Plastic garment bags are a convenient and quick solution for storing clothes. However, they may not be the best option for preserving your garments in the long term. While they protect against dust and dirt, plastic bags can trap moisture, especially in hot and humid conditions, leading to mould and mildew issues. Additionally, the lack of breathability can cause discolouration and fading, especially in delicate fabrics like silk and cotton. The choice of storage method depends on the climate, duration, and type of clothing. While plastic bags are suitable for short-term use, such as transporting clothes, breathable alternatives like cotton or mesh nylon bags are recommended for long-term storage to maintain the condition and quality of your garments.

What You'll Learn

Plastic bags can cause discolouration and fading
Plastic garment bags can cause discolouration and fading of clothes over time. The plastic material prevents the fabric from breathing, leading to yellowing and weakening of fibres. This is especially true for natural fabrics like cotton, silk, and leather. Butylated hydroxytoluene (BHT), a chemical antioxidant found in some plastic bags, reacts with impurities in the air and moisture to form a yellow pigment that transfers to the fabric, causing unsightly stains.
The lack of ventilation and trapped moisture in plastic bags can also contribute to mould and mildew growth, further damaging the fabric. This is more likely to occur in hot and humid storage conditions. Additionally, the odour of plastic can permeate the clothing, causing an unpleasant smell that may be difficult to remove.
To prevent discolouration and fading, it is recommended to avoid using plastic garment bags for long-term storage. Instead, opt for breathable materials such as cotton or meshed nylon covers, which allow air circulation and protect clothing from dust and dirt. It is also crucial to store garments in a well-ventilated area, away from direct sunlight, and to ensure that the storage space is not too cramped, allowing air to circulate around the clothes.
While plastic garment bags may be convenient for short-term storage or transportation, they should not be used for long periods. By choosing suitable storage materials and creating optimal storage conditions, you can help maintain the colour and quality of your clothes over time.
In summary, plastic garment bags can indeed cause discolouration and fading of clothes due to the lack of breathability, the presence of chemicals like BHT, and the potential for trapped moisture and odours. To protect your garments, it is best to opt for breathable alternative materials and ensure proper ventilation in storage areas.

They can trap moisture, leading to mould and mildew
Plastic garment bags are not ideal for storing clothes, especially in the long term. They can trap moisture, which can lead to mould and mildew, causing severe and irreversible damage to your garments.
Plastic bags are not breathable, and when used to store clothes in hot and humid conditions, they can trap moisture, which then gets absorbed into your garments. This can cause mould and mildew to develop, which can ruin your clothes.
Mould and mildew thrive in damp, humid environments, and the lack of airflow in plastic bags only exacerbates the problem. The trapped moisture has nowhere to go and is absorbed into the fabric of your clothes, providing the perfect conditions for mould and mildew to grow.
This is especially true if your wardrobe or storage area has little to no ventilation. The effects of using plastic bags in these conditions can be detrimental, and you may not realise the damage until the next season when you go to reach for your favourite garment.
To prevent mould and mildew from damaging your clothes, it is best to avoid using plastic bags for long-term storage. Instead, opt for breathable garment bags made from natural textiles such as cotton, or use airtight plastic bins with lids to protect your clothes from moisture.

Plastic bags are not breathable, impacting air circulation
Plastic garment bags are not breathable, which impacts air circulation and can cause severe and irreversible damage to your clothes. When using these types of bags, no fresh air can circulate in and around your garments, especially in cramped spaces or spaces that lack airflow.
The lack of breathability in plastic bags can lead to trapped moisture, which can be absorbed into your stored garments, causing damage. This is especially true in hot and humid conditions, where the moisture has nowhere to go except into your clothes. This can result in issues such as mould and mildew, which can severely damage your garments, particularly those made of suede and leather.
Additionally, the lack of air circulation can cause discolouration and fading, especially in cotton, silk, and other delicate fabrics. Butylated hydroxytoluene (BHT), a chemical antioxidant found in some plastic dry cleaning bags, can react with impurities in the air and moisture to form a yellow pigment that transfers to the fabric, causing unsightly yellow spots.
To protect your clothes, it is recommended to use breathable garment bags made of organic natural textiles, such as cotton. These bags allow air to circulate and help prevent moisture build-up, discolouration, and other damage that can be caused by non-breathable plastic bags.
In summary, plastic garment bags' lack of breathability and impact on air circulation can have detrimental effects on your clothes, leading to moisture absorption, mould and mildew growth, discolouration, and other types of damage. Switching to breathable garment bags made of natural textiles is a better option for protecting and prolonging the life of your garments.

They can cause damage to natural fibres and leather
Plastic garment bags can cause damage to natural fibres and leather. They trap moisture, particularly in hot and humid conditions, which can then be absorbed into the stored garments. This can cause mould and mildew to form, which is especially harmful to suede and leather jackets.
Plastic bags also prevent air circulation, which is necessary to nourish and rejuvenate fabric fibres. This lack of ventilation can lead to discolouration and fading, especially in cotton, silk, and other delicate fabrics. Butylated hydroxytoluene (BHT), a chemical antioxidant found in some plastic bags, can react with impurities in the air and moisture to form a yellow pigment that transfers to the fabric.
Vacuum-sealed plastic storage bags are also not recommended for clothing made from natural fibres or leather. The compression of the bags can damage certain materials, such as silk and cashmere, and cause permanent creases and wrinkles. Leather items may also be cracked by the compression of vacuum seal bags, resulting in irrevocable damage.
To avoid damage to natural fibres and leather, it is best to store garments in a well-ventilated area, protect them from environmental elements, and use natural fabric garment covers, such as those made from 100% cotton.

Plastic bags are harmful to the environment
Plastic garment bags can indeed be harmful to clothes, especially in the long term. However, they are useful for protecting garments from dust and dirt during short-term storage and transportation.
Firstly, plastic bags are often not biodegradable, leading to a buildup of waste in landfills. This waste can persist for hundreds of years, causing long-term environmental damage. Secondly, plastic bags can cause harm to wildlife. Animals may mistake plastic bags for food, leading to ingestion and subsequent health issues or even death. Additionally, plastic bags can entangle and trap animals, restricting their movement and causing injury or death.
The production of plastic bags also has environmental implications. The manufacturing process requires the use of fossil fuels, contributing to climate change and the depletion of non-renewable resources. Furthermore, the chemicals released during production can pollute the air and water, causing additional harm to ecosystems and human health.
Finally, plastic bags can contribute to soil and water pollution. When plastic bags break down into microplastics, these tiny particles can contaminate soil and water sources, affecting plant growth and the health of aquatic life.
For these reasons, it is essential to reduce the use of plastic bags and transition to more sustainable alternatives, such as bags made from organic natural textiles like cotton. By making environmentally conscious choices, we can protect both our clothing and the planet.
