Sandwich bags made by Haplast can be used to freeze food successfully. Sandwich bags (also called Ziplock bags) are the best choice for freezing food as they are strong, will seal well and keep your food safely frozen. Freeze pre-made sandwiches for school or work, fruit, or cake to keep it fresh.
5 Tips to Freeze Your Food in Sandwich Bags
1. Remove all of the air
Remove all the air from the ziplock bag before placing it in the freezer. This can be as simply as squeezing the air from the top and sealing the bag quickly. When using a Ziplock bag quickly run your fingers over the zip to seal it.
2. Seal it well
Sealing the zipper bag well before placing it in the freezer is important to keep your food protected from freezer burn or collecting ice and water on the surface. Ziplock bags make it easy as they come built in with a sealing mechanism.
3. Label it correctly
Labelling food frozen in sandwich bags is incredibly important. Once food goes in your freezer it can be hard to remember what is in each bag so write the date and the type of food on the bag. Many sandwich bags will even come with a white area which is perfect for labelling your food.
4. Avoid salad ingredients
Avoid freezing ingredients in sandwich bags that are fresh that contain excess water. It might be tempting to freeze a healthy salad sandwich but this will not work. Ingredients such as lettuce will turn to mush when frozen so stick to basic sandwich ingredients such as cheese, peanut butter and jelly.
5. Check the food for freezer burn
Make sure you use a good quality sandwich bag or freezer bag to seal your food. Freezer-safe sandwich bags are the best choice to freeze your food as they will be thicker and are designed to seal tightly. This will keep air out, prevent freezer burn and keep your food fresher for longer.
