因为是真空包装，它的保质期比一般的牛肉要长的多。
