Most of the cosmetic bottles we have seen on the market today have the following types, each with their own characteristics:
1. PET material is environmentally friendly material, with high barrier property, light weight, non-breaking property, chemical resistance, strong transparency, can be made into pearlescent, colored, magnetic white, transparent, widely used in the installation of gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, and can be used with the pump head.
2, the material of the plastic bottle is usually PP, PE, K material, AS, ABS, acrylic, PET and so on.
3, acrylic material for injection molding bottles, chemical resistance is poor, generally can not directly paste the paste, need to be equipped with a liner barrier, filling is not too full, to prevent the paste from entering between the liner and the acrylic bottle, In order to avoid cracking, the packaging requirements are higher during transportation, it is particularly obvious after scratching, the permeability is high, and the upper wall is very thick, but the price is quite expensive.
4, usually used in cosmetic containers, thicker cream bottles, caps, stoppers, gaskets, pump heads, dust covers for injection molding; PET blowing bottles for two-step molding, tube embryos for injection molding, finished packaging For blowing bottles. Other emulsion bottles such as thinner containers and washing bottles are blown bottles.
5, AS, ABS: AS transparency is better than ABS, and the toughness is better.
6, can be customized color, usually do primary color matte and magnetic white, or add pearl powder effect, the same color masterbatch with the bottle and cover, but sometimes because the material used for the bottle and cover is not the same, the color is somewhat difference.
7, silk screen has ordinary ink and UV ink, UV ink effect is good, shiny and three-dimensional sense, in the production should first confirm the color, the screen printing effect of different materials will be different.
8, bronzing, hot silver and other processing technology and printing gold powder, silver powder effect is different, hard material and smooth surface is more suitable for hot stamping, hot silver, soft surface hot stamping effect is not good, easy to fall off, hot gold and silver luster Better than gold and silver.
9, silk screen film to the negative film, the graphic effect is ochre, the background color is transparent, hot stamping, hot silver process to produce a positive film, the graphic effect is transparent, the background color is ochre. The text and pattern ratio should not be too small or too thin, otherwise the effect will not be printed.
10, the bottle cap is generally equipped with internal gaskets, pull caps, inner plugs, very few with a small spoon or dropper, which is mainly considering its sealing and ease of use.
