What is 100% compostable packaging bags?
100% compostable packaging bags are a special type of packaging material that is made of fully degradable bio-based materials and can be decomposed into water, carbon dioxide and organic matter under industrial composting conditions. The original intention of the design of this type of packaging bag is to reduce the pollution of traditional plastic packaging to the environment, especially to reduce “white pollution”. Compared with traditional non-degradable plastic packaging bags, 100% compostable packaging bags can be decomposed in a composting environment by the action of microorganisms at the end of their life cycle without leaving harmful residues or microplastics. This means that they can return to nature without polluting soil and water sources, helping to reduce the burden on landfills and greenhouse gas emissions.
The production materials of 100% compostable packaging bags are usually derived from renewable resources, such as corn starch, potato starch, cellulose, etc., which can have the required packaging properties, such as strength, sealing, etc., after specific processing and formulation, while maintaining their biodegradability. The use of 100% compostable packaging bags requires corresponding composting facilities to realize their environmental value. In a home or industrial composting environment, these bags can be completely decomposed in a few weeks to months under certain temperature, humidity and microbial action. Therefore, while promoting this type of bag, it is also necessary to improve public awareness of composting and the construction of composting facilities.
What are the benefits?
The use of 100% compostable bags provides an environmentally friendly solution. They can be completely decomposed in industrial composting facilities and converted into organic matter that is beneficial to the soil, thereby reducing the generation of plastic waste and long-term pollution to the environment. This type of bag not only helps to reduce greenhouse gas emissions and promote resource recycling, but also improves soil quality and reduces the demand for chemical fertilizers. In addition, companies can use this type of bag to enhance their brand image and demonstrate their commitment to sustainable development, while meeting the growing requirements of environmental regulations and consumers’ preference for environmentally friendly products. By promoting the use of such products, it can also promote scientific and technological innovation and development in related fields, and provide new ideas and methods for solving the problem of plastic pollution.
Types of 100% compostable bags
100% compostable bags are eco-friendly bags made of bio-based materials. They are designed to be fully biodegradable under composting conditions at the end of their service life and converted into environmentally friendly substances such as carbon dioxide and water. There are various types of such bags, including but not limited to the following:
PLA bags
These bags are made of polylactic acid (PLA). They are not only 100% compostable, but can also be decomposed into substances that are harmless to soil and water.
Paper bags
These bags are designed to be decomposed by microorganisms under composting conditions after completing their packaging tasks, and converted into water, carbon dioxide and organic fertilizer, thereby reducing the impact on the environment. The production process of paper compostable bags may adopt biodegradable coating technology or use biodegradable adhesives to ensure that the final product can achieve environmental goals while meeting the necessary physical properties. However, it is worth noting that not all paper bags have compostable properties. Some paper bags may be difficult to biodegrade due to being coated with plastic or other chemicals. Therefore, when choosing paper compostable packaging bags, it is key to understand their specific material composition and whether they have relevant environmental certifications.
These different types of 100% compostable packaging bags provide the market with a wide range of options to meet the needs of different application scenarios and help promote the shift to more sustainable and environmentally friendly packaging solutions.
Functional and protective packaging
Compostable packaging bags are an innovative environmentally friendly packaging solution that replaces traditional petroleum-based plastics by using bio-based materials such as corn starch, sugar cane or potato starch. These naturally sourced materials give the packaging bags the ability to biodegrade, and under proper composting conditions, they can be converted into water, carbon dioxide and organic fertilizer, thereby reducing the risk of long-term environmental pollution.
These packaging bags not only have good physical properties such as elasticity, waterproofness and tensile strength, ensuring the practicality and protection of the packaging, but they are also internationally certified to confirm their biodegradability and safety, suitable for contact with food. In addition, the customized service of compostable packaging bags allows them to be designed and printed according to specific needs, increasing the flexibility of use.
With the increasing awareness of environmental protection and the pursuit of a sustainable lifestyle, compostable packaging bags are becoming more and more popular in the market and among consumers. Not only do they reduce carbon footprints, they also drive the shift toward greener, more environmentally friendly packaging solutions by reducing reliance on fossil fuels. The environmentally friendly nature and functionality of compostable packaging bags make them a powerful alternative to traditional plastic packaging, providing a viable path to protecting our planet’s environment.
