Glass cosmetics bottle

Its characteristics are: bright and transparent, good chemical stability, breathable, easy to shape, but heavy and broken. 80%-90% of glass packaging containers are glass bottles and cans. Soda lime glass bottles usually have a density of g/cm3, 2.5-2.6, high brittleness, and low thermal conductivity. Metal ion as a colorant can be made into a green, dark green, light cyan, amber glass.

  Advantages of glass cosmetic bottles:

(1) Good chemical stability, sanitary and clean, and have a bad influence on packaging;

(2) Good barrier properties and can provide good quality conditions;

(3) The transparency is good, and the contents are clearly visible;

(4) Good rigidity and not easy to deform;

(5) Good processability and can be processed into a variety of shapes;

(6) Good temperature resistance, high temperature resistance and low temperature storage;

(7) Easy to process;

Disadvantages of glass cosmetic bottles:

(1) Easy to break, heavy weight and high transportation cost;

(2) High energy consumption during processing and serious environmental pollution;

(3) Poor printing performance.

Plastic cosmetic bottle: plastic is a kind of polymer synthetic material, has the following advantages:

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

(2) Good wear resistance, sealing and transparency;

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

(4) Decorative coloring and printing performance.Signs, instructions, labels, bar codes can be directly ink-jet or printed on plastic materials, will not fall off;

(5) chemicals, good stability, weak toxicity, health.

The disadvantages of plastic packaging containers are easy to bring static electricity phenomenon, easy to pollute the surface, discarded things will cause environmental pollution, recycling site is difficult.

The above is the difference between the two, but on the whole, glass cosmetics bottle has good sealing performance, good chemical stability, and the material can not deteriorate for a long time, so it is the ideal material for packaging cosmetics.
