How do I purchase Econic® packaging?
You can purchase plain Econic packs and rewind film and also place orders for customised printing, sizes and features by contacting us here

Can I trial some Econic® bags before I commit to purchase them?
If you like the sound of Econic and want to check that it’s the right packaging for your business, you can order a fee sample pack here. If you have a packaging need that requires a customised pack or printing, you are welcome to request a low-cost trial to ensure the packaging is well-suited to your packaging requirements and processes. To ensure the manufacturing of Econic is as sustainable as possible, we evaluate each trial request to determine if the shipment location, proposed order quantities and what is going to be packed will make it viable. You can request a low-cost trial here 

What is the minimum order quantity for ready-made bags?
You can order as little as one pack of 100 bags if you are based in New Zealand, or a carton of 1000 bags if you are based anywhere else in the world. You can find out more information here.

Performance
(click + button to read answers)
Do Econic® packs provide the same barriers as my current bags?
All the testing we have done so far has shown that Econic provides the same barriers and functionality as standard petroleum-based packs. Our technical team can carry out in-house testing comparing your current packs with Econic to make sure your new Econic packs will deliver the same performance. You can contact our technical team here.

Do Econic® packs seal the same as standard bags?
Yes they do but at a lower temperature. Our technical team can advise you what pressure, temperature and dwell settings will give you the best results. You can find out more information about the sealing properties of Econic here  

Can we seal Econic® packaging on our existing equipment?
You should be able to seal Econic on your existing sealing equipment without any modification. It generally needs to be sealed at a slightly lower temperature than standard packaging. You can find out more information about the sealing properties of Econic here
Can Econic® be vacuum-sealed?
 Yes, Econic can be vacuum-sealed. The best vacuum-seals will be achieved by using a flat Econic bag with no gussets. If you would prefer to vacuum-seal a bag with gussets, we recommend that you carry out your own trials with our sample bags before committing to an order. You can order free samples here.
Can Econic® be used for frozen products?
Yes, Econic will withstand being frozen but it can be more brittle than traditional polyethylene plastic (PE). We recommend that you carry out your own trials with our sample bags before committing to an order. You can order free samples here.

Can we use Econic® for form, fill seal production lines?
Yes, Econic works well on both vertical and horizontal (flow wrap) form, fill seal production lines.

Can we run Econic® rewind film on our existing equipment?
Yes. Our technical team can advise you on the equipment settings that will give you the best results. You can contact our technical team here.  

I pack fresh roasted coffee. How do you stop the bags puffing up as the gas is released?
Degassing valves can be added to the Econic packs to allow gases to be released from the bags. We recommend that you let your coffee rest before packing if possible. Our technical team are happy to help you trial the packs through your supply chain and will advise you on the best way to pack to suit your roasting process. You can contact our technical team here  

Can we get a clear Econic® pack so consumers can view what's inside?
Our high clarity option, EconicClear,  is ideal for dry products such as pet biscuits and cereals. While still providing the same high oxygen barrier provided by standard Econic, the see-through compostable EconicClear film currently only provides a moderate moisture barrier, making it unsuitable at this stage for products requiring a high moisture barrier, like coffee and drinking chocolate. We are diligently working to expand our range of EconicClear films and welcome enquiries from companies wanting a high clarity option. Please contact us here

Is Econic® suitable for packing meat and wet products?
Because water is one of the catalysts for the composting process, and the material derived from corn starch used in most Econic films is particularly sensitive to moisture – Econic and EconicKraft films are not suitable for packing meat or wet products. However, EconicClear, which can be made without any corn-starch material, has been proven to be suitable for packing vacuum-sealed fresh chicken, provided it has a short shelf life of no more than 11-days. Because moisture levels, production processes and handling conditions can vary quite considerably, an EconicClear pack for any meat or non-dry product will need to be custom-designed and thoroughly tested to ensure it won’t start breaking down prematurely. You can contact our technical team for more information here.



Eco-Facts
(click + button to read answers)
What is Econic® packaging made from?
The majority of every Econic bag or wrapper is made from a combination of compostable films derived from sustainably-managed renewable resources. With the exception of the paper-outer on the EconicKraft bags, the films used to make Econic have been individually certified to the European and American compostability standards EN 13432 and ASTM6400.  Each completed Econic bag or wrapper also includes a percentage of compostable non-renewable components derived from petroleum, which can vary due to factors such as ink coverage, film thickness and customised performance adaptions. We are constantly working to increase the renewable content of Econic as suitable sustainable raw materials and resin formulas become
available. You can find out more here

 
Is the completed Econic packaging structure certified compostable?
With the exception of the paper-outer on the EconicKraft bags, the films used to make Econic have been individually certified to the European and American compostability standards EN 13432 and ASTM6400. We follow robust international testing regimes to ensure that all completed Econic variants meet recognised compostable packaging guidelines and tests carried out by our technical team have verified they break down in a typical composting environment. However, because we specialise in customising Econic, the completed packaging structure has not been officially certified. This allows us to tailor the material mix in each finished bag or film to suit the functionality and aesthetics required for specific products, brands, production lines and packing processes. Econic is also constantly evolving to include different design features, barrier properties and compostable raw material improvements as they become available. This can cause some structure variations even in our standard stock lines. So, in essence – while our technical team works hard to make sure the material mix used to make all our Econic bags and rewind falls within the accepted international composability guidelines – the constantly varying material mix makes certification impractical. The dynamic nature of Econic means that a compostable certification would only apply to the specific pack that was tested and even a slight customised adaption in any future packs could make that certification invalid. Convex believes that it is better not to certify the completed Econic film structure, rather than risk confusion about which products are certified and which ones are not. We instead provide our customers with detailed information about the make-up of their own specific packs.

Where can I compost my bags?
You can put your used Econic bags in your own home compost or worm farm, containing heat, water, oxygen, soil and micro-organisms. They can also be disposed of in a commercial composting facility if you have one in your area.

How long does it take for Econic® bags to break down in the compost?
Compost trials have shown that Econic bags can break down into small fragments in as little as 16 weeks. However, the rate of breakdown will vary depending on the compost environment, temperature and humidity. Therefore, it will likely take longer to break down if you live in a cold climate. You can find out more here.

What would happen if I bury my used Econic® bags in my garden? Will they break down?
Yes the bag will break down, but at a slower rate than it would in a compost environment containing heat, water, oxygen, soil and micro-organisms.

Is the bag 100% compostable?
No, but we are working on it.  The majority of every Econic bag or wrapper is made from a combination of compostable films derived from sustainably-managed renewable resources. With the exception of the paper-outer on the EconicKraft bags, the films used to make Econic have been individually certified to the European and American compostability standards EN 13432 and ASTM6400. We follow robust international testing regimes to ensure that all Econic variants meet recognised compostable packaging guidelines. Tests carried out by our technical team have verified that the completed Econic packaging structure and EconicKraft paper outer layer break down in a typical composting environment. The degassing valves we use for fresh roasted coffee are currently not compostable, but they can be easily peeled off the bags before composting.

Is Econic® packaging 100% renewable?
Unfortunately, no it is not. Each completed Econic bag or wrapper includes a percentage of compostable non-renewable components derived from petroleum, which can vary due to factors such as ink coverage, film thickness and customised performance adaptions. The estimated average percentage of renewable resources contained in Econic films is around 60%. Like you, we would ideally like this percentage to be higher but are limited at the moment by the availability of suitable sustainable raw materials that deliver the barrier and performance properties we need. We follow robust international testing regimes to ensure that all Econic variants meet recognised compostable packaging guidelines and tests carried out by our technical team have verified they break down in a typical composting environment. If you would like to know the percentage of renewable material contained in a specific type of Econic film, you can contact our technical team here.

Are the inks and adhesives safe for the environment?
Our suppliers have confirmed that the formulation of their inks and adhesives contain no heavy metals that would be harmful to worms, seedlings or the environment.

What about air miles?
We are definitely mindful of this. Our plan is to manufacture Econic in multiple locations worldwide as we open new markets to minimise the carbon emissions caused by long-haul transport, including air freight. We are in the very early stages of this, and will progress this area of our business as fast as we possibly can.

Do you have any other sustainable packaging options in addition to Econic®
Yes, we do. We are always working to develop new green packaging options and currently have a range of sustainable films available, offering a range of functions and features. You can view our full range of compostable packaging options here.
