Manufacturers of sanitary napkins and paper diapers are basically processing or trading enterprises. They purchase raw materials, process them, shape them, print them, and sell them after packaging. Except for sales, quality risks may exist in every link.
The main raw materials of sanitary napkins and diapers are basically purchased from suppliers. Unless the diaper supplier has established a strict delivery inspection system, the quality risk in this link is the biggest. If the raw materials are not qualified, the hygienic products will not be qualified. Therefore, the control of the quality of raw materials is a key link in controlling the quality of finished products.
The main raw materials for the production of sanitary napkins and diapers are non-woven fabrics, fluff pulp, high-absorbency resins and toilet paper. Non-woven fabric is a kind of non-woven fabric, mainly used as the surface material of sanitary napkins and diapers.
The production of sanitary napkins wholesale and diapers is basically a process of processing and molding, which is a dry manufacturing process, and fluorescent whitening agents are generally only used in the wet manufacturing process. Therefore, the most likely possibility that sanitary napkins and diapers contain fluorescent whitening agents is none. It is caused by raw materials such as textiles, but the ultimate risk is borne by the sanitary napkin and diaper manufacturers(baby diaper supplier and adults diapers pants wholesale supplier).
Fluff pulp, high-absorbency resin, and toilet paper are the main absorbent materials for sanitary napkins and diapers. The liquid absorption capacity of these materials directly affects the liquid absorption capacity of the final sanitary napkins and diapers.
The commonly used high-absorbency resin is polyacrylic acid, and the acrylic monomer of synthetic resin is moderately toxic and severely corrosive. Its aqueous solution or high-concentration vapor has a strong irritating effect on the skin, eyes and respiratory tract, and can cause burns to the human body.
Therefore, if the resin contains excessive acrylic monomers, it will cause harm to the human body. These factors may cause the quality of sanitary napkins and diapers products.
The main risk of products such as sanitary napkins and sustainable disposable diapers in the processing and molding process lies in the control of sanitary indicators. The corresponding national standards stipulate that the sanitary indicators of sanitary napkins and diapers should comply with relevant regulations.
Relevant regulations stipulate the sanitary napkins and diapers and other products themselves and production environmental sanitation standards, disinfection effect biological monitoring and evaluation system standards and corresponding inspection methods, as well as raw materials and product production, disinfection, storage, and transportation process hygiene requirements.
The content of the relevant regulations is very rich, but only part of the indicators and microbiological indicators are tested in the daily sample test. Because sanitary napkins and diapers are often disinfected with ethylene oxide during the production process.
However, there are certain residues after ethylene oxide sterilization. These residues are harmful to the human body and corrosive to the skin, eyes, and respiratory tract. The quality risks of hygienic products caused by this should be taken seriously.
Due to the characteristics of sanitary napkins and diapers,like organic pull up diapers, adhesives are inevitably used in the processing process, and in order to beautify the appearance, the products are printed to varying degrees.
Since the printing inks currently used are mainly solvent-based inks, the inks contain volatile organic compounds, and the adhesives are basically organic substances and also contain VOCs. This is the reason why people feel pungent odors when they touch certain sanitary napkins and diapers.
The main components of VOCs are: hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons and nitrogenous hydrocarbons, which include: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, ester acids and petroleum hydrocarbon compounds, etc. With strong toxicity, it poses a great threat to people's health and also brings potential risks to product quality.
In order to meet the differentiated needs of consumers and expand market share, sanitary napkins and diapers manufacturers continue to innovate and develop personalized products.
By using functional materials or adding functional chemicals to produce hygienic products with special functions, such as antibacterial products(baby bath wipes), medicinal products(sanitary pads after delivery), or products with special aromas.
Innovation is the driving force for the development of an enterprise. However, since the establishment of quality standards cannot keep up with the speed of new product development, there are often situations where there is no standard to follow. The process of new products is often as a technical secret that outsiders cannot know, which brings difficulties to the supervision of product quality. At the same time, due to the immaturity of the new product technology, it will also bring about the quality risk of the innovation of hygienic products.
