Filling and packaging processes are important factors that greatly affect the quality of gel nail polish. Nichibi offers a range of gel nail polish filling and processing services based on the theme of "high quality with attention to detail, worthy of being Made In Japan". Our integrated responsibility system from bulk production to final processing, such as filling and packaging, enables us to respond quickly.

Fresh packing filling
within 10 seconds
from filling to capping
Compared to mechanical filling, manual filling inevitably takes longer, with a longer time between filling and lid-tightening, and the risk of dust contamination due to the gel nail being exposed to air while the lid is still open. The ideal is to tighten the lid as soon as possible after filling to reduce the risk of foreign object contamination and improve quality. At Nichibi, the process is designed to minimise the time the bulk is exposed to air and to cap the product within 10 seconds after filling, so that the freshly made gel nails are delivered to the customer in a best condition.
All-stainless steel filling machines for hygienic filling of high-viscosity gel nails.
The precision rigid Japanese cylinder allows the filling volume to be set from a minimum of 1g to 0.5g in 0.5g increments. Filling from container type to polish bottles can be done accurately and speedily. Various precision cylinders are available to suit different capacities. We can fill small quantities such as samples to more than 100g at an overwhelming speed.


Containers are cleaned each time using a container washing machine to remove foreign matter and dust from the containers before filling.
If gel nail polish is filled with dust or packing paper scraps adhering to the container due to static electricity, dust can get into the product, causing roughness and discomfort in the feel of the product and a significant drop in quality. In order to thoroughly prevent contamination, the containers are washed in a container washing machine immediately before filling and are visually inspected to ensure that they are clean before filling.
LOT number printing upgrades your products to a more reliable quality.
Manual LOT stamping is used for small-quantity production, but it looks ugly and terrible. Nichibi has introduced the latest model of Inkjet LOT number printing machine, which enables accurate and beautiful LOT printing in the designated position. In addition to LOT printing as required by the Pharmaceutical Machine Law, we can also print production dates and expiry dates at will.


Filling is carried out in a dedicated hygienic and clean filling room, specialising in gel nail filling.
Space control to "Improve Air Quality" is key to achieving high-quality gel nail production. In order to improve the cleanliness of the filling room, workers enter the room after wearing clean clothes, taking an air shower, and sanitizing their hands and fingers according to the entry procedure based on cosmetics GMP. The humidity in the filling room is controlled to 60% to prevent dust and static electricity. In addition, HEPA filters are used to purify the air at all times, and ionizers are installed to eliminate static electricity throughout the entire filling room, which significantly prevents dust from adhering to the products.
Cosmetics GMP has been introduced to support high-quality filling and to maintain quality control.
We carefully fill our customers' products in a clean space that complies with cosmetics GMP. We have established more than 100 rules for the filling process, and we have a strict control system in place to prevent contamination of foreign substances, which can affect the quality of cosmetics. For example, the filling room is used only for filling, and labeling, which generates dust, is done in a separate room. We always do our best to improve quality control so that our customers can trust us with filling with peace of mind.

Completely Custom-Made Only for the most particular customers, even in small lots.
To enhance your brand, we recommends completely custom-made packaging, even in small lots. We can provide everything from containers, labels, opening seals, shrink-wrap processing and packaging to meet your requirements.

Shrink-Processing
By wrapping the product with shrink film, it prevents stains, improves virginity, and improves the image.

High-frequency Aluminium Sealer
All sealer processes, which were not safe for manual crimping, are sealed with a conveyor-type high-frequency sealer machine. Various types of sealer materials are available, including aluminium types and those with logos.

Cosmetic packaging assembly
Why not place your products in a cosmetic package like a standard cosmetic product? Besides assembling cosmetic boxes, we also design and create low-cost cosmetic packages.
Should you have any question, please feel free to contact with our staff who is familiar with the Pharmaceutical Machinery Law or anything regarding Cosmetics Sales.
Nichibi also accepts filling of gel nail polish other than Nichibi's product. We can also perform component analysis tests to ensure that gel nail polish products brought in by customers can be sold as gel nail polish in Japan and overseas, and we can also handle administrative procedures quickly and efficiently. There are many cases in which gel nail polish products are made up of ingredients that do not have inci names, which may cause problems such as not being able to export. Please consult with Nichibi's regulatory affairs team first. If you have any questions about filling, please feel free to contact us via our inquiry form or by phone.
