Dongguan pet plastic bottle manufacturer
Pet plastic products is in the life is very common, for example, we often drink cosmetic make-up bottles, water bottles, etc. These are basically is made of food grade pet raw material injection molding, safe is beautiful, so what's the special pet materials will can bold use food grade? PET has the following advantages: 1. Have good mechanical properties, impact strength is 3 ~ 5 times of other films, the folding resistance. 2. Resistance to oil, fat, resistance to acid, dilute alkali, resistance to most solvents. 3. Pure PET heat resistant performance is not high, the thermal deformation temperature is only about 85 ℃, but enhanced greatly improved after treatment. After glass fiber enhanced the PET mechanics performance is similar to the PC, PA, such as engineering plastics, thermal deformation temperature can reach 225 ℃; PET heat aging, brittle temperature was minus 70 ℃, in - At 30 ℃ still has a certain toughness; PET is not easy to burn, yellow flame, burning oil dripping. 4. Gases and water vapor permeability is low, have excellent resistance odor gas, water, oil, and performance. 5. Block uv, high transparency, good gloss. 6. Non-toxic, tasteless, good health security, can be directly used in food packaging. PET is the height of milky white or light yellow crystalline polymer, surface smooth and glossy. Resistance to creep, fatigue resistance, friction resistance and good dimensional stability, wear small, high hardness, has the largest of thermoplastics toughness: electric insulation performance is good, affected by temperature is small, but the corona resistance is poor. Non-toxic, good weather resistance, chemical resistance stability, bibulous rate is low, resistance to dilute acid and organic solvents, but not hot water immersion, not alkali resistance. PET resin of high glass transition temperature, crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate, poor dimensional stability, crystallization of forming a brittleness, low heat resistance. Through crystallization nucleating agent and the agent and the improvement of glass fiber reinforced PET besides has the properties of PBT, still have the following characteristics. 1. Thermal deformation temperature and the long-term use of temperature is the highest of thermoplastic general engineering plastics 2. Because of the high heat resistance, enhance the PET in 250 ℃ soldering tin bath soak 10 s, little deformation does not change color, especially suitable for the preparation of soldering of electronic, electrical parts: 3. Bending strength 200 mpa, the elastic modulus of 4000 mpa, the creep and fatigue resistance is also very good, high surface hardness, mechanical properties similar to thermosetting plastic. 4. Due to the production of PET glycol used than the production of PBT, the price of butyl glycol used, almost half cheap, so PET resin and enhance the PET is the lowest price in engineering plastics, has the very high cost performance.

Cosmetic packaging is a subdivision field that has grown rapidly in recent yea
Cosmetics are commodities that every woman uses.
Simplified packaging design style is a design direction recognized by young people and modern culture.
Consumer trends are the driving force of packaging innovation, and big data analysis is to combine trend insights with packaging innovation.
In order to attract consumers, in recent years, businesses have put more and more effort on cosmetic packaging, and various novel and exquisite packaging have emerged one after another.
In addition to the production date, manufacturer, etc., what are the secrets of the neglected graphic symbols, words, and numbers on the outer packaging of cosmetics?
In addition to the most common barcodes, there are some unobtrusive small icons on cosmetic packaging that also represent very important information.
This common small open can logo means the shelf life after opening.
Research and Markets released the 2020 Packaging Innovation Trends Report-focusing on the latest trends in packaging innovation and the shift to more sustainable options.
Analysts said: 'Sustainability has become an important factor in today's consumers' purchasing decisions.
