Food Storage
It is important to store food so animals don't get to your food. One, you don't want to have animals steal or contaminate your food. Two, you don't want animals, especially bears, coming in to camp for your food. Three, it's bad for the animals to get used to you and your food.

The following information includes common products and practices used by backpackers.
These products and practices may violate food handling practices or expose the handler or consumer to pathogens or chemicals that may be unhealthy.
Basic Rules
NEVER sleep with food in your tent! Mice will chew through your tent to get to your food. Worse - a bear may do the same. You don't want a hungry bear in your tent.
Rules
Hang food 12 feet up in a tree, 6 feet away from the trunk and 200 feet from camp.
When needed or required - use a bear canister. These make for a great seat in your kitchen
If car, bike, wagon or canoe camping, buckets or barrels can protect against animals smaller than you
Hang Bags
The traditional way of storing food is hanging it from a tree branch. Use the PCT method, since bears in the Pacific Northwest have figured out how to take down bags tied down to trunks of trees.
You don't need a fancy bag, but fancy options are available:
Zpacks Bagging Kit - Dyneema
Hilltop Packs - Dyneema

You'll need 50'
Ideally Dyneema Composite Fabric (laminated Ultra High Molecular Weight Polyethylene)

Hydrophobic
Static
Slick stuff
Notch Acculine - 2.2mm Throw Line - Dyneema

Bear Canisters
These can often be rented where you register for the trail or by an outdoor outfitters
Many places require the use of a bear canister - if it is required, use it.
Example:
Bear Bag
"Bearproof" bags don't allow bears to rip into your food bag. This is a lightweight option to a bear canister.
NOTE
Rodents can still chew through these
Smells still permeate through fabric
Bears can and will still chew bag and crush everything in it
Consider using a smellproof bag inside bear bag to reduce animal interest
Example:
Barrels and Buckets
These are great waterproof options for storing food and it protecting against rodents. Use for canoe, bike and car camping.
Square buckets can be used an panniers on bikes.
5-Gallong Buckets with Screw lids
Smell Proofing
Smellproofing will reduce interest in your bag. Some hikers use these as stand alone system without hanging or bear proofing - this technique is NOT recommended.
Example:
