What kind of plastic cosmetic bottles?
Dongguan xiang Lin tell you
1, PET material for environmental protection, high barrier property, qualitative light, no broken properties, chemical resistance, transparency is extremely strong, can make magnetic bead light, color, white, transparent, widely used in hold gels water.
Bottle for general standard of 16 # #, # # 18, 22, 24 diameter, can be used with the pump head.
2, the material of plastic bottles are usually for PP, PE, K, AS, ABS, acrylic, PET, etc.
3, acrylic material for plastic bottle, chemical resistance is poorer, generally cannot directly paste, need to match the tank, filling not too full, prevent the paste into the bladder and acrylic bottle, lest produce cracks, transport packaging of the demand is higher, because of the cut after look particularly evident, high permeability, sensory on wall thickness, but the price is quite expensive.
4, usually used in cosmetics container wall thick cream bottle, bottle caps, bottle stoppers, gasket, pump head, dust cover for injection molding;
PET bottle blowing for two-step forming, tube embryos for injection molding, finished product packaging for the bottle blowing.
Other such as container wall thinner lotion bottle, washing bottle to bottle blowing.
5, AS, ABS, AS better transparency in ABS, and good toughness.
At present more popular is acrylic plastic cosmetic packaging bottle, acrylic material packing bottle has the following advantages: 1, with crystalline transparency, light transmittance over 92%, the light is downy, clear vision, dye acrylic and has a good exhibition effect.
2, acrylic board has excellent weather resistance, higher surface hardness and surface luster, as well as a better high temperature performance.
3, yakeli board has good processing performance, can use thermoforming, also can use mechanical processing way.
4, transparent acrylic has to match the light transmittance of glass, but the density is only half of the glass.
In addition, it is not as fragile as glass, even if broken, will not like glass to form the sharp fragments.
5, acrylic plate wear resistance in aluminum, good stability and corrosion resistance to a variety of chemicals.
6, acrylic board has good printing and coating, using the appropriate printing and spraying process, gives an acrylic products ideal surface decorative effect.
7, flame resistance: no spontaneous but belongs to flammable items, do not have self-extinguishing.
Characteristics: 1, the hardness hardness is the most can reflect pouring yakeli board, one of the production process and technical parameters is an important part of quality control.
Hardness can reflect the purity of raw materials PMMA sheet, weather resistance, high temperature resistance and so on.
Hardness will directly affect the plate bending deformation shrinkage, cracked surface will appear when processing, and so on and so forth.
Hardness is one of the judge yakeli board quality stand or fall hard targets, an average of rockwell hardness number 8, 9 degrees or so.
2, thickness (
Acrylic thickness is yakeli tolerance, so the acrylic tolerance control are the important of quality management and production technology.
Acrylic ISO7823 production has an international standard 3, transparency/whiteness strict raw material selected, advanced modern production technology and the formula to follow up production, to ensure that the plate excellent transparency and pure white.
After the flame polishing crystal clear.
Formal cosmetics should be marked on the outer packing: 1.
The hygiene licence.
