Disposable bags are used daily, but traditional ones take hundreds of years to fully decompose—far too slow, placing an excessive burden on the land. Consequently, governments have mandated that modern disposable bags must be environmentally friendly and rapidly degradable. But how quickly should a biodegradable disposable bag decompose to qualify as "rapid degradation"? And does fast degradation affect its shelf life?

Shelf Life of Biodegradable Disposable Bags

Many assume disposable bags have a long shelf life, like other products that last 1-2 years. In reality, biodegradable disposable bags only have a shelf life of six months. Why is that? Their material composition inherently limits their storage period to half a year.

Beyond six months, the starch-based raw materials in the bags will deteriorate, compromising their performance. Simply put, the bag's functionality changes after six months. Traditional disposable bags could last two years because they were made of polystyrene.

While polystyrene enables long-term storage, its decomposition rate is extremely slow—taking hundreds of years to fully break down. This pace hinders sustainable development, so polystyrene disposable bags are being replaced and phased out in favor of more eco-friendly plant starch alternatives.

Degradation Time of Biodegradable Disposable Bags

Though biodegradable disposable bags are known for fast decomposition, many people are unaware of the specific timeframe that defines "rapid degradation." Currently available biodegradable disposable bags require only a few months to fully decompose—matching the brevity of their shelf life.

In summary, despite having a shelf life of just a few months, biodegradable disposable bags decompose within the same timeframe. This balance of shelf life and degradation speed meets both practical usage needs and environmental decomposition requirements, eliminating the need for centuries-long waiting periods for full degradation and contributing significantly to environmental protection.
