latest trend of cosmetic tube packaging manufacturing

2021-10-18

Whether for cosmetic tube suppliers, makeup brands or consumers, cosmetic tube packaging is convenient, environmentally friendly, and cost-saving, making it the best choice for the cosmetics and care products market.

Compared with other wholesale cosmetic packaging materials from other cosmetic tube manufacturers, cosmetic plastic packaging tube is very flexible and suitable for a variety of decorations, and at the same time it can be produced more quickly than other materials. In addition to choosing the color favored by the makeup brand, the packaging cosmetic tube also has a metallic texture and mature printing technology powered by cosmetic tube manufacturers. The separation of the cover cosmetic tube allows consumers to have more flexibility in squeezing the product i.e., squeeze cosmetic tube. It can be said that the packaging cosmetic tube itself is the advertisement of the makeup brand and product.

With the expansion of more automatic filling technologies, the cost of filling has also been greatly reduced, thus bringing more profit margins to the makeup brand. Modern technology of manufacturing bulk cosmetic tubes has also given more innovative designs to the cosmetic tube, such as the extended nozzle tip to make the users easier to apply makeup. In addition, more products prefer to use tin foil to seal and use novel colors to create a metallic texture.

For those formula product makeup brands that are sensitive to air and light, airless cosmetic tube packaging is another important reason why more and more cosmetics and care makeup brands love skin care tube packaging.

Airless cosmetic tube from plastic cosmetic tube suppliers is one of the makeup brand's favorite choices because it has great packaging advantages, especially preventing air from flowing back into the tube packaging, thereby damaging and contaminating the product formula. Mainly cosmetic tube manufacturers provide standard airless central pumping product packaging, which can guarantee customers the safe and effective packaging of formulas that require barrier protection technology which provides up to five layers of protective barriers between the product formulation and the outside world, and provides four different sealing film materials, such as ABL, CAL, VMPE and HAL materials, each of which can ensure functionality and satisfy consumers Aesthetic needs.

The aluminum-plastic composite cosmetic tube or pure aluminum cosmetic tube has become very popular in recent years, mainly because it is processed into a sheet with aluminum foil and plastic film through a co-extrusion composite process, and then processed into a cosmetic tube packaging container by a special tube machine in a cosmetic tube factory, which is especially suitable for hygiene and barrier Cosmetic packaging with high performance requirements.

With the continuous development of science and technology, the thickness of the aluminum foil barrier layer in the aluminum-plastic composite tube has been reduced from the original 40μm to 12μm, or even 9μm. Aluminum foil has excellent barrier properties such as light barrier, oxygen barrier, and water barrier. On the one hand, it can prevent foreign substances from entering the interior of the cosmetics to cause oxidative deterioration of the cosmetics. On the other hand, it can prevent the moisture or glycerin in the cosmetics from passing through the cosmetic tube. Spreading to the outside world, thereby effectively ensures the quality of cosmetics. More importantly, through the adjustment of structure and process, cosmetic packaging is easier to achieve high-brightness effect, especially suitable for cosmetic tube packaging.

Multi-dimensional decoration advantages

The continuous development of modern decoration technology of cosmetic tube manufacturers has brought more choices to makeup brands. Both popular makeup brands and high-end makeup brands prefer to choose tube packaging to increase the charm of their products.

With the continuous updating of cosmetic tube printing technology, the lithographic printing equipment has also been continuously developed with higher accuracy. The improvement of offset printing, silk screen printing and thermal printing technology has brought a new situation in cosmetics and care product wholesale packaging printing.

The background pattern and color tone on the cosmetic tube packaging also adopt high resolution and high precision to match the digital electroplating technology in the bulk cosmetic tube production process launched by cosmetic tube manufacturers. The application of the electrochemical aluminum hot stamping process to the composite sheet can also make the processed cosmetic composite tube have a bright appearance effect, and make the surface of the composite sheet show a super bright luster, which can stimulate consumers' desire to buy.

But at present, this technology still has some problems that continue to be solved. The adhesion of the hot stamping foil on the surface of the composite sheet is not high, and it is easy to fall off, so the hot stamping process is very demanding. At the same time, the relatively high price also makes many makeup brands avoid the use of this material, so it is more commonly used in high-end cosmetic composite tubes by cosmetic tube manufacturers.

With the continuous improvement of modern packaging technology and related industry technology, the development of wholesale cosmetic tubes packaging is changing with each passing day. New cosmetic tube packaging forms are also rich and colorful, one after another, and there are more choices, such as some cosmetic tubes manufacturers even come up with kraft paper cosmetic tubes, sugarcane cosmetic tubes.

In the future, wholesale cosmetic packaging should be both protective, functional and decorative in order to gain a place in the fiercely competitive market. Tube cosmetic packaging requires special new structures, new materials and new processes to occupy new markets. At the same time, economical and easy-to-recyclable sheets are used to the greatest extent, so as to meet the functional, decorative, environmental and cost requirements of cosmetic packaging.

1. Material selection　

The quality of the material for cosmetic tube manufacturing is the key to ensuring the quality of the makeup tube, and it will directly affect the processing and final use of the cosmetic tube. Plastic cosmetic tube materials include polyethylene PE (for tube body and tube cap), polypropylene PP (tube cover), color masterbatch, barrier resin, printing ink, varnish, etc. Therefore, the selection of any material will directly affect the quality of the tube. However, the choice of materials also depends on factors such as hygiene requirements, barrier properties (requirements for blocking oxygen, water vapor, and fragrance retention), chemical resistance and other factors.

2.The choice of cosmetic tube material:

A. Hygiene of materials

First of all, the materials used must meet the relevant sanitary standards, and harmful substances such as heavy metals and fluorescent agents should be controlled within the specified range. For example, polyethylene (PE) and polypropylene (PP) used in manufacturing cosmetic tubes exported to the United States must meet the US Food and Drug Administration (FDA) standard.

B. The barrier properties of the material.

If the contents of the daily cosmetic company's cosmetic tube packaging are products that are particularly sensitive to oxygen (such as some whitening cosmetics) or whose fragrance is very volatile (such as essential oils or some fats, acids, salts and other corrosive chemicals), then Five-layer co-extrusion tube should be used. Because the oxygen transmission rate of a five-layer co-extruded tube (polyethylene/bonding resin/EVOH/bonding resin/polyethylene) is 0.2 to 1.2 units, while the oxygen transmission rate of an ordinary polyethylene single-layer cosmetic tube.

The rate is 150 to 300 units. In a certain period of time, the weight loss rate test of the co-extruded cosmetic tube containing ethanol is dozens of times lower than that of the single-layer makeup tube. In addition, EVOH is an ethylene-vinyl alcohol copolymer with excellent barrier properties and fragrance retention (the thickness is 15-20 microns is the most ideal) double-layer tube: using high-density HDPE and LDPE low-density PE material, The cosmetic tube pumping method that matches the ratio of, achieves a uniform mixing effect by high-speed rotation. This method can appropriately adjust the softness and hardness of the cosmetic tube. Compared with the single-layer cosmetic tube, the cosmetic tube body is thicker and has better corrosion resistance. With its high barrier properties and lower oxygen transmission rate, it is adopted by the majority of cosmetics manufacturers.

The stiffness of the cosmetic tube manufacturing material that suppliers offer

Daily chemical companies have different requirements for cosmetic tube stiffness, so how to obtain the desired stiffness? The polyethylene commonly used in cosmetic tubes is mainly low-density polyethylene, high-density polyethylene, and linear low-density polyethylene. Among them, the stiffness of high-density polyethylene is better than that of low-density polyethylene, so the desired stiffness can be achieved by adjusting the ratio of high-density polyethylene/low-density polyethylene.

C. The chemical resistance of the material.

High density polyethylene lower density polyethylene has better chemical resistance.

D. the weather resistance of the material. To control the short-term or long-term performance of the cosmetic tube, it is necessary for cosmetic tube manufacturers to consider factors such as appearance, pressure/drop performance, sealing strength, environmental stress crack resistance (ESCR value), fragrance and active ingredient loss.

2. The choice of color masterbatch

Color masters play an important role in tube quality control of bulk cosmetic tube manufacturing . Therefore, when choosing a color masterbatch, user companies should consider whether it has good dispersibility, filtration and thermal stability, weather resistance and product resistance. Among them, the product resistance of the color masterbatch is particularly important during the use of the tube. If the color masterbatch is incompatible with the product installed, the color of the color masterbatch will migrate to the product, and the consequences will be very serious. Therefore, daily chemical companies should test the stability of new products and tubes (accelerated test under specified conditions).

3. Types of varnish and their characteristics

The varnish used in cosmetic tube is divided into ultraviolet UV type and thermal drying type, which can be divided into bright and matte in appearance. Varnish not only provides beautiful visual effects of cosmetic tube, but also protects the contents, and has a certain barrier effect on oxygen, water vapor, and fragrance. Generally speaking, hot-drying varnishes have good adhesion to subsequent bronzing and silk screen printing, while ultraviolet UV varnishes have better gloss. Daily chemical companies can choose appropriate varnish according to the characteristics of their products. In addition, the cured varnish should have good adhesion, and the surface should be smooth and free of pitting, bend-resistant, abrasion-resistant, corrosion-resistant, and odorless, and there should be no discoloration during storage.

4. Requirements for cosmetic tube body/tube cap

1) The surface of the cosmetic tube body should be smooth, free of stripes, scratches, strains, and shrinkage. The makeup tube body should be straight and not bent. The tube wall thickness should be uniform. The cosmetic tube wall thickness, tube length and diameter tolerances should be within the specified range.

2) The cosmetic tube cap and the tube body of the cosmetic tube should be firmly connected, and the wiring should be neat and beautiful, with uniform width, and the cosmetic tube cap should not be skewed after being connected.

3) The cosmetic tube cap and the cosmetic tube cover should cooperate well, screw in and out smoothly, and there is no slippage phenomenon within the specified torque range, and there is no water or air leakage between the cosmetic tube and the cover.

5. Printing requirements

Cosmetic tube processing usually uses dry offset printing (OFFSET), most of the ink used is UV drying, which usually requires strong ink adhesion and resistance to discoloration. The printing color should be within the specified range of shades, the overprint position should be accurate, the deviation should be within 0.2mm, and the font should be complete and clear.

The requirements of plastic cosmetic tube cover

Plastic caps are usually made of polypropylene (PP) by injection molding. High-quality plastic cosmetic tube caps should have no obvious shrinkage lines and draping during manufacturing. The parting line should be smooth, the size of cosmetic tube should be accurate, and it should be smoothly matched with the makeup tube cap, and it will not be brittle during normal use. Structural damage such as cracks. For example, when the opening force is within the range, the flip cover should withstand more than 300 folding times without breaking.
