Some knowledge for plastic cosmetic tubes

Plastic cosmetic tubes are favored by many cosmetic manufacturers for their light weight, portability, durability, recyclability, ease of squeezing, good processing performance and printability. They are widely used in the packaging of cosmetic soft tube products such as facial cleansers (facial cleansers, etc.), skin care products (various eye creams, moisturizing creams, nourishing creams, cold creams and sunscreens, etc.) and beauty and hair care products (shampoos, conditioners, lipsticks, etc.).

For those who are not familiar with plastic cosmetic tubes, designing the draft by themselves can be a nerve-racking task. Once a mistake is made, the entire project could be ruined. High-quality suppliers will design relatively simple drafts for those who are not familiar with plastic cosmetic tubes. After the tube diameter and length are determined, they will provide a design area map. You just need to place the design content within the map area and center it. High-quality suppliers will also check and offer suggestions on your design and production process. For example, if the position of the photoelectric eye is wrong, they will inform you; if the color is not reasonable, they will remind you; if the specifications do not match the design, they will repeatedly remind you to modify the draft; for instance, whether the direction and readability of the barcode are qualified, whether the color separation and process can produce cosmetic soft tube, even small mistakes such as the draft not being curved, high-quality suppliers will check for you one by one.

The materials used must meet relevant hygiene standards, and the content of heavy metals, fluorescent agents and other harmful substances should be controlled within the prescribed range. For example, for plastic cosmetic tubes exported to the United States, the polyethylene (PE) and polypropylene (PP) used must meet the standards of the US Food and Drug Administration (FDA).

There are two filling methods for plastic cosmetic tubes: filling from the cosmetic soft tube tail and filling from the tube mouth. If it is filled from the tube mouth, when purchasing the plastic cosmetic tube, you must pay attention to whether the "size of the tube mouth and the size of the filling nozzle" are matched and whether it can be flexibly inserted into the tube. If it is filled from the tube tail, you need to box the plastic cosmetic tube and consider the head and tail direction of the product, and how to make the filling process convenient and fast. Secondly, you need to know whether the content filled during the filling process is "hot filling" or at room temperature. Moreover, the process of this product is often related to the design. You need to understand the essence of the filling production in advance to avoid problems and achieve high production efficiency.
