In medical facilities such as hospitals and clinics, a large amount of waste of various natures is produced every day. These medical wastes may contain pathogens, chemical pollutants or sharp objects. If not properly handled, they can easily become the source of disease transmission, posing a serious threat to medical staff, patients and even the public environment. Therefore, the standardized and safe disposal of medical waste is a crucial step.

Classification of medical waste bags.

Yellow garbage bags: This is the most common type of medical waste bag, used for collecting infectious and hazardous waste. For instance, used cotton swabs, gauze, disposable medical devices, surgical waste, culture media for pathogens, etc., may carry pathogenic microorganisms and pose a risk of spreading infectious diseases.

Red garbage bags: Used for collecting pathological waste. It mainly includes human waste, organs, tissues generated during surgeries or other medical treatments, as well as human tissues and pathological wax blocks after pathological sections.

Black garbage bags: In some hospital regulations, black bags may also be used to collect chemical and pharmaceutical waste, but more commonly, they are used to collect domestic garbage generated by hospitals (items not contaminated by patients' blood and body fluids).

The specific color coding must strictly follow local regulations and internal hospital rules.

Compared with ordinary plastic bags, biohazard disposable bags have extremely high requirements in terms of material, process and design to ensure their safety and reliability.



1. High density and puncture resistance: Biohazard garbage bags are typically made of brand-new high-strength polyethylene (HDPE or LDPE) materials, which feature extremely high toughness and tear resistance. Especially when used to hold damaging waste such as needles and blades, it is essential to ensure that the bag body is not punctured to prevent sharp objects from being exposed and causing occupational exposure risks.

2. Anti-seepage and sealing performance: The bag body is of uniform thickness and has excellent sealing performance. After encapsulation, it can effectively prevent the leakage of liquids, blood, tissues, etc., avoiding cross-contamination and environmental pollution.

3. Eye-catching printing and marking: The bag body is printed with clear medical waste warning signs and biological hazard warning signs. The colors are bright and not easy to fall off, which serves as a strong warning and reminds the staff to handle it with caution.
