With the promulgation of national plastic ban regulations, degradable plastic bags are gradually replacing disposable ordinary plastic bags and becoming the mainstream now. Compared with cheap paper takeaway tableware, many merchants will choose to buy biodegradable plastic bags for use. Compared with plastic bags, although they are more prone to damage, they are also more environmentally friendly and convenient. Compared with plastic bags that are difficult to degrade How long does it take for degradable plastic bags to degrade?

1. The way of degradation

There are many ways that degradable plastic bags can be degraded. The more common way is to bury them in the soil for degradation. Because the soil contains microorganisms and other factors, it can help plastic bags to degrade better, so the general natural degradation days are only 180 days or so. Of course, this time is only relative to fully biodegradable plastic bags.

Another way of degradation is to throw it into the sea for water degradation. Of course, this method is not very commonly used. Even if it enters the sea, most of it is discarded artificially. It is more effective to degrade in the soil. As long as the degradable plastic bags are fully biological, it only takes 1-2 months to degrade when thrown into the sea.

2. Composition of biodegradable plastic bags

Of course, the composition of degradable plastic bags is also an important factor affecting the degradation time of degradable plastic bags. Now there are many brands of degradable plastic bags on the market, and the prices of different brands are also different. When choosing, merchants will also have different choices. From an environmental point of view, fully biodegradable plastic bags are more environmentally friendly, but the price is bound to be more expensive.

Fully biodegradable plastic bags are divided into two types, bio-based biodegradable plastic bags and petrochemical-based biodegradable plastic bags. The latter are more widely used in people's lives and are easier to degrade. But no matter what type of degradable plastic bags, it is necessary to create a moderately degradable environment when degrading, so that the degradation time can be shortened.
