Choose glass bottle packaging or plastic bottle packaging?

Cosmetic glass bottle:

Glass bottles are traditional packaging products, which are characterized by: bright and transparent, good chemical stability, airtight, easy to form, but heavy and easy to break. 80%-90% of glass packaging containers are glass bottles and cans. Usually the density of soda lime glass bottle is 2.5-2.6g/cm3, which is brittle and has low thermal conductivity. The use of metal ion colorants can be used to make glass of various colors such as emerald green, dark green, light cyan, amber and so on.

Advantages of glass packaging containers:

Cosmetic glass bottle

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

(2) Good barrier properties and can provide good quality guarantee conditions;

(3) Good transparency, the contents are clearly visible;

(4) Good rigidity and not easy to deform;

(5) Good formability and can be processed into various shapes;

(6) Good temperature tolerance, high temperature sterilization, and low temperature storage;

(7) The raw materials are abundant, can be recycled and reused, and have no pollution to the environment.

Disadvantages of glass packaging containers:

(1) It is brittle and easy to break;

(2) The weight is large and the transportation cost is high;

(3) High energy consumption during processing and serious environmental pollution;

(4) poor printing performance.

Cosmetic plastic bottle

Cosmetic plastic bottle:

Plastic is a polymer composite material, and there are many types. The advantages are:

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

(2) Barrier, good sealing and high transparency;

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

(4) Good 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) Good chemical stability, weak toxicity, hygiene and safety. The cover of the medicine can be made into a safety cover or a pressure cover, as well as an anti-counterfeiting mark and so on. The disadvantage of plastic packaging containers is that it is easy to carry static electricity, the surface is easy to be polluted, the discarded objects will cause environmental pollution, and it is difficult to recycle.

From the above comparison, it can be seen that both have their own advantages and disadvantages, but on the whole, cosmetic glass bottles have good sealing performance, stable chemical properties, and high-grade materials, which can effectively ensure that the contents will not deteriorate for a long time, which is a good choice for cosmetic packaging. Ideal.
