Punching holes in plastic containers is a task that requires precision and the right tools. While some people opt for using a drill, others worry that this method may cause the plastic to crack. An alternative approach is to use a soldering iron, which can create holes of varying sizes depending on how hot the iron is and how much pressure is applied. For those without access to a soldering iron, a heated metal skewer or a heated needle can also melt holes in plastic containers.

What You'll Learn
Using a soldering iron
To make smaller holes, you can attach a piece of wire to the tip of the soldering iron to create a smaller, secondary tip. The wire should be slightly longer than you think you need, and you can bend it with pliers. Ensure that the wire is securely attached to the soldering tip, as poor contact will result in poor heat conduction. Cut the protruding wire tip down to the shortest length required, as this will provide the most heat.
However, some people have experienced difficulties with this method, as the plastic can stick to the soldering iron, and it can be challenging to control the hole size. It is also worth noting that this method may not work well in colder climates, as the holes may become too big.
Additionally, for hard plastics, it is recommended to use a variable-sized soldering iron tip and work slowly to prevent cracking the plastic.

Drilling holes
To avoid this, it is recommended to use a sharp drill bit and vary the speed, starting slowly and increasing as you go through the plastic. You should also avoid applying pressure and instead let the weight of the drill carry the bit through. This will help to prevent cracking and create a smoother hole.
For hard plastics, some people recommend heating the blunt end of the drill bit, not the drilling tip, to melt the holes through. This can be done by using friction, with the drill bit spinning at a medium to high speed, or by heating the drill bit with a lighter before drilling.
The size of the drill bit will depend on the size of the container and the desired size of the holes. Bits ranging from 1/16 to 5/32 of an inch are commonly used for plastic containers.
It is important to note that drilling may not be the best method for creating holes in all types of plastic. Some plastics, especially hard plastics, may crack more easily when drilled. In these cases, using a soldering iron or other methods may be more effective.

Heating a screwdriver
Firstly, it is important to ensure your work area is well-ventilated to avoid inhaling any fumes from the heated plastic. You can do this by working outdoors or turning on an exhaust fan. Protect your hands with heat-resistant gloves and have a pair of tongs ready to handle the hot screwdriver.
Next, choose a screwdriver with a metal tip. Heat the tip of the screwdriver using a stove, lighter, or another fire source. It is important to ensure the screwdriver is hot enough to melt through the plastic but not so hot that it starts a fire. You may need to experiment with the temperature a few times to find the right balance.
Once the screwdriver is hot enough, gently twist it in a circular motion against the plastic container. Apply light pressure and let the heat of the screwdriver melt through the plastic to create a hole. You can control the size of the hole by adjusting the temperature and pressure applied.
If you are making multiple holes, you may need to reheat the screwdriver periodically as it will cool down between holes. To avoid cracking the plastic, work slowly and do not apply excessive pressure.
Finally, wash the container with soap and water after drilling to remove any plastic residue or toxins from the heating process.
While heating a screwdriver is a viable method, it is worth noting that using a drill with the appropriate drill bits is generally considered the best tool for making holes in plastic containers. Drills can create smoother holes with less risk of cracking the plastic, and they are also more efficient for making multiple holes.

Using a leather punch
Punching holes in plastic containers can be achieved using a leather hole punch. This tool is typically made of steel and comes in various shapes, consisting of a cutting edge and a way to apply force to that edge.
There are several types of leather hole punches, each with a different mechanism for applying force to the cutting edge:
- A revolving hole punch uses the action of pliers to apply force.
- A screw punch uses a downward push with the hand, similar to an awl.
- A drive punch is struck with a mallet.
- A squeeze punch is a set of pliers with a single punch on one side and a flat surface on the other.
When using a leather hole punch, it is important to use a plastic, rubber, rawhide, or wood mallet to strike the punch. A metal hammer will quickly damage the striking end of the punch. Additionally, a thick cutting mat or board should be used to protect the hard surface and the cutting edge of the punch.
The UNCO punch plier is a popular option for punching holes in plastic containers. It is easy to use and offers good value for money, according to customers. To use this tool, simply unlock the handle, rotate the wheel to select the desired hole size, align the plastic container, and squeeze the handles.
Leather hole punches can be purchased online or at craft stores, with prices ranging from $5 to $2500 depending on their intended use.

Heating a needle
To heat a needle, you will need a few simple tools and equipment. Firstly, select an appropriate needle with a size that suits your desired hole size. You can use a large-gauge hypodermic needle, a bobby pin, or any thin metal object that can be heated. A butane lighter or stove can be used to heat the needle. If using a lighter, hold the needle with a pair of pliers, preferably vice-grip pliers that lock into place, to avoid burning your fingers. Heat the needle until it is red-hot or sufficiently hot to melt through the plastic.
Once the needle is hot enough, gently twist it into the plastic to create the hole. You can also try pushing the needle straight into the plastic with light force. If you are drilling multiple holes, work quickly, as the needle will start to cool down once it comes into contact with the plastic. Ensure you work in a well-ventilated area or outdoors to avoid inhaling any fumes released from the heated plastic.
It is important to note that different plastics have different melting temperatures and behaviours when heated. Always work on a solid, non-flammable surface and be cautious of the hot needle to prevent fires or injuries. Additionally, wash the container with soap and water after punching holes to remove any toxins that may have resulted from heating the plastic.

Frequently asked questions
You can use a soldering iron, a drill, a leather punch, a heated metal skewer, a heated needle, a heated screwdriver, a heated baby diaper pin, a heated nail, a heated ice pick, or a dremel.
The size of the drill bit depends on the size of the container and its contents. Drill bit sizes can range from 1/16 to 5/32. For smaller holes, use a 3/32" bit.
Use a sharp-tipped drill bit and let the weight of the drill carry the bit through. Start slowly and increase speed as you go.
Use a soldering iron to make the holes and then use a wood drill bit to enlarge them and remove the blackened plastic.
Use a soldering iron or a heated metal skewer to melt lines instead of holes to create vents. This provides superior ventilation and a cleaner look.
