Calcium carbonate (CaCO3) is a widely occurring natural mineral, mainly composed of calcium, carbon, and oxygen. People often use it to make plastic bags and other plastic products. Why add calcium carbonate? Because it has five advantages.
Firstly, it can reduce the thickness of plastic bags. Many people know that environmentally friendly plastic bags are thinner than traditional bags. This thin design can save raw materials and reduce plastic pollution. So, how to make plastic bags thinner? The answer is to add calcium carbonate. Due to the high hardness of calcium carbonate, adding an appropriate amount of calcium carbonate to the plastic matrix can significantly change the physical properties of the plastic, improve its strength and hardness, and make plastic bags thinner and lighter without losing strength and stability.
Secondly, it can reduce costs. Calcium carbonate has a low price and can replace some plastic raw materials, thereby reducing production costs. At the same time, adding calcium carbonate can also improve the appearance, and enhance glossiness, aesthetics, durability, and portable storage.
Thirdly, it can improve production efficiency. Manufacturers hope to produce plastic bags as soon as possible, and improving production efficiency has become a natural demand. Adding an appropriate amount of calcium carbonate will make the raw materials smoother and easier to process, thereby improving production efficiency and shortening production cycles.
Fourthly, it can increase the stability of plastic bags. With the increasing emphasis on environmental protection in metaphysics and environmental protection, the stability and safety of plastic bags are also receiving increasing attention. Adding an appropriate amount of calcium carbonate to the plastic matrix not only reduces the degree of warping of the plastic bag but also improves its nondeformability. Correspondingly, plastic bags are more stable during use and can better meet the needs of users.
Fifth, it can reduce environmental pollution. The last and most crucial point. During the processing process, setting calcium carbonate fillers can not only reduce the density of plastic bags, make the bag flexible and thin, and make users feel better, but also reduce the generation of pollutants. In addition, calcium carbonate is an environmentally friendly material that does not release toxic substances and does not cause any pollution to the environment.
With the rapid development of the economy, people have found that the white pollution caused by traditional plastic bags is becoming increasingly serious, and people's environmental awareness is also increasing. Although traditional plastic bags bring us a lot of convenience, they are recommended to use less or even not as they can pollute the environment. Of course, you can also use biodegradable plastic bags. Let's follow the editor to learn about the comparison between biodegradable plastic bags and traditional plastic bags, Where is the victory?
Biodegradable plastic bags are a type of environmentally friendly plastic bag, which have advantages over traditional plastic bags in terms of performance, practicality, degradability, and safety. The performance of degradable plastic bags in specific fields can surpass traditional plastic bags. Compared with similar traditional plastics, the application performance and hygiene of degradable plastic bags are similar. In addition, after using degradable plastic bags, they can quickly complete degradation in the natural environment and reduce the impact on the environment. In terms of safety, the degradation process and residual substances of biodegradable plastic bags are harmless to the environment and will not affect the survival of us and other organisms.
Although traditional plastic bags bring convenience to our lives, they also cause environmental pollution. Some non-environmentally friendly bags cannot be used to hold food, which can pose a threat to human health. In addition, plastic itself can release harmful gases and pollute the environment. Due to long-term accumulation in sealed bags, the concentration increases with increasing sealing time, resulting in varying degrees of contamination of the food in the bags, which has a particularly prominent impact on children's health and development. In addition, polyvinyl chloride plastic products cannot be used to store alcoholic or oily foods, otherwise, the lead in the bag will dissolve into the food; At the same time, this non-environmentally friendly bag cannot hold food at a temperature above 45°C.
There are two main types of environmental pollution caused by non-environmentally friendly plastic bags, namely visual pollution and potential hazards. Visual pollution mainly damages the landscape and is more prominent among white pollution. The potential harm is the long-term environmental problems caused by the difficulty in the degradation of waste plastic products after they enter the natural environment. We all know that plastic structures are stable and not easily damaged, which means that if waste plastic waste is not recycled, it will become a permanent pollutant in the environment and continue to accumulate.
Non-environmentally friendly plastic bags not only affect the development of industrial and agricultural production but also affect the sustainable use of land due to improper handling. So I hope everyone can use environmentally friendly plastic bags - degradable plastic bags - in the future to protect our homes!
