There are many ways to make a lid for a plastic container. One way is to use plastic wrap and a rubber band. Cut a piece of plastic wrap slightly larger than the opening of the container, place it on top, and secure it with a rubber band. Another method is to use a silicone sealant or foam weather stripping adhesive to create an airtight seal. You can also use Vaseline on the container before putting on the lid to achieve an airtight seal. If you're looking for a quick fix, you can use plastic packaging with hot glue around the edges to secure it to the container. For a more natural look, consider using cork or wooden disks cut to size and glued together.

What You'll Learn
Using plastic wrap and a rubber band
Start by cutting a piece of plastic wrap that is slightly larger than the opening of your container. Ensure that the plastic wrap is smooth and free of any tears or creases. Place the plastic wrap over the opening, centering it as much as possible.
Next, take a rubber band and stretch it around the rim of the container, securing the plastic wrap in place. Make sure the rubber band is tight enough to create a good seal, but not so tight that it distorts the shape of the container or tears the plastic wrap.
If needed, you can add an extra layer of plastic wrap for added security. Simply repeat the process by placing another piece of plastic wrap over the first layer and securing it with another rubber band. This extra layer can provide a stronger seal and is especially useful if you're storing liquids or items that need to be kept fresh.
When using this method, it's important to consider the contents of your container. While plastic wrap and a rubber band can create a functional lid, it may not be as secure as a traditional lid for items that need to be completely sealed. For liquids, it's best to use a container with a matching lid or consider using a different sealing method.
Additionally, you can customise your makeshift lid by using coloured plastic wrap or adding labels to the plastic wrap. This can be especially useful if you're using multiple containers and want to colour-code or label the contents for easy identification.

Buying a cork with the right dimensions
When buying a cork with the right dimensions, it is important to first understand the inner diameter of the container. The inner diameter of the container will determine the size of the cork you need to buy.
Corks come in various sizes, and the size is usually indicated by a number. For example, corks can come in sizes #7, #8, #9, and #10, with the number indicating the diameter of the cork. The higher the number, the larger the diameter. So, for a standard 750 ml wine bottle with a 3/4 inch opening, a #7, #8, or #9 cork would be suitable, depending on the type of wine bottle corker you have.
If you are looking for a cork for a plastic container, you may want to consider a cork with a diameter of 18-24 mm, which is suitable for plastic soda bottles. You can also find corks designed for specific purposes, such as synthetic corks for thick, heavy champagne bottles, or plastic wine stoppers for port.
It is important to note that the shape of the cork can also be a factor. For larger openings, a tapered cork or a rubber stopper with a bottom diameter slightly smaller than the opening may be a better option than a straight cork. Additionally, consider the method of insertion. Some corkers use a funnel design to compress the cork, which may cause issues with larger corks, so caution is advised.

Using a plastic plant-pot saucer
Plastic plant-pot saucers are an excellent option for creating a lid for a plastic container. They are inexpensive, lightweight, strong, and come in various sizes and colours. You can find them at hardware stores or plant supply kiosks in supermarket parking lots.
To use a plastic plant-pot saucer as a lid, start by flipping it over to ensure it fits securely on top of your container. If the saucer has a central drainage hole, you can cover it with tape or fill it with a small amount of silicone or adhesive putty to create a tight seal.
When selecting a saucer, consider the diameter of your container. A saucer with a diameter of 28 cm or more should fit most containers. It's okay if the size isn't an exact match, as the rim of the saucer can sit outside or inside the container, depending on its shape.
You can also get creative and decorate your plastic plant-pot saucer lid. Consider painting it with flexible acrylic paint or spray paint designed for plastic surfaces. Sanding the surface lightly before painting can help the paint adhere better.
Remember to consider the purpose of the lid. If you need an airtight seal, ensure the saucer fits snugly and consider adding a seal around the edges with silicone or adhesive. If you're simply looking to keep dust out, a looser fit may suffice.

Using silicone sealant
To make a lid for a plastic container using silicone, you can use silicone putty or silicone sealant. Silicone putty typically comes in two parts, Part A and Part B, which need to be combined in equal amounts and will quickly cure and harden. Before using any silicone putty, it is important to read the material safety data sheet to be aware of any health hazards and safety precautions.
To create a lid, you can use the putty to make a silicone mould that will fit over the top of your container. Alternatively, you can apply the combined silicone mixture directly onto the rim of the container, let it set, and then place the lid on top. This will create a seal around the rim of the container, ensuring an airtight fit.
If you are using silicone sealant, you can apply it directly to the rim of the container or the underside of the lid. One suggestion is to use Vaseline or Isopropyl alcohol mixed with Vaseline on the rim of the container or the lid before applying the silicone. This will help create a stronger seal, but it may be messier and affect the overall appearance. Once the silicone is applied, place the lid on the container and let it cure.
After the silicone has cured, you may need to trim off any excess with a sharp knife or blade to create a clean edge. Now, you have a custom silicone lid for your plastic container. Remember to wash the lid with hot soapy water and dry it off before using it for food storage.

Using a ready-made silicone cover
One of the significant advantages of silicone lids is their versatility. They come in various sizes and shapes, accommodating different-sized containers, including round or rectangular ones. Silicone lids can be stretched to fit mugs, glasses, bowls, and even opened cans. They are also microwave-, oven-, and freezer-safe, making them suitable for various storage purposes.
Another benefit of silicone lids is their durability. Unlike plastic lids that can warp and crack over time, silicone lids are pliable and long-lasting. They are strong enough to withstand the weight of other containers stacked on top, making them ideal for efficient storage and transportation.
Silicone lids are also environmentally conscious choices. They are reusable and washable, reducing the need for disposable plastic wrap or other single-use materials. By investing in silicone lids, you can permanently replace missing or broken lids, reducing waste and keeping your kitchen organised.
When using a ready-made silicone cover, it is essential to measure your containers first and compare them to the available lid sizes. This ensures a proper fit, as silicone lids work best when they adhere well to the container's surface. Additionally, consider handwashing your silicone lids, as dishwashers may cause spots or cloudiness, and their floppy nature may make them challenging to fit in the dishwasher.

Frequently asked questions
You can try using plastic wrap and a rubber band to seal the container. Cut a piece of plastic wrap slightly larger than the opening, tightly push the plastic wrap into the container's mouth, then push the edges down and secure them with a rubber band.
You can use a foam tape, which can be bought at hardware stores. Line the rim of the container with the tape, so it sticks to the container, and repeat the process with the lid. Alternatively, you can use a silicone sealant on the edges of the lid, or Vaseline to create an airtight seal.
You can buy a cork bung or a candle lid from stores like Walmart or Target. Take the container with you to the store and test if the lid fits before buying it.
Plastic plant-pot saucers can be used as container lids. They are inexpensive, come in a variety of sizes and colours, and can be found in hardware stores.
