Cosmetic packaging bottles and jars come in a wide range of shapes and sizes to meet the needs of different products and consumers. One important aspect of cosmetic packaging is the neck size, which refers to the diameter of the opening at the top of the bottle or jar. The neck size determines the size and type of closure that can be used, as well as the ease of filling and dispensing the product.
Here are some typical neck sizes for cosmetic packaging bottles and jars:
18/410: This is a very common neck size for small bottles and jars, such as those used for samples or travel-sized products. Closures for this neck size include screw-on caps, snap-on caps, and pumps.
20/410: This neck size is slightly larger than 18/410 and is often used for products that require a more precise dispensing method, such as serums or liquid foundations. Closures for this neck size include pumps, droppers, and sprayers.
24/410: This neck size is larger than 18/410 and 20/410 and is often used for larger bottles and jars, such as those used for lotions, creams, and shampoos. Closures for this neck size include screw-on caps, snap-on caps, and pumps.
28/410: This neck size is even larger than 24/410 and is often used for jumbo-sized bottles and jars, such as those used for body wash or large quantities of lotion. Closures for this neck size include screw-on caps and pumps.
33/410: This neck size is similar to 28/410 but is slightly larger, making it suitable for even larger bottles and jars. Closures for this neck size include screw-on caps and pumps.
It’s important to choose the right neck size for your cosmetic packaging to ensure that the closure fits properly and the product can be dispensed easily. In addition to the neck size, other factors to consider when choosing cosmetic packaging include the material, shape, and design of the bottle or jar.
In addition to the neck sizes mentioned above, there are also other neck sizes that are commonly used in the cosmetics industry. Here are a few more examples:
15/415: This neck size is smaller than 18/410 and is often used for very small bottles and jars, such as those used for samples or travel-sized products. Closures for this neck size include screw-on caps and snap-on caps.
22/415: This neck size is larger than 18/410 and is often used for products that require a more precise dispensing method, such as serums or liquid foundations. Closures for this neck size include pumps, droppers, and sprayers.
38/400: This neck size is larger than 28/410 and 33/410 and is often used for jumbo-sized bottles and jars, such as those used for body wash or large quantities of lotion. Closures for this neck size include screw-on caps and pumps.
It’s important to note that neck sizes are not standardized across the cosmetics industry, so it’s always a good idea to check with your supplier to ensure that you are using the correct size for your specific product.
In addition to the neck size, there are also other factors to consider when choosing cosmetic packaging, such as the material, shape, and design of the bottle or jar. For example, some materials, such as glass, may be more suitable for certain products than others, and the shape and design of the packaging can have a significant impact on the overall appearance and appeal of the product.
Overall, the neck size of cosmetic packaging bottles and jars plays a crucial role in the functionality and appeal of the product. By choosing the right neck size for your specific product, you can ensure that it can be dispensed easily and attractively, ultimately leading to a better experience for your customers.
