What materials do manufacturers typically use to make pill boxes? Most pill boxes on the market are made of plastic or aluminum alloy. Pill boxes made of titanium alloy, bamboo, or wood are relatively rare.

Alright, let’s get right to the point. What materials are available? This article will provide a detailed analysis of the pros and cons of each material to help you better understand pill boxes.

Plastic pillboxes - PP, PS, ABS materials

Currently, plastic is the most commonly used material for pill boxes. If you visit Amazon’s pill box page, you’ll find that most of them are made of plastic. PP, PS, and ABS are the primary raw materials used in plastic pill boxes.

1. PP material:

PP (Polypropylene) is a thermoplastic polyolefin polymerized from propylene monomers. It is the most commonly used material for plastic pill boxes.

Advantages of using PP material to manufacture pill box

Safe and non-toxic

BPA-free, it can directly contact medicines without reacting with them . It ensures stable drug efficacy, making it an ideal material for pill box.

Strong chemical resistance

High-quality PP material is resistant to most acids, alkalis, and salts, with a water absorption rate of less than 0.01%. As a result, it is ideal for manufacturing pill boxes with exceptional moisture-proof properties, effectively protecting medications from moisture and mold.

Some pill boxes also have silicone sealing strips added to further enhance their sealing performance.

Good toughness and durable

PP has moderate hardness; unlike PS and PET, which are highly brittle, it is unlikely to break or deform even if dropped. As a result, it is ideal for portable pill cases and travel-sized pill cases.

Excellent processing performance

Pill boxes made from PP material can easily incorporate compartments, flip-top lids, and snap-fit mechanisms. In particular, the flip-top design remains intact even after thousands of folds.

High cost performance

The cost is lower than materials like ABS, giving it a clear advantage in mass production of pill boxes. The PP pill boxes are recyclable and meet environmental standards.

Disadvantages of using PP material to manufacture pill box

boxes made of PP are highly transparent, but they have severe scratches

These scratches may not be visible during daily use, but will become apparent when held up to light. They also exhibit significant.

Avoid direct sunlight

Ultraviolet light accelerates the aging of PP materials, causing them to yellow and become brittle.

Weak surface adhesion

PP pill boxes require surface treatment to ensure the quality of the printing. (Some pill box factories produce very poor printing quality. The print will peel off easily with a fingernail. Please be careful when purchasing.)

Insufficient rigidity

Compared to engineering plastics such as ABS, PP is relatively soft. The pill box may undergo slight deformation when subjected to prolonged stress.

Flammable

PP material is a flammable plastic, and should be kept away from open flames during daily use.

2. ABS material

ABS, short for acrylonitrile-butadiene-styrene copolymer.
It is an engineering plastic. ABS pill boxes are harder and more durable than ordinary pill boxes.

Advantages of using ABS material to manufacture pill box

High hardness, good texture, high-end
1. ABS pill boxes have a smooth surface with a high gloss finish and feel comfortable to the touch.
2. Compared to PP pill boxes, ABS pill boxes are sturdier and more scratch-resistant. (many PP pill boxes have noticeable scratches)

Dimensionally stable and not easily deformed

The ABS injection molding process offers higher precision. It enables the precise manufacturing of snap fasteners, lids, and compartments, ensuring smooth opening and closing as well as a snug fit.

Easy to print and color, and looks more beautiful

The material takes dye well, resulting in vibrant, even colors. It is suitable for screen printing, pad printing, spray painting, and electroplating.

Good processing performance

Suitable for complex structures: multi-compartment, hinge, snap-fit, etc.

ABS material to manufacture pillboxes (something you must know if you manufacture pill box)

High temperature resistance

Normal operating temperature is 60~80℃. Do not scald with boiling water or microwave. High temperature can easily cause deformation.

Is higher than that of PP, PS and other materials

Higher cost, higher positioning.

Food/pharmaceutical safety is not as good as PP

In pill boxes, ABS is typically used for the outer shell and outer packaging. It is not suitable for inner packaging that comes into direct contact with tablets.

3. PS materials

PS (polystyrene) is a thermoplastic polymerized from styrene monomers.

Advantages of PS material

Good light transmission performance
PS has a light transmittance of over 90%, which is significantly higher than that of PP and ABS. It is ideal for making transparent lids.

Excellent processing performance

PS material can be easily machined into complex shapes and thin-walled structures. In addition, it produces smooth surfaces that are ideal for screen printing and spray painting.

Low cost

PS material is less expensive than ABS material and offers better value for money.

Disadvantages of PS material

The pill box made are brittle and have poor drop resistance

GPPS is extremely brittle and breaks easily if dropped or subjected to impact. Even HIPS is far less impact-resistant than PP and ABS. PS is not suitable for use as the sole material in pill boxes.

Poor high temperature resistance

When exposed to hot water or high temperatures, it softens and warps.

Do not directly contact medicine

Standard PS material is non-toxic, but prolonged contact with tablets and capsules may cause it to leach trace amounts of substances. Therefore, it is not recommended for use in inner liners that come into direct contact with medications; this material is suitable only for outer packaging.

Significant low-temperature brittleness

In environments below 0°C, the brittleness increases dramatically, and even HIPS becomes brittle and prone to cracking. This type of pill box cannot be used in extremely cold environments.

Chemical resistance is generally
PS material is highly susceptible to corrosion by organic solvents; upon contact, it turns white and cracks.

Okay, those are the three most commonly used materials for plastic pill boxes. Of course, there are also other plastic materials like PC, but they are not very common, so I won’t go into detail here (maybe another time, haha). Next, let’s take a look at aluminum alloy materials.

Aluminum alloy pill box – high-end, textured, expensive

That’s right—my take on aluminum alloy pill boxes is that they’re high-end and pricey. Aluminum alloy is considered a premium material for pill boxes. They’re perfect for users who are looking for stylish, visually appealing pill boxes.

Advantages of aluminum alloy pillbox

Superior sealing and waterproof performance

The aluminum alloy pill box is equipped with a high-quality sealing ring, which has a super strong sealing and waterproof effect, and can completely isolate moisture and prevent moisture and oxidation failure.

Lightweight metal, strong and acid-resistant

It’s made of metal, so you don’t need to worry about it being too sturdy. (You might not even be able to break it by running it over with a car.)

Chemically resistant
Aluminum alloy pill box are resistant to chemical corrosion, can store special medicines, and will not react with any medicine ingredients.

Durable and looks new for a long time

Aluminum alloy pillboxes are typically anodized, making them rust-proof, scratch-proof, corrosion-resistant, and colorfast. They maintain a new appearance even in humid environments.

With its high-quality feel
This aluminum alloy pill box is perfect for gifting. Its metallic appearance and smooth surface make it stand out from other types of pill box, making it a premium gift for family and friends.

Disadvantages of aluminum alloy pill box

expensive

That’s right, it’s expensive. Compared to plastic pillboxes, metal pill boxes have higher production costs, so their selling price is naturally much higher.

The user experience is poor in low-temperature environments

Since it’s made of metal, the surface temperature is very low in low-temperature environments, but this doesn’t affect daily use.

With its high-quality feel
This aluminum alloy pill box is perfect for gifting. Its metallic appearance and smooth surface make it stand out from other types of pill box, making it a premium gift for family and friends.

Most metal pill boxes on the market now are made of aluminum alloy. Of course, I’ve also seen titanium pill boxes on the market, but I don’t know if anyone has seen them. Those pill boxes are quite expensive, so I won’t go into detail.

Bamboo pill box – An environmentally friendly natural wooden pill box

Bamboo pill box are pill box made from bamboo. Made from natural bamboo, they are suitable for consumers who value environmental protection and appreciate nature. These pill box are quite unique and not commonly found on the market.

Advantages of bamboo pill box

Environmentally friendly and renewable
Bamboo pill box are green, biodegradable, and environmentally friendly. Bamboo grows quickly, is renewable, and can naturally degrade, aligning with the concept of a green and low-carbon lifestyle.

Natural texture, also decorative

Bamboo pill box have natural textures and a warm feel, which distinguishes them from the industrial feel of plastic and metal, adding a natural touch to the home.

Non-toxic and safe, suitable for a wide range of people

Natural bamboo is non-toxic, odorless, and free of chemical additives, ensuring the safety of medicine storage and making it a safe choice for medicine storage.

Disadvantages of bamboo pill box

Not moisture-proof, prone to mold

Bamboo is a natural material with poor water resistance and is prone to mold. It should not be placed in a humid environment for extended periods.

Security Question

Although bamboo is a natural material, most pill box made of bamboo or wood on the market still use glue to bond the materials, and the safety of the glue cannot be guaranteed.

Expensive

Similar to metal pillboxes, they are expensive, making them suitable for a small group of customers or simply as decorative items.
