The manufacturing process of plastic cosmetic packaging - how do lip balm tubes custom printing work?
The plastic packaging has excellent transparency, the light transmittance is more than 92%, and the anti-aging performance is good. At present, there are many kinds of plastic cosmetic packaging containers on the market, with rich colors and excellent comprehensive performance, providing designers with a variety of choices, such as injection dyeing, surface bronzing, printing, spraying, vacuum coating, and other processes.
This time I mainly introduce the hot-stamping process - empty lip balm tube
The hot-stamping process, simply put, is to imprint the hot-stamping paper on the surface of the product by heating and pressurizing the silicone plate or galvanized plate, so that the product is branded with the corresponding font content.
A reasonable tube holder is designed according to the shape of the product so that the hot content of the product does not shift, the upper and lower color registration is accurate, and it conforms to the industry standard. For some irregular-shaped products, several sets of tooling can be designed to shorten the time during the machine adjustment process and to achieve accurate hot stamping and color registration.
1. For the conical flask, you can make a set of free swing angles to adjust. A set of universal fixtures are made for the hot method of special-shaped products, and the products can be rotated freely.
2. For the inlaid hot-stamping method, a set of 360° free rotating fixtures can be made.
3. Several sets of fixtures can also be designed for other products that are difficult to locate.
In production, we should set the required process parameters according to the content and requirements of the product. Generally speaking, the higher the temperature of the hot-stamping plate, the shorter the hot-stamping time, and this time needs to be adjusted repeatedly. When the three items of time, pressure, and temperature are in focus, the hot product will be bright and strong in adhesion.
Stamping steps: First of all, we need to carry out electrostatic dust blowing treatment on the surface of the product to ensure that no particles, flying silk and other dust are adsorbed on the surface of the semi-finished product. Secondly, after dedusting, we should put the semi-finished product into a jig that can be positioned for surface font hot-stamping.
