Hong Kong is the first production base of Ruide sanitary products in the world, in 1982 Phoebe was born here, light and thin is the biggest feature of Phoebe diapers, it not only has good market results in Hong Kong and Macau, but also is a best-selling brand in Southeast Asian countries.
 
Ruide International is the first to launch the Phobe ultra-thin diaper, which uses a patented absorbent layer Megathin, which is an absorbent core with a slit that quickly absorbs urine while spreading evenly and locking it firmly into the inner layer of the diaper. The breathability of diapers is also related to the process and the structure of each layer, and it is not necessarily that the thinner the more breathable. In the actual use effect, the second sucking and shalting series are the lightest, the best absorption, and the price is the most affordable, with a single piece only 0.7-1.2 yuan. The ace ultra-thin series has the best air permeability, and the reference price of a single piece is 0.9-2.1 yuan.
 
China has reached the third and fourth generation in diaper core technology, while most foreign countries are still in the second generation. The completely different core structure is the biggest difference between local brands and foreign brands. The second-generation core uses fluff pulp mixed with SAP, which has strong absorption, but also has the problem of easy fault and lump, while the third- and fourth-generation composite core of non-woven mixed SAP has become the biggest competitiveness of Chinese brands by sacrificing part of the absorption performance to achieve lightness and thinness. The fourth-generation core is further partitioned on the basis of the third-generation core, which improves the anti-permeability performance, and the absorption speed and absorption volume are better than those of previous generations of diapers.
 
On the difference in the core structure of domestic and foreign brand diapers, in addition to the high cost of importing high-quality fluff pulp in China, the mainstream parenting concept at home and abroad is also different. In foreign countries, environmental protection and absorbency are often the first needs, while Chinese parents value comfort and breathability more. After years of application, the technology is mature, and the R&D, supply chain, and production equipment are all taking this route, with a large industrial scale and high input cost, and the possibility of transformation is extremely low in the case of no obvious shortcomings in the use of fluff pulp.
