FAQ
What is woven polypropylene?+
Woven polypropylene is a strong, durable plastic material known for its resistance to abrasion and chemicals. It's commonly used in applications requiring robustness like garden bags because it can handle heavy loads and isn’t easily torn.
Are these bags suitable for composting?+
While the bags themselves won’t compost, they are excellent for collecting grass cuttings, leaves, and other biodegradable materials destined for your compost heap. Ensure you line the bag with compostable sacks to fully embrace a sustainable approach.
How many times can I reuse these bags?+
With proper care, these 120 Litre bags can be reused multiple times – typically up to 3-4 times for average garden waste. Avoid overloading them and ensure the handles are inspected regularly for wear and tear.
Do these bags have a strong odour barrier?+
The woven polypropylene construction provides a degree of odour containment, but it's not entirely airtight. To minimise smells, avoid layering multiple bags or leaving waste in the bag for extended periods.
What size are the handles?+
The reinforced handles are approximately 60cm long and designed to provide a secure grip when carrying full bags. They’re wide enough to comfortably fit two hands.
Are these bags suitable for heavy, wet waste?+
While durable, prolonged exposure to very wet or saturated waste can weaken the polypropylene over time. Avoid leaving excessively wet materials in the bag for extended periods – consider using a liner.
Can I use these bags with a wheelie bin?+
Yes, these 120 Litre bags are perfectly suitable for use with wheeled bins. Ensure you don’t exceed the recommended weight limit of your bin to avoid damage or safety concerns.
What is the thickness of the polypropylene material?+
The woven polypropylene has a density of approximately 0.9 - 1.0 g/cm³, offering substantial strength and resistance to tearing, much thicker than thinner plastic bags.
Are these bags suitable for collecting wood chip mulch?+
These bags are generally suitable for collecting woodchip mulch but avoid using them repeatedly with high volumes of wood chips as this can degrade the polypropylene over time. Consider a dedicated wood waste bag instead.
How do I clean these bags after use?+
Clean the bags with mild soap and water. Avoid using harsh chemicals or abrasive cleaners that could damage the material. Ensure they are thoroughly dried before storing to prevent mildew growth.
