Bisphenol A, or BPA, is a chemical compound commonly used to harden plastics and make them shatterproof. Due to its potential negative health effects, there is a growing interest in BPA-free alternatives. One way to identify if a plastic product is BPA-free is by checking its resin identification code, commonly known as the recycling code. Recycling codes 1, 2, 4, and 5 are generally considered BPA-free, while codes 3 and 6 should be used with caution as they may contain BPA or leach harmful chemicals when heated. Code 7 is a mixed category that requires closer examination. HDPE, or High-Density Polyethylene, is denoted by code 2 and is widely recognised as a safe, BPA-free plastic.

What You'll Learn
HDPE is BPA-free
Bisphenol A, commonly known as BPA, is a chemical used to harden plastics and make them shatterproof. It can mimic estrogen in the human body and act as a potential endocrine disruptor, and studies have linked it to a range of health issues, from reproductive problems to heart disease.
High-Density Polyethylene, or HDPE, is a type of plastic denoted by the recycling code '2'. It is commonly used for milk, detergent, and home cleaning containers. HDPE is regarded as a safe choice for food storage because of its chemical resistance and durability. It is also known for its high performance and high-temperature performance.
To ensure that a plastic product is truly BPA-free, it is important to look for clear markings on the product, including the recycling symbol with the numbers mentioned above. You can also check for safety certification marks from recognized bodies and manufacturer details. When in doubt, request laboratory test reports or verification through certifying bodies.
It is important to note that even BPA-free plastics can break down when exposed to high heat, so it is recommended to avoid microwaving food in plastic containers or using them to store hot liquids.

HDPE is safe for food storage
HDPE, or High-Density Polyethylene, is a safe plastic for food storage. It is identified by the recycling code "2" and is generally considered safe for food contact. The U.S. Food and Drug Administration (FDA) has approved HDPE as a food-safe substance, making it a popular choice in the food packaging industry.
However, it is important to note that not all HDPE containers are food grade. Some HDPE containers may have previously held non-food items, such as chemicals or cleaning agents, and should not be repurposed for food storage due to potential contamination risks. It is crucial to look for the "`food-grade`" label to ensure that an HDPE container is safe for food storage.
While HDPE itself is generally considered safe, recent studies have raised concerns about fluorinated HDPE containers potentially leaching per- and polyfluoroalkyl substances (PFAS) into foods. These substances are often referred to as "forever chemicals" due to their persistence in the environment and the human body. Therefore, it is recommended to use HDPE containers that are not fluorinated to avoid potential exposure to harmful chemicals.
In summary, HDPE is a safe plastic for food storage when it is virgin or properly processed recycled HDPE, and when it has not been contaminated with harmful substances. Its durability, chemical resistance, and FDA approval make it a reliable choice for food packaging and storage. However, it is important to ensure that HDPE containers are labelled as "food-grade" and have not previously held non-food items.

HDPE is used for milk, detergent, and cleaning containers
High-density polyethylene (HDPE) is a versatile thermoplastic polymer made from petroleum. It is one of the most popular plastics in the US and is used for a wide range of applications, including plastic bottles, toys, and containers. HDPE is known for its strength, high-impact resistance, and tensile strength, making it ideal for use in containers that need to hold liquids or withstand weight.
HDPE is commonly used for milk containers, detergent bottles, and cleaning containers. Its high melting point, strength, and resistance to mould, mildew, and rotting make it a suitable material for these applications. HDPE containers can safely carry over a gallon of liquid, and its resistance to chemicals, water, solvents, acids, and detergents further make it a practical choice for these types of containers.
HDPE is also cost-effective and environmentally friendly, as it is easily recyclable. This helps to reduce plastic waste in landfills and decrease plastic production. The durability and weather resistance of HDPE also contribute to its popularity for containers that need to withstand regular use and exposure to varying conditions.
In addition to its functional benefits, HDPE is safe for food and beverage containers. It can be sterilized by boiling and is FDA-approved for food-grade applications. This makes it a trusted material for milk jugs and other food storage containers.
While HDPE is a common choice for milk, detergent, and cleaning containers, there have been efforts to replace it with alternative materials, such as PET bottles, in the case of milk jugs. However, HDPE remains a prevalent and practical option for these types of containers due to its durability, safety, and ease of production and recycling.
