Choosing the right glue for the right plastic
When it comes to choosing the right glue for plastic boning, it's important to consider the type of plastic you're working with. Different types of plastics require different types of adhesives, and using the wrong glue can result in weak bonds or damage to the plastic. Here are some factors to consider when selecting the appropriate glue for your plastic boning:
First, identify the type of plastic your boning is made of. This information may be indicated by a recycling symbol or code on the packaging. Common types of plastic include High-Density Polyethylene (HDPE), marked with Recycling Symbol 1, which is often used for durable items like detergent bottles and buckets. Flexible plastics, such as those used for shoes or toys, require adhesives specifically formulated for flexibility, like Loctite Vinyl, Fabric & Plastic Flexible Adhesive.
Another type of plastic is polystyrene, marked with Recycling Symbol 6 or "PS". This plastic is often used for disposable items like cutlery, bowls, and fashion bags. A suitable glue for polystyrene is poly cement, such as Loctite Plastic Bonder. Epoxies and spray adhesives also work well with polystyrene.
For harder plastics, like those used for buckets, crates, or containers, ordinary white glues, wood glues, or common adhesives may not form strong or permanent bonds. Instead, consider a two-part cyanoacrylate adhesive like the Loctite Plastics Bonding System, which creates a powerful bond with just one drop.
If you're working with PVC, which is commonly used in plumbing, you can find a two-part primer and PVC solvent cement in most hardware or home improvement stores.
Additionally, some plastics fall under the "'Others'" category, marked with Recycling Symbol 7. These include polycarbonate and acrylic. For polycarbonate, an epoxy adhesive will work best. For bonding materials like polycarbonate, acrylic, Nylon, Mylar, and more, Loctite Plastic Bonder is recommended for its strong and impact-resistant bond.
When in doubt, it's always a good idea to do some research or consult with experts to ensure you choose the right adhesive for your specific plastic boning application.

Preparing the substrate and plastic surface
Cleaning and Degreasing:
Start by thoroughly cleaning the substrate and plastic surface to remove any contaminants, such as dirt, oil, or debris. Use volatile solvents like acetone or isopropyl alcohol for degreasing, ensuring compliance with environmental, health, and safety regulations. Immerse the substrate in a solvent bath, followed by a rinse in a separate tank.
Abrasion and Roughening:
After cleaning, you may need to abrade the surfaces to create a rough texture that enhances adhesion. This can be done with sandpaper or other abrasion techniques suitable for the specific plastic being used. Be cautious and consider the feasibility of abrasion for the particular material.
Drying and Priming:
Ensure that the surfaces are completely dry after cleaning and abrasion. You may use a chemical pretreatment process, but this is often time-consuming and challenging. Instead, consider priming the surface as a cheap and easy alternative to enhance adhesion. However, test the products beforehand to ensure compatibility between the primer, adhesive, and substrate.
Surface Treatments:
There are various surface treatment methods to increase surface reactivity and improve adhesion. Flame treatment involves exposing the surface to a gas flame for a few seconds, but be cautious as it may deform certain plastics. Corona treatment is another option, where the surface is exposed to an electric discharge, similar to an electric shock, which oxidizes and increases surface energy.
Compatibility and Adhesive Selection:
Before attaching the plastic boning, ensure that the adhesive is compatible with the plastic and substrate. Avoid fast-cure adhesives as they may cause cracking. Additionally, consider the placement of the boning in relation to the seams and zipper to determine the best adhesive approach.
By following these steps, you can effectively prepare the substrate and plastic surface, ensuring a strong and durable bond when attaching plastic boning.

Applying glue to both surfaces
When attaching plastic boning, it is important to apply glue to both surfaces securely. Firstly, ensure you have created a casing or channel for the boning to slide into. This can be done by stitching along the seams or using strips of fabric. The casing should be made from firm, tightly woven fabric to provide structure and support. Stitch the casing to the fabric, creating a channel wide enough for the boning to fit into but narrow enough to prevent twisting.
Before gluing, determine the placement of the boning. The most common places to add boning are along the seams and at the centre back of a garment. Mark the placement of the boning with a fabric marker or tailor's chalk. Cut the boning to the appropriate length, ensuring it fits snugly within the channel. If using flat boning, use a sharp tool to smoothen any sharp corners, creating a rounded edge.
Apply a thin layer of glue to both the inside of the casing and the surface of the boning. Ensure the glue is suitable for use on plastic and fabric. Spread the glue evenly, covering all areas that will be in contact with each other. Allow the glue to become tacky for a few minutes, following the manufacturer's instructions for drying time.
Carefully insert the glued boning into the casing, sliding it into the channel. Ensure the boning is positioned correctly and securely in place. You may need to use clips or pins to hold the boning in place while the glue dries completely. Check that the boning does not twist or move out of place during this process.
Finally, stitch the casing closed at both ends to secure the boning. Sew across the top and bottom of the casing, backstitching for extra security. This will prevent the boning from sliding out. Trim off any excess fabric or casing that extends beyond the edges of the garment.

Pressing surfaces together
Pressing the surfaces together is a crucial step in creating a neat and secure boning channel. Here is a detailed guide on this process:
Firstly, determine the placement of your boning channels. Common areas for adding boning are along the seams, especially the centre back, and you can add more depending on the desired structure. If you are using a pattern, follow its instructions for boning placement. For instance, consider placing the boning on princess seams and side seams for light support.
Next, prepare your casing. If your boning comes with a pre-made casing, ensure it is the correct length for your seams. If not, create your own casing by cutting fabric strips on the bias, which provides some stretch. Cut the strips slightly wider than your seam allowances to ensure the boning can slide in easily. Pin the casing over each seam, and sew it in place.
When pressing the surfaces together, there are two common methods. One method is to press the seams open and centre the casing over the seam, sewing it to the inside of the lining. This approach ensures the stitching is hidden inside the finished garment. The other method is to press the seams to the side and sew the casing just off-centre from the seam. This second method is preferred by some as it creates a stronger seam with less chance of breakage, and the boning being slightly off-centre is usually unnoticeable.
When sewing the casing in place, stitch along both edges of the casing, creating a channel wide enough for the boning to slide through but narrow enough to prevent twisting. Sew across one end of the casing before inserting the boning to secure it in place.
Finally, insert the boning into the channel. If you are using flat boning, you may want to label each piece with its corresponding casing to ensure correct placement. Sand down any sharp corners of the boning with a metal file and cover any exposed metal ends with tape or tool dip to create a smooth finish. Slide the boning into the channel, ensuring it doesn't catch on the seams. Once the boning is in place, hand- or machine-stitch the open end of the casing to secure it.

Using clamps, tape, or rubber bands to hold the pieces together
Clamps, tape, and rubber bands can be used in conjunction with sewing to hold pieces of fabric together when attaching plastic boning in a channel. Here are some ways to use these tools effectively:
Using Clamps
If you need to hold multiple layers of fabric together while sewing boning channels, clamps can be a helpful tool. Spring clamps are a good option, and you can modify them by wrapping rubber bands around the jaws to create instant edge clamps that grip the fabric more securely. This setup is especially useful if you need to glue fabric together before sewing, as the clamps will hold the pieces in place until the glue dries.
Tape Selection
When using tape to hold fabric pieces together, it is essential to choose a type of tape specifically designed for fabric. Avoid tapes like Gorilla Tape or mounting tape, as these may damage the fabric. Instead, opt for fabric tape, which provides a strong hold without ruining the material. Double-sided fabric tape is a good option as it is invisible and provides a secure hold. Single-sided fabric tape is also available for hemming and can be a good temporary solution before sewing.
Tape Application
Before taping your fabric pieces together, ensure they are lined up accurately. Apply the fabric tape along the seams where the boning channels will be sewn, pressing it firmly in place. If using double-sided tape, apply it to both sides of the fabric pieces that need to be joined, ensuring accurate alignment.
Rubber Bands
Rubber bands can be used in a similar way to clamps to hold fabric pieces together. Stretch the rubber bands around the fabric layers, ensuring they are taut and secure. This method is especially useful if you need to hold multiple layers of fabric together and require flexibility in your setup.
When using clamps, tape, or rubber bands to hold fabric pieces together for boning channels, always ensure that your tools do not interfere with your sewing process. These methods can help you achieve accurate results by keeping your fabric layers in place until they are sewn together.
