Although traditional plastic mailing bags are widely used, the pollution problem they cause to the environment is becoming increasingly serious. In order to solve this problem, Biodegradable Mailer Bags came into being and became the representative of green and environmentally friendly packaging. They can not only meet daily logistics needs, but also quickly degrade after use, reducing the burden on the environment. Biodegradable mailer bags are usually made of the following raw materials.
1. Plant-based materials:
Many biodegradable mailers use plant-based materials as raw materials. These materials come from renewable plant resources, usually starch or cellulose. These materials can decompose in the natural environment and reduce the long-term impact of plastic on the environment. For example, corn starch is a common plant-based material that can be processed into compostable mailing bags. This material is not only biodegradable, but also does not release harmful substances, which meets the requirements of ecological and environmental protection.
In addition, compostable bubble mailers also often use plant-based materials. With the design of bubble film, they can protect the items while ensuring that the degradation process meets environmental protection standards. Eco friendly poly mailers made of plant-based materials can be decomposed by soil microorganisms after use, turning into water, carbon dioxide and organic matter, forming an environmentally friendly cycle.
2. Polylactic acid (PLA) material:
Polylactic acid (PLA) is a biodegradable plastic fermented from plants such as corn or sugarcane, which is widely used in the biodegradable packaging industry. PLA not only has good transparency, strength and flexibility, but also can be biodegraded under suitable conditions. As a common biodegradable mailers material, PLA material can be completely decomposed in the soil without affecting the performance of the mailing bag.
Polylactic acid has high environmental value, low carbon emissions in its production process, and its degradation process does not leave harmful substances, so it is used in many eco-friendly mailing bags. Whether it is a single PLA film bag or a composite material combining PLA and plant fibers, PLA plays an important role in modern packaging solutions.
3. Recycled paper and paper composite materials:
In addition to plant-based plastics and PLA materials, some compostable mailing bags also use recycled paper and paper composite materials as substrates. These materials not only meet the requirements of biodegradability, but also have good recyclability. The use of recycled paper reduces dependence on wood and promotes the recycling of resources. Paper composite materials combine the biodegradability of paper with the durability of other materials, such as the use of special coatings or toughening agents to make the bags more durable.
These paper eco friendly poly mailers can effectively resist water and moisture during transportation, and can be composted after use and enter the natural cycle. Paper biodegradable mailer bags strike a good balance between environmental protection and functionality, especially for those brands that pay attention to environmental protection.
4. Other bio-based polymers:
In addition to PLA and plant fibers, there are other bio-based polymers, such as polyhydroxyalkanoates (PHA) and polybutylene succinate (PBS). These materials are characterized by strong biodegradability and can be quickly decomposed under different environmental conditions. PHA and PBS are often used to produce more environmentally friendly packaging bags, which can effectively avoid the pollution of traditional plastic bags to the environment.
The advantage of these materials is that they are not only biodegradable, but also can function under different environmental conditions to meet the transportation needs of different types of mail. For example, compostable bubble mailers use PHA materials, which can maintain the cushioning properties of bubble film while ensuring the degradability of packaging bags after use.
By using raw materials such as plant-based materials, polylactic acid, and recycled paper, these biodegradable mailers not only meet logistics needs in terms of functionality, but also can be quickly degraded after use to reduce environmental burden. As an eco-friendly poly mailer, they demonstrate the great potential of environmentally friendly packaging and also promote the packaging industry to develop in a greener and more sustainable direction.
