Frequently Asked Questions

How long does composting or biodegradation take?

The amount of time it takes for a product to biodegrade is determined by the composting environment. Industrial or commercial composting plants operate at higher temperatures, and materials must biodegrade within six months to meet certification requirements. Composting at home is more unpredictable, as it is affected by environmental elements like as temperature, humidity, and how often it is rotated. Materials can biodegrade in 12 months at a temperature of roughly 30°C to qualify for home compost certification. Check out our certificates page for additional details.

Is there a shelf life for compostable packaging?

Compostable materials, unlike most plastics, are intended to endure a long time. They won’t start decomposing on the shelf or in your warehouse on their own, but compostable polymers degrade with time, causing factors like sealing and lamination strength to diminish. We offer our compostable materials an 18-month shelf life in general before this happens. However, climatic variables like as heat and humidity have an impact on this; in hot and humid locations, the shelf life is lowered. To maintain a long shelf life, we recommend keeping all compostable items in dry, climate-controlled settings.

Are these materials certified compostable?

Green Bell Packaging’s biodegradable films and laminates, as well as any valves or zippers, are all certified compostable. Please see our Certifications page for further information.

Are there any microplastics left over after the compostable products decompose?

They don’t. Our materials are compostable, which means they’ve been subjected to extensive biodegradation testing to ensure that they breakdown fully into healthy organic matter.

Is there any plastic in compostable and bio-based recyclable products?

Our compostable products are produced from bioplastic, which is technically a form of plastic, and do not include plastic as most people know it. Green Bell Packaging offers a variety of bioplastics created with biodegradable Plantcell™ technology or recyclable Sugarflex™ films and laminates. For additional information, read our Science page, which delves further into these subjects.

Is it possible to recycle compostable items and materials?

Unfortunately, because compostable materials are supposed to be composted, they cannot be mechanically recycled. Commercial composting systems are currently not generally accessible on a kerbside basis, although this is fast changing, as is the pace of home composting.

What is the best way for me to compost Green Bell Packaging's products?

Composting is a critical component of a healthy circular economy. In our How to Compost blog post, we’ve covered all the fundamentals.

Are your mailers waterproof?

If you need a waterproof mailer, either our biodegradable or recyclable plastic mailers are the best option. Our paper mailers are water-resistant and can survive rain during transit, but they aren’t meant to be kept outside in the rain.

How durable are your mailers?

Our mailer bags are 100% waterproof and can bear a lot of weight. They’re also tear-resistant, and they’re made to evenly distribute weight throughout the bag. Order a sample pack and put it to the test.

What is the thickness of your mailers?

Our compostable and PCR recycled mailers come in 60µ or 2.36 mil thick. Our stock paper mailers are 180GSM. We’ve examined a lot of mailers and found these to be the best thicknesses for a great blend of affordability, durability, and long-term sustainability. You may determine the thickness of the material if you’re customising your packing.

Are the mailers transparent?

It’s entirely up to you! There are solid block colours as well as opaque (see-through) colours available. You can’t see the product being packaged within the standard envelopes that we offer online.

Are there any wholesale or large volume discounts available?

Yes, we provide volume discounts on stock orders of more than 2000 pieces. To talk with one of our Account Managers, please contact us.

How long does it take for online orders to be delivered?

 

Orders placed online are usually delivered within 24 hours. This can take anything from 1-3 days after despatch, depending on the delivery method (courier or bulk freight depending on the amount of your purchase).
