👉 Shelf fluid, also known as packaging fluid or shelf-sealant, is a specialized liquid or gel applied to the surface of packaged goods, primarily in food and pharmaceuticals, to prevent moisture loss, contamination, and spoilage while also providing a protective barrier against physical damage. It ensures the product remains fresh and maintains its intended quality throughout storage and transportation. Shelf fluid typically contains ingredients like silicone oils, waxes, or polymers that adhere to the packaging material, creating a smooth, non-stick surface that enhances the shelf life of the product. This fluid is crucial for maintaining product integrity and consumer safety, especially for items sensitive to humidity or air exposure.
