"Light Sealed" refers to a method of protecting items from exposure to light, which can cause degradation or fading. This technique is commonly used in packaging for sensitive products, such as photographic materials, artworks, and medications. By using opaque or UV-blocking materials, the integrity and quality of the contents are preserved. In various industries, "Light Sealed" packaging is essential for maintaining the effectiveness of products. For example, cosmetics often utilize light-sealed containers to prevent chemical reactions that can occur when exposed to sunlight. This approach helps ensure that consumers receive products that are safe and effective.
