Some of you have noticed that even sneezing in the direction of the container can break it apart, if your spells are extra destructive then you may not be able to get the majority of containers enemies drop unless one pixel of it survives and you're lucky enough to spot it before it despawns.

Here's what you can do:
Go to: \Steam\steamapps\workshop\content\881100\2006631283\files\data\entities\items\pickup
Then open health_container.xml in notepad
(I prefer using Notepad++, makes looking through scripts and code easier)

find
"<PhysicsImageShapeComponent
body_id="1"
centered="1"
image_file="mods/health_container/files/health_container.png"
material="ice_glass_b2" >
</PhysicsImageShapeComponent>"

Change the material to whatever you want. Noita wiki provides ID's for all materials in the game. I changed it to brickwork with "templebrick_static", but you can go with something between in terms of durability if you'd like. Have fun with your new less fragile health containers, maybe lower their drop chance further since you don't need to compensate for them breaking anymore.
