Products & materials

Products and materials in sustainable packaging focus on using eco-friendly, renewable, and recyclable resources. This includes biodegradable plastics, recycled paper, and materials derived from plants or other renewable sources. The goal is to reduce environmental impact by minimizing waste, conserving natural resources, and ensuring the packaging can be effectively recycled or composted at the end of its life cycle. Sustainable materials are designed to maintain functionality and durability while promoting a circular economy.

This is almost imperceptible to the naked eye and does not effect packaging or print quality. Speak to one of our packaging experts about getting your hands on samples of our recycled products!

Can my compostable packaging be recycled?

Compostable materials are designed to be composted. Unfortunately, that means that they generally cannot be recycled and shouldn't go into a recycling stream. Although commercial composting systems are not widely available presently they are growing rapidly, so too is the rate of home composting. For further reading please visit our Resource Hub.

How long does it take to compost?

Composting timeframe depends on the exact conditions of the compost. Industrial or commercial composts run at higher temperatures and generally operate on a time frame of 2-3 months. Home composts are more variable and dependent on things like climate and how well they are managed. Home compost certification assumes the compost environment operates ~30°C and in order to achieve certification products must fully biodegrade within 12 months.

Does compostable packaging have a shelf-life?

Unlike plastics, compostable materials are designed to have a shelf-life. They won't start spontaneously composting on the shelf or in your warehouse but over time things like sealing and lamination strength will start to deteriorate. In general, we recommend our compostable materials be used within 12-18 months depending on the product being filled as well as storage conditions. However this is influenced by atmospheric conditions like heat and humidity so in particularly hot and humid climates this is reduced. We recommend storing all compostable materials in dry climate controlled conditions as best practice to ensure best shelf-life of the packaging itself.
