Cosmetic Glass Bottle Packaging
Glass packaging products have the advantages of non-toxic,odorless,transparent and beautiful,good barrier properties,pressure resistance, high temperature resistance,etc.Compared with plastic,paper,metal and other packaging materials,glass packaging materials have relatively stable chemical properties and are the safest packaging materials at this stage.a packaging material.
1.Common types of glass packaging
Glass packaging materials are mainly used in cosmetics such as cream bottles,essences,toners and essential oil bottles.Glass packaging materials are mainly divided into three categories:main materials,auxiliary materials and special materials.Main materials mainly include silica sand(or quartz powder)soda ash(Na2co3),limestone(CaCO3):auxiliary materials mainly include clarifying agent (generally sulfate);special materials(generally it is an oxidizing agent,a physical decolorizing agent).
2.Advantages of glass packaging
Glass packaging is one of the four major materials in the packaging industry,with a market share of 15%.Due to its excellent characteristics and the continuous improvement of the manufacturing process,glass packaging materials can still meet the applications of most industries such as food and medicine at this stage.Glass packaging materials mainly have the following advantages:
A. The glass materials has excellent protective properties is airtight,moisture-proof,has ultraviolet shielding properties has good chemical stability is non-toxic and odorless and can effectively preserve the contents:
B. The glass has good transparency and is easy to shape,which can achieve the function of beautifying the product;
C. Glass packaging materials have strong plasticity and can be made into various styles of packaging materials to meet the diversity of commodities to a great extent;
D. Glass strengthening,lightweight technology and composite technology have developed to a certain extent,which has strengthened the adaptability to packaging,especially in disposable packaging materials,glass materials have strong advantages.
3. Disadvantages of glass packaging
Glass packaging materials also have disadvantages such as low impact resistance,easy damage when colliding,high transportation costs and good light transmission will deteriorate the contents:
First of all,environmental pollution is serious.In the mining of siliceous raw materials in my country,10% to 15% of the available ore is discarded.The average yield of hard sandstone does not exceed 60% and the output rate of quartz sand after beneficiation does not exceed 70%.Utilization is low.Excessive energy consumption and resource consumption are more serious to environmental pollution.Harmful gas,smoke,waste residue,etc.discharged during raw material processing,harmful gas,smoke,waste residue,etc.discharged during glass melting,waste water,waste oil.etc,discharged during processing,all environment:
Second,production efficiency is low,my country’s glass packaging technology level is backward,product added value is low,product design lacks creativity and market competitiveness is insufficient.Although my country has made great progress in glass smelting technology,glass forming technology,raw materials quality control,etc.,there is still a big gap between us and developed countries in the entire international market;
Third,the recovery and reuse rate is low.The glass recovery rate in Japan is about 50%,that in Germany is about 80% and that in my country is only 20%.This will generate a lot of waste,which is not conducive to my country’s sustainable development
