A few explanations about the common sense of the pump head of plastic packaging bottle for daily chemical products
⒈The raw materials of plastic bottles are usually PP, PE, K material, AS, ABS, acrylic, PET, etc.
⒉Cream bottles, bottle caps, stoppers, gaskets, pump heads, and dust covers are usually used for cosmetics with thicker walls. Injection molding; PET blow molding is two-step molding, tube embryo is injection molding, and the product packaging is Bottle blowing. Others, such as lotion bottles and scrubbing bottles with thin container walls, are blown bottles.
⒊ PET materials are environmentally friendly materials, with high insulation, light weight, non-breaking characteristics, chemical resistance, extremely transparent, can be made into pearlescent, colored, magnetic white, transparent, and widely used in gel water. The bottle mouth is usually the standard 16#, 18#, 22#, 24# caliber, which can be used with a pump head.
⒋Acrylic raw materials are injection-molded bottles, which have poor chemical resistance. Usually, pastes cannot be directly filled. They need to be isolated with an inner tank. The filling is not easy to be too full. Avoid the paste entering between the inner tank and the acrylic bottle. If cracks occur, the need for side-by-side packaging is higher because of scratches, which look particularly obvious, have high permeability, and the sensory upper wall is extraordinarily thick, but the quotation is moderately expensive.
⒌AS, ABS: AS has better transparency than ABS, and has better durability.
⒍Mould development costs: blowing molds are 1,500 yuan to 4,000 yuan, injection molds are 8,000 yuan to 20,000 yuan, molds using stainless steel materials are more expensive than alloy materials, but after use, several molds can be produced at a time. The demand for output, if the output is large, you can choose a mold with four or six molds, and the customer can decide by himself.
⒎The order quantity is usually 30,000 to 10,000, and the color can be customized. Usually the primary color is frosted and magnetic white, or pearl powder is added. Although the bottle and cap are matched with the same color master, sometimes because the bottle and cap are used The raw materials are different, and the colors displayed are somewhat different.
⒏ Screen printing has common inks and UV inks. UV inks have good effects, gloss and three-dimensionality. The color should be recognized first when printing. The effect of screen printing on different raw materials will be different.
⒐The processing technology of bronzing and silver bronzing is different from that of printing gold powder and silver powder. The hard material and lubricated surface are more suitable for bronzing and silver bronzing. The soft surface has poor bronzing effect, easy to fall, and the gloss of bronzing silver Degree is better than printing gold and silver.
⒑ The silk screen film should produce negative films, the graphic effect is black, the background color is transparent, the hot stamping and silver hot technology should produce positive films, the graphic effect is transparent, and the background color is black. The share of text and pictures should not be too small or too fine, otherwise the printing will not be effective.
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 because of its sealing and ease of use.
⒓ The production cycle is relatively moderate, about 15 days. The silk-screened cylindrical bottle is calculated in a single color, and the flat bottle or a special-shaped bottle is calculated in two or multiple colors.
