  1. UNDERSTANDING FREEZER-SAFE PLASTICS

  2. Plastic products are of different types and varieties, depending on the material used to manufacture the finished product. And today, we use plastic products for different purposes, from storing food to freezing it in the freezer. However, not all types of plastic are freezer-safe. Thus, if you plan to store and freeze food in your plastic container and want to know if it's safe for your food, then this PPT is for you.

  3. HOW TO IDENTIFY FREEZER-SAFE PLASTICS? Different types of plastics are given a resin identification code to differentiate between their type and quality. So, when it comes to freezer storage, plastics marked with the codes 2 (HDPE), 4 (LDPE), 5 (PP), and sometimes 1 (PET or PETE) are generally considered safe. • HDPE, 2 (High-Density Polyethylene) This is a durable type of plastic that is used for storing milk jugs, freezer bags, and even detergent bottles. This type of plastic doesn’t crack at low temperatures, thus making it an ideal type of plastic for freezer storage. • LDPE, 4 (Low-Density Polyethylene) This type of plastic is used in grocery bags, squeezable bottles, and plastic wraps. It is resistant to low temperatures and also suitable for short-term freezer use. • PP, 5 (Polypropylene) This is a sturdy type of plastic and is used in making food containers like yogurt, sauces, and some types of food takeout containers as well. This type of plastic is microwave-safe as well. • PET or PETE (Polyethylene Terephthalate) Although this plastic is safe for freezing, it can become brittle at low temperatures. If you are using PET plastic containers, then check for freezer-safe labels on them.

  4. PRACTICAL TIPS FOR FREEZER STORAGE • Don’t fill to the brim If you are storing food or liquid in your plastic container, then don’t fill it to the brim. Try to leave some space at the top to avoid leaks or breakage when they expand upon freezing. • Use a vacuum sealer When you vacuum seal your food, you remove air from inside and prevent it from getting freezer burn. This helps to maintain the overall quality of your food. • Thaw safely When you need to thaw your food, place it in the freezer to thaw it gradually. Don't directly place it in the microwave, as it can lead to uneven results.

  5. Final Thoughts It is a good idea to understand which plastic containers are freezer-safe to ensure you don't damage your freezer or your container and also don't spoil the quality of your food. Choosing the right type of freezer-safe plastic containers can go a long way in ensuring your food remains fresh inside the freezer for a long time.
