Actually the basic components of baby diaper are surface, back sheet, core, leak guards, tape and elastic waist band.
1.Surface: regularly it is hydrophilic non-woven to allow the liquids to flow into the diaper core. However, it could be replaced with natural plant-based fiber, like in our company we use 100% bamboo fiber which is biodegradable and naturally anti-bacterial.
2.Back sheet: common nappies’ back sheet is made of PE or cloth-like film to prevent the liquids from leaking out of the diaper. The back film of our bamboo baby diaper is two layers of bamboo fiber to avoid leaking while stay breathable.
3.Core: SAP and fluff pulp are mixed to build the absorbing core.
SAP is super absorbent polymer. To be honest there is compostable SAP in the world, but the absorbency performance is not stable. So the regular SAP still dominates the market. The SAP in our biodegradable baby diaper is Sumitomo that is the best SAP manufacturer in the world. Fluff pulp is used in the construction of the core, it gives integrity and absorbing capacity to the diaper. Coming from pine tree allows it could be decomposed under composting.
4.Leak guards: hydrophobic PLA non-woven fabric for leak guards. PLA is a new type of biodegradable material, made from starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature after use, and finally carbon dioxide and water are generated without polluting the environment. This is very beneficial to environmental protection and is recognized as an environmentally friendly material.
5.Tape: In premium diapers, Velcro type materials have been used to provide mechanical grip, it is also known as the “hook tape” which is not compostable while is the most secured fastening material. The tape we used in bamboo nappies is from 3M company, the best supplier in this field.
6.Waist band: consist of undecomposed spandex to improve the fit of the diaper.
In short, 60% of our bamboo baby diaper is biodegradable. Also it has already been exported to North America and Europe. Repurchase rate is over 90%.
