Materials suitable for cosmetic packaging bottles

The cosmetics industry uses a variety of materials in its packaging, including plastics and metals, with glass being one of the oldest packaging materials. The following information provides detailed information about cosmetic packaging materials.

Glass Containers

Sand, known as silica, is the main component of glass, mixed with metal oxides, sodium carbonate, and other trace elements. Jars made of glass are popular for packaging emulsions because they are easy to take out the product with your fingers. The main advantage of glass is that it is decorative and has a clean appearance. The three main types of glass are borosilicate, treated soda-lime, and regular soda-lime. Each has unique chemical properties.

Borosilicate glass is more chemically inert than soda-lime glass because it contains boron and/or aluminum and zinc. The glass contains sodium hydroxide, which, after a year of storage, mixes with other ingredients and trace particles into the distilled water inside the glass container. Treated soda is used or stored for long periods of time, while regular soda is more chemically resistant and suitable for general-purpose packaging.

Smaller, thick-walled glass jars are used for eyeshadow, lip gloss, and cream products. Larger glass jars are used for foundation, makeup removers, creams, and powders. Amber glass jars are designed for bath and body products where the color is opaque. With the reduction of sodium ions, glass will become a more chemically resistant form of cosmetic packaging.

Plastic Containers

A wide variety of cosmetic packaging is made from plastic due to its convenience and hygienic properties. Unfortunately, plastic tends to create a lot of waste, and once opened, the product usually has to be consumed immediately. One of the main reasons why plastic is so popular is its low cost. It is also lightweight, flexible, strong and durable. On top of that, it is odorless and pleasant to the eye.

The main drawback of plastic is its physical stability, which makes it susceptible to absorption, stress cracking and cracking. Resistance to inks and other chemicals can limit its use in certain types of packaging.

The most commonly used plastic in cosmetic packaging is PP. Other plastics include PET and acrylic components. Acrylic plastic has the appearance of glass, but it does not break like glass. From an aesthetic point of view, plastic can be made into a variety of colors or hues, depending on the material.

Metal Containers

Cans and tubes are usually made of metals, such as aluminum or tin. Aluminum prevents bacterial growth and is one of the most recycled materials on the planet. Most collapsible tubes are made of aluminum, while tin and lead also make up a large percentage of cosmetic packaging.

Metals can provide the strongest protection for products by acting as unbreakable packaging. They can also protect products by protecting them from moisture or heat. For companies trying to convey an environmentally friendly image, metal is highly recyclable. Another major advantage is that metal can be made into a variety of shapes and sizes to avoid waste. Overall, metal is a cost-effective, long-lasting and sustainable solution. For example, metal cosmetic containers used in combination with plastics offer marketers a unique design option for the premium price segment.

Material Selection

The decision on structure and material determines the most appropriate packaging. The volume of the product affects the size and weight, which affects shipping, storage and cost. Products that oxidize quickly require sealed containers. Material selection is based on the following important factors:

Type of substance inside the container
Considerations of decoration, color, capacity
Product lifespan
Dimensions and weight of the product
Heat resistance
Physical, chemical and biological aspects of the product
Type of closure (screw, crimp, press, roll, friction)
Conclusion

Cosmetic packaging bottles embody the identity of the brand. Often the packaging is already seen by consumers as part of the product. Consider the purpose, advantages and disadvantages of certain materials. Consider material properties such as durability and sustainability and how they relate to retail conditions. Cosmetics need packaging that is both aesthetically pleasing and functional to be successful
