What You'll Learn
Plastic bottles
Airport scanners use X-ray technology to inspect the contents of luggage. These X-rays pass through luggage and are absorbed at different rates by various materials inside. The scanner then generates an image that security personnel can analyze. The image produced is colour-coded based on the density and atomic number of the materials, allowing for differentiation between organic, inorganic, and metallic substances.
While airport scanners are highly effective, they do have limitations. For example, they can be triggered by everyday items like belt buckles, jewellery, and coins, leading to false positives and potential delays in the screening process. Additionally, X-ray scanners cannot see through dense metal objects, and metal objects may obscure the view of the contents inside a bottle, necessitating additional inspection.

Plastic explosives
The first plastic explosive was gelignite, invented by Alfred Nobel in 1875. Before World War I, British explosives chemist Oswald Silberrad patented a series of plastic explosives called "Nitrols", composed of nitrated aromatics, collodion, and oxidising inorganic salts. During World War II, the British Special Operations Executive (SOE) extensively used Nobel's Explosive No. 808, also known as Nobel 808 or simply Explosive 808, for sabotage missions. This explosive had the appearance and texture of green plasticine and a distinctive almond smell.
After World War II, new RDX-based explosives were developed, including Compositions C, C2, and C3, which incorporate plasticizers to decrease sensitivity and make the composition plastic. Composition C2 had a wider plastic temperature range than its predecessor, from −30 to 52 °C (−22 to 126 °F). Composition C3 was replaced by C4 due to its brittleness in cold weather. C-4 is similar in structure to Semtex and is known to produce a "buzz" in addition to the explosion.
Airport scanners utilise advanced X-ray technology to identify potential threats to aviation security. They can detect metallic objects like knives and guns, as well as non-metallic items made from plastics, ceramics, and glass, by differentiating between materials based on how they absorb or reflect X-rays. This means that plastic explosives can be identified through their density and atomic number, which affect how much they absorb or scatter X-rays. These scanners provide detailed images, allowing security officers to identify suspicious items and ensure aviation safety.

Plastic weapons
Airport baggage scanners are designed to ensure aviation safety by meticulously inspecting the contents of travellers' luggage. They can identify metallic objects, such as guns and knives, through the interaction of X-rays with metal, producing distinct images on security monitors. However, their capabilities extend beyond metal detection.
These scanners can also detect non-metallic objects, including those made of plastic, ceramics, and glass, by assessing their density and atomic number, which influences X-ray absorption and scattering. This capability allows the detection of plastic explosives, contraband, and other potential threats. Organic materials, such as food, liquids, drugs, and explosives, can be differentiated from dense objects like metals or plastics, aiding in the identification of suspicious items.
While airport scanners can provide detailed images of luggage contents, they may not always identify the exact nature of objects. In such cases, security personnel may need to manually inspect the luggage. Plastic weapons, such as knives made from materials like plastic, Grivory composite, fiberglass, carbon fibre, or polymers, are designed to evade detection by metal scanners. These non-metallic knives are often lightweight, durable, and concealable, making them attractive for self-defence or covert purposes. However, airport scanners can detect non-metallic objects, including plastic weapons, by assessing their density and interaction with X-rays.
The ability to detect plastic weapons is crucial for aviation security. While plastic knives may not trigger metal detectors, they can still be identified through advanced X-ray technology and manual inspections. It is important to understand that attempting to bring any weapon, including plastic knives, onto an aircraft is illegal and poses a significant safety risk. Passengers should adhere to airport security regulations and refrain from carrying any prohibited items to ensure a safe travel experience for all.

Plastic vs. metal
Airport baggage scanners are designed to ensure aviation safety by meticulously screening the contents of travellers' luggage. These scanners employ advanced X-ray technology to differentiate between various materials, including plastics and metals.
Plastics and Ceramics:
Plastic items, such as containers or explosive components, can be challenging for older security systems to detect. However, modern X-ray scanners can identify plastic objects by assessing their density, shape, and other visual cues. Plastic bottles, for example, may be transparent to X-rays, allowing scanners to see through them and identify their contents based on density and absorption characteristics.
Metallic Objects:
Metal objects, such as knives, guns, and other potential weapons, are easily detected by airport scanners due to the distinct interaction of X-rays with metal. This interaction creates a clear and distinct image on the security monitor, enabling the identification of metallic items within luggage. Metal bottles or containers, however, can be more challenging for X-ray scanners to penetrate, sometimes requiring additional inspection to identify their contents.
Differentiating Factors:
The key differentiating factor between plastic and metal detection lies in their respective interactions with X-rays. Plastic items are identified through their density, shape, and how much they absorb or scatter X-rays. In contrast, metal objects are detected due to the distinct images they create on the security monitor as a result of X-ray interaction.
Security Measures:
To enhance security, millimetre-wave scanners are employed to detect both metallic and non-metallic items, including weapons, explosives, and drugs. Additionally, 3D imaging technology allows security personnel to view luggage from multiple angles, helping to identify hidden compartments or cleverly concealed items. These advancements ensure that potential threats, whether made of plastic or metal, are detected to maintain aviation security.

Plastic drugs packaging
Plastic is a common material used for pharmaceutical packaging. Plastic bottles are the packaging choice for many medicines, supplements, and lifestyle products. Blister packs, which are pre-formed plastic/paper/foil packaging, are also commonly used for solid unit doses of pharmaceuticals (capsules, suppositories, tablets, etc.). Plastic is also used for pharmaceutical packaging due to its sustainability and the fact that it can maintain the moisture content of active ingredients, preventing deterioration and ensuring the therapeutic efficacy of the drug over time.
When it comes to airport scanners, they utilise advanced X-ray technology to see through dense materials and identify items based on their density and atomic number. This means that airport scanners can detect both metallic and non-metallic objects, including items made of plastic. However, it's important to note that airport scanners may not always be able to establish the exact composition of the objects they detect.
In the context of drug packaging, airport scanners can provide visual clues of drugs hidden in baggage or under clothing. Organic materials, including drugs, are marked with a specific colour on the scanner, indicating a need for further inspection. Additionally, passengers suspected of swallowing drugs may undergo a full-body X-ray scan, which can detect packages inside the person's stomach, regardless of whether the drugs are contained in plastic or metallic bottles.
To address the challenge of drug detection, advancements in plastic drug packaging have considered the issue of counterfeit drugs. Custom package seals, authentication labels, holograms, and security printing are now being utilised to verify the authenticity of the enclosed drugs. These measures help ensure that patients receive legitimate and safe medications while also deterring the distribution of counterfeit drugs.
