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 tank. The density of sodium calcium glass bottle is usually 2.5-2.6g/cm3, the brittleness is large and the thermal conductivity is low. The use of metal ion colorants can be made into green, dark green, light green, 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. The defects of glass packaging container; (1) big brittleness, easy to break; (2) large weight, high transportation cost; (3) high energy consumption, serious environmental pollution in processing; (4) poor printing performance.
Plastic plastic bottle:
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, barcodes can be directly inkjet or printed on plastic materials, and will not fall off. (5) chemical stability is good, toxicity is weak, 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.
From the above comparison, two each have 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.
