With the continuous improvement of environmental awareness, biodegradable bags, as an environmentally friendly plastic bag, have attracted more and more attention. So, what is the production process of biodegradable bags? What is the current state of the market? This article will discuss these two aspects.
一. The production process of biodegradable bags
The production process of biodegradable bags mainly includes the selection of raw materials, production process, production equipment and so on.
1. Raw material selection
The raw materials of biodegradable bags are mainly biodegradable materials such as starch and polylactic acid. These materials have good biodegradability and can be quickly decomposed in the natural environment without causing pollution to the environment.
2. Production process
The production process of biodegradable bags mainly includes mixing, extrusion, stretching, cutting and other steps. Specifically, first mix raw materials such as starch and polylactic acid evenly, then extrude the mixture through an extruder, then stretch the formed film through a stretching machine, and finally cut the film into required shapes through a cutting machine. size.
3. Production equipment
The production equipment of biodegradable bags mainly includes extruders, stretching machines, cutting machines, etc. These devices have efficient and stable production capacity, which can meet the needs of mass production.
二. Market Status
As an environmentally friendly plastic bag, biodegradable bags have attracted more and more attention. At present, the market of biodegradable bags is mainly divided into two aspects: one is retail markets such as supermarkets and shopping malls; the other is service industries such as catering and express delivery.
In the retail market, biodegradable bags have gradually replaced traditional plastic bags and become the first choice for people when shopping. This is mainly due to the good biodegradability of the biodegradable bag, which can be quickly decomposed in the natural environment without causing pollution to the environment.
In the service industry, biodegradable bags have also been widely used. For example, in the catering industry, biodegradable bags can be used for boxed meals, takeaways, etc.; in the express delivery industry, biodegradable bags can be used for packaging express delivery, items, etc. These applications can not only reduce the use of plastic bags, but also reduce the risk of environmental pollution.
In short, the production process and market status of biodegradable bags have shown its environmental protection advantages and broad prospects. With the continuous improvement of environmental awareness, it is believed that biodegradable bags will be more widely used and promoted.
