这两者都属于知识产权领域的相关术语，与软件的许可相关。

“shrink-wrap software licenses”指软件拆封许可，也被称为“拆封合同”、“启封许可证”，是软件销售商现在较为通常采用的通过一种合同对其计算机软件进行保护的方法。在这一许可方法下，软件商将许可条款印在软件外包装上或封条上，因为任何外包装破损的产品顾客是不会采购的，因而保证了顾客能完全地知道这些条款：将“拆封”行为视为对许可这一要约的承诺，就保证了顾客只要拆封，就是达成了许可合同。Shrink-wrap licenses refer to a license associated with a physical product that is effective the moment you take the shrink-wrap off of it. Shrink-wrap is the process of shrinking clear cellophane around a package’s physical box. It used to be far more common for software to be shrink-wrapped but as digital distribution grows, shrink-wrap licenses are on the decline.

而Click-wrap licenses 则是“拆封许可”的一种，因为把在屏幕上的“点击”行为认为是和“拆封”这一行为等效的承诺行为。这一方式主要是在互联网上销售下载软件时采用，购买者在阅读完许可条款后，只有同意并点击了该条款下方的“同意”钮后，软件才会被下载。Click-wrap licenses came into being after shrink-wrap licenses grew in popularity. This is a license agreement that a user digitally agrees to, typically by clicking an “I agree” button. The act of clicking with a computer mouse serves as an understanding of the agreement. The example of agreeing to the Steam terms of service by clicking the “I agree” box is an example of a click-wrap license.

“拆封许可”的其他两种常见方式还包括：1.将软件和许可条款都放在一个封好的透明塑料盒中，用户可看到塑料盒中的许可条款，开盒即为“拆封”。2.将许可条款“融入”到软件中，当软件在装入计算机时，屏幕上显示许可条款，如果购买者不同意这许可条款，安装程序无法继续运行下去，软件是不会被装入计算机的。
