The advantages and disadvantages of PETG
What are the advantages of PETG 1. In polymerization process with no chemical composition, in use process will not release the BPA, accord with environmental protection requirement and the FDA. 2. Clear and transparent, light transmittance & gt; 90%, fog degrees & lt; 1%, with crystalline luster. 3. Excellent no notched impact strength unceasingly, has notched impact strength on the basis of different grades in the 650 - 980 j/m between, can be comparable to the impact strength of PC. 4. Excellent chemical resistance, hydrolysis resistance can resist detergent, detergent, hydrocarbon solvents, oils, such as perfume corrosion; Can hydrolysis resistance in hot and humid environment. 5. High temperature resistant low thermal deformation temperature ( 热变形@ 0。 455MPa) According to different grades at 94 ℃ Between 109 ℃. 6. Good liquidity test conditions in 2. 16 KGF pressure, melt temperature of 280 ℃, refers to ( MI) According to different grades in 15. 3 - 29. 5. 7. Easy processing Jin Shi PETG available injection ( injection) , extrusion ( 挤压) , crowded blowing ( 循证医学) , injection blow ( ISBM) A variety of methods, such as processing. In general, use PC can normal production mold, do not need to change the Tritan? To production, production cycle time is very close. 8. Easy to secondary processing can be applied to the secondary processing methods include: UV glue bonding, ultrasonic welding, surface printing, spray painting, surface vacuum plating, etc. 9. Products small residual stress after injection, the residual stress is smaller than a PC, no subsequent annealing treatment. Products in use process due to the less chance of residual stress cracking, so the manufactured product is more durable.
What is the two in one tube and how to fill it in the rear? And the application of the product in skin care
Unlike a single branch tube, the most intuitive tube is a tube in the tube, which looks like a single branch, but can fill two kinds of material at the same time, at the same time extruding. When the material is not used, the material body is separated, and when used, mingling and merging.

What are the customers' concerns about cosmetic packaging enterprises
In the choice of cosmetics package enterprises, first of all to see whether the qualification of the enterprise is in line with the requirements of the national cosmetic package production. If the enterprise's qualification is blurred, it shows that the enterprise does not meet the national production requirements and the quality of the product can not be guaranteed. So when choosing cosmetic packaging enterprises, we must check the production qualification of enterprises.
Cosmetic tube field, where is the foothold in the future?
Nowadays, in order to meet the changing needs of consumers, whether it is basic skin care brands or efficacy brands, when most of them launch new series of products, they will launch matching products with instruments, aiming to realize the effective incorporation of brands through high-tech instruments.
