Cosmetics bottle manufacturers to introduce transparent plastic bottles and function
Nowadays the transparent plastic is widely used in people's life, but there are still some net friends also is not very understanding of transparent plastic, so, the next, dongguan cheung cosmetics bottle manufacturers to introduce in the transparent plastic bottle and its effect, net friends in need can be a good reference!
Is a kind of transparent plastic blow molding processing of color is transparent white plastic packaging container, after bottle preform injection molding processing to form intermediate products, and then after form plastic blow molding processing, namely ldpe-g-nvp forming principle.
Is through the transparent plastic raw materials for polyester class special materials through form a transparent bottle preform injection molding processing, transparent bottle preform after blow molding processing under certain pressure and temperature conditions, within the mold QiangMo volume expansion, according to the specifications mold is the thickness of highly transparent plastic bottles.
At present, the more transparent plastic used in medicine, drinks, mineral water, candy, seasoning, wrapping.
1, PET transparent plastic material: qualitative hard, good toughness, high strength, surface brightness, environmental non-toxic, transparent and a variety of color sheet.

3, PVC transparent plastic material: soft, strong toughness, good plasticity, but make it transparent and a variety of colors, the common purpose of transparent PVC packaging masked category plastic bottles.
Constant win to introduce you to the role of the transparent plastic packaging, as shown in the following: PMMA, commonly known as acrylic, transparency excellent material, the surface hardness is a bit low, easy to clean.
, and is suitable for production of transparent insulation parts and the strength of ordinary parts.
PS: colorless, transparent, pervious to light after PMMA, suitable for making insulating transparent parts.
Decoration and chemical equipment.
Optical instruments and other parts.
PC: colorless, transparent material, suitable for making small instrument parts, insulation transparent and shock resistant parts.
