Johnson & Johnson invented the Band-Aid product in the early 20th century and subsequently introduced it to the market under the brand name "Bangdi". Bangdi's market share in the band-aid market has long been the world's first, and the word "Bangdi" has almost become synonymous with band-aids. In the U.S. domestic market, Bondy's product concept and manufacturing process are at the top level, among which the HYDRO SEAL band-aid uses liquid seal technology, which focuses on super waterproof performance, and the other SKIN-FLEX skin elastic band-aid uses cross-fiber technology, which can dry quickly after touching water, prevent water seepage, and is quite good in durability and comfort.
 
Relatively speaking, the products sold by Bangdi in the Chinese market are relatively mediocre as a whole, and the main Benzalkonium chloride Patch, breathable Band-Aid and transparent waterproof Band-Aid are technically inferior to Neshikang, but as the most well-known Band-Aid brand in China, Bangdi is still the first choice for many consumers when buying.
 
One of the most recommended is Bangdi's transparent waterproof bandage, which has poor adhesion performance compared to Neshikang, and needs to be replaced frequently when used. However, Bangdi Band-Aid is more convenient to buy, and the average price of a single sheet is only about one yuan, which is still a good choice when it is urgent.
 
Benzalkonium chloride is the most well-known band-aid in China, which adds benzalkonium chloride as a disinfectant on the basis of elastic cloth band-aids, which can play a role in bacteriostatic and sterilization. The breathable band-aid is made of non-woven fabric and hot-melt adhesive paste, which is lighter and more breathable than benzalkonium chloride patch, and is more suitable for sensitive skin.
 
Due to the large number of counterfeit Band-Aid products of Bangdi, consumers should pay attention to distinguish between them when purchasing, and the registered trademark of Bangdi should be "Bangdi" instead of "Bondi".
