Plastic Bottles Or Glass Bottles Are Better For Cosmetics

Cosmetic glass bottles:

Glass bottles are traditional packaging products, and their characteristics are: bright and transparent, good chemical stability, airtight, easy to shape, but heavy, easy to break.80%-90% of glass packaging containers are glass bottles and cans.Usually, the density of sodium-calcium glass bottles is 2.5-2.6g/cm3, which has high brittleness and low thermal conductivity.The use of metal ion coloring agent can be made into emerald green, dark green, light blue, amber glass.Advantages of glass packaging container:

(1) Good chemical stability, non-toxic and odorless, sanitary and clean, without any adverse effects on the packaging;

(2) good barrier, can provide good quality conditions;

(3) good transparency, the contents can be clearly visible;

(4) good rigidity, not easy to deform;

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

(6) good temperature tolerance, high temperature sterilization, can also be low temperature storage;

(7) Rich in raw materials, can be recycled and reused, no pollution to the environment.The disadvantages of glass packaging container; (1) Brittleness is large and easy to be broken; (2) the weight is large, the transportation cost is high; (3) the processing energy consumption is large, serious pollution to the environment; (4) poor printing performance.

Plastic bottles for cosmetics:

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

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

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

(3) good processing performance, can be manufactured into a variety of sizes of bottles, caps, films, bags and composite packaging materials;

(4) good decorative coloring and printing performance.Drug labels, instructions, labels, and bar codes can be ink-jet or printed directly on plastic material and will not come off;

(5) good chemical stability, weak toxicity, health and safety.The LIDS of medicines can be made into safety or pressure caps, security labels, and so on.The disadvantage of plastic packaging container is that it is easy to carry static electricity, the surface is easy to pollute, the discarded material will cause environmental pollution, and the recycling is more difficult.
