Marriages used to have string sealed bags with a red strip. I used to find them easy to open and the rrrriiiippp was very satisfying.
They have now changed to rolling the top of the paper sack then sealing it with the outer paper layer. I find this much more difficult to open.
However, the bottom of the bag is stitched and if you touch it every so lightly THE ARSE FALLS OUT THE BOTTOM spreading your feed all over the floor.

Bring back the rippy strip.
