Blow-molded bottles: mostly made of PET. There are three types of lids: Qianqiu lid, flip lid and screw lid. Blow molding is directly blown into preforms. The characteristic is that there is a bump on the bottom of the bottle. It is brighter in light.
Blow-injection bottle: The material is mostly PP or PE. There are three types of lids: Qianqiu lid, flip lid and screw lid. Blow-injection bottle is a process that combines blow-injection and blow-molding, and only requires one mold. The characteristic is that there is an adhesive line at the bottom of the bottle.
Aluminum-plastic hose: the innermost is PE material and the outside is aluminum packaging. And for offset printing. After cutting, roll up. According to the tube head, it is divided into round tube, flat tube and oval tube. Price: round tube<ellipse tube<flat tube.
All-plastic hose: all are PE material, and the hose is first pulled out and then cut and offset printing, silk printing, hot stamping. According to the tube head, it is divided into round tube, flat tube and oval tube. Price: round tube<ellipse tube<flat tube.
Nozzle, lotion pump, hand washing pump and length measurement
Nozzle: bayonet (half bayonet aluminum, full bayonet aluminum), the screw is all plastic, but some are covered with a layer of aluminum cover and a layer of anodized aluminum.
Lotion pump: It is divided into vacuum and suction tube, both of which are screw ports. The screw cap and head cap can also be covered with a layer of anodized aluminum. Divided into two kinds of sharp bill and duck bill.
Hand-washing pump: The diameter is too large, all with screw mouth. The screw cap and head cap can also be covered with a layer of anodized aluminum. Generally, steps are threaded, and those without steps are left and right knobs.
Length measurement: the length of the sub-pipette (from the gasket to the end of the hose or the length of the FBOG). Exposed length. And the length measured under the hood (equal to the length from the bottle shoulder to the bottle bottom).
Specification classification: It mainly depends on the product inner diameter (the inner diameter is the innermost diameter of the pump) or the height of the large circle.
Nozzle: 15/18/20 MM all plastic is also divided into 18/20/24
Lotion pump: 18/20/24 MM
Hand washing pump: 24/28/32(33) MM
Large circle height: 400/410/415 (only the pure specification code is not the actual height)
Note: The expression of specification classification is such as: lotion pump: 24/415
Metering measurement method: (actually the dose of liquid sprayed by the nozzle at one time) There are two methods: peeling measurement method and absolute value measurement method. The error is within 0.02g. The size of the pump body is also used to distinguish the measurement.
