APPX file format was introduced along with Windows 8 i Windows Phone 8.1 operating systems as a file distibution format for applications available on Windows Store. Application package is a container-type file that follows Open Packing Convention (OPC) standard describing hierarchical structure for storing data and other resources in ZIP archive format.
APPX file is an archive that contains application in its final form, ready for distribution and installation. Submitting APPX package to Windows Store requires user to pick a name for the app, attach details regarding sale model and list of available functions. Each submitted package needs to undergo a security and compatibility testing procedure.
Streamlined distribution of packages between computers, tablets, and phones – devices that vary in their characteristics – is the main goal that lead to creation of APPX file format. Traditional applications were based on clunky installers that were notorious for causing problems on mobile systems. APPX was designed to address this problem and make installing apps less of a hassle.
APPX file format was updated into more advenced version – APPXUPLOAD. Upgraded version introduced new functionality – option to send debugging information for the app.
Maximum size of APPX file is 2GB.

There can be more reasons which determine that you are not able to open the APPX file (apart from the lack of the proper application installed).
First - the APPX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the APPX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the APPX file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the APPX file has not been completed and it cannot be opened properly).
