⒈ The raw materials of plastic bottles are usually PP, PE, K material, AS, ABS, acrylic, PET, etc.

⒉ Usually used for injection molding of thick cream bottles, bottle caps, stoppers, gaskets, pump heads, and dust covers for cosmetics containers; PET blow molding is two-step molding, tube blanks are injection molding, and product packaging is Blow the bottle. Others such as emulsion bottles and scrub bottles with thin walls are blown bottles.

⒊ PET materials are environmentally friendly materials, with high isolation, light weight, non-fragile characteristics, 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 usually the standard 16#, 18#, 22#, 24# caliber, which can be matched with the pump head.

⒋The raw material of acrylic is injection bottle, which has poor chemical resistance. Usually, it can not be directly filled with paste. It needs to be insulated with the liner. The filling is not easy to be too full. Avoid the paste from entering the liner and the acrylic bottle. There is a crack, and the packaging needs to be higher for transportation. Because it looks particularly noticeable after being scratched, it has high permeability and a thick upper wall, but the price is appropriately expensive.

⒌ AS, ABS: AS transparency is better than ABS, and the tolerance is better.

⒍ Mold development cost: the blowing mold is 1500 yuan to 4000 yuan, the injection mold is 8000 yuan to 20,000 yuan, the stainless steel material for the mold is more expensive than the alloy material, but after use, the mold comes out a few, see The output needs, if the output is large, you can choose one out of four or one out of six molds, the customer can decide.

⒎ The order quantity is usually 3,000 to 10,000, and the color can be customized. Usually the primary color is frosted and magnetic white, or the effect of pearlescent powder is added. Although the bottle and the cap are matched with the same masterbatch, sometimes because the bottle and the cap are used The raw materials are different, and the colors shown are somewhat different.

⒏ Screen printing has the usual inks and UV inks. UV inks have a good effect, gloss and three-dimensional sense. When producing, you should first print the plate to recognize the color. The screen printing function will be different in different raw materials.

⒐ The processing technology of hot stamping and hot stamping is different from that of gold powder and silver powder. Hard materials and lubricating appearance are more suitable for hot stamping and hot stamping. The degree is better than printing gold and silver.

⒑ Screen printing film should produce negative film, black and white for graphics and text, background color is bright, bronzing, hot silver technology should produce positive film, bright for graphic and text, and black color for background. The share of words and pictures should not be too small or too thin, otherwise it will not work.

⒒ Bottle caps are usually equipped with inner gaskets, pull caps, inner plugs, and very few are equipped with small spoons or droppers. This is mainly to consider its sealing and ease of use.

⒓ The production cycle is relatively moderate, about 15 days. The silk-screen cylindrical bottles are used for single-color accounting, and the flat or special-shaped bottles are calculated for two-color or multi-color.
