Plastic containers have become one of the first choices for food storage due to their lightness, durability, and affordability. However, not all plastic containers are appropriate for storing food. If they aren’t well-chosen, they will affect food safety. So, how to determine which plastic container is suitable for storing food? This article will give you an elaborate analysis.
How to Judge Whether Plastic Containers Are Suitable For Food Storage?
Check the Material Code of the Container
Plastic products usually have a triangular mark on the bottom, and the number represents the material code. The following are several safe plastics suitable for food storage:
- No. 1 PET (polyethylene terephthalate) is commonly used in disposable beverage bottles and is suitable for short-term food storage.
- No. 2 HDPE (high-density polyethylene) is suitable for storing foods such as milk and juice, has good cold resistance, and is suitable for frozen foods.
- No. 4 LDPE (low-density polyethylene) is commonly used in plastic wrap and food bags. It is strong and flexible and suitable for refrigeration.
- No. 5 PP (polypropylene) is the most commonly used food storage plastic. It is strong and heat resistant, so it can be used for microwave heating and long-term storage.
Reminder: Avoid using containers made of materials such as PVC, PS, and other materials that are not clearly marked as 7 (other) to contact food, to prevent harmful substances from migrating into the food.
Whether the “Food Safety” Certification is Marked
When buying plastic containers, please prefer products with the “food safety” certification mark, such as US FDA certification, China GB certification, etc. These marks indicate that the product has passed the formidable testing of the food contact materials.
Heat Resistance and Microwave Suitability
Some plastic containers for food storage might release harmful substances under conditions of high temperature. While purchasing, one should not forget to pay attention to whether the container is marked with words like “Microwave Safe”, especially for those used to heat food.
Recommended Plastic Containers for Food Storage
Refrigerated and Frozen Food Storage
The materials HDPE or LDPE are the best for making plastic boxes that store refrigerated and frozen foods, since they are very resistant to low temperatures and do not crack easily. At the same time, they seal well and prevent spoilage of food effectively.
Heated Food Storage
Because of its better heat resistance, polypropylene (PP) containers are the first choice. It is safe to put containers in a microwave oven for heating besides holding high-temperature foods.
Disposable Food Packaging
If you store food for a short period of time, then plastic containers made from PET material No. 1 are relatively inexpensive and highly practical. Of course, one must consider the aspect that the usage of PET containers should not be repeated or expose them to high temperatures over a long period of time.
Tips to Avoid Potential Risks of Plastic Containers
Regularly Check Whether the Container is Aged or Deformed
Aged, cracked or deformed plastic containers may cause harmful substances to leak out and should not be used.
Avoid Storing High-temperature Greasy Foods for A Long Time
Greasy foods are prone to absorb harmful substances in plastics. It is recommended to use glass or ceramic containers instead.
Choose Colored Plastic Containers with Caution
Some colored plastics may have unsafe pigments added. Transparent or natural containers are preferred.
Environmental Tips: How to Reduce the Impact of Plastics on the Environment
To reduce the burden of plastics on the environment, we can start with the following points:
- Prefer reusable plastic containers, such as storage boxes made of food-grade PP.
- Correctly sort and recycle waste plastics and send them to professional recycling agencies for processing.
- Avoid excessive use of disposable plastics and use more environmentally friendly materials instead.
