As far as the current situation is concerned, plastic bottle packaging has obvious advantages. It is light and cheap, and can be made into various sizes with transparent or opaque appearance. At the same time, the plastic packaging delivers good printing perforamnce. The manual, logo and bar code can be directly printed on the surface of the container by means of heat transfer printing, inkjet printing, printing and other methods. And in recent years, the application of PET resin in the application of cosmetic containers has developed rapidly, which has contributed to the great revolution of replacing glass bottles with plastics. Plastic products have occupied more than 80% of the cosmetics packaging market, and they have become the most important packaging containers for cosmetics.
Compared with the proportion of plastic packaging, the proportion of glass bottle packaging in cosmetic is small, which is less than 8%. However, glass packaging still has irreplaceable advantages in this field. In the short term, it is still the preferred material for high-end cosmetics. The reasons for this situation are as follows.
First, the quality of glass packaging is better than that of plastic bottles. Nobleness and elegance are the charms of glass bottles. Glass bottles can be made into frosted or transparent style. At the same time, the massiness of glass bottles can double the trust of consumers and improve the grade of cosmetics, which can not be achieved by plastic packaging. At present, most perfumes are packaged in glass bottles. For example, packaging design of the female perfume BVLGARI, made in Italy, inherits the tradition of delicacy and excellency. The fairshaped frosted glass bottles highlight its simple lines, and the mildness of its emerald bottle body, conveying pure, fresh, graceful and amicable characteristics.
Second, glass packaging is more airtight. As for cosmetics with whitening and nourishing effects, they contain a lot of nutrients just like food. As a result, they are prone to get oxidized, and require high airtight packaging insulate them from oxygen. In addition, volatile perfume also requires high barrier packaging. Glass bottles have strong barrier property and are undoubtedly more competent than plastic bottles in protecting the contents. Therefore, glass bottle packaging is still the first choice for some high-end cosmetics.
