First-aid kits can be expensive, especially weatherproof kits. So why not save a little and create your own weatherproof first-aid kits with your EcoVac vacuum sealer or chamber sealer bags? If you really want to make a first-aid kit that can withstand rain, sleet, and snow storms then gather your supplies and place them in a vacuum sealer bag. Pro tip, be careful when sealing your items, especially when it comes to stuff that doesn’t take kindly to moisture. A great solution is to seal your medical supplies with a small desiccant silica pack to absorb any moisture than may be inside the bag. Next, take everything out of your regular first-aid kit and separate them. Put your scissors in one sealable bag, sterile gauze in another, painkiller meds in the other, and so on. Note, if you put any medication in your bag that it’s a good idea to write their expiration date on the exterior of your vacuum sealer bag so you know when it is time to put in fresh supplies. Make sure that every object is sterile before placing them in the sealable bags. Vacuum the air out of each bag, place packs in your cooler or cosmetics bag and, voila, you now have a hospital-grade first-aid kit. What I like to do, is leave a small gap in the upper part of the bag and cut a small slit in the edge of the bag without breaking the vacuum seal, in cases I need open the pack fast.
