What kinds of coffee packaging materials are available?
Kraft paper, PLA, aluminum plating and plastic composite materials are more commonly used now; among them, kraft paper and PLA materials are biodegradable and recyclable materials.
1. Kraft paper
Kraft paper is usually yellow-brown, with high strength and good toughness, and has high tear strength, rupture work and dynamic strength. The quantitative is generally 80-120g/m², and there are two forms of roll paper and flat paper, and there are also differences such as single-sided glossy, double-sided glossy and striped. The paper has a tough texture and high tear resistance, and can withstand large tension and pressure without breaking. Kraft paper is a degradable material. The raw material is mainly wood fiber, which can be recycled and more environmentally friendly. The implementation of the current plastic restriction order has made kraft paper more widely used in the packaging field.
2. PLA material
PLA, or polylactic acid, is an emerging ecological and environmentally friendly synthetic fiber made from recycled starch raw materials (such as corn, wheat, etc.) through fermentation to generate lactic acid, and then polymerized and spun.
PLA material has good biodegradability. After being discarded, it can be decomposed into carbon dioxide and water by microbial action in nature, which is harmless to the environment.
What are the benefits of sustainable packaging bags?
1. Reduce resource consumption
Traditional packaging bags are mostly made of non-renewable resources such as petroleum-based plastics, while sustainable and environmentally friendly packaging bags are usually produced using renewable resources (such as plant fibers) or recycled materials, which can significantly reduce dependence on limited natural resources. For example, packaging bags made of bamboo fiber, which grows quickly and has strong renewable capacity, greatly reduce the consumption of non-renewable resources such as oil compared to traditional plastic packaging bags.
2. Reduce pollution emissions
Sustainable and environmentally friendly packaging bags produce fewer pollutants during the production process. The production of traditional plastic packaging bags will emit a large amount of greenhouse gases and harmful chemicals, while the production process of environmentally friendly packaging bags, such as paper packaging bags, will also have certain carbon emissions, but relatively much less.
3. Promote social sustainable development
The use of sustainable and environmentally friendly packaging bags is an important manifestation of social sustainable development. It helps to promote the entire society to develop in a greener and low-carbon direction, and achieve coordinated progress in economy, environment and society. By reducing the negative impact on the environment, it creates a better living environment for future generations.
