One of the most important functions of packaging is to preserve and protect the quality of its contents. When it comes to external factors, exposure to moisture is one of the main causes of spoiled products, and one way to prevent this is through waterproof packaging.


The preservation of cosmetic materials and their ingredients depends highly on moisture protection. Many products – dry cosmetic products especially – are at risk of damage if they come into contact with water or steam. Waterproof packaging provides this protection by the material preventing any type of moisture from accessing the contents stored inside.


Waterproof fabrics are frequently used in the clothing industry, preventing water from seeping in but allowing water vapour to pass out and evaporate. Waterproof materials for the packaging industry, however, need to prevent water and water vapour from both seeping in and out, in order to protect both the packaged materials and the environment. Dry cosmetic products such as bronzers, powders and eyeshadows may become entirely unusable if damaged by water, highlighting the importance of a functional, waterproof packaging solution.


What Materials are Waterproof?

Waterproof materials used for packaging include many types of plastic, as well as glass. Glass in particular is a nonporous and impermeable material, making it an excellent choice for a waterproof packaging material.  Products stay completed protected from moisture , eliminating the risk of any interactions taking place with the product ingredients, and ensuring safe usage for consumers.


Plastic packaging materials, on the other hand, are a popular choice for waterproof packaging in the chemicals industry. PE and HDPE canisters are commonly used for packaging harmful liquids, when it’s essential for packaging to prevent the liquid contents from damaging or contaminating the environment and other products. The waterproof barrier of these materials offers protection to the stored liquid whilst protecting the environment from the liquid by preventing any moisture from passing in or out of the packaging.


Consider the Closure

Although waterproof packaging is effective, with the actual material being the primary barrier, the packaging also has to guarantee that the opening/closing used won’t cause any significant reduction in its overall waterproof quality. It’s therefore crucial to choose an opening/closure that ensures a complete waterproof function. Using waterproof materials in combination with airtight packaging guarantees a complete seal. The closure on airtight packaging seals the container perfectly, so that the contents has no possibility of coming into contact with the external moisture. The risk of moisture getting into the container is therefore not compromised by the closure, keeping the contents protected. For cosmetics products in particular, waterproof packaging with airtight closures ensure complete preservation for products to be safe to use on skin.

A great option for preserving and protecting products at risk from contact with moisture, waterproof packaging ensures your products remain as intended and entirely safe for use.
