The vacuum bottle product process is composed of a lid, a shoulder sleeve, a vacuum pump, and a piston, and it is used by air pressure. The nozzles that are matched have a chicken beak tip (either all-plastic or anodized aluminum), and the duckbill flat head is covered with a layer of plastic.

The internal composition of the perfume bottle is glass and aluminum outside (revolving and non-rotating according to the cap), PP bottle (all PP for small injection), and glass drip irrigation. The inner liner of the perfume bottle is mostly glass and PP. Large-capacity uses glass, because the storage time is longer, PP is suitable for small-capacity short-term storage. Most PCTA and PETG do not have perfume.

The inside of the aluminum-plastic hose is made of PE material and the outside is aluminum packaging. And for offset printing. After cutting, roll up. According to the tube head, there are round tubes, flat tubes and oval tubes. Price: round tube<ellipse tube<flat tube.


Usually used for cream bottles, caps, stoppers, gaskets, pump heads, and dust covers with thicker walls of cosmetic containers are injection molding; PET blow molding is two-step molding, tube embryo is injection molding, and the finished packaging is blow molding . Others, such as lotion bottles and washing bottles with thin container walls, are blown bottles.

 The PET material is an environmentally friendly material with high barrier properties, light weight, non-breaking characteristics, chemical resistance, and strong transparency. It can be made into pearlescent, colored, magnetic white, and transparent. It is widely used in gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, which can be used with pump head.

Acrylic is made of injection-molded bottle, which has poor chemical resistance. Generally, it cannot be directly filled with paste. It needs to be blocked by an inner tank. The filling is not easy to be too full to prevent the paste from entering between the inner tank and the acrylic bottle. Cracking, packaging requirements are high during transportation, it looks particularly obvious after scratches, has high permeability, and the sensory upper wall is very thick, but the price is quite expensive.
