Airport scanners are designed to identify threats and contraband items, such as firearms, knives, and excessive liquids. These scanners use advanced imaging technologies like X-rays and millimeter wave imaging to detect objects and materials within luggage and on individuals. While plastic itself may not be the target of detection, the contents within plastic containers can be identified, such as pills or liquids. Additionally, airport scanners can detect even the smallest amounts of metal and paper, ensuring a thorough security check for all passengers.

What You'll Learn
Plastic pills bottles are detectable
Plastic pill bottles are detectable by airport scanners. While the plastic material itself may not be detectable, the shape and form of the bottle will be visible on the scan. Airport scanners are designed to detect unusual shapes and items that look different from the norm. Plastic pill bottles are typically made from polypropylene, also known as "#5 plastic", which is a lightweight yet sturdy material. It is also used for yoghurt containers and many reusable food-safe containers.
Pill bottles are designed to be airtight and to keep their contents dry. This makes them useful for storing items other than pills, such as liquids, gels, or even electronic devices. They are also useful for keeping items away from children. Due to their small size, they are convenient for storing items in discreet places, such as in a car or handbag.
When travelling with liquids in plastic pill bottles, it is important to adhere to airport security regulations. Liquids carried in hand luggage must be in containers holding no more than 3.4 ounces (100ml) and are subject to X-ray scans. Plastic pill bottles are generally permitted for carrying small amounts of liquids through airport security.
However, it is important to note that recycling plastic pill bottles can be challenging. Many local recycling programs do not accept #5 plastics due to limitations in waste management infrastructure. Even when recycling centres accept #5 plastic, their sorting machines often cannot handle such small items, leading to the bottles ending up in landfills or incinerators. As an alternative, some companies are developing biodegradable and recyclable paperboard-based medication containers.

Plastic is safe to pass through
While plastic is safe to pass through airport scanners, the scanners can detect the presence of plastic items. Airport scanners can identify the material of an object passing through them. They can detect the smallest amount of metal, paper, and even pills, whether in plastic, non-metallic, or metallic bottles.
The scanners are designed to look for threats and will flag items that look different from the norm. They can also detect money, especially if it is arranged in bundles. If you have a medical device or something else that you think might set off the alarms, it is best to inform the Transportation Security Officer (TSO) before entering the scanner.
In addition to AIT scanners, metal detectors, facial scanners, and body scanners are also used at airports. These machines are in place for your safety, but they may make some people feel uncomfortable, especially the body scanners. It is important to remember that airport scanners do not show your naked body on the screen.

Advanced Imaging Technology (AIT)
Unfortunately, I could not find sufficient information to write 4-6 paragraphs on Advanced Imaging Technology (AIT) in relation to plastic showing up on airport scanners. However, here is some information that might be useful.
Airport scanners can detect the smallest amounts of metal, paper, and even pills contained in plastic, non-metallic, or metallic bottles. They can also detect money, especially if it is arranged in bundles. These scanners use advanced imaging technology (AIT) to identify objects that look different from the norm.

X-ray vs. millimeter wave imaging
Plastic can indeed be detected by airport scanners. Airport scanners use either X-ray or millimetre wave technology to screen passengers and their luggage. Both technologies have their advantages and disadvantages in terms of safety, privacy, and detection capabilities.
X-ray scanners use ionizing radiation, which is known to be hazardous to human health. Due to this, the use of X-ray equipment is highly regulated, and companies may have concerns about potential health hazards for workers exposed to high levels of X-rays. X-ray scanners produce detailed images of the surface of the skin under clothing, prosthetics, and other medical equipment, which has raised privacy concerns. Backscatter X-ray scanners use a parallel stream of low-energy X-rays, which penetrate clothing and bounce off the skin and any concealed items, forming an image.
On the other hand, millimetre wave scanners use radio waves that are human-safe and can see through non-metallic packaging materials such as plastic. These scanners produce a generic outline of a person, with specific areas of suspicion highlighted, addressing privacy concerns. Active millimetre wave scanners direct millimetre wave energy at the subject and interpret the reflected energy, while passive systems create images using only ambient radiation and radiation emitted from the human body or objects. The first millimetre-wave full-body scanner was developed at the Pacific Northwest National Laboratory (PNNL) in Richland, Washington, and patented in the 1990s.
In terms of detection capabilities, X-ray scanners can detect metal and paper, and they can also detect pills, even if they are contained in plastic or non-metallic bottles. Additionally, X-ray scanners can detect money, especially if it is arranged in bundles. While millimetre wave scanners have been questioned for their efficacy in detecting threatening objects, they are capable of detecting liquids, gels, plastics, powders, metals, ceramics, explosives, drugs, and money, according to studies.
Overall, both X-ray and millimetre wave scanners have their strengths and weaknesses, and the choice between the two technologies depends on various factors, including safety, privacy, and detection needs.

Detecting threats and contraband
AIT scanners, also known as millimetre wave scanners, use a special type of microwave to create an image of the passenger's body and any items they may be carrying. These scanners do not use X-rays, and the radiation emitted is significantly lower than that of a cellphone, making them safe for passengers.
X-ray machines, on the other hand, are used to inspect carry-on and checked baggage. These machines can identify the materials of objects passing through them and detect threats such as firearms, knives, and explosives. They can also identify contraband items such as excessive liquids and gels. Additionally, X-ray scanners can detect money, even when bundled, and small amounts of metal, regardless of whether they are in metallic or non-metallic containers.
It is important for passengers to cooperate with security procedures by removing items from their pockets and declaring any medical devices that may set off the scanners' sensors. While older versions of body scanners raised privacy concerns by creating naked images of passengers, newer AIT scanners do not produce such images, ensuring the privacy of those being screened.

Frequently asked questions
Plastic will show up on airport scanners. Scanners can detect the smallest amounts of metal, paper, and plastic.
Airports use Advanced Imaging Technology (AIT) for full-body scans. The newer AIT scanners use millimeter-wave imaging, a special type of microwave, not an X-ray.
Airport scanners are looking for threats and dangerous materials. They can detect metal objects, such as firearms and knives.
