The Truth About Vacuum Bags


Plastic vacuum and compression bags have become quite popular over the last few years to save space in your wardrobe and linen cupboard.

Sure, they protect your items from dust and dirt, but have you ever stopped to think about the potential risks and damage these types of "space-saving vacuum-sealed bags" can cause to your stored items? Or the environmental impact these types of plastics and materials have on the world around us?

If you are storing your items for more than six months in these types of bags - or low-and-behold you've forgotten about them altogether and left them in hot and humid conditions over the years - are you aware of the real effects these plastic vacuum bags have on your winter woollies, seasonal items, blankets, throws and the like?

Sure they save space; but at what cost to you, your belongings, and the environment?

We explore the natural and safe alternatives to vacuum-sealed plastic bags and why 100% Cotton Storage Bags are your simple storage solution when it comes to protecting your favourite and seasonal items and promoting their longevity. 


Vacuum bag


Storing your seasonal items in a plastic vacuum or compression bag can have a detrimental effect, particularly when stored long term. 

Sure they're great space savers; however, most of these bags are manufactured from polyethylene and polyamide plastics (more on this below) and provide no real or prolonged benefit when it comes to storing and preserving your items.

My own experience with these storage bags has caused considerable damage to my clothing; particularly to my more delicate and seasonal items such as my wool jumpers, beautiful cashmere tops, heirlooms, blankets and other pieces.  

What I didn't realise at the time when I was looking for a storage solution, was that these vacuum clothes bags were essentially 'sucking the life out' and 'flattening' my belongings to save space! What? Yes, but true. 

I didn't think at the time "this can't be good," until I discovered, it wasn't!

Here's why.



Plastic doesn't breathe. With vacuum bags and plastic in general, fresh air cannot circulate in and around your wardrobe or your belongings. Fabrics need to breathe - just like us. By compressing the air out of your clothes, you are not rejuvenating the fabrics. Instead, you are suffocating the fabrics and damaging the material fibres, creating unnecessary creases and making your garments' and linens lose their shape. 

Fresh air through open doorsIt is imperative to allow your store items to breathe, to allow fresh air to circulate in and around your wardrobe, cupboards and storage space. This 'breathing space' helps prolong their longevity and nourishes the fabric fibres so you can enjoy wearing and using your items from year-to-year and beyond. More on this below. 

Plastic melts. Have you noticed that when you store these plastic vacuum bags on top of each other, you sometimes have to peel them apart as the lack of air and warm storage conditions have caused them to stick together, over time? It does happen. Then you're faced with replacing them, and this can be costly. But the most significant cost is replacing your cherished garments, linens, and seasonal items, particularly if they're heirlooms and sentimental pieces.


Smelly odour from plastic vacuum bagsPlastic odour absorption. Long term storage in any plastic will eventually absorb that irksome plastic odour, particularly when storing your belongings in closed spaces such as cupboards, attics, garages, and areas that lack air ventilation.

Discolouration and fading. Long term storage in vacuum bags can cause discolouration and fading due to unfavourable storage conditions. The longer you leave your belongings in these types of bags, the more susceptible they are to discolouration and fading. Coupling that with humid conditions and you have a recipe for disaster.   


Colour transfer can occur. Colour transfer occurs when fabrics are stored together and on top of each other, causing unwanted damage. It can be challenging to remove these sometimes permanent stains, particularly if you've stored natural fabrics and materials in these compression bags long term - six to twelve months or longer - causing the fabric dyes to transfer. 









Garbage rubbish pileThe truth is, it can take up to 450 years for plastic to degrade or completely decompose. Some plastic bottles can take up to 1000 years to biodegrade, and other plastic bottles made with Polyethylene Terephthalate (PET or PETE) will NEVER biodegrade.

Polyethylene is one of the most widely produced plastics. Tens of millions of tonnes are produced each year gloabally. It is used in plastic bottles and containers for packaging foods, beverages, personal care products, and many other consumer products are made from polyethylene - including vacuum bags!

Polyamide plastic or ‘nylons' is a plastic material often used to print 3D objects and items such as eyeglass frames, fishing lines, textiles and carpets. It is also used in vacuum storage bags.

These facts will surely make you think twice about purchasing that 'plastic' bottle or cheap vacuum storage bags when there are other natural and environmentally-friendly, safe alternatives to storing your manchester and out-of-season items. 


100% COTTON STORAGE BAGS | A natural alternative

Cotton is one of the most biodegradable fabrics available.

Cotton can take as little as one week to biodegrade, but it usually takes about 5 - 6 months making it the natural, go-to fabric that Kazzi Kovers loves!
