Compostable & Biodegradable Clear Bags

Clear UK Compostable & Biodegradable NatureFlex Bags

Our UK compostable and biodegradable bags will decompose when bacteria or other living organisms act on them. Home compostable bags can be composted along with your garden waste, and sometimes food waste (depending on local kerbside collections) and will degrade quite quickly. Every year approximately 500 billion to 1 trillion plastic bags are used worldwide with a very small percentage being recycled, meaning a lot end up in landfill where they take many years to degrade.

NatureFlex Bags ™ Features            Natureflex

Made from 30 micron NatureFlex ™ which is a compostable film made from wood pulp sourced from managed locations. This film has excellent properties and is made from renewable, sustainable sources – an environmentally friendly choice. Due to the nature of this film, the film manufacturer recommends that the bags are used within 6 months and stored in suitable conditions. Recommended storage conditions are away from local heat sources, out of direct sunlight, and ideally between 17 and 23 degrees Celsius.

We also now stock clear, flat self seal bags in biodegradable & compostable Nativia®  film - ideal for Greeting Cards

Many of our customers have switched successfully from Polypropylene bags to compostable Natureflex ™ bags but we always recommend that you request a sample first to try with your product as Natureflex ™ does have a slightly different feel to Polypropylene.

If you still are unsure about how these bags are measured we recommend that you watch our video about "Choosing The Right Cellophane Bag for You, and Understanding the Measurements" - use the full screen option to see in the best quality.

Cellophane Bags Video Transcript

At Transpack we sell a large range of cellophane bags. Choosing the right bag for your needs may seem like a difficult task. Let me talk you through the differences between the gusseted bags, the display bags with the silver card base and the block bottom cellophane bags.


Each of these bags comes in a range of sizes and they are all manufactured using food safe film. Both the silver card bottom display bag and the block bottom base bag are designed with a flat base when opened out for easy filling. Like this. They are perfect for gifts, confectionery and food and look great tied up with a ribbon.


Gusseted cellophane bags are slightly different – they have a crimped base with special side gussets which provide a 3 dimensional bag, where the base flattens on filling. Like this. The bags are also measured slightly differently. The gusseted bags are measured like this. First of all the width (the closed width), the next measured is the open width with the gussets pushed out. Like this. The last measurement is the length, but it’s the length when the bag is sitting flat on the ground. So this length, as opposed to the whole length. The base measurement is the width of the base by the length of the base when its flat on the ground.


The other styles have no side gussets so are measured by the width, then by the full length and the base is again the width by this length.
