I know its a minor fix, but honestly, the tin foil textures on the food containers has always kind of annoyed me on the cs777. 
*if you would like to revert to the original textures, please make a copy of the original textures and store it elsewhere, I am not responsible if you can't get the original textures back
It's pretty easy to install just follow these steps:

1. Locate the 777's texture directory, inisde the community folder
777 300ER: captainsim-aircraft-m773\SimObjects\Airplanes\CS_B777-300ER_GE115B\TEXTURE
777 200ER: captainsim-aircraft-m772\SimObjects\Airplanes\CS_B777-200ER_GE90B\TEXTURE

2. Copy and paste "CS777_S_10_D.png.dds" into the texture directory. When prompted to overwrite the file click yes. (If you would like to revert to the original textures, please make a copy of the original textures and store it elsewhere)

3. Enjoy the styrofoam texture on the food containers in your captainsim 777!

*A PNG version of the texture file is included if you would like to edit it. If you would like your edited version included in the next update, just PM me on Flightsim.to to let me know!
