New trend-biodegradable corn starch bags

Biodegradable corn starch bags are made of cornflour/cassava as raw materials. They are green and biodegradable naturally with
a relatively short shelf life. You can customize the biodegradable carrier bags for packaging. Besides, many brands need eco-friendly packaging solutions. Then, they need to make compostable ziplock bags or self-adhesive bags for food, vegetable, garbage, etc. So, it becomes a new hot trend in the plastic packaging field.

We supply biodegradable corn starch bags at various bags at customers’ requests. Such as degradable composite bags, vest bags, flat pockets, express bags, etc. Most of them in daily life are vest bags (that is, the kind used in supermarkets). And people use it for shopping or clothing/garment packaging.

Why are biodegradable bags greener than traditional PE plastic bags?

Compared with traditional plastic packaging bags (PE), the chemical properties of cornstarch, cassava, etc. are not stable and are easily degraded in the natural environment.

Except for the difference in chemical properties, biodegradable bags feel more delicate. And they are skin-friendly than traditional plastic bags.

The birth of biodegradable bags relieved the pressure on the environment caused by daily chemicals. So, it is an excellent choice for both human health and natural health.

Corn starch

Corn starch is a colorless and transparent liquid lactic acid first extracted from corn through modern biotech. And the main raw materials are corn, corn cob, and corn stalk. Besides, we can use corn starch as the raw material for degradable plastic bags. Then, it is the most ideal raw material to replace PO to make vest bags.

What is the difference between corn starch bag and regular PO bag?

Corn starch is generally milky white, very cloudy, and thick. It feels hemp-like and has a paper-like texture. Also, it is much thicker and heavier than ordinary plastic bags.

Compared with ordinary PO vest bags, the degradation time of corn starch bags is short. So, a corn starch bag will only take 60 to 180 days. But, it takes about 200 years for an ordinary PO plastic bag to be completely degraded. This is why the country promotes bio-degradable bags.

Types of eco-friendly plastic bags

What is eco-friendly plastic bags? Eco-friendly plastic bags do not refer to a certain kind of plastic bag. It is a general term for all plastic bags with natural protection properties.

There are two main types of eco-friendly plastic bags commonly used in daily life. One is a degradable plastic bag. And the other is a fully degradable plastic bag.

Degradable plastic bag

The degradable plastic bag is made of degradable materials (like starch) and ordinary plastic materials (such as PE). And its material degrades rapidly after the plastic bag is discarded. Yet, ordinary plastics do not degrade. That is to say, this green plastic bag will be broken down into pieces if we discarded it. Then, the pieces are hard-to-degrade ordinary plastic materials that reduce the pressure on the nature.

Fully degradable plastic bag

Fully degradable plastic bags are not strictly plastic bags anymore. It’s just the same length as a plastic bag. So people still call them plastic bags. Because of the cost, only some high-end stores or large supermarket chains will use it in daily life. Of course, they will degrade quickly after being thrown away.

The essence of biodegradable corn starch bags

What is the principle of biodegradable corn starch bags cycle?

  1. Using cornflour/cassava as a raw material;
  2. Fully biodegradable resin;
  3. Biodegradable Products;
  4. Garbage can turn into organic fertilizer;
  5. Organic fertilizers can be used for crop growth;

Why promote biodegradable corn starch bags?

At present, the most serious natural problem we are facing is white pollution. And white pollution is due to the excessive use of non-degradable plastics and random disposal. And the non-degradable garbage is mainly non-degradable plastic garbage bags. Thus, the promotion of bio-degradable bags can reduce the use of non-degradable plastic products. Then it can achieve the purpose of reducing white pollution.

How to promote biodegradable corn starch bags ?

First, everyone should join the ranks of natural protection. In daily life, use degradable bags and reduce the use of non-degradable plastic bags. Brands can also use biodegradable corn starch bags to promote the development of national natural protection.
