Coffee Knock Tube Liner

Compost-A-Pak® is proudly an Australian family owned business, established in 2007. Our manufacturing processes are driven by our passion for sustainability.

All Compost-A-Pak® products are made from a natural starch-based polymer derived from corn. We choose corn, as it is an annually renewable crop, unlike trees, which can take years to grow. The actual crops are sourced from international GMO-free regions with high levels of rain, to minimise irrigation, and the corn selected is third grade corn. This is basically spoilt corn, a waste product traditionally left by farmers to rot, that is not suitable for human or animal consumption.

Using purpose built biodegradable resin extruders, a resin is extracted from the combination of corn starch, biodegradable ingredients and some propriety elements and from this blown film bags are formed in a range of designs and sizes. We are extremely proud that through re-engineering this purpose-built equipment, our liners are made with significantly less electricity consumption, compared to manufacturing on conventional extrusion equipment. The products are also printed in soy-based inks, with environmental messages and information promoting their difference as a sustainable alternative to plastics. They have a recommended shelf life of twelve months.

Most importantly Compost-A-Pak® Coffee Knock Tube Liners are Certified compostable to the stricter Australian standards, for both home composting (AS5810) and commercial composting (AS4736), as well as the relevant European, American and Japanese standards for commercial composting.

In the same way as vegetable scraps, the products in their entirety will break down into humus, water and carbon dioxide in a commercial composting facility in a matter of weeks. These certifications ensure you can be confident there will be no harmful residue as the liners break down. In fact, the bags are also safe for use in organic farms, food contact, animal feed and can also be also used in worm farms.
