At a time when the concept of environmental protection is becoming more and more popular, the packaging field is also constantly exploring more sustainable solutions, and biodegradable packaging bags and recyclable packaging bags are important results. However, there are significant differences between them.

First of all, from the perspective of material composition, degradable packaging bags are mainly composed of PBAT+PLA, cellulose film, paper, etc. These materials can be broken down by microorganisms under certain conditions and eventually converted into environmentally friendly substances. Recyclable bags, on the other hand, are usually made of a single material, PE, which is relatively single.

Secondly, there are also significant differences in the terms of process auxiliary materials. Degradable packaging bags use water-based ink when printing, and water-based glue is used in the composite process. Water-based inks and water-based glues have the advantages of low volatility and low toxicity, and have less impact on the environment and human health. In contrast, the printing ink of recyclable packaging bags is oil-based, and the composite glue is also oil-based. Oil-based inks and oil-based glues may release volatile organic compounds during production and use, causing certain pollution to the environment.

The advantage of biodegradable bags is that they can gradually decompose in the natural environment, reducing the environmental stress caused by long-term existence. However, it should be noted that the degradation process usually requires specific conditions, such as a certain temperature, humidity and microbial environment. Recyclable packaging bags reduce the consumption of raw materials through recycling, but the recycling process may require higher costs and complex technical means to ensure the quality and performance of the materials.

To sum up, biodegradable packaging bags and recyclable packaging bags have their own characteristics and advantages. In practical application, the appropriate bag type should be selected according to the specific product needs, use scenarios and environmental protection goals to achieve the best effect of effective use of resources and environmental protection.

Biodegradable packaging bags represent the efforts of the packaging industry to move towards sustainable development and contribute to building a green and low-carbon future
