First of all, sanitary napkins are made from a variety of materials, including cotton, super absorbent polymers, and plastics. The materials used in them do not have a shelf life in the traditional sense, as they do not degrade or become unstable over time.
However, its expiration date is not based on the materials used in the product, but on the adhesive that sticks it to your underwear. Adhesives are usually made up of a variety of chemicals that degrade over time, causing it to lose its stickiness, which can lead to leaks or even fall off.
Different sanitary napkins have different shelf lives, ranging from one to five years. It is best to use it within the specified period to ensure maximum effectiveness and hygiene.
If you find that it does not stick to your underwear as it should, it is recommended that you replace it immediately. Continuing to use a poorly sticky one can lead to discomfort, leaks, and embarrassment. Therefore, it is crucial to check the expiration date on the packaging before purchasing a sanitary napkin.
It is also important to store it well to maintain its effectiveness and quality. To extend the shelf life of sanitary napkins, it is best to store them in a clean, dry container or drawer away from direct sunlight and heat sources. Exposure to high temperatures or high humidity can cause the adhesive to break down or the material to compress or deform, rendering it ineffective. It is also a good idea to keep the original packaging intact before use to protect them from dust and other contaminants.
