4 Plastics That Are Best To Use For Food Storage Containers

When it comes to food storage containers, plastic is one of the most popular materials to use. There are many different reasons why people tend to opt for a plastic container box for food. For one, plastic containers are very durable. They do not crack or break easily even when you toss or push them. They are design to endure tough situations, so they usually last long.

But did you know that plastic also comes in different types? There are several kinds of plastic containers out there, and some are safer for food and water storage than the others. Hence, it is very important to consider what type of plastic is used for your food containers. Read on to find out 4 of the best and safest types of plastic used for food storage containers.

1. PET

Polyethylene terephthalate or PET is a chemically stable polyester that is used in manufacturing many different products. It is a clear, lightweight, and strong plastic that is excellent for storing food and water even for the long term. What is better about PET as a food storage solution is that it is also 100% recyclable. Therefore, it is a good option if you are conscious about the environment.

PET containers have incredible oxygen barrier qualities and can be utilised with oxygen absorbers for storing bulk dry goods. The sealed containers’ low oxygen content protects the stored food from insects and helps maintain product quality. PET containers are best suitable for products that are rotated regularly, while still delivering numerous years of storage capability.

Here are the food items and beverages commonly stored in PET containers:

  • Juices
  • Soft drinks
  • Pickles
  • Peanut butter
  • Salad dressing


Low density polyethylene (LDPE) is a soft, lightweight, and flexible thermoplastic material that is noted for its toughness, low temperature flexibility, and corrosion resistance. It is considered less toxic compared to the other types of plastic and is relatively safe to use for storing food and water. Unlike PET, the products made with LDPE plastic are usually reusable but not always recyclable.

Here are the kinds of food containers commonly made with LDPE:

  • Bread packaging
  • Squeezable bottles for honey and mustard
  • Frozen food bags


High density polyethylene (HDPE) is a thermoplastic made from ethane and is considered as one of the most versatile plastic materials out there. It is weather-resistant, impact-resistant, and long lasting. In comparison to other plastics, HDPE has proven itself at delivering a strong surface durability. Like PET, HDPE is also extremely easy to recycle, so it is another great option for the eco-conscious folks. 

Here are the food or beverage containers commonly made with HDPE:

  • Milk containers
  • Juice containers
  • Chocolate syrup containers
  • Vinegar bottles
  • Squeeze butter bottles

4. PP

Polypropylene (PP) is a widely used thermoplastic made from the combination of propylene monomers. It is lightweight and tough but can still be flexible as well. Unlike many other kinds of plastic, PP has a high heat resistance, so the possibility of chemicals leaching into PP containers is low. As such, it serves as an effective barrier against chemicals, moisture, and grease. PP is a great choice for food storage containers because it can hold up well in hot environments.

Here are the food or beverage storage items commonly manufactured with the use of PP:

  • Deli meat containers
  • Potato chip bags
  • Yogurt containers
  • Margarine tubs
  • Plastic bottle tops
  • Medicine bottles


Many people are unaware that plastic comes in several different types. It is important to know what these plastics are to determine whether or not your plastic food containers you use at home or buy from the grocery and elsewhere are effective and safe for storing food items and beverages. For effective, safe, and long-lasting food storage solutions, PET, LDPE, HDPE, and PP are the best plastics you should opt for.
