Wrap healing is done by keeping your tattoo wrapped in plastic during the entirety of the healing process (you only uncover to wash the tattoo with a small amount of soap and warm water).
The idea is that the plastic helps facilitate healing as it locks in the natural moisture of your skin rather than dissipating as it would during a dry heal.
There’s plenty of similarities between the dry and wrap method – they don’t use moisturizers or product during the tattoo healing process.
I’m not sure that covering up your new tattoo with plastic wrap or an adhesive is that great an idea, given the range of other options available for your fresh tattoo, which is an open wound.
The wrap healing method may be helpful if you have sensitive skin that you aren’t able to leave alone by picking and scratching, or if there are issues relating to your occupation that mean you need to have your skin completely covered and your clothing can’t do an adequate job.
If you’re going to use the wrap healing method and apply cling film or plastic during the healing process it’s imperative that the environment is clean, your wraps are fresh, and that your hands have been thoroughly sanitized each time you remove or apply the bandage, or wash the tattoo.
