What You'll Learn

Plastic bins may contain plasticizers that smell
Plastic storage bins are known to give off a strong plastic smell, which can be off-putting to users. While the plastic itself may not be the source of the odour, it is likely that plasticizers used in the production process are the culprits. Plasticizers are chemical additives used to increase the flexibility and durability of plastic. However, certain types of plasticizers can impart a distinct odour to the final product.
One user reported that their plastic storage bins emitted a strong chemical smell, which transferred to the contents stored within, including clothing and hunting gear. This suggests that the plasticizers used in those particular bins were not adequately odourless or had degraded over time, leading to the release of volatile organic compounds (VOCs). VOCs are known to have strong odours and can be harmful to human health.
To mitigate the smell, some users recommend airing out the plastic bins before use by leaving them outside in the fresh air for several days or weeks. Sunlight, in particular, can help to accelerate the off-gassing process, reducing the intensity of the smell. Additionally, users can try placing dryer sheets, baking soda, or earth scent wafers inside the bins to absorb and neutralise odours.
It is worth noting that not all plastics are created equal in terms of odour. For example, LDPE plastic typically doesn't contain plasticizers and is less likely to have a strong smell. Choosing plastic storage bins made from different types of plastic or opting for alternative materials like wood or fabric can help users avoid the issue of unpleasant odours altogether.
While the smell from plastic bins may be undesirable, it is important to remember that the presence of plasticizers does not necessarily indicate a health risk. However, for individuals sensitive to chemicals or with specific health concerns, it may be advisable to select storage options that do not rely on strong-smelling plastics. Overall, understanding the potential for plastic bins to contain odorous plasticizers can help consumers make informed choices to ensure a pleasant and safe storage experience.

Odours are trapped by plastic bins
Plastic storage bins can sometimes retain odours due to their material composition and airtight nature. The plastic may emit a chemical smell, known as off-gassing, which can be noticeable when the bins are first purchased and used. This odour can transfer to the contents stored within, such as clothing, linens, and other fabrics.
The airtight nature of plastic storage bins can trap existing odours, especially if the items stored inside have a strong smell. This can be a particular issue if the bins are not properly cleaned or dried before use. For example, if hunting gear is placed inside without being adequately aired out, the plastic bin may trap and retain the odour of sweat.
Additionally, plastic storage bins can contribute to the growth of mould or mildew if there is moisture present. This can result in a musty smell that is trapped within the bin and affects the stored items. To prevent this, it is recommended to use silica gel packets or other moisture-absorbing materials inside the bins to maintain dryness.
It is worth noting that not all plastic bins are created equal when it comes to odour retention. Some types of plastic, such as polyethylene, may be less likely to emit strong odours. However, even within the same type of plastic, variations exist depending on the specific manufacturing process and the use of additives or plasticizers.
To mitigate the issue of odours being trapped by plastic bins, several solutions can be employed. One approach is to air out the bins before use by leaving them outside or in a well-ventilated area for several days to allow any existing odours to dissipate. Another tactic is to use odour absorbers or neutralizers, such as dryer sheets, baking soda, or earth scent wafers, placed inside the bins to counteract unpleasant smells. Additionally, drilling holes in the lids of the bins can improve airflow and reduce the trapping of odours.

Plastic bins smell due to off-gassing of VOCs
Plastic storage bins often emit a strong, unpleasant odour due to the off-gassing of volatile organic compounds (VOCs). This occurs when the plastic bin releases chemical gases, which can be further exacerbated by high temperatures. The odour can be particularly noticeable when the bins are first purchased, with some people recommending that new bins are left outside for several weeks to allow the smell to dissipate before they are used.
The off-gassing of VOCs from plastic storage bins can cause the contents stored within to absorb the chemical smell. This is particularly true for fabrics, which can take on a strong chemical odour if stored in plastic bins for long periods. Clothing and other fabrics can become imbued with the plastic smell, requiring them to be washed before use.
To mitigate the issue of off-gassing VOCs, some people recommend airing out the plastic bins before use. This can involve leaving the bins outside in fresh air and sunlight, which can help to accelerate the off-gassing process and reduce the intensity of the smell. Additionally, leaving the bins open and empty for several days before use can help reduce the concentration of VOCs present.
Another method to reduce the impact of off-gassing VOCs is to use odour absorbers. For example, placing dryer sheets, silica packets, or baking soda inside the bins can help to neutralise the chemical smell. Alternatively, spraying the bins with a mixture of vinegar and water, or wiping them with denatured alcohol, can also help to eliminate the odour.

Plastic bins smell when they are new
Plastic storage bins often emit a strong odour, which can be attributed to various factors. One of the primary reasons is the presence of plasticizers, commonly found in polyethylene bins. Plasticizers are chemical additives that provide flexibility and durability to the plastic. However, certain types of plasticizers can impart a distinct odour to the bins. This odour can be especially noticeable when the bins are new and have not been exposed to air yet.
The off-gassing of volatile organic compounds (VOCs) is another contributing factor to the smell of new plastic storage bins. VOCs are chemicals that vaporize at room temperature, and they are commonly found in plastics during the manufacturing process. When the plastic bins are first opened, these VOCs are released, resulting in a strong chemical smell. This odour can be mitigated by airing out the bins before use.
Additionally, the residue from fabric softeners or detergents stored in the bins can also contribute to the odour. Over time, these residues can degrade and emit a chemical-like smell. This is more likely to occur if the bins are not regularly cleaned or if they are exposed to moisture, which can accelerate the degradation process.
To address the issue of smelly plastic storage bins, several measures can be taken. Firstly, it is recommended to air out the bins before using them. Leaving them outside in the fresh air for a few days or weeks can help dissipate the odour. Sunlight, in particular, can aid in off-gassing the smell.
Another suggestion is to use odour absorbers or neutralizers. Placing items such as dryer sheets, silica packets, or baking soda inside the bins can help absorb and neutralize any unpleasant smells. Additionally, earth scent wafers can be effective in masking the odour, although they may not eliminate it completely.
For more persistent odours, cleaning the bins with a vinegar and water mixture or denatured alcohol can be beneficial. Spraying or wiping down the inside of the bins with these solutions and allowing them to air dry in the sun can help eliminate the smell. Regular cleaning and maintenance of the plastic storage bins can also prevent the build-up of odours over time.

Airing plastic bins outside can reduce the smell
Plastic storage bins are a convenient way to store items, but they can sometimes emit an unpleasant odour, which can be absorbed by the items stored within. This smell is likely due to plasticizers in the polyethylene bins, rather than polyethylene itself. One effective way to reduce this smell is to air the plastic bins outside before using them for storage.
Airing plastic bins outdoors allows fresh air to circulate within the bins, helping to dissipate the odour. It is recommended to leave the bins outside for several days to a few weeks, depending on the severity of the smell. During this time, the bins should be left open, with their lids removed, to maximise air circulation.
Exposing the bins to sunlight can also aid in reducing the odour. Sunlight can help to break down and neutralise the volatile organic compounds (VOCs) responsible for the smell, a process known as off-gassing. Off-gassing can also occur in the absence of sunlight, but it may take longer.
By allowing the bins to air outside, the plastic smell can dissipate, reducing the likelihood of it transferring to stored items. It is important to note that some bins may have stronger smells than others, and additional measures may be necessary for particularly odorous bins. However, airing them outside is a crucial first step in reducing the smell and ensuring your stored items remain fresh and odour-free.
In addition to airing the bins outside, there are other measures that can be taken to reduce the smell. For example, dryer sheets can be placed inside the bins to help mask the odour and keep the contents smelling pleasant. Silica gel packets can also be useful in absorbing any excess moisture that may contribute to the development of mould or mildew, which can cause unpleasant smells. These additional measures can be employed after airing the bins outside to further reduce any remaining odours.
