Lotion Bottle Use purpose

Plastic bottles have different classification methods, according to the purpose of plastic bottles are divided into cosmetic bottles, health bottles, capsules and so on. So, we from another classification method, plastic bottle manufacturers according to the different characteristics of the use of various plastic bottles, plastic bottles are usually divided into general plastic bottles, plastic bottles and special plastic bottles three types. General plastic bottles generally refers to the production of large, wide use, good shape, cheap plastic. There are five varieties of general plastic bottles, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and propylene-butadiene-styrene copolymer (ABS ). They are all thermoplastics.

Engineering plastic bottles generally can withstand a certain external force, with good mechanical properties and high resistance, low temperature performance, dimensional stability is better, can be used as engineering structure of plastic, such as polyamide, polysulfone and so on. In the engineering plastics and it will be divided into general engineering plastics and special engineering plastics two categories. General engineering plastics include: polyamide, polyoxymethylene, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methyl pentene polymer, vinyl alcohol copolymer. Special engineering plastics and cross-linked non-cross-type of the points. Crosslinking type are: polyaminobis maleamide, polytriazine, crosslinked polyimide, heat-resistant epoxy tree fingers and so on. Non-crosslinking type is: polysulfone, polyether sulfone, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK) and so on.

Special plastic bottles generally refers to a special function, can be used for aviation, aerospace and other special applications of plastic. Such as fluorine plastic and silicone has a prominent high temperature, self-lubricating and other special features, enhance the plastic and foam with high strength, high cushioning and other special properties, these plastics are special category of plastic.

1, plastic bottle material is usually PP, PE, K material, AS, ABS, acrylic, PET and so on.

2, usually used for cosmetic containers wall thicker cream bottles, caps, corks, gaskets, pump head, dust cover for injection molding; PET blowing for the two-step molding, tube embryo for injection molding, finished packaging For blowing. Others such as container wall thinner bottle, washing bottle for blowing.

3, PET material for the environmentally friendly materials, with high barrier, light, not broken characteristics, resistance to chemical resistance, transparency and strong, can be made pearl, colored, magnetic white, transparent, widely used in the installation of gel water. Bottle is generally standard 16 #, 18 #, 22 #, 24 # caliber, can be equipped with pump head.

4, acrylic material for the injection molding bottle, chemical resistance is poor, generally can not directly install the paste, need to be equipped with bladder barrier, filling is not easy to prevent the paste into the liner and acrylic bottles, In order to avoid cracking, transport packaging requirements are higher, because the scratches look particularly obvious, high permeability, feeling the wall is particularly thick, but the price is quite expensive.

5, AS, ABS: AS transparency is better in ABS, and toughness is better.
