⒈The raw materials of plastic bottles are usually PP, PE, K material, AS, ABS, acrylic, PET, etc.
⒉It is 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.
⒊PET 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 lined with the inner liner. The filling is not too full. Avoid the paste from entering the liner and the acrylic bottle. There is a crack, and the packaging needs to be higher when transported. It looks particularly noticeable after being scratched, has high permeability, and has a thick upper wall, but the price is appropriately expensive.
⒌AS, ABS: AS transparency is better than ABS, and the tolerance is better.
⒍Mould development cost: The blowing mold is 1,500 yuan to 4,000 yuan, and the injection mold is 8,000 yuan to 20,000 yuan. The stainless steel material for the mold is more expensive than the alloy material. However, after use, the mold is a few at a time. See The output needs, such as larger output, can choose one out of four or one out of six molds, customers can decide.
⒎The 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 pearl powder is added. Although the bottle and the cap are matched with the same masterbatch, sometimes because the bottle and cap are used The raw materials are different, and the colors shown are somewhat different.
⒏Silk screen printing has common inks and UV inks, UV inks have a good effect, gloss and three-dimensional sense, should be printed before the production to recognize the color, the screen printing function will be different in different raw materials.
⒐The 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 soft appearance of hot stamping is not good enough, easy to fall, and the gloss of hot stamping silver The degree is better than printing gold and silver.
⒑Silk film should produce a negative film, with black and white as the background, and the background color should be bright. Hot stamping and silver foil technology should produce a positive film with the black and white as the 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 cycle. The silk-screen cylindrical bottles are used for single-color calculation, and the flat or special-shaped bottles are calculated according to two-color or multi-color.
