Sack

This page has been revised for the current stable version (41.78.16).

Help by adding any missing content. [edit]

Parts of this page may have been automatically updated to the latest build (42.0.2).

A sack, previously called an empty sand bag, is a container item.

Usage

Container

A sack has poor capacity and encumbrance reduction, and is exceeded by the much more common garbage bag. Unlike the other baggage items, a sack cannot be found with items spawned inside, but its filled variants (excluding the compost bag) can be found throughout the world.

Right-clicking on a full composter while the sack is in the player's hand will display the option to "take compost", upon which the sack will be replaced with a compost bag.

Food within the sack still has a spoilage rating and will still rot, but the entire container can be placed into a freezer and will be preserved like any other food.

In some cases the items would have less encumbrance unpacked, but in some cases they do not, see the table for comparison.

Potato	2.0	12	2.4
Radish	2.0	12	1.2
Strawberries	2.0	16	1.6
Tomato	2.0	12	2.4

Filling with terrain

If the player has a spade shovel, a sack can be filled with dirt, sand, or gravel. To do so, right-click a patch of grass/dirt, sand, or gravel, and select "Take some [Material]". One sack can be filled with 4 tiles of material, and will be turned into the respective material bag.

The dirt bag can be used to spread dirt over a tile, allowing it to be tilled for farming.
The sand bag is used in a carpentry recipe, constructing a bulletproof sandbag wall.
The gravel bag is also used in a carpentry recipe, constructing a bulletproof gravel bag wall.

Any bag can be emptied onto a tile, changing it to the contained material. Once the bag is emptied, the sack will be returned to the player.

Location

The loot distributions can be found in the table(s) below.

Effective chance calculations are based off of default 'apocalypse' loot settings, with no luck modifier, and average zombie density. The higher the density of zombies in an area, the higher the effective chance of an item spawning. Chance is also influenced by the lucky and unlucky traits. Duplicate entries do exist, but have been removed for clarity.

Trivia

While some mods add the ability to store food in a sack as a single item, similar to the loot item, this is not a vanilla feature of the game.
Note that in build 42, the sacks of vegetables/fruit items are being removed, as build 42 will have a different, more immersive, means of spawning the containers of vegetables and fruit in the produce warehouses.
