Ziploc bags (or "potches" as you referred to them) are incredibly versatile and have a wide range of uses, mainly due to their resealable, airtight, and often durable nature.

Here are the most common and some creative uses:

1. Food Storage and Preservation (Most Common):

* Storing fresh food: Keeping fruits, vegetables, cheeses, and deli meats fresh in the fridge.

* Freezing: Protecting food from freezer burn (e.g., meat, prepared meals, smoothie ingredients, sauces, cookie dough).

* Portion control: Dividing bulk food items or meals into individual portions.

* Leftovers: Storing and reheating leftovers (some types are microwave/oven safe).

* Marinating: Placing meat and marinade in a bag for even coating and easy cleanup.

* Packing lunches/snacks: Sandwiches, chips, crackers, etc., for on-the-go.

2. Organization and Travel:

* Toiletries/Liquids: Complying with TSA guidelines for carrying liquids in carry-on luggage, and preventing leaks onto clothes.

* Organizing small items: Separating socks, underwear, and other small clothing items inside a suitcase.

* Wet/Dirty Items: Storing wet swimsuits, dirty clothes, or muddy shoes separate from clean items.

* Electronics protection: Keeping phones, cameras, or other electronics dry and free from sand/dust (e.g., at the beach or outdoors).

* Document protection: Storing passports, maps, or other important papers to keep them dry and organized.

3. Home and Household Uses:

* DIY Ice Pack: Filling a bag with ice (or a wet sponge, then freezing) for a flexible, mess-free ice pack.

* Organization: Sorting and storing small items like craft supplies (beads, buttons, thread), hardware (nails, screws), or office supplies.

* DIY Piping Bag: Cutting a small hole in one corner and filling it with frosting for cake decorating.

* Cleaning: Filling a bag with vinegar and securing it over a faucet or showerhead to soak and clean mineral buildup.

* Temporary Trash/Waste Bag: Using them for small trash or waste items while traveling or outdoors.
