Plastic containers are a common storage solution for many people, but they may not be the best option for outdoor use. Plastic is not a stable material and can break down over time, especially when exposed to heat. This breakdown can cause the plastic to release chemicals and microplastics into the food or items stored within. While the impact of microplastics on human health is still being studied, it is known that they are present in human organs, breast milk, and the placenta. Additionally, some of the chemicals found in plastic, such as BPA, phthalates, and PFAS, have the potential to cause cancer or other health issues. The complex chemistry involved in plastic production makes it challenging to know exactly which chemicals are present in plastic containers. Heat can also cause plastic containers to deform, affecting their functionality and durability. Therefore, it is essential to consider the potential risks associated with using outdoor plastic storage containers in high-temperature environments.

What You'll Learn
Plastic containers can deform in hot temperatures
Plastic containers are commonly used to store, freeze, heat, and transport food. However, they can deform when exposed to hot temperatures. This deformation occurs due to the expansion of air and the weakening of the plastic molecules. When hot water is placed in a plastic container, the air inside expands, and some of it is forced out. If the container is closed before the air cools, it will take up less space, creating a vacuum effect that can cause the container to deform. Additionally, heat can break down the chemical bonds in plastic, potentially releasing chemicals into the contents.
The complex chemistry involved in plastic production makes it challenging to identify all the chemicals present in plastic food containers. However, researchers have identified hundreds of "chemicals of concern" that may be used in products that come into contact with food. These chemicals have the potential to migrate into food and drinks, especially when exposed to heat. Oily and fatty foods can further increase the migration of chemicals from plastic containers.
To avoid potential health risks associated with chemical exposure, it is recommended to use glass or ceramic containers for heating food in a microwave or storing hot food. Glass is considered a safer alternative as it is non-reactive, stain-resistant, and suitable for both hot and cold items. Additionally, opting for reusable options can help reduce the widespread ingestion of microplastics, which have been found in various parts of the human body.
While plastic containers may be convenient for storage, they are not always the best choice for certain items. For example, raw meats should be stored in airtight, sealable containers, and glass is often preferred over plastic to prevent cross-contamination. Leather items should be stored in cool, dry places to prevent mould or mildew, and silica gel packets can be used to absorb moisture. Photographs are also susceptible to damage from heat or moisture, and specialised containers are recommended for their long-term storage.
Overall, it is important to be cautious when using plastic containers, especially for food storage and heating. While plastic may be a cost-effective solution, the potential risks associated with chemical exposure and the release of microplastics should be considered. By opting for alternative materials and reducing the use of single-use plastics, individuals can minimise their exposure to potentially harmful chemicals and contribute to a healthier environment.

Chemicals in plastic containers can leach into food or drink
Plastic containers are a convenient and cost-effective solution for food storage, but concerns have been raised about the potential health risks associated with chemicals leaching into food or drinks. While the industry maintains that their containers are safe, experts caution that heat can accelerate the breakdown of plastic and increase the migration of chemicals into the contents.
Plastic containers are made from various substances, including polyethylene and polypropylene, and the complex chemistry involved makes it challenging to identify all the chemicals present. When exposed to heat, such as in a microwave or dishwasher, these plastics can break down, potentially releasing unknown chemicals into food and drinks. This process is more pronounced when plastic is old or has been repeatedly used and washed.
Studies have shown that thousands of substances used in plastic products can "leach" or "migrate" into food and drinks. While manufacturers and food safety authorities assert that the levels are too low to pose a risk to human health, some scientists argue for more stringent enforcement of regulations. The Food Standards Agency (FSA), for example, has regulations prohibiting manufacturers from using materials that release harmful levels of chemicals into food. However, the effectiveness of these rules has been questioned due to a perceived lack of data and transparency.
To minimize the potential risks associated with chemical migration, some experts recommend opting for glass or ceramic containers, especially for hot food and when heating food in a microwave. Oily and fatty foods should also be avoided in plastic containers, as they can break down the plastic over time and increase the risk of chemical contamination.
Additionally, it is important to avoid single-use plastics, such as plastic water bottles, and reduce the use of plastic wrap, especially when heating food or when the food has a high fat content. These small changes can help decrease the potential health risks associated with chemical exposure from plastic containers.

Oily and fatty foods can break down plastic
Plastic is not a completely stable material and can break down over time, potentially releasing trace amounts of chemicals into food. Heat, for example, from a microwave or dishwasher, can cause plastic to break down and leach unknown chemicals into food and drinks. This is because heat helps to break the chemical bonds in plastic. Even plastic containers labelled "safe" for the microwave and dishwasher may not be safe, as experts caution that heat and plastic don't mix well.
The complex chemistry needed to make plastics makes it hard to know exactly what other chemicals are found in plastic food containers. However, studies have shown that some of the thousands of substances used to make plastic products can "leach" or "migrate" into the food and drinks we consume. These chemicals can enter our blood and tissue quickly, and the harmful effects may be cumulative, increasing health risks.
To avoid the potential health risks associated with chemicals in plastic, it is recommended to use glass or ceramic containers for storing oily and fatty foods.

Plastic containers are not suitable for storing leather items
Plastic containers are not ideal for storing leather items. Leather is a natural material that needs to "breathe". Plastic containers trap excess moisture, creating a breeding ground for mould and mildew, which can cause cracks in leather items. Leather stored in plastic containers is also susceptible to discolouration and warping.
The lack of air circulation in plastic containers can cause leather to become stiff and discoloured. Leather is sensitive to light, particularly sunlight, which can cause it to fade and weaken over time. The ultraviolet (UV) rays in sunlight degrade the natural oils in leather, leading to discolouration, drying, and eventual cracking. Therefore, leather items should be stored in a well-ventilated area with good air circulation.
Leather items should be stored in breathable storage solutions, such as dust bags for smaller items and durable clothing bags for larger items. Acid-free archival boxes are also recommended for smaller leather goods as they prevent dust build-up while allowing for gentle air circulation. Open shelving units made of wood are ideal for storing leather bags as they ensure airflow and prevent them from becoming cramped or misshapen.
Additionally, plastic containers are known to contain chemicals that can potentially be released and transferred into the items stored within them. These chemicals can be especially harmful to leather items, causing discolouration and deterioration.

Plastic containers are not suitable for storing photographs
Plastic containers are not the best option for storing photographs. While plastic containers are readily available and cost-effective, they may not be the safest option for storing photographs, especially over long periods.
Firstly, plastic containers are not ideal for storing photographs due to the potential presence of harmful chemicals. Studies have shown that some of the thousands of substances used to make plastic products can 'leach' or 'migrate' into the items stored within. Although manufacturers and food safety authorities claim that the levels of chemical migration are too low to pose a risk to human health, there is a lack of data to support this, especially when plastic containers are used to store hot items or are heated themselves. For example, when exposed to heat, polyethylene and polypropylene can break down, releasing unknown chemicals. This is also true for water bottles left in the sun. As photographs are often printed on paper, which can absorb chemicals, storing them in plastic containers may expose them to these unknown chemicals, potentially causing discolouration or other damage over time.
Secondly, plastic containers are not recommended for storing photographs due to the potential for heat damage. Heat can cause the plastic to break down and release chemicals, as mentioned above, but it can also damage the items stored within. High temperatures can cause photographs to stick together, fade, or become distorted. This is especially true if the plastic container is not ventilated, as the heat and moisture can become trapped inside, creating the perfect environment for mould or mildew to develop, which could damage the photographs.
Lastly, plastic containers are not as durable as other storage options and may not protect photographs from physical damage. Plastic breaks down over time and is susceptible to scratches and discolouration, which can weaken the structure. This means that plastic containers may not protect photographs from external elements or physical damage, especially if the containers are exposed to extreme temperatures or sunlight.
Overall, while plastic containers are convenient and affordable, they may not be the best choice for storing photographs. Alternative options, such as paper or cardboard boxes, are recommended by experts to ensure the longevity of photographs. These alternatives are time-tested and less likely to expose photographs to unknown chemicals or extreme temperatures, increasing the likelihood that the photographs will remain in good condition for future generations to enjoy.
