1. The material of plastic bottles is usually PP, PE, K material, AS, ABS, acrylic, PET, etc.
2, usually used for cosmetic containers, thicker cream bottles, caps, stoppers, gaskets, pump heads, dust covers for injection molding; PET blowing bottles for two-step molding, tube blanks for injection molding, finished packaging For blowing bottles. Other emulsion bottles such as thinner containers and washing bottles are blown bottles.
3, PET materials are environmentally friendly materials, with high barrier properties, light weight, non-breaking characteristics, chemical resistance, strong transparency, can be made of 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.
4, 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.
5, AS, ABS: AS transparency is better than ABS, and the toughness is better.
6. Mold development cost: 1,500 yuan - 4,000 yuan for blowing molds, 8,000 yuan - 20,000 yuan for injection molds, stainless steel materials for molds are more expensive than alloy materials, but durable, molds come out several times, see The demand for production, such as the large production volume, can choose a mold that is four or one out of six, and the customer can decide at their own discretion.
7, the order quantity is generally 3,000 - 10,000, 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 due to the bottle and cover The materials used are different, and the colors displayed are somewhat different.
8, silk screen has ordinary ink and UV ink, UV ink effect is good, shiny and three-dimensional sense, in the production should first check the color of the plate, the silk screen effect will be different in different materials.
9, 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.
10, silk screen film to get a 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.
11, 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.
