What is the difference between plastic bottles and glass bottles for cosmetics?

1. cosmetic glass bottles:

Glass bottle is a traditional packing product. Its characteristics are bright, transparent, chemical stability, airtight and easy to shape. But it is heavy and easy to break. 80%-90% of glass packaging containers are glass bottles and cans. Generally, the density of sodium calcium glass bottle is 2.5-2.6g/cm3, the brittleness is large, and the thermal conductivity is low. The use of metal ion colorant can be made into emerald green, dark green, light blue and amber glass. The advantages of glass packaging container: (1) good chemical stability, non-toxic, clean, without any adverse effects on the packaging; (2) the barrier is good, can provide good quality conditions; (3) good transparency, the contents clearly visible; (4) good rigidity, deformation; (5) processing, can be processed into a variety of shapes; (6) the temperature is well tolerated, but also high temperature sterilization, low temperature storage; (7) abundant raw materials, Recyclable repeated use, no pollution to the environment. Glass packaging container defects; (1) brittleness is big, easy to break; (2) heavy weight, high transport costs; (3) processing energy consumption, serious environmental pollution; (4) poor printing performance.

2. cosmetic plastic bottles:

Plastic is a synthetic polymer materials, various kinds of advantages are: (1) good mechanical performance, light weight, convenient transportation, convenient carrying and use; (2) the permeability resistance, good sealing, high transparency; (3) the processing performance is good, can be made into various sizes of bottles, caps, bags, film and composite packaging materials; (4) decorative coloring and printing performance. Drug labels, instructions, labels and bar codes can be directly inkjet or printed on plastic materials and will not fall off; (5) good chemical stability, low toxicity, sanitation and safety. The cover of the medicine can be made into a safety cover or a pressure cover, as well as an anti-counterfeit label, etc.. The disadvantages of plastic packaging containers are that they are easy to carry with the static electricity, the surface is easy to pollute, and the waste will cause environmental pollution, and recycling is difficult.

You can see from the above comparison, the two have different advantages and disadvantages, but on the whole, cosmetics bottles of good sealing performance, stable chemical properties, and high quality material, can effectively guarantee the contents of long time is not bad, is the ideal choice for cosmetic packaging.
