How to Make Waterproof Cardboard: 7 Proven Methods for 2025

When it comes to packaging, waterproof cardboard is a game-changer. Whether you’re shipping products to clients or storing items in your warehouse, you want to ensure that your goods remain safe from water damage. At Discounted Packaging, we understand the importance of waterproof packaging solutions. In this article, we’ll explore 7 proven methods for making waterproof cardboard that you can use in your business in 2025.

Method 1: Coating with Waterproofing Spray

One of the easiest and most effective ways to make waterproof cardboard is by coating it with a waterproofing spray. There are many types of waterproofing sprays available on the market, from silicone-based to acrylic-based. Simply cut your cardboard to the desired size, spray the coating evenly, and let it dry before using it for packaging. This method is great for protecting items from humidity and light water exposure.

Method 2: Applying a Waterproofing Film

Another effective method for making waterproof cardboard is by applying a waterproofing film. This film is available in different thicknesses and can be cut to size according to your needs. Simply apply the film to the cardboard using a backing sheet, and you’re good to go. This method is ideal for protecting items from heavy water exposure and extreme weather conditions.

Method 3: Using Waterproof Cardboard Sheets

Some companies, like Discounted Packaging, offer pre-manufactured waterproof cardboard sheets. These sheets are designed to provide excellent protection against water and humidity. They’re made from high-quality materials and are easy to use. Simply cut the sheet to size, and you’re ready to start packaging. This method is great for businesses that require a large quantity of waterproof cardboard for their packaging needs.

Method 4: Applying a Waterproofing Liquid

Applying a waterproofing liquid is another effective method for making waterproof cardboard. These liquids are designed to penetrate the cardboard fibers and provide a strong waterproof barrier. Simply cut your cardboard to size, apply the liquid evenly, and let it dry before using it for packaging. This method is great for protecting items from heavy water exposure and extreme weather conditions.

Method 5: Using Waterproof Tape

Waterproof tape is a great alternative to traditional waterproofing methods. It’s easy to use and provides a strong seal against water and humidity. Simply apply the tape to the cardboard, making sure to seal any gaps or edges. This method is great for protecting small items or for use in emergency situations.

Method 6: Creating a Waterproof Box

Creating a waterproof box is a more extensive method for making waterproof cardboard. This involves cutting the cardboard to size, applying a waterproofing liquid or spray, and then assembling the box. This method is great for protecting large or heavy items and provides excellent protection against water and humidity.

Method 7: Using a Waterproof Cardboard Box

Finally, using a pre-manufactured waterproof cardboard box is a simple and effective solution for making waterproof cardboard. These boxes are designed to provide excellent protection against water and humidity and are easy to use. Simply fill the box with your items, seal the box, and you’re good to go. This method is great for businesses that require a large quantity of waterproof cardboard for their packaging needs.
