Dec 06, 2017

Cosmetic glass bottle:

Glass bottle is a traditional packaging product. Its characteristics are: bright and transparent, good chemical stability, air permeability, easy to form, but large weight, easy to break. The 80%-90% of the glass packing container is a glass bottle and a jar.

The advantages of glass packaging containers:

(1) good chemical stability, nontoxic and tasteless, sanitary and clean, without any adverse effects on packaging;

(2) good barrier property and good quality condition.

(3) the transparency is good, the interior is clearly visible.

(4) the rigidity is good, and it is not easy to deform;

(5) good molding and processing, can be processed into a variety of shapes;

(6) good temperature tolerance, high temperature sterilization, and also can be stored at low temperature.

(7) rich in raw materials, recyclable and reusable, and no pollution to the environment.

The shortcomings of the glass packaging container;

(1) brittleness is large and easy to break.

(2) large weight and high transportation cost;

(3) high energy consumption and serious environmental pollution in processing.

(4) poor printing performance.

Cosmetic plastic bottle:

Plastic is a polymer synthetic material with many kinds, and the advantages are:

(1) good mechanical properties, light weight, convenient storage and transportation, easy to carry and use;

(2) permeability resistance, good sealing and high transparency;

(3) good processing performance, can be made into various sizes of bottles, covers, films, bags and composite packaging materials;

(4) good decorative coloring and printing performance. Drug signs, instructions, signs, and bar codes can be directly inkjet or printed on plastic materials and will not fall off.

(5) good chemical stability, weak toxicity, health and safety. The cover of a drug can be made into an insurance cover or a pressure cover, as well as a anti counterfeiting sign and so on.

The disadvantages of plastic packaging containers are that it is easy to carry static electricity, the surface is easy to pollute, and the discarded material will cause environmental pollution, and it is difficult to recycle.
