Because odor is a kind of overall feeling formed by the combination of various volatile substances, diapers may bring odor sources from production to packaging to logistics and transportation to the market.
The production process includes the relevant raw materials of the diaper, and the production machine environment carries volatile substances. In terms of packaging, the current production capacity of diaper manufacturers is different. Manual packaging and automatic packaging are uneven, but most of the cases are still hand-packed by the packaging workers. It is easy to manually bring in volatile substances.

In the transportation, storage and sales links, FMCG has a wide range of sales and numerous channels. The storage period is long under the line and the environmental conditions are ever-changing. The degradation of the materials themselves and the volatilization of small molecules may occur at any time.


From the raw material itself carrying the odor source, to the artificially introduced odor source, and the passively accepted odor source in the environment; a variety of odor-containing volatile substances are stored in a sealed packaging environment for a long time, internal volatilization, cross reaction, comprehensive formation The ultimate integrated odor of the diaper product.



As a development and production organization of diapers, when the hard conditions such as fixed production, transportation and sales channels cannot be changed, more should be taken from the raw material point of view to minimize the source of volatile substances that are naturally carried after the diaper products are molded.

 

At present, the commercially available diaper products are non-woven fabrics, printing films, hot melt adhesives, high-molecular main raw materials and packaging auxiliary materials, and these raw materials are more or less brought into the odor source.


 

According to the category: 

the odor of urine gelatin, packaging bag, room temperature glue, composite paper and base film combined accounted for 70% of the total odor, and the single ratio was more than 15%, which was the main source of odor.
