With the upgrading of consumers' preference for product packaging and a new understanding of brands, packaging design is required to keep pace with the times. Innovation is the soul of packaging design and the core driving force for the survival and development of enterprises.

In the era of social media, everything is a medium, and products are marketing. Product packaging has gained unprecedented value. In addition to maintaining its original packaging function, it also carries the added value of the product. A packaging bag is not just a packaging, but also the best advertising platform for its own products, and it is a key tool to promote the "connection" and interaction between brands and users.

Most plastic raw materials are transparent or milky white, while precision plastic parts often have various requirements for color. Parts in optical instruments need to be black to prevent light leakage and eliminate stray light, and appearance parts often use different colors according to design needs. Therefore, before the processing of plastic products, dyeing is required, that is, different amounts of dyes are mixed in a certain proportion in the plastic. There are three methods for dyeing thermoplastic plastics:

Dry dyeing method

A certain proportion of dye and plastic granules are put into a rotating drum, and 0.01%~0.1% zinc stearate or white mineral oil is added as a wetting agent to make the plastic easy to bond with the dye. The drum is rotated to ensure that the plastic and dye are completely and evenly mixed.

Extrusion dyeing method

This method first mixes the dye and plastic according to the dry dyeing method, and then uses a special extruder to extrude it into a thin strip, which is then cut into granules. This method has good color mixing and helps to disperse poor dyes.

Dry thick dyeing method

This method is basically the same as the extrusion dyeing method, except that the proportion of dye in the plastic is usually more than 10 times higher. When injection molding, multiple times the original color plastic can be added to dilute it.
