The increasing use of plastic cosmetic tubes is related to the production process and recycling

2021-11-01

With the increasing use of plastic cosmetic tubes, cosmetic tube manufacturer in order to continuously meet the development requirements of injection molding products towards high integration, high-levelization, and high output, as well as to achieve the aggregation state, phase morphology, organization morphology and other aspects of the product materials. Control, to achieve the composite of heterogeneous materials for products, to maximize the characteristics of polymers, to achieve the purpose of high performance of products, injection molding technology has been greatly developed.

 

In terms of injection molding process, gas-assisted injection molding, structural foam molding, reaction injection molding, co-injection molding, push-pull molding, injection-compression molding, low pressure injection molding, alternating injection molding, melt core injection molding, dynamic pressure holding Injection molding has introduced key technologies such as in-mold reaction, foaming, vibration and gas-assisted. The cosmetic tube factory has enriched the content of traditional injection molding process, so that the flow characteristics of the plastic cosmetic tube, the mechanical properties of the product, and the appearance quality are all effectively controlled.


In terms of injection molding equipment, in addition to the improvement or enhancement of traditional injection molding equipment to adapt to the new injection cosmetic tube production process, there are also great improvements in injection molding auxiliary machinery automation, energy-saving injection molding machine technology and mold technology, and injection molding machines. For example, the all-electric injection molding machine is a very versatile injection molding machine, which is gradually being promoted at this stage.

 

It is of course imperative for Cosmetic tube manufacturer to adapt to this trend, and the specific manifestations are as follows:

 

1. The structural design of the Plastic cosmetic tube product is more humane and has advanced consciousness. Companies producing cosmetic tubes need to focus on market research, accurate analysis, and get the real consumer needs and development trends of consumers. In the production of cosmetic plastic cosmetic tubes, they must be "people-oriented" to meet people's needs. Cosmetic tube design Catering to the consumer psychology of consumers, cosmetic tube factory carries out targeted plastic cosmetic tube production and produces market-competitive high-quality cosmetic plastic cosmetic tubes, which enables wholesale cosmetic tube manufacturers to develop rapidly and steadily in the fierce market competition. 


2. Multi-layer co-extrusion blow molding technology. The plastic container produced by Cosmetic tube supplier using this technology can meet the needs of a novel and beautiful appearance while protecting the contents. It is a product that is co-extruded with different properties and types of plastics and formed at one time. The product has the advantages of various materials, which can meet the high barrier requirements of cosmetics and detergents, and all avoid the oxidation of cosmetics. At the same time, the factory undergoes different With the blending of materials, the appearance and visual effect of the product will present a clever and special feeling.

 

3. Design of cosmetic green packaging materials. Nowadays, cosmetics companies are beginning to pay attention to environmental protection issues. Of course, the packaging bottles they choose will also require their characteristics, considering whether the materials themselves are environmentally friendly and whether the materials can be recycled and reused. There are PCR cosmetic tube, aluminum plastic cosmetic tube, sugarcane plastic cosmetic tubes available.

 

4. The status of plastic cosmetic tube will remain hot. Plastic cosmetic containers have the characteristics of light weight, etc., and now the plastic production technology of cosmetic tube manufacturer can already meet the transparency requirements of glass, all of which can meet the different needs of different consumers in the market.

 

The thickness of each part of the product is different, the internal pressure of the mold is insufficient, the mold is not sufficiently cooled, and the deformation caused by the insufficient cooling time is related to the knowledge. In the process of producing the product, the dent is a defect that occurs frequently, and it is injected into the mold. The plastic shrinks in volume when it cools. The early cooling part, that is, the surface hardens first, and bubbles are generated inside. The so-called dent is that the slow cooling part has a conspicuous concave surface in the direction of the bubble shrinkage.


    When the Cream plastic cosmetic tubes were sent for recycling, they were all covered with caps. This is usually inappropriate. This is not because the plastic used to make plastic cream bottle caps cannot be recycled. Most types of plastic cosmetic tubes & bottles can be recycled. Its because the plastic used to make the plastic cosmetic tube cap and the plastic used to make the bottle body are usually not the same type, and if the two types of plastic are mixed together for recycling, it is equivalent to letting one type of plastic contaminate the other. , Thereby reducing its use value, or it takes manpower to separate the two during processing.

     

    Another reason for not recycling cosmetic tube caps is that when plastic cosmetic tubes are processed in the recycling center, PE caps may jam the machine. In addition, bottle caps may threaten the stability of recycling workers. Most of the recycled cream plastic cosmetic tubes are squashed and packaged before being shipped away. If the lid of the cream plastic cosmetic tube is tightly closed and the bottle body is not crushed, it may explode due to the expansion of the gas in the bottle when the temperature rises, causing injuries to workers.

    Therefore, it is actually a more responsible approach to remove and throw away the cap before recycling the plastic cosmetic tube. Some recycling centers may also accept the recycling of bottle caps, but the caps and bottle identity should also be opened.


    Plastic cosmetic tubes are difficult to meet the standards in terms of hygiene and quality. The reason why these secondary materials can prevail in the market lies in their extremely low prices. Compared with new materials, these substandard secondary materials are even less than half the price.

    Some plastic cosmetic tube manufacturers use or mix them with new materials in order to reduce costs. If these plastic cosmetic tubes are circulated to the packaging fields of food, medicine, etc., they will be more harmful to people if they come into direct contact with food and drugs. At the same time, he also created unfair competition for manufacturers who use new materials to produce plastic cosmetic tubes, and the production of these secondary materials often creates harsh environmental problems.

     

    For these secondary plastic cosmetic tubes, on the one hand, it is necessary to strictly punish the manufacturers of plastic cosmetics tubes, and it is more important to strictly supervise waste plastic processing enterprises, starting from the source, and resolutely banning enterprises that do not meet the standards.

     

    High isolation packaging. High-isolation packaging is the use of insulating materials to restrain gas and water vapor. Smell, light, etc. enter the package to guarantee the cosmetics's quality. The application of high insulation packaging is very extensive. The edge and corner part is the part where the parison is inflated and then touched, and the wall thickness of this part is small. Therefore, the edges and corners of the plastic cosmetic tube should be designed with rounded corners. Changing the surface shape of the plastic cosmetic tube, for example, the middle part of the plastic cosmetic tube is relatively thinner, and increasing the circumferential groove or rib on the surface of the plastic cosmetic tube can improve the rigidity and bending resistance of the plastic cosmetic tube. Longitudinal grooves or ribs can be used to offset, sag or deform the plastic cosmetic tube under long-term load.
