What is composting, and what are the benefits of composting?

Composting is a natural breakdown of material into rich soil. Composting organic waste (yard trimmings, food waste, etc.) helps divert organic waste from landfills. When added back to land projects, compost promotes healthy plant growth, improves soil moisture retention, amends sandy/clay soils, and improves crop nutrient content.

Why composting logo is mandatory?

The composting logo is designed to address the confusion that has existed between truly compostable materials and oxo-degradable plastics by building credibility and recognition for products that meet the ASTM D6400 /En13432/AS 4736 Standards among consumers, composters, regulators, and others. It is designed to be easily recognizable and able to be placed on the actual product and packaging and sales literature. 

Bubble Mailers

How long will it take for the product to compost?

Supr Pack bubble mailer is a 100% biodegradable and compostable product. The time for the mailers to fully compost depends on the environment. Commercial or industrial compost facilities that run on the certified protocol has higher temperature for composting. Hence the Supr Pack bubble mailers biodegrade within six months.

Since home composts are dependent on external factors like humidity, temperature, and how often the mailers are turned, the time for the bubble mailers to biodegrade can be within 12 months at 30 degrees Celsius.

What is the shelf-life of bubble mailer?

Our compostable bubble mailers are designed to have a better shelf-life than most plastic bags. They can last up to 12 months when they are kept in a cool, dry environment, away from direct sunlight or heat. If the bubble mailers are kept in a climate-controlled environment, we can assure you the product won’t start composting on the shelf immediately. However, since they are biodegradable products, the polymers can weaken, and the lamination strength can deteriorate.

After composting does the bubble mailers leave any micro-plastics behind?

We at Supr Packs develop and manufacture the bubble mailers and ensure they pass through biodegradable testing. In addition, we ensure that they are made of fully biodegradable products, so no micro-plastics are left behind after biodegrading.
