Narrative: Ziploc Bag

The Dow Chemical Co. began manufacturing zip lock bags in 1968, but today the Ziploc brand is marketed by S.C. Johnson & Co.  Polyethylene plastic is melted down to a point in which it is pliable. It is then poured into a very thin mold that is in the shape and size of the bag. The closures on the bags are formed in separate molds out of stronger, thicker plastic. A plastic slider zipper is used to push the lips of the bag closed and to fasten them shut. There is male and a female track. The male track locks into the female track fastening closed and requiring quite a tug to be opened again. The closure is durable enough that you can hold the bag upside down and the contents will not spill out onto the floor.  Low-Density Polyethylene (LDPE). Plastic Recycling Number/Resin ID Code #4. Polyethylene plastic resin is the most commercially used polymer that is available in a large range of flexibilities and densities.  Ziplock plants are located in Bay City, Michigan and in Fresno, California.
 
I acquired this bag from my mother who made me a snack to take back on the train from Hartford, CT to Penn Station, NY in 2010. I washed it out and used it to store costume jewelry that was once my grandmothers. Stephanie Dedes gave me a jewelry box as a gift that same year and I transferred the jewelry to that box. Then I used the Ziplock bag to keep small objects I had been given that I wanted to re-gift at some point.
