Hangzhou Lecos Packaging Co.,Ltd | Updated: May 28, 2018

Cosmetic glass bottle:

Glass bottle is a traditional packaging product, its characteristics are: bright and transparent, good chemical stability, impervious to air, easy to shape, but weight, easy to break. Eighty to ninety percent of glass packaging containers are glass bottles and cans. Generally, the density of sodium calcium glass bottles is 2.5-2.6g/cm3, with high brittleness and low thermal conductivity. Metal ion coloring agents can be used to produce emerald green, dark green, light green, amber glass. Advantages of glass packaging containers :(1) good chemical stability, non-toxic, tasteless, hygienic and clean, no adverse effects on the packaging; (2) good barrier and good quality guarantee; (3) good transparency and clear visibility of the contents; (4) good rigidity and no deformation; (5) good molding and processing capability, which can be processed into various types; (6) good temperature tolerance, high temperature sterilization, low temperature storage; (7) abundant raw materials, recyclable and reused, no pollution to the environment. Disadvantages of glass packaging containers; (1) high brittleness and easy to break; (2) heavy weight and high transportation cost; (3) high energy consumption and serious environmental pollution during processing; (4) poor printing performance.

Cosmetic plastic bottle:

(1) good mechanical properties, light weight, convenient storage and transportation, easy to carry and use; (2) resistance, good sealing and high transparency; (3) good processing performance, capable of producing bottles, covers, films, bags and composite packaging materials of various sizes; (4) good decorative coloring and printing performance. Drug identification, specification, label, barcode can be directly inked or printed on plastic material without falling off. (5) good chemical stability, weak toxicity, hygiene and safety. The lid of a medicine can be used as a cover or pressure cover, as well as anti-counterfeiting identification, etc. The disadvantage of plastic packaging container is that it is easy to carry static electricity, and the surface is easy to be polluted.

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, can yet be regarded as Choice of cosmetics packaging.
