China makeup packaging at Hoaxin plastic

Since entering the market, plastic bottles like Skin Care Bottles have been widely used by distributors and consumers because of their features of light weight, easy to carry, no fear of falling, and resistance to acids and alkalis. Therefore, plastic bottles have rapidly taken root in just a few decades. Circles. Until now, plastic bottles have become an important part of life. Drinks, food, pickles, and honey have been covered by the plastic bottle industry, and even agricultural, animal, and medical packaging have gradually been monopolized by plastic bottles. But do you know how plastic Skin Care Bottles are made? Plastic bottles are part of the rubber and plastics industry. No matter what kind of plastic bottles, they are molded. Plastic bottle molding process is phenolic resin, urea formaldehyde resin, unsaturated polyester resin and other polymers made of plastic products process. The plastic bottle processing methods include compression molding, extrusion molding, injection molding, blow molding, calendering, and the like. Next we will give you a detailed description of its processing methods.
Plastic bottle processing method
1. Compression molding is also called molding in the industry. It is the first step in the plastic bottle processing process for forming thermosetting plastics such as phenolic resin, urea formaldehyde resin and unsaturated polyester resin.
2. Extruded extrusion, also known as extrusion molding, is a method of continuously heating the heated resin through a die and extruding the desired shape using an extruder. It has the advantages of being able to extrude various shapes of products, has high production efficiency, can be automated and continuous production; the disadvantage is that thermosetting plastics can not be widely used this method of processing, product size is prone to bias.
3, injection molding can also be called injection molding. Injection molding is a method in which an injection molding machine is used to inject a thermoplastic melt into a mold under high pressure to obtain a product by cooling and solidifying the product. The advantages of injection molding are high production speed, high efficiency, automation of operation, and ability to form parts with complex shapes, which are particularly suitable for mass production. The disadvantage is the high cost of equipment and molds, and the injection molding machine is not easy to clean.
4, blowing blow molding is also called hollow blow molding. A method of inflating a hot resin parison closed in a mold into a hollow product is primarily a method of compressing air, and blow molding includes blown film and blown hollow products. The blow molding method is mainly used to produce film products, various bottles, barrels, pots and the like.
5, rolling calendering is the resin and various additives after the intended treatment through the calender after the two or more turns of the opposite calender roll processing into a film or sheet, and then peeled off from the calender roll, and then by Cooling shaping a molding method. Calendering is the main method of forming polyvinyl chloride resin, and is the main method for manufacturing films, sheets, plates, artificial leather, floor tiles and other products.
6, foam molding In the foaming material by adding an appropriate foaming agent, so that the plastic process of microporous structure. The cell structure is divided into open cell foam and closed cell foam, which is determined by the manufacturing method.

Basic knowledge of cosmetic plastic bottles
First, on the plastic bottle Mainly made of polyethylene or polypropylene and other materials and added a variety of organic solvents. Plastic bottles are widely used with polyester (PET), polyethylene (PE) and polypropylene (PP) as raw materials. After the corresponding organic solvents are added, after high-temperature heating, they are blown, extruded, or injection molded through plastic molds. Plastic container. Mainly used for beverages, food, cosmetics and other liquid or solid disposable plastic packaging containers. Plastic bottles have features such as non-breakable, low cost, high transparency, and food-grade raw materials. The
Second, the main material of cosmetics plastic bottles Material is usually PP, PE, K material, AS, ABS, acrylic, PET and so on. PET material is an environmentally friendly material, with high barrier properties, light weight, non-shattering properties, chemical resistance, strong transparency, can be made of pearlescent, colored, magnetic white, transparent, widely used in the installation of gel water. Bottle neck is generally the standard 16 #, 18 #, 22 #, 24 # diameter, can be used with the pump head. AS, ABS: AS transparency is better than ABS, and toughness is better. Acrylic materials are injection molded bottles, which have poor chemical resistance. Generally, they cannot be filled with paste directly. They need to be filled with an inner baffle to prevent overfilling and prevent paste from entering between the liner and the acrylic bottle. Cracking, high packaging requirements during transportation, as a result of scratches look particularly obvious, high permeability, sensory upper wall thickness, but the price is quite expensive. The
Third, cosmetic plastic bottles category and process
1. It is usually used for injection molding of cream jars, Skin Care Bottles, stoppers, gaskets, pump heads and dust covers with thicker walls of cosmetic containers; PET blow-molding for two-step molding, tube blanks for injection molding, and finished product packaging. To blow the bottle. Others, such as thinner container walls, washing bottles for blowing. The
2, mold development costs: blowing mold for 1500 yuan -4000 yuan, injection mold for the 8000 - 20000 yuan range, the mold with stainless steel material is more expensive than the alloy material, but durable, the mold once out a few, see The demand for production volume, such as the production volume, can choose one or four out of six molds, customers can decide. The
3, the order volume is generally 3,000 - 10,000, can be customized colors, usually do primary color scrub and magnetic white-based, or add pearl powder effect, bottle and lid although the same color master, but sometimes due to the bottle and cover The material used is different and there are some differences in the colors. Silk screen printing with common ink and UV ink, UV ink is better, shiny and three-dimensional, in the production of the first version to confirm the color, the screen printing effect in different materials will be different. 4, hot stamping, hot silver and other processing technology and printed 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 shiny Degree is better than Indian gold and silver. The silkscreen film must be printed in shades, with a graphic effect of dusk, a background color of transparency, bronzing, hot silvering to produce a positive film, a graphic effect of transparency, and a background color of dusk. The proportion of text and patterns should not be too small or too fine, otherwise no effect can be printed. The
5, the cap is generally equipped with internal gaskets, pull cover, plug, very few with a spoon or dropper, which is mainly to consider its sealing and ease of use.
