Functionality


Econic® has been specifically designed to lock in the freshness and taste of coffee and dry products. It works well for flow wrap applications and provides the same functionality as traditional fossil fuel-based packs, with the added advantage of being compostable. The film and finished pack shape can be customised to suit the functionality, processing and barrier requirements of most dry food items and can include features such as four side seals, compostable zip closures, tear notches, angle seals, hang sells and degassing valves for fresh roasted coffee.


Superior Taste & Shelf-Life

The superior shelf-life provided by Econic® was confirmed in 2013 during a 16-week shelf life trial led by a certified Q Coffee grader with the US Coffee Quality Institute. The trial validated the functionality of the degassing valves and demonstrated that Econic® with these valves performs the same as the standard petroleum-based coffee packs sold into the supermarket trade. You can download the taste report here

The trials were carried out in a lab environment using an internationally recognised scoring format to compare the impact of the various Econic® packaging options and traditional paper packs on the flavour, after taste acidity, sweetness and body of fresh ground light roasted and dark roasted coffee over time.

  • At three months all the Econic® coffees were still consumable, whereas the coffee packed in the unsealed and unvented paper pack deteriorated very quickly – with an optimum shelf prediction of just 10 days.
  • At the four-month mark, the Econic® packs with the valves held the most flavour and body across both blends and delivered a cup quality equal to a traditional plastic laminate pack.

Food Safety

Convex is highly committed to ensuring Econic® packaging meets all applicable food contact safety requirements:

  • Each of the cellulose and cornstarch components has food contact status approval from the US FDA; and
  • We manufacture the Econic® bags in a factory that has a HACCP approved food safety programme

Sealing

Econic® provides equivalent sealing properties to standard petroleum-based films and should seal on your existing sealing equipment without any modification. Econic® generally needs to be sealed at a slightly lower temperature than standard packaging. Our technical team is available to advise you on the sealing temperature and equipment settings that will give you the best results.

Coffee Degassing

Econic® packaging is being successfully used by numerous roasters for fresh ground coffee and whole beans. Venting valves can be added to the packs to allow gases to be released from the packs. 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.

High Clarity Econic®

A high clarity Econic®Clear film is available to help boost the branding and shelf appeal of dry goods, such as pet biscuits and cereals, by allowing consumers to view the packaged product. Econic®Clear provides the same high oxygen barrier as standard Econic® and a lower, more moderate, moisture barrier. It is not suitable at this stage for products requiring a high moisture barrier, like coffee and drinking chocolate. Contact Us to find out more.

Hear what our customers have to say!

“The barrier the packaging film offers is a high priority for Loving Earth because we don’t rely on anything unnatural – like preservatives, flavours or emulsifiers – to keep our products fresh. We only use really simple organic premium ingredients. At the end of the day if you are going to use a compostable film you need to make sure it will keep the product fresh, and we are confident Econic® will do that. The top layer of the Econic® film also provides a great printing surface.”
