When it comes to food packaging, not all plastics are created equal. The Food and Drug Administration (FDA) has established guidelines for safe, direct contact with food, and for a plastic to be considered food grade, it must meet these stringent safety requirements. This means that the plastic must be able to withstand the environment it will be used in without undergoing any physical changes. For example, if a plastic conveyor belt transports food through an oven, it must be able to withstand those temperatures without changing. FDA compliant means that a material meets all of the FDA's guidelines for safe, direct contact with food. Many plastics are only FDA-compliant and food-safe in their virgin (unrecycled) state, but some, like PET, can be recycled many times and remain FDA-approved for food contact.

FDA-approved plastics are safe for direct food contact
The Food and Drug Administration (FDA) has established guidelines for safe, direct contact with food. For a material to be FDA compliant, it must meet all of the FDA's guidelines for safe, direct contact with food. It must be able to withstand the environment it will be used in. For example, if a plastic conveyor belt transports food through an oven, it must not undergo any physical changes when exposed to high temperatures.
To be considered "food grade," a plastic must meet the safety requirements of the types of food it comes into contact with. Some foods, such as tomato sauce, are acidic and might leach chemicals from non-compliant plastics. Most of the plastic jars and beverage containers in homes are made from PET plastic. This clear, strong, and lightweight plastic repels microorganisms and doesn't corrode, making it ideal for food and beverage storage.
Recycled PET is an FDA-approved plastic for food contact. It also repels microorganisms and doesn't corrode, making it an ideal material for food and beverage contact and storage. Polypropylene is often used for single-serve containers like yoghurt cups and is also microwave safe and nonvolatile, meaning it will not react with any type of stored food, whether it is acidic, basic, or liquid.
HDPE is very strong, impact-resistant, weather-resistant, and long-lasting. It is used for milk jugs, butter containers, cereal box liners, and thicker food storage buckets. Although HDPE is recyclable, it may become unsafe if recycled too many times. LDPE is less rigid, making it perfect for plastic bags, squeeze bottles, and six-pack rings. In its virgin state, LDPE is chemically resistant, repels microorganisms, and does not leach toxins when used to store foods.

Recycled plastics can be used for food packaging
The use of recycled plastics in food packaging is a complex issue that involves balancing sustainability goals with food safety considerations. While some advocate for the use of recycled plastics in packaging to reduce the environmental impact of plastic waste, there are concerns about potential chemical hazards and contamination.
The U.S. Food and Drug Administration (FDA) plays a crucial role in evaluating the safety of recycled plastics for food contact. The FDA has approved at least 347 voluntary manufacturer applications for food contact materials made with recycled plastic. However, researchers have criticized the FDA's approval process as being lax and not adequately addressing the potential risks associated with chemical mixtures in recycled plastics.
One of the main concerns with using recycled plastics in food packaging is the potential presence of contaminants. Hazardous chemicals can be introduced during the recycling process, and these chemicals may migrate into food products, posing health risks to consumers. To address this, the FDA considers each proposed use of recycled plastic on a case-by-case basis and provides guidance to manufacturers on evaluating the purity of recycled plastics for food-contact applications.
Additionally, the type of plastic and its intended use are important factors. For example, recycled PET (polyethylene terephthalate) is widely used in bottles and has been deemed suitable for food contact by the FDA. On the other hand, recycled PP (polypropylene) and HDPE (high-density polyethylene) are often used for non-food-contact applications like disposable tableware and packaging.
While recycled plastics can be used for food packaging in certain cases, it is crucial to prioritize consumer safety and adhere to strict guidelines to ensure that any potential contaminants are removed during the recycling process. The FDA provides resources and regulations to assist manufacturers in making informed decisions about the safe use of recycled plastics in food packaging.

FDA compliance means a plastic meets FDA guidelines
FDA compliance means that a plastic meets the FDA's guidelines for safe, direct contact with food and is essentially an official way of saying a material is "food grade". Not just any material can make the FDA-approved list for food contact, but several types of plastic in our refrigerators and pantries do make the cut. To be considered "food grade", a plastic must meet the safety requirements of the types of food it comes into contact with. For example, some foods, such as tomato sauce, are acidic and might leach chemicals from non-compliant plastics.
Many plastics are only FDA-compliant and food-safe in their virgin (unrecycled) state. However, recycled PET is an FDA-approved plastic for food contact. It also repels microorganisms and doesn't corrode, making it an ideal material for food and beverage contact and storage. Polypropylene is most often used for single-serve containers like yoghurt cups, but also shows up in reusable containers that can store leftovers. On top of being one of the FDA-approved food contact materials, it's microwave-safe and non-volatile, meaning it will not react with any type of food you store in it, whether it's acidic, basic, or liquid.
HDPE is very strong, which is why a plastic jug weighing 2 ounces can easily contain a gallon of milk. It is impact-resistant, weather-resistant, and long-lasting. In addition to milk jugs, HDPE is also used to make butter containers, cereal box liners, and thicker food storage buckets. Although HDPE is recyclable, it is possible for it to become unsafe if it's recycled too many times. That's why the FDA reviews HDPE on a case-by-case basis. Similar to HDPE, LDPE tends to be less rigid, which makes it perfect for plastic bags, squeeze bottles, six-pack rings, and more. In its virgin state, LDPE is chemically resistant, repels microorganisms, and doesn't leach toxins when used to store foods.
To be FDA-compliant, a material must be able to withstand the environment it will be used in. For example, if a plastic conveyor belt transports food through an extremely hot oven for cooking, it must not undergo any physical changes when exposed to those temperatures.

FDA-approved plastics are safe for food storage
The Food and Drug Administration (FDA) was created to set standards for the safe production and storage of food, beverages, and drugs. FDA-approved plastics are those that meet the FDA's stringent guidelines for safe, direct contact with food. In other words, they are "food grade".
To be FDA-compliant, a plastic must be able to withstand the environment in which it will be used. For example, a plastic conveyor belt that transports food through a hot oven must not undergo any physical changes when exposed to high temperatures. FDA-approved plastics are also non-reactive, meaning they do not leach chemical properties into food when in use.
There are several types of FDA-approved plastics that are safe for food storage. These include HDPE, LDPE, PC, PETE, and PP. HDPE is the most common household plastic and is used to make beverage bottles, butter containers, and food storage buckets. LDPE is similar but tends to be less rigid, making it perfect for squeeze bottles or plastic film. Recycled PET is another FDA-approved plastic for food contact. It repels microorganisms and doesn't corrode, making it ideal for food and beverage contact and long-term storage. Polypropylene (PP) is also FDA-approved and is often used for single-serve containers like yogurt cups. It is microwave-safe, has high heat resistance, and is nonvolatile, meaning it will not react with any type of food, whether acidic, basic, or liquid.
While some food-grade plastics are deemed safe for food storage, it is important to note that not every food-grade material is food-safe. For example, a plastic storage container manufactured for dry cereal may not be safe for storing hot soup. Heat can break down the chemical bonds of the plastic, causing toxins to contaminate the food. Therefore, it is crucial to use plastics according to their intended purpose and follow specific guidelines related to food storage, temperature, and recycling.

Some plastics are only FDA-compliant in their virgin state
The Food and Drug Administration (FDA) has established guidelines for safe, direct contact with food. For a plastic to be deemed "FDA compliant", it must meet all of the FDA's guidelines for safe, direct contact with food. It is essentially an official way of saying a material is "food grade".
To be FDA compliant, a material must be able to withstand the environment it will be used in. For example, if a plastic conveyor belt transports food through an extremely hot oven for cooking, it must not undergo any physical changes when exposed to those temperatures.
While many plastics are FDA-compliant, some are only compliant in their virgin (unrecycled) state. For example, PET plastic is a clear, strong, and lightweight plastic that repels microorganisms and doesn't corrode, making it an ideal material for food and beverage storage, even for the long term. However, it is important to note that not all plastics are created equal, and some plastics may only be FDA-compliant in certain applications or under certain conditions. For instance, HDPE is a strong and impact-resistant plastic often used for milk jugs and butter containers. Although HDPE is recyclable, it can become unsafe if it is recycled too many times, which is why the FDA reviews it on a case-by-case basis.
In addition to the plastic material, the FDA also considers the manufacturing process and any additives that may be present. For example, there are concerns about bisphenol A (BPA) present in polycarbonate resin, which can affect the normal function of hormones if leached into food or drink products. Overall, it is important to specify FDA-compliant material at the time of order to ensure that the appropriate material is provided for the intended application.
