　　Finding a reliable biodegradable milk tea bag involves considering several factors to ensure the product meets your quality, sustainability, and usability requirements. Here¨s a guide to help you find the best options.Gold and silver are not as good as clear waters and green mountains. This is an environmental protection slogan put forward in recent years. When you order milk tea at home or in the office, you will get a packaging bag. A small packaging bag may not have any impact on the environment, but when people gather together, so many people order milk tea every day. Over time, the pollution caused by this plastic milk tea bag to the environment is still very serious, because ordinary Plastic can exist in nature for hundreds of years. If it is burned, it will also produce dioxins and other pollutants, causing serious damage to the environment.Actually, it’s not just this reason, biodegradable dog poop bags Its own advantages are also obvious, and it is normal for the market to perform well. https://biodegradable-gd.com

　　For the sake of environmental protection, the country has strictly restricted the production and sale of disposable plastic products such as plastic shopping bags since January 1, 2021, referred to as the “Plastic Ban”. As a result, supermarkets, restaurants, milk tea shops and other places have replaced plastic shopping bags with biodegradable bags to meet environmental protection requirements.

　　Among the solutions to replace plastic products, biodegradable materials have attracted everyone’s attention. Because the raw material of biodegradable milk tea bags, polylactic acid PLA, comes from plants such as corn and potatoes, and the source of raw materials is very environmentally friendly and natural. After use, biodegradable milk tea bags can be degraded into carbon dioxide, water and other substances in the landfill in about 180 days. They will not become “white garbage” like plastic bags and pollute the environment. With the implementation of the plastic ban, many milk tea shops have assumed the responsibility of environmental protection and have replaced plastic bags with compostable milk tea bags.

　　Therefore, when purchasing biodegradable products, you must carefully identify them. Here are some simple identification tips:

　　1. Choose products from large manufacturers, which are more reliable and reduce the risk of buying by mistake.

　　2. Read the ingredient description. When purchasing biodegradable milk tea bags, we can ask the manufacturer about the ingredients of the bags, which are generally polylactic acid (PLA), polyadipate (PBAT), and starch. Others such as PE+starch are pseudo-degradable. Relevant documents stipulate that degradable materials cannot contain plastic components such as PE, PP, PVC, and PET. Products such as PE+starch and PE+photooxidant are pseudo-degradable and need attention.

　　To find a reliable compostable milk tea bag, focus on verifying the materials, assessing environmental impact, evaluating quality, and considering brand reputation. By doing thorough research and possibly testing samples, you can ensure you choose a product that meets your needs while contributing to environmental sustainability.We are both victims and beneficiaries of environmental protection. For environmental protection, we can start with small things around us, starting with using one less plastic shopping bag and one less plastic straw.
