Waterproofing Plastic Totes: Easy And Effective Techniques

how to waterproof a plastic tote

Plastic totes are a great way to store items and keep them dry, especially in wet environments. However, not all plastic totes are created equal, and some may be more water-resistant than waterproof. To ensure your belongings stay dry, you may need to take extra steps to waterproof your plastic tote. This is especially important if you plan to use it in moist environments or if there is a risk of water damage. In this guide, we will explore the different ways to waterproof a plastic tote, from choosing the right materials and construction to sealing leaks and adding extra protection.

Use a rubber strip to seal the lid

To waterproof a plastic tote, one method is to use a rubber strip to seal the lid. This method is useful if you are concerned about water seeping in through the crevices between the lid and the bin. Rubber strips are easy to install and come with adhesive backings, so all you need to do is stick them onto the lid.

There are a variety of rubber strip materials to choose from, each with its own advantages. These include closed cell sponge rubber, EPDM closed cell sponge rubber, silicone closed cell sponge rubber, neoprene closed cell sponge rubber, and blended closed cell sponge rubber.

When selecting a rubber strip, consider the specific needs and conditions of your plastic tote. For example, if your tote is exposed to varying temperatures, you may want to choose a material that can withstand a range of climates. Additionally, ensure that the rubber strip you choose is compatible with the plastic material of your tote to ensure a strong and durable seal.

Before applying the rubber strip, it is important to clean the surface of the lid to ensure that the adhesive sticks properly. Remove any dirt, oil, or residue, and allow the surface to dry completely. Once the rubber strip is adhered to the lid, press down firmly along the length of the strip to secure it in place.

By using a rubber strip to seal the lid of your plastic tote, you can create an airtight and watertight barrier, protecting the contents of your tote from moisture and potential water damage.

Wrap the tote in plastic film

Wrapping a tote bag in plastic film is an effective way to waterproof it. Rolls of wide cling plastic film can be purchased from a U-Haul or moving supply store. This film can then be wrapped around the entire tote bag to ensure that it is fully waterproof.

To wrap the tote bag in plastic film, start by placing the bag in the centre of the plastic film. Then, bring the edges of the film up and over the bag, covering it entirely. Smooth out any air bubbles and ensure that the film is tightly wrapped around the bag. Finally, secure the plastic film in place by using tape or adhesive.

Another way to wrap a tote bag is by using the Furoshiki method, which involves using a square piece of fabric. Place the tote bag in the centre of the fabric and gather the corners of the fabric over the bag. Then, tie the fabric together with ribbon or twine at the top. A knot or bow can also be made on top of the bag. This method adds a personal and decorative touch to the tote bag.

Additionally, transparent adhesive film can be used to protect the tote bag. This method involves adding a layer of transparent adhesive film over the tote bag, providing both protection and decoration. This option is also eco-friendly, as it reduces waste by reusing materials.

Use a wet bag inside the tote

If you're looking to waterproof a plastic tote, one effective method is to use a wet bag inside the tote. This is a simple and inexpensive solution that can keep your belongings dry, especially if you're camping or involved in other outdoor activities.

Wet bags are typically made from waterproof materials like PVC, vinyl, or polyethylene, which are reliable for moisture protection. When choosing a wet bag, look for one with welded or heat-sealed seams, as stitched seams may leave tiny holes that can let water in, making the bag only water-resistant. Additionally, a zipper closure can further enhance the waterproof qualities of the bag.

When using a wet bag inside your plastic tote, ensure that the bag is large enough to fit comfortably inside with some room to spare. You don't want it to be too tight, as this may put pressure on the seams and increase the risk of leaks.

For added protection, you can also consider using a waterproof spray or seam sealer on the inside of your plastic tote. This will help to fill in any tiny holes or crevices that water could potentially seep through. However, keep in mind that this may discolour the plastic, so test it on a small area first if you're concerned about appearance.

By combining a wet bag with some additional waterproofing measures, you can effectively waterproof your plastic tote and keep your belongings safe and dry.

Seal the tote with bungee cords

To seal a plastic tote with bungee cords, you must first ensure that the tote is adequately protected from water. This can be done by adding a rubber strip to the top of the bin where the lid attaches. The crevice between the bin and the lid is the most vulnerable point of access for water to enter, so it is important to address this area. There are several different types of rubber strip materials to choose from, including closed-cell sponge rubber, EPDM closed-cell sponge rubber, silicone closed-cell sponge rubber, neoprene closed-cell sponge rubber, and blended closed-cell sponge rubber. Each type of material has unique advantages, so be sure to choose one that best suits your needs. Most rubber strips have adhesive backings, so all you need to do is stick them onto the lid.

Once the rubber strip is in place, you can use bungee cords to hold the lid securely in place. Bungee cords are an excellent choice for this because they are stretchy and can be adjusted to fit snugly around the tote. When using bungee cords, it is important to ensure that they are properly secured to avoid any accidents or damage to your belongings. Check and double-check that the cords are tightly fastened and that the lid is held firmly in place.

If you are cutting the bungee cords to a specific length, be sure to seal the ends to prevent them from unraveling over time. You can do this by tying off the ends or using any other suitable method. Additionally, if you have old or worn-out bungee cords, use your best judgment to determine if they are still safe to use. Always follow the directions provided with new bungee cords, and do not overload them with heavy items.

By combining the rubber strip with the bungee cords, you can effectively waterproof your plastic tote and ensure that your belongings stay dry and protected.

Sand and seal leaks with glue

To repair a leak in a plastic tote, you can use a variety of adhesive-based solutions, such as plastic glue, epoxy, or silicone sealant. Before applying the adhesive, it is important to prepare the surface of the plastic tote properly to ensure a strong and durable bond.

Firstly, identify the source and type of leak. Clean the area to be repaired with a damp cloth to remove any dirt or debris. Once the area is clean and dry, lightly sand the surface to create a rough texture that will help the adhesive bond better to the plastic. After sanding, wipe the surface again with a cloth to remove any dust or residue.

If you are using a two-part adhesive, such as the Loctite Plastics Bonding System, apply the surface activator to both surfaces and allow it to dry before proceeding with the adhesive. Follow the manufacturer's instructions for the specific adhesive you are using, as application methods may vary.

Apply the adhesive to the prepared surfaces according to the manufacturer's instructions. Press the surfaces together firmly and hold them in place for a few seconds to ensure a strong bond. If necessary, use clamps or weights to hold the surfaces together while the adhesive cures.

Allow the adhesive to cure completely before using the plastic tote. The curing time will vary depending on the type of adhesive used, so refer to the manufacturer's instructions. Once the adhesive has cured, your plastic tote should be properly sealed and waterproof.
