What You'll Learn
Choosing the right glue
Firstly, you need to identify the type of plastic your container is made of. Hard plastics like buckets or crates are often made of polyethylene or polypropylene, which are challenging to glue and require specific adhesives marked for these plastics. On the other hand, clear, brittle plastics like imitation glass or CD cases are typically polystyrene, which can be effectively glued using a poly cement like Loctite Plastic Bonder.
If your plastic container is a common household item, you can determine the type of plastic by checking the number or symbol on the item. For example, plastics marked with a 6 or "PS" are polystyrenes, which are used for disposable cutlery, plastic bowls, and fashion bags. In contrast, LDPE plastics, often used for squeezable bottles and plastic bags, have very low surface energy, making it challenging for most household glues to bond effectively.
Once you've identified the plastic type, you can select the appropriate adhesive. Here are some common types of glue and their uses:
- Plastic Cement: This adhesive is specifically formulated for plastics and works by slightly melting the surfaces, which then fuse as the adhesive dries.
- Cyanoacrylate Adhesives (Super Glues): Super glues are versatile and suitable for various household repairs, but they may damage certain plastics. They are ideal for smaller repairs that require a quick set time.
- Epoxy Adhesives: Epoxy is a two-component adhesive that forms a durable, long-lasting, and strong bond. It is often used when bonding strength is a priority.
- Acrylic Adhesives: Acrylic adhesives cure to form a clear, transparent join, making them ideal for hidden repairs.
- Hot-Melt Adhesives: Applied with a glue gun, these adhesives create a bond as they cool and are excellent for situations requiring speed and flexibility. However, they may not work well with all plastic types.
When gluing a bow to a plastic container, it is crucial to follow the manufacturer's instructions for the specific adhesive you choose. Additionally, preparing the plastic surface by cleaning and sanding it can significantly improve adhesion.

Preparing the plastic surface
Cleaning the Surface
Start by cleaning the plastic surface with soap and water or a specialised plastic cleaner. You can also use isopropyl alcohol to clean the surface, which is especially useful for removing any oily or greasy residues. If there are any contaminants or debris on the surface, use a volatile solvent such as toluene, acetone, or methyl ethyl ketone to degrease the surface. Ensure that you follow health and safety regulations when working with solvents.
Drying the Surface
After cleaning, it is important to dry the plastic surface thoroughly. Use a clean cloth or paper towel to remove any remaining moisture. Alternatively, you can allow the surface to air-dry completely before proceeding to the next step.
Roughening the Surface
To create a better surface for the glue to bond to, you can roughen the plastic surface. Use sandpaper with a grit of 120 to 200, or steel wool/emery cloth to briefly rub the surface, creating a coarse texture. This step can be skipped if your plastic surface already has a rough texture.
Avoiding Touching the Surface
As oils from your skin can interfere with the glue's adhesion, avoid touching the cleaned and prepared plastic surface with your bare hands. Use gloves or handle the surface with clean cloth or tissue when necessary.
Priming the Surface
Some sources suggest using a plastic primer or an activator product to further enhance the adhesion of the glue. These products can help roughen the surface and improve the bond strength.
Choosing the Right Glue
Finally, select the most suitable glue for your specific plastic type. Flexible plastics often require special adhesives, and some glues are designed for specific types of plastic, such as polystyrene. Consider the strength and flexibility required for your project and always read the instructions on the glue packaging.

Attaching the bow
Before gluing the bow to your plastic container, it is important to prepare the surface of the container. Clean the plastic surface with soap and water, or use a specialised plastic cleaner. You can also soak the plastic in isopropyl alcohol to ensure it is thoroughly cleaned. Dry the container completely before proceeding to the next step.
To create a rough surface that will help the glue bond effectively, sand the area of the container where you plan to attach the bow. Use fine-grit sandpaper and work gently until you achieve a slightly rough texture. Avoid touching the sanded area with your bare hands to minimise oil residue.
Now you are ready to apply the glue. For precise application, especially if you are gluing a small or detailed bow, use a small paintbrush or the tip of a needle. Choose a glue that is suitable for the type of plastic your container is made of. Flexible plastics, for example, require a specific type of adhesive, such as Loctite Vinyl, Fabric & Plastic Flexible Adhesive. This type of glue is also ideal if your container will be exposed to sunlight, as it won't break down or yellow over time.
Apply the glue to the sanded area of the container, following the manufacturer's instructions for the specific product you are using. Attach the bow firmly, holding it in place for several seconds to ensure a strong bond. If you are using a hot glue gun, be careful not to burn yourself and take extra care with this step.
Finally, allow the glue to dry completely. Depending on the type of glue you use, you may need to let it dry overnight to ensure a secure bond. Once the glue is dry, your bow should be firmly attached to your plastic container.

Drying and curing the glue
Before applying any glue, it is important to select the right adhesive. For gluing a bow to a plastic container, choose a glue specifically designed for bonding plastic materials. Look for adhesives formulated for flexible plastics if the container is made of flexible plastic. Ensure that the glue is suitable for indoor use and always follow the manufacturer's instructions. Some glues may be sensitive to heat, so be cautious when applying additional heat.
Once you have selected the appropriate glue, prepare the plastic surface by cleaning it thoroughly with soap and water, a specialised plastic cleaner, or by soaking it in isopropyl alcohol. This step ensures that any dirt, oil, or residue is removed, creating a better bonding surface. After cleaning, dry the plastic surface completely before gluing.
When applying the glue, use the smallest amount necessary to create a secure bond. Too much glue can increase drying time and weaken the bond. If possible, work in a warm environment with low humidity, as glue cures faster at higher temperatures and lower moisture levels. Additionally, choose a well-ventilated area, as many types of glue cure with air exposure.
To speed up the drying process, you can use a hairdryer, especially for craft glue or glue-like products. Hold the hairdryer approximately 12 inches (30 cm) away from the surface for 2-3 minutes. Be cautious not to use the hairdryer for extended periods to avoid potential damage from excess heat. Alternatively, you can use a fan to increase airflow and ventilation, pointing it directly at the glued area.
If you are using super glue, consider applying an accelerator product. Accelerators are designed to drastically reduce the curing time of super glue, causing it to turn solid in just a few minutes. Additionally, if you are working with hot glue, you can use compressed air to dry it instantly. Turn the can of compressed air upside down and spray it over the hot glue to chill and solidify it in seconds. However, exercise caution when using compressed air, as it can be dangerous if it comes into contact with your skin.
By following these instructions and allowing adequate curing time, you can ensure that the glue dries effectively, resulting in a strong and long-lasting bond between the bow and the plastic container.

Decorating the container
Decorating plastic containers can be a fun and creative process, allowing you to turn plain containers into stylish pieces of art or elegant keepsakes. Here are some ways you can decorate a plastic container:
Sanding and Painting
Before painting a plastic container, it is important to prepare the surface. Start by cleaning the container with soap and water, or use a specialised plastic cleaner. Then, sand the surface with fine-grit sandpaper to create a rough texture that will help the paint adhere better. You can also use steel wool or emery cloth for this step, but be gentle and brief to avoid damaging the plastic. Once the surface is prepared, you can apply paint using spray paint or a foam brush. Choose a paint that is suitable for plastic and weather-resistant if the container will be outdoors. Consider using a base coat and adding additional coats in your desired colours, allowing each layer to dry in between. You can also create a wash by mixing half paint and half water for a subtle effect.
Clay Impressions
Another creative way to decorate a plastic container is by using clay impressions. Start by dusting your molds with cornstarch to ensure the clay releases easily. Then, fill your molds with air-dry clay, slightly overfilling them. Use a ruler to remove any excess clay, leaving you with neat and refined impressions. Experiment with different designs and arrangements until you find something you love. Once your clay designs are ready, attach them to the container using a strong adhesive like a glue gun or mod podge glue. Let the glue dry overnight to ensure the clay impressions are securely attached.
Ribbons and Stickers
Ribbons are an easy and effective way to decorate plastic containers, especially those with holes. You can weave a ribbon through the holes, leaving enough at the end to tie a bow. You can use one long ribbon or multiple shorter ones, depending on your preference. Colourful ribbons can add a festive touch to the container, making them perfect for holidays or occasions like baby showers. For a more permanent solution, attach ribbons using mod podge, hot glue, or tape. You can also combine ribbons with stickers, stencils, spray paint, duct tape, scrapbooking paper, and buttons to create unique and stylish designs.
Sealing Your Creation
Once you have finished decorating your container, you may want to consider sealing it to protect your design and make cleaning easier. You can use a clear water-based spray acrylic or an acrylic spray sealant to add a matte or glossy finish. This will not only enhance the appearance of your container but also ensure your artwork lasts for a long time.
