FAQ
What is the polyethylene film thickness of these bags?+
The bags are constructed from a 40 mil (millimetre) thick polyethylene film, providing excellent durability and resistance to tearing. This thickness ensures they can handle heavy loads of garden waste without compromising their integrity.
Are these bags suitable for composting?+
While the bags themselves aren't compostable, they are designed to hold compostable materials securely, allowing you to efficiently collect your green waste for composting elsewhere. Ensure any tape used is also compostable.
How many times can I reuse a 300 Litre bag?+
With careful handling and proper closure using compostable tape, these bags can typically be reused several times – potentially up to 10-15 times depending on the volume and type of waste being collected.
What size are the handles on the bags?+
The handles are approximately 60cm long and are reinforced for added strength, allowing you to comfortably carry a full bag without strain. They're designed to handle the weight of up to 300 litres of waste.
Do these bags have any special features for easy emptying?+
The bags feature a rounded base design which helps prevent them from snagging on edges or sticking to other items during transport, making emptying easier. The reinforced handles also assist with this process.
What type of tape should I use to close the bags?+
We recommend using compostable tape specifically designed for securing garden waste bags. This ensures that your tape is biodegradable and won't contaminate your composting efforts.
Are these bags suitable for collecting wet or damp waste?+
Yes, these bags are designed to handle both dry and slightly damp garden waste. However, excessive moisture can weaken the film over time, so avoid storing very wet materials in the bag for extended periods.
What is the recommended storage method for these bags?+
Store the bags in a cool, dry place away from direct sunlight to prevent degradation of the polyethylene film. Avoid stacking them too high as this could put excessive pressure on the handles and seams.
Can I use these bags with a wheelie bin?+
While you can use these bags alongside a wheelie bin for collection, we advise against filling the bag completely full to allow space for compaction and prevent overflowing. Ensure they are securely closed.
What is the warranty on these 300 Litre bags?+
These garden waste bags come with standard Amazon UK returns terms. If you're not satisfied, you can return them within 30 days of receipt for a refund or replacement (subject to conditions).
