Well, whether you want to reuse the bags or not, it is your choice. However, if you choose to reuse ziplock bags, here’s a complete guide and some tips for you!

Meet Ziplock Bags

In the past, zipper storage bags were what are ziplock bags called. Moreover, the name “ziplock” comes from how you can seal the top of the bag reclosable with a locking device, which is an adhesive zipper or zip lock slider. These bags first came onto the market in 1960. Back then, the bags were meant to be used for boiling. Yes, you read it right, for boiling! How?

So, basically, we were supposed to submerge them with the food contents inside in boiling water on the stovetop. The goal? It was simply to heat the food.

However, polyethylene plastic, which is the material of ziplock bags, comes with a softening point of approximately 96 degrees Celcius. Thus, you should not boil the bags at temperatures up to this level. Otherwise, it can cause the material to break down and leach microscopic plastic particles into the food items. Instead, you should consider the maximum temperature for a Ziplock bag, which is around 80 degrees Celsius.

Later on, these reusable ziplock bags ended up being one of the most popular plastic bag types. The zipper bag material contains a thin and flexible polyethylene resin. Meanwhile, the best uses for ziplock mylar bags are to store different products, including milk jugs, egg cartons, and other items.
