One of the most important — and often overlooked — aspects of choosing the right sanitary napkin is the raw material. The materials used in a sanitary napkin can have a major impact on its overall performance, including everything from absorbency to comfort.
In this guide, we’ll take a closer look at some of the most commonly used raw materials in sanitary napkins, as well as their pros and cons. With this information, you can make a more informed decision about which type of sanitary napkin is right for you.
What is a sanitary napkin?
A sanitary napkin, also known as a sanitary towel, is an absorbent item used by women during menstruation to soak up blood. Sanitary napkins are made from a variety of materials, the most common being cotton, rayon, and cellulose.
The materials that make up a sanitary napkin are designed to perform three functions: they must be able to absorb menstrual fluid, prevent leaks, and be comfortable to wear.
The absorbent core of a pad is usually made up of wood pulp fluff, which is then surrounded by a layer of polymer gel that helps to lock in the fluid. The entire core is then enclosed in a textile backing, which acts as a leak-proof barrier. The pads are then covered in a topsheet, which is often made of soft, fluffy material like cotton or rayon, to make them more comfortable to wear.
The first step in production is choosing the right materials. The two main types of materials used in sanitary napkins are cellulose and synthetic polymer. Cellulose, which is derived from plants, is the most popular type of material used in pads. It is soft, absorbent, and comfortable to wear. Synthetic polymer, which is derived from petroleum, is also a popular type of material used in pads. It is less absorbent than cellulose but has a longer shelf life.
The next step in production is to add the absorbent materials to the pad. The amount of absorbent material added to the pad depends on the type of pad being made. The most common types of pads are light, medium, and heavy flow pads.
After the absorbent materials have been added to the pad, it is time to add the adhesive backing. The adhesive backing helps to keep the pad in place during wear.
Finally, the pads are packaged and sent to stores for purchase.
The market for sanitary napkins
The global sanitary napkin market was estimated to be valued at over US$ 13 billion in 2020. The market is expected to grow at a CAGR of over 5% during the forecast period of 2020-2025. The market is driven by the growing awareness of personal hygiene, rising disposable incomes, and the availability of a wide range of products.
The market for sanitary napkins is ever-growing with new products being introduced constantly. As a result, there is a lot of confusion about what raw materials are used in making sanitary napkins and which ones are best. In this guide, we will clear up some of that confusion and help you make an informed decision about the products you use.
Sanitary napkins are made from a variety of materials, but the most common are cotton, rayon, polyester, and cellulose. Cotton is by far the most popular material used in making sanitary napkins. It is soft, absorbent, and comfortable to wear. However, cotton does have some drawbacks. It is not as absorbent as some of the other materials and it can cause skin irritation in some women.
Rayon is another popular material for making sanitary napkins. It is made from wood pulp and is very absorbent. Rayon is also soft and comfortable to wear, but it can shrink when wet and may not be as durable as some of the other materials.
Polyester is a synthetic material that has become increasingly popular in recent years. It is very absorbent and durable, but it can be uncomfortable to wear due to its synthetic nature.
Cellulose is a natural material that is derived from plant fibers. It is very absorbent and comfortable to wear, but it can be more expensive than some of the other materials.
Sanitary napkins are an essential product for millions of women around the world, and the market is growing every year. The global sanitary napkin market is expected to reach $13.8 billion by 2022, a compound annual growth rate of 6.9%.1
With this level of market growth, it’s no surprise that there is an increasing demand for sanitary napkin raw materials. In order to meet this demand, manufacturers are always on the lookout for new and innovative materials that can be used in their products.
One of the most important raw materials in a sanitary napkin is the absorbent core. This is what actually holds the blood and other fluids during menstruation. The most common material used for absorbent cores is cellulose fiber, which is derived from wood pulp. Other options include superabsorbent polymers (SAPs), which are synthetic materials that can absorb large amounts of fluid. SAPs are usually more expensive than cellulose fiber, but they offer some advantages in terms of absorbency and dryness.2
Another important raw material in sanitary napkins is the topsheet. This is the layer that comes into contact with the body, and it needs to be soft, comfortable, and highly breathable. The most popular material for topsheets is polyethylene (PE), which is a type of plastic. PE topsheets are usually coated with another material, such as nonwoven fabric, to make them even more comfortable and effective.3
The backing sheet is another key component of a sanitary napkin. This sheet helps to keep the pad in place and provides additional leak protection. The most common material used for backing sheets is polypropylene (PP), which is a type of plastic.4
Finally, adhesives are often used to keep sanitary napkins in place during wear. These adhesives need to be strong enough to stay in place, but gentle enough not to cause skin irritation. One popular material for adhesives is acrylate, which is a type of synthetic rubber.5
As you can see, there are many different types of raw materials used in sanitary napkins. manufacturers are always on the lookout for new materials that can offer improved performance or lower costs. With the market for sanitary napkins expected to continue growing in the years ahead, there will be ample opportunity for innovation in this space
The future of the sanitary napkin market
The global sanitary napkin market is expected to grow at a CAGR of 6.8% from 2019 to 2024. The market is driven by the rising awareness of feminine hygiene, the growing disposable income, and the availability of a wide range of products. However, the high cost of raw materials is restraining the market growth.
Innovation in the sanitary napkin market is being driven by a number of factors, including the ever-growing global population of women in the childbearing years, the rise in disposable incomes, and changing social norms and attitudes towards menstrual hygiene. In developed markets, such as North America and Europe, where women have historically been the early adopters of new products and technologies, manufacturers are focused on introducing new product formulations and designs that offer greater comfort, absorbency, and leakage protection. In developing markets, where there is a large untapped potential for growth, manufacturers are focused on expanding their distribution channels and reaching out to new consumers through education and awareness campaigns.
Today, an eco-friendly and biodegradable sanitary napkin is something that every woman looks for while purchasing a sanitary napkin. With the increase in awareness about the harmful chemicals present in conventional sanitary napkins and its disastrous effect on the environment, the global sanitary napkin market is shifting its focus towards sustainable and biodegradable products.
In order to make a biodegradable sanitary napkin, manufacturers are using natural materials such as bamboo, cornstarch, and organic cotton. These materials are not only eco-friendly but are also soft and comfortable to use. Bamboo is one of the most popular raw materials used in the manufacture of sustainable sanitary napkins. Bamboo is a fast-growing grass that does not require the use of pesticides or fertilizers for its growth. It can absorb three times more carbon dioxide than trees and produces 30% more oxygen than trees. Bamboo is also anti-bacterial and anti-fungal in nature, which makes it an ideal material for use in sanitary napkins.
Cornstarch is another popular raw material used in eco-friendly sanitary napkins. Cornstarch is a renewable resource that can be derived from corn kernels. It is biodegradable in nature and does not pollute the environment like conventional plastic materials. Cornstarch absorbent pads are as equally efficient as plastic pads but are much better for the environment.
Organic cotton is yet another raw material that is being increasingly used in sustainable sanitary napkins. Organic cotton is grown without the use of harmful pesticides or fertilizers, which makes it safe for both the environment and your skin. Unlike conventional cotton pads, organic cotton pads do not contain any toxins or chemicals that can cause irritation or allergic reactions.
