As a specially designed sanitary product, a sick bag has significantly different functions from ordinary bag products. Compared with common plastic bags, handbags or garbage bags in daily life, vomit bags have targeted optimization in terms of materials, structure and usage scenarios.
First of all, the core function of a sick bag is to cope with sudden vomiting needs, so its material is usually made of a composite film that is impermeable and odor-proof to ensure that the liquid does not overflow and isolate the spread of odor, avoiding secondary pollution to the user and the surrounding environment. Ordinary shopping bags or packaging bags often use single-layer plastic or paper materials, lack leak-proof design, and cannot withstand liquid pressure.
Secondly, the opening design of the vomit bag often adopts a wide-edge roll-up structure, which can be quickly unfolded and used, and can achieve efficient sealing. This convenience is particularly important in emergency scenarios such as transportation vehicles and medical institutions. Ordinary garbage bags mostly use a flat-mouth design, which needs to be manually knotted and closed, and the operation efficiency is low. In addition, the portability of vomit bags has been specially considered. They are usually stored in a folded state in specific locations such as aircraft seat back pockets and medical first aid kits. They are small in size but can be quickly unfolded into a storage device with sufficient capacity when needed.
In contrast, the functions of ordinary plastic bags are generalized and it is difficult to meet the hygienic treatment needs in emergency situations. It is worth mentioning that some high-end vomit bags also add deodorizing particles or antibacterial coatings, and this hygienic protection performance far exceeds that of conventional bag products. From the perspective of usage scenarios, vomit bags mainly serve individual health protection in specific environments. Their existence highlights the value of humanized design, which is the social significance that ordinary plastic bags do not have simply as containers for goods.
