What about milk cartons? Milk cartons are cardboard with a wax or plastic coating. By the time they have been used for milk and washed for use in the freezer, some of the coating is gone so they may no longer be moisture and air tight.
It is hard to seal milk cartons so that they are air tight. They do give shape to packages making them easier to stack than in bags. Probably the best uses of milk cartons are with a plastic bag inside which can be closed and for freezing fish in water. The water (ice) keeps out moisture and air. What about coffee cans? Getting an air tight seal may be the major problem. Plastic lids with a double lip that fits down both inside and outside the top edge of the can are desirable. Freezer or masking tape can be used to keep out air. Some coffee cans have a tendency to rust around the seams. A plastic bag liner would eliminate this concern. Storing dry foods such as cookies, nuts, or popcorn may be the best use for the ordinary coffee can used as is.
What about reusing plastic bags? It’s quite alright to use plastic bags again if you are-sure they do not have holes in them when we buy them. They aren’t suitable for use in the freezer.
