Person 2: Aahh yes. It can be used to cut the plastic wrap your using!

Person 1: Exactly. But also it doesnt work at all.

So I was researching what is the best way to freeze foods and came across this neat article defining if plastic wrap or aluminum foil is better.  Ultimately, aluminum foil is better only if you buy the post consumer recycled brand and if you reuse each piece a minimum of six times.  With this in mind, I dug deeper and found that reusable silicone freezer bags are going to be the best for freezing if you need an airtight seal with a non-liquid.

Upsides of silicone:

1) The base of silicone comes from quartz, a plentiful resource.

2) Very inert, especially compared to plastic, so won't leach harmful chemicals into your food or the environment.

3) Can be recycled.

Downsides of silicone:

1) Very hard to recycle.  You will have to find a special recycle center and often you have to pay to have it taken.

2) The hydrocarbons used to make silicone usually come from petroleum or natural gas.

3) Very inert, so it will take it as long as plastic to break down in the environment if it's not properly recycled.
