Plastiseal is a very useful Medical Item used to effectively treat some common injuries.


Plastiseal is used to treat Bleeding and Burns. When applied, it will reduce the affliction strength by 40 and 50 respectively over a period of 10 seconds. This will only affect the limb on which the Plastiseal is applied. Applying to burned limbs will restore vitality quickly. Bleeding does not reduce Vitality appreciably, but instead, Plastiseal is effective at reducing the rate of Bloodloss that Bleeding causes. Plastiseal is one of the few Medical Item to only apply its effects to a single limb. It functions similarly to Bandages and Antibiotic Glue.

Plastiseal treats both regular Burns and Acid Burns.

Bleeding is caused by many attacks from Creatures and hostile Humans. Burns are caused by Fires, failing electrical repairs, various weapons such as Flamers and Ancient Weapons, Explosives, Radiation Sickness, and some Creature attacks, such as Fractal Guardians and Watchers.


Like all Medical Items, Plastiseal can be applied via the Health GUI (Default Key H). See this page for more information on usage.

Plastiseal cannot be loaded into a Syringe Gun, though it can be swung by hand.

Even though Plastiseal can be applied by hand on another character, this is not recommended, as targeting a specific limb is difficult, and the effects will only be applied to whichever limb is hit.

Plastiseal is not used in any crafting recipes.


Plastiseal is a Medical Item that is used to effectively treat some of the most common Afflictions: Bleeding and Burns. An uncommon property of Plastiseal is that it only applies its effects to a single limb. This generally means that several Plastiseal are necessary to fully treat a character, and in general it is advised for Medics to carry more than a single stack at all times. Non-medics may also consider carrying some, due to their fairly low Medical Skill requirement and general effectiveness.

Since high levels of Bleeding can drain Vitality quickly, Plastiseal are extremely useful at stabilizing a downed character. If a downed crewmate is not being actively attacked by a Creature, Bleeding is often the most pressing threat to their life, and is the cause of the most preventable deaths. Plastiseal should be used fairly generously in the case of catastrophic Bleeding, as it is both reasonably cheap and has no side effects on use.

Plastiseal is effective for most non-emergency and some emergency cases, and is also quite cheap to craft. The more advanced Antibiotic Glue functions similarly to Plastiseal, however while it treats Bleeding much more effectively and Burns nearly as effectively, it is more expensive, and since it is also limb-specific, much of its healing power is often wasted. It is, however, the best treatment for Infected Wounds, and so some should be kept on hand for that purpose. A single Plastiseal per limb is sufficient for most cases, though two may be used for very severe injuries.

Since both Bleeding and Burns heal themselves over time (as well as Bloodloss), if a character is not in immediate danger, simply waiting can be an acceptable substitute to Plastiseal, especially in the case of very minor wounds, which are is not recommended to waste Plastiseals on. The Health Scanner HUD will show the affliction strength, and this may be used to judge whether using Plastiseal is necessary. It should be noted however that the Health Scanner HUD sums the damage over the entire character, so this may not give an accurate picture. The affliction strength bar should be referred to instead - this will appear under each Affliction when clicking on a limb in the Health GUI - one Plastiseal will heal 50% of this bar for burns and 40% for bleeding.


  • Prior to (3rd Anniversary Update), crafting yielded 2 Plastiseal for each Bandage, against the current 1 to 1 crafting recipe. Nonetheless, it is still a recommended upgrade.
