Plastic and glass cosmetic bottles, relative?

We all know that most cosmetic is made of glass or plastic bottles, and these two kinds of material is each have each advantage. Then for consumers or cosmetics company, choose what kind of material is better? And listen to the small make up for everyone to explain:

cosmetics glass bottle

glass bottles for traditional packaging products, its characteristic is:

bright transparent, good chemical stability, airtight, easy molding, but the weight is big, easy to broken. - 80% of glass packaging container 90% of glass bottles, cans. The density of sodium calcium glass bottles of 2 is normally used. 5 - 2. 6 g/cm3, brittleness and low thermal conductivity. Use a metal ion colorants can be made into green, dark green, shallow blue, amber glass.

the advantages of glass packaging container:

( 1) Good chemical stability, non-toxic tasteless, clean health, had no any bad effect on packaging;

　　( 2) Good barrier property, it can provide good quality conditions;

　　( 3) Good transparency, built-in objects visible;

　　( 4) Good rigidity, out of shape not easily;

　　( 5) Forming good workability, can be processed into a variety of shape;

　　( 6) Good temperature resistance, high temperature sterilization, also can be stored at low temperature; ( 7) Abundant raw materials, reuse, recycle no pollution to the environment.

the shortcoming of glass packaging container:

( 1) Brittleness is big, easy and broken;

　　( 2) The weight is big, the high cost of transportation;

　　( 3) When processing large energy consumption, serious environmental pollution;

　　( 4) The printing performance is poor.

cosmetics bottles

plastic is the high polymer synthetic materials, sort is more, the advantage is:

( 1) Good mechanical performance, light weight, convenient transportation, easy to carry;

　　( 2) Permeability resistance, good sealing, high transparency;

　　( 3) Processing performance is good, can be made into all kinds of the size of the bottle, cap, thin films, bags and composite packaging materials;

　　( 4) Decorative coloring and printing performance is good. Drug identification, specification, and shown to sign, bar code can be directly inkjet or printed on the plastic material, and will not fall off;

　　( 5) Good chemical stability, toxicity, health and safety. The lid of the drug can make insurance cover or pressure cover, and anti-counterfeiting mark and so on. Plastic packaging containers on the downside, with static electricity, the surface easy to pollution, litter can cause environmental pollution, recycling more difficult.

can be seen from the above comparison, each have advantages and disadvantages, but overall, cosmetics glass bottle sealed performance is good, stable chemical properties, and high-grade material, can effectively guarantee the high quality content for a long time, is the ideal choice of the cosmetics packaging.
