How to reinforce plastic organizer drawers?

Please explain more fully or send picture showing problem.

In what way do you mean reinforce?

Maybe you should just replace the plastic. Build your own drawer organizers from craft foam board and duct tape. Measure the drawer on the inside from edge to edge front to back (ftb), then from side to side (sts), finally measure the depth of the drawer.

Buy some 1/4 inch craft foam board. It's available at any place that sells arts or craft materials, including your grocery store. Decide how many compartment you want. Measure out 1 or 2 sections of foam board in the length of the sts and 1/2 to 1 inch shorter than the drawer depth. Measure out 3 or 4 sections in the shorter front to back length and matching the depth of the first piece(s). Before you cut make sure you have a cutting board or other suitable surface below. Cut them out using a craft knife or a box cutter with a sharp blade. Cut 1/4 inch notches along the sts piece(s) on the top only. Cut matching notches on the ftb pieces on the bottom only. Slip the notches from one piece into the notches of another, making a grid. Test the construction by slipping it into the drawer. Here is how they should look when you put them together, though they did not need the sts piece at the back. The one shown is cardboard. Foam board will look much nicer. https://i.pinimg.com/736x/de/d1/fa/ded1fa6a845a5416f1f648c9dfa52fe9--organizing-socks-socks-organization.jpg

Duct tape comes in a lot of colors and patterns, including white. You can use whatever color you like, but the duct tape is primarily to cover any visible cut edges. Cut a piece of duct tape the ftb width of the foam board pieces. Lay it on the top edge of a piece, centering it. Cut the tape on either side of an intersection and press the sides down. Do this for each of the ftb pieces. Try to keep the construction squared. Finally, cut duct tape for the sts piece(s) and place it over the center top edge, clipping at intersections and folding it down as before. You can stiffen the piece by applying tape up and down to each side of each intersection, but it's not necessary; the drawer holds everything in place. Slip the construction into the drawer and fill the compartments with your stuff.

There are a few ways you can reinforce plastic organizer drawers to make them stronger:

1. Use plastic or metal brackets to reinforce the corners of the drawers. These can be attached to the inside corners of the drawers using screws or adhesive.
2. Add reinforcing strips to the sides of the drawers. These can be made of wood, metal, or plastic and can be attached using screws or adhesive.
3. Use reinforcing plates to strengthen the bottom of the drawers. These can be made of metal or plastic and can be attached using screws or adhesive.
4. Use a reinforcing adhesive, such as epoxy, to add extra strength to the plastic. Follow the instructions on the product and be sure to use it in a well-ventilated area.

Remember to use caution when reinforcing plastic organizer drawers, as overloading them can still cause them to break or become damaged.

Use a blow dryers to heat up the plastic slightly (this is only to get a snuggly fitting piece of wood in the bottom of the drawer. The added strength of the wood will help make the entire unit more strudy.

Considering how light these are look for something like luan which is just a very thin but still strudy board which is easily cut to size.
