There are several ways to make a plastic container waterproof, depending on the type of container and its intended use. For example, if you want to waterproof a storage tote, you can use clips, straps, or bungee cords to secure the lid. You can also tape the lid shut or purchase a tote with a gasket lid. Another option is to place the tote inside a larger waterproof bag or wrap it in cling plastic film. Alternatively, if you're looking to create a small waterproof container, you can upcycle plastic bottles by cutting them below the lid and sanding down the edges to create a smooth surface. You can then glue a plastic circle to the rim of the lid to make it waterproof. Additionally, you can use plastic drinking straws to create small airtight and waterproof containers by melting the ends with a heat source.

What You'll Learn
Use hot glue or super glue to seal the rim of the lid
Sealing the rim of the lid with glue is a straightforward and effective method to ensure your plastic container is waterproof. Hot glue or super glue are both suitable for this purpose, and the process is relatively simple.
Firstly, you will need to prepare the lid by ensuring it is clean and dry. Any residue or moisture on the lid can prevent the glue from adhering properly, so it is important to start with a clean surface. You may also want to sand the lid to create a rough texture, as this can help the glue bond more effectively.
Once the lid is prepared, you can begin by applying a thick bead of glue directly onto the rim of the lid. The thickness of the glue is important, as it will fill any small gaps or imperfections between the lid and the container, creating a tight seal. Be careful not to use too much glue, as you do not want it to overflow or create a mess.
After applying the glue, quickly place the lid onto the container, pressing down firmly and holding it in place for a few seconds to ensure the glue sets properly. If any excess glue has squeezed out from between the lid and the container, you can simply wipe or scrape it away.
Hot glue is a particularly good option for this method, as it dries quickly and can fill any small gaps effectively. Super glue is also a strong adhesive, but it may not fill gaps in the same way, so you will need to ensure the surfaces are smooth and well-prepared.
By using this method, you can be confident that your plastic container is well-sealed and protected from water ingress. This technique is simple, yet highly effective for ensuring your container is waterproof.

Wrap the container in plastic film
If you want to make a plastic container waterproof, one option is to wrap the container in plastic film. This method is simple and effective, and it can help to keep your belongings dry and protected. Here's a step-by-step guide on how to do it:
First, source some wide cling plastic film. This can be found at a U-Haul or moving supply store, or you may be able to find it at a hardware store. Make sure you get the type that is clingy and sticky, as this will help create a watertight seal.
Next, prepare your container by cleaning it and ensuring it is dry. Any residue or moisture on the container may affect the cling film's ability to stick and create a proper seal. So, take the time to wipe it down and ensure it is completely dry before proceeding.
Now, you can begin wrapping the container. Start at the bottom and work your way up, stretching the plastic film tightly as you go. Make sure there are no gaps or holes in the film, as these could allow water to enter. Overlap the layers of film for extra protection and to ensure that any potential holes are covered by another layer.
As you reach the top of the container, you may find it helpful to have someone assist you. Stretch the film over the top and smooth out any wrinkles or creases. Ensure that the film is tightly sealed around the rim of the container to prevent any water from entering.
Finally, check your work by giving the container a once-over. Look for any areas where the film may not be securely adhered to the container, and smooth out any bubbles or wrinkles that could potentially allow water to enter.
By following these steps, you can effectively waterproof your plastic container using plastic film. This method is a quick and easy solution for keeping your belongings dry and protected from moisture.

Melt the end of a plastic straw to create a seal
Plastic straws can be used to create simple, waterproof containers. The process is straightforward: the ends of the straws are held with needle-nose pliers about 2-3mm away from the end of the straw. Then, a lighter is used to carefully melt the end of the straw, sealing it shut. You can also use an iron to achieve the same result. This method is ideal for storing small items such as medication, ointments, or even spices.
To create a waterproof seal, hold the end of the straw with needle-nose pliers, leaving a small portion protruding. This protruding part will be melted to create a seal. Use a lighter to carefully melt the plastic, forming a tight seal. You can also use an iron by placing the end of the straw between two layers of parchment paper and working the hot iron over it to melt the plastic.
For added precision, cut a tiny 'V' notch at the sealed end of the straw with a sharp knife. This will allow for an easy tear when opening the container. This method is especially useful for creating single-use containers for items like antibiotics or ointments.
The versatility of straws as containers is evident in their ability to store both solids and liquids. For instance, you can use a straw to store ointment by squeezing a small amount into the straw and then sealing the end with the melting technique described above. This ensures that the ointment remains clean and does not ooze out during the sealing process.
Overall, melting the end of a plastic straw to create a waterproof seal is a simple and effective method for creating small, portable containers for a variety of items. It is a useful technique for camping, hiking, or any situation where you need to keep items dry and secure.

Use a wet bag or canoe sac to put inside your container
If you're looking to make a plastic container waterproof, one option is to use a wet bag or canoe sac as an inner lining. This is a popular method for campers and outdoor enthusiasts, as it ensures the contents of the bag stay dry.
Wet bags or canoe sacs are designed to keep their contents dry, or to prevent any liquid contents from leaking out. They are usually made of robust, flexible PVC material, which can withstand knocks and bumps without sustaining damage or scuffing a hole in the bag. These bags are also available in lightweight options, which are perfect for camping and hiking. The bags are versatile and can be used for a range of outdoor activities, including kayaking, canoeing, sailing, and even on the back of a motorbike.
When using a wet bag or canoe sac, it's important to ensure the bag is properly sealed. Most bags have a strong top closure, and some have an extra plastic stiffening blade at the top, which helps to roll the bag tightly and keep it watertight. It is recommended to roll the bag down 3 to 4 times and then clip it together at the top. Before using the bag, it's a good idea to test it for any leaks by filling it with water and ensuring no water escapes.
To make the most of your wet bag, consider using different-sized bags to separate items and keep them organised. For example, you can use smaller bags for items you want to keep dry, such as electronics, fire-starting tools, spare base layers, and medical kits. You can also use larger bags for items like sleeping bags, pillows, and clothing. By using a combination of bag sizes, you can tailor the storage to your specific needs. Additionally, utilising a range of colours can help you identify the contents of each bag at a glance.

Cut and sand down a plastic bottle to make a container
To make a plastic container waterproof, you can cut and sand down a plastic bottle to create a new container. This is a great way to repurpose plastic bottles and create a useful item. Here's a step-by-step guide to the process:
Prepare the Bottle:
Start by choosing a sturdy plastic bottle with a quality cap, such as a 16oz water bottle or an applesauce container. Remove any labels and clean the bottle thoroughly with dish soap and warm water. Let the bottle air dry completely before proceeding.
Mark the Cut Line:
Use a permanent marker to mark the cut line on the bottle. Decide on the size and shape of your desired container, and mark the areas that need to be cut accordingly. You can use a non-mechanical measuring tape to ensure straight lines, or draw more complex shapes as needed.
Cut the Bottle:
Place the bottle on a thick piece of wood, at least 1 inch (2.5 cm) thick, to use as a cutting board. Hold the bottle securely with one hand while using the other hand to cut. You can use an X-Acto knife, a bandsaw, a hacksaw, or a sharp kitchen knife to carefully cut through the marked line. For smaller bottles with thin plastic, scissors can also be used.
Sand the Edges:
Once you've made the initial cut, use scissors or sandpaper to smooth out the edges. Remove any splinters or sharp spots by trimming 1-2 millimetres from the cut edge. Sand the plastic until you create an even and smooth surface. If you don't have sandpaper, you can even rub the edge against a concrete surface.
Create a Waterproof Seal:
To make your new container waterproof, you can use a variety of methods. One option is to run a thick bead of hot glue or super glue around the rim of the lid. Press a plastic circle or the lid of another bottle onto the glue to create a watertight seal. Any excess glue can be wiped away. Alternatively, you can use silicone caulk or duct tape to seal the container, ensuring no water can enter through the lid.
With these steps, you can transform a simple plastic bottle into a waterproof container, perfect for storing small items or even creating a unique bird feeder for your backyard.
