English: package和packaging在意义和用法上有什么区别？

以下的英文解释都来自谷歌

Packaging is the technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use.
从上面这段文字理解packaging的话，主要指的是包装，和包装技术 -- 用在商品的分发，仓储，销售和使用。 还可以指代包装从设计到最后生产的过程。

A packet, originally a package of letters or dispatches, is a small package
or bundle: a packet of gems. A parcel is an object or objects wrapped
up to form a single, small bundle: a parcel containing two dresses.
而Package从上面这段解释来看，主要是用来表达包裹，一包xx东西，其中一包的包就是package，等同于例句中的bundle, parcel
