Using adhesive: industrial-strength velcro glue, foam tape, or contact cement
When using adhesive to stick Velcro to plastic, there are a few options to consider: industrial-strength Velcro glue, foam tape, contact cement, epoxy, or silicone-based adhesives. Each option has its own advantages and considerations.
Industrial-strength Velcro glue is specifically designed for bonding Velcro to various surfaces, including plastic. This type of glue is known for its strong adhesive properties and can be found at craft stores or online. When using this glue, it is important to follow the manufacturer's instructions for the best results.
Foam tape is another option, especially when dealing with textured plastic surfaces. The thickness of the foam tape can help to create a stronger bond by filling in the gaps and uneven surfaces. This option is readily available at most craft or hardware stores and can provide a quick and easy solution.
Contact cement is a permanent adhesive that can be used to attach Velcro to plastic. To use contact cement, apply it to both surfaces, wait until it is dry, and then press the two sides together to create a strong, permanent bond. This option may require more preparation and drying time but can provide a long-lasting solution.
Epoxy is another adhesive that can be used, but it is important to note that it can be brittle in thin layers. However, epoxy fills gaps well and can be a suitable option for certain applications. Silicone-based adhesives are also recommended for bonding plastic to plastic. These adhesives are known for their flexibility and ability to withstand harsh conditions.
Additionally, it is worth mentioning that preparing the plastic surface before adhesion can significantly improve the bond strength. Cleaning the plastic surface with denatured alcohol or acetone can enhance the adhesive properties and ensure a stronger hold.

Using heat: blow dryer then roller
Using heat to stick Velcro to plastic can be done through a blow dryer and then a roller. First, ensure the plastic surface is clean. Then, use a blow dryer on the plastic surface to heat it up. Once the plastic is heated, use a roller to apply pressure to the Velcro, pressing it onto the plastic.
The blow dryer can be used to heat up the plastic surface, softening it and making it more malleable. This allows the Velcro to adhere more easily and creates a stronger bond. It is important to be cautious when using a blow dryer, as too much heat can damage the plastic or the Velcro. It is also important to ensure that the blow dryer is set to a low airflow to avoid disturbing the placement of the Velcro.
Additionally, the roller can be used to apply pressure to the Velcro, helping it to adhere to the plastic surface. The roller can be rolled over the Velcro, applying even pressure and creating a stronger bond. This method can be especially useful if the Velcro is not self-adhesive or if the adhesive backing has lost its stickiness.
When using this method, it is important to work in small sections, especially if the plastic surface is large. This ensures that the heat from the blow dryer is concentrated on a specific area, creating a stronger bond. It is also important to work quickly, as the plastic will cool down and harden, making it more difficult for the Velcro to adhere.
Using a combination of heat and pressure through a blow dryer and roller can be an effective way to stick Velcro to plastic. This method can create a stronger bond and ensure that the Velcro stays in place. However, it is important to be cautious when using heat to avoid damaging the materials.

Using rivets: pop-rivet with washers
Using rivets to stick velcro to plastic can be a good option, but it's important to note that rivets are not ideal for plastic as they can loosen over time and are difficult to remove. If you decide to use rivets, here's a step-by-step guide on how to use pop-rivets with washers:
First, decide on the placement of the velcro and mark the spots where you will be drilling the holes for the rivets. If the plastic is thin and flexible, you can simply punch holes through it using a leather punch. However, if the plastic is rigid, you will need to drill holes to accommodate the rivets. Make sure the holes are accurately drilled and slightly larger than the rivet shaft to distribute the stress.
Next, insert the rivet into the hole, making sure the washer is placed under the rivet head. The washer will help distribute the load and protect the plastic from the bearing surface of the rivet hole. You can use one or two washers, depending on the load and your personal preference.
Once the rivet and washer are in place, use a rivet gun or hand riveter to expand and deform the tail of the rivet, creating a tight hold. Make sure to follow the instructions provided with your rivet tool for the best results.
Depending on the length of the velcro strip, you may want to add additional rivets at each end and in the middle for extra security. If the velcro becomes slack over time, you can use glue or the original self-adhesive backing to help the materials lie together, with the rivets taking the load.
While this method can be effective, keep in mind that rivets are not ideal for plastic due to the potential for loosening over time and the difficulty of removal. If the application involves frequent movement or heavy loads, consider using bolts and nuts instead, as they can be tightened if needed.

Using alcohol: clean the surface with denatured alcohol or acetone
When sticking Velcro to plastic, it is important to prepare the surface of the plastic first. One way to do this is by cleaning the surface with denatured alcohol or acetone. Denatured alcohol is a type of alcohol that has been treated with a denaturing agent to make it unfit for human consumption. It is often used as a solvent or cleaning agent.
Before gluing the Velcro to the plastic, it is recommended to clean the plastic surface with denatured alcohol or acetone to ensure that the glue adheres properly. This step will help to remove any dirt, grease, or oils that may be present on the plastic surface, which can interfere with the adhesion of the glue.
To use this method, simply apply a small amount of denatured alcohol or acetone to a clean cloth and wipe down the plastic surface. It is important to ensure that the plastic is completely dry before attempting to glue the Velcro in place. This method is particularly useful if you are working with a type of plastic that cannot be punctured, such as a map case or a laminated poster.
While acetone is a powerful solvent that can effectively clean surfaces, it should be used with caution as it can be toxic and may damage certain types of plastics. Denatured alcohol, on the other hand, is generally considered safer to use on plastics and will not damage the material. It is always a good idea to test any cleaning solution on a small, inconspicuous area of the plastic first to ensure that it does not cause any adverse reactions.
In addition to cleaning the plastic surface, it is also important to prepare the Velcro itself for adhesion. This can be done by roughing up the surface of the Velcro with sandpaper to create a slightly uneven surface for the glue to grip onto. Once both the plastic and the Velcro are prepared, you can apply a suitable adhesive, such as a silicone-based adhesive or a two-part cyanoacrylate system, to create a strong and durable bond.
