2021-06-14

Wholesale cosmetics tube and custom cosmetic tube made by cosmetic tube manufacturer because of their lightweight are easy to carry, strong and durable, recyclable, easy to extrude, good processing performance and printing adaptability, etc., by a large number of cosmetics production brand love, bulk cosmetic tubes are widely used in skincare products and other cosmetics packaging.

In a previous post, professional wholesale cosmetic tube manufacturer and supplier, Lisson published a brief introduction to tube knowledge about the types, features, and techniques of the cosmetic tube, but was unable to provide more detailed information due to the limitations of the data collected. Unable to solve the problem, Lisson could not tolerate the article, so decided to hang a nail in the coffin and gather information about the cosmetic tube. As a top cosmetic tube manufacturer, Lisson put together in this article, Lisson cosmetic tube factory hopes to help you better understand all aspects of wholesale cosmetic tubes.

Wholesale cosmetics tubes and cosmetic plastic tube features currently, plastic cosmetic tube commonly used in cosmetic packaging mainly includes the aluminium-plastic cosmetic composite tube, plastic composite tube and plastic cosmetic co-extrusion tube, which can meet the needs of cosmetic packagings, such as hygiene, barrier and so on.

1. Aluminium plastic cosmetic composite tube is a kind of cosmetic packing container made by cosmetic tube manufacturers, which is made of aluminium foil and plastic film by coextrusion and then processed by a special cosmetic tube making machine. Aluminum-plastic composite tube is mainly used for packaging cosmetics with high requirements of hygiene and barrier, and its barrier layer is usually aluminium foil, and its barrier depends on the porosity of aluminium foil. With the development of technology, the thickness of the foil barrier layer in the aluminium-plastic composite cosmetic tube for cosmetic tube manufacturers has been reduced from 40 m to 12 m or even 9 M, which greatly saves resources. The wholesale cosmetic aluminium-plastic composite tube in the use process has the following advantages.

(1) high barrier, aluminium foil with light, oxygen and water resistance and other barrier properties, on the one hand, can prevent the invasion of external substances into the interior of cosmetics, cosmetics to prevent oxidation deterioration, it also prevents moisture or fragrance from escaping to the outside world via a tube, thus keeping the cosmetic tube factory in place.

(2) low cost. To achieve the same barrier performance, cosmetic aluminium-plastic composite tube than plastic cosmetic composite tube and plastic co-extrusion of the material used, low cost, more economical.

2. TUBE FOR WHOLESALE COSMETIC TUBE manufacturer and supplier, tubeFor wholesale cosmetic tube manufacturer and supplier, all plastic makeup composite tube is plastic composition, divided into two kinds of plastic non-barrier composite tube and plastic barrier composite tube. The plastic barrier-free composite tube is generally used for low-grade and fast-consuming cosmetic packaging, and plastic barrier-free composite tube is usually used for middle-grade and low-grade cosmetic packaging due to the side seam of the tube, the barrier layer can be a multi-layer composite material containing EVOH, PVDC, oxide coating PET, etc. The typical structure of a plastic cosmetic composite tube is PE/PE/EVOH/PE.

Wholesale Cosmetic Plastic Composite Tube has the following advantages:

1)environmental protection. Compared with the wholesale custom cosmetic aluminium-plastic composite tube, the plastic cosmetic composite tube adopts the economical and easy-to-recycle plastic sheet material, which can reduce the environmental pollution caused by the packaging waste.

(2) a variety of colours. According to the characteristics of cosmetics and different consumer needs, the plastic cosmetic composite tube can be made into different colours, such as colourless transparent, colour transparent, colour opaque, to give consumers a strong visual enjoyment. In particular, the transparent plastic cosmetic composite tube can clearly see the content of the colour state, such cosmetic tubes can give a strong visual impact, greatly promote consumer desire to buy.

(3) good resilience: Plastic composite tube is more resilient than an aluminium composite cosmetic tube, ensuring that after extrusion the tube returns to its original shape and maintains a sleek, regular appearance. This is crucial for cosmetic packaging.

3. Plastic Cosmetic co-extrusion Tube

Co-extrusion cosmetic plastic co-extrusion tube comes with co-extrusion technology using different properties from cosmetic tube suppliers, types of raw materials co-extrusion together, a moulding. Plastic cosmetic co-extrusion tube is divided into single-layer extrusion tube and multi-layer co-extrusion makeup tube, the former is mainly used for the packaging of fast-wearing cosmetics (such as hand cream) which requires high appearance and low performance, the latter is mainly used for high-grade cosmetics packaging.

The main advantages of plastic co-extrusion tube are as follows:

(1) because there is no edge seal, the appearance of cosmetic tube is better than the composite cosmetic tube, which is necessary for high-grade cosmetic packaging.

(2) various shapes of extrusion cosmetic tube, such as oval and square, can be produced according to the different extrusion die ports to meet the needs of different consumers.

4. Among Cosmetic Tube Manufacturers, Lisson cosmetic tube factory tells plastic tubes for cosmetic packaging -their shortcomings.

(1) aluminium-plastic cosmetic composite tube has many disadvantages, such as invisible content, poor environmental protection, poor resilience, lower composite strength than the all-plastic composite cosmetic tube, easy delamination, etc.

(2) the barrier property of plastic composite tube mainly depends on the type and thickness of the barrier layer material. Take the plastic composite tube with EVOH as the barrier layer material as an example, to achieve the same barrier property and stiffness, the cost is about 20% to 30% higher than that of the aluminium-plastic cosmetic composite tube. This will be the main factor limiting the total substitution of a plastic cosmetic composite tube for an aluminium-plastic cosmetic composite tube in the near future.

(3) the production and processing technology of Plastic co-extrusion cosmetic tube is usually pre-made tube and then printed by cosmetic tube manufacturers, which is inefficient, complicated for the printing process.

Second, the advantages of plastic tubes commonly used in cosmetic packaging

The plastic tube is hygienic and convenient to use, and the surface is bright and beautiful. Therefore, it has been widely used in the packaging of cream cosmetics, such as facial cleanser, hair conditioner, hair dye, toothpaste and other products in the cosmetics industry, as well as in the pharmaceutical industry. Packaging of creams and ointments for external use medicines.

The cosmetic plastic tube packaging is economical, convenient and easy to carry. Even with high-strength squeezing, it can still be restored to its original shape and maintain a good appearance. Data show that 60%~70% of tubes are used in the cosmetics industry, 10%~15% of tubes are used in the pharmaceutical industry, and about 5% are used in the food industry. Therefore, how to better realize the design concept of the product through tube packaging, strengthen the decorative effect of tube packaging, and attract consumers' attention more quickly and fit the brand temperament has become an important topic for end-users to think about.

3. Product structure of cosmetic plastic tube packaging

The main part of the plastic tube includes a tube shoulder, a tube (tube body) and a tube tail. The tube part is often decorated by direct printing or self-adhesive labels to carry text or pattern information and enhance the value of product packaging.

At present, the decoration of cosmetic tubes is mainly realized through direct printing and self-adhesive labels. Among them, direct printing includes screen printing and offset printing. Compared with direct printing, the advantages of self-adhesive labels include printing diversity and stability: the traditional extrusion tube process of making tubes and then printing usually uses offset printing and screen printing, while self-adhesive printing can use letterpress, Diversified combined printing processes such as flexographic printing, offset printing, silkscreen, hot stamping, etc., make the performance of difficult colours more stable and excellent.

Fourth, the reasonable choice of the wholesale plastic cosmetic tube from plastic cosmetic tube manufacturers

In the cosmetics industry, packaging quality is the second life of products. According to the characteristics of cosmetics and sales situation and other factors, choosing a suitable plastic tube as packaging can make cosmetics more attractive under the high-quality packaging.

1. Hygiene and safety

Cosmetics are in direct contact with the human body, which imposes high hygiene and safety requirements on their packaging. For plastic tubes, the safety of raw materials (raw particles must comply with relevant laws and regulations, such as FDA, SGS certification, etc.), production process, production environment, etc. should be controlled to ensure the hygienic safety of the cosmetics inside.

2. Protective

Packaging materials should have sufficient mechanical strength, a certain degree of barrier properties, chemical resistance, weather resistance, etc., to prevent cosmetics from causing quality problems during filling, storage and transportation.

(1) Mechanical properties. The main function of cosmetic packaging is to use its mechanical properties to ensure that the contents are not damaged. The mechanical properties of the plastic tube for cosmetic packagings, such as compression resistance, impact resistance, and bending strength, are mainly determined by the nature of the cosmetic packaging product, packaging machinery, and storage and transportation requirements. Generally speaking, plastic cosmetic tubes must have a certain degree of stiffness to ensure that the overall shape of the product is intact; at the same time, they also need to have good resilience to ensure that they can return to their original shape after being squeezed. However, under the same material composition and the same thickness, stiffness and resilience are a pair of contradictions. Only by taking both into account can we meet customer needs.

(2) Barrier performance. Commonly used barrier materials for plastic soft for cosmetic packaging include aluminium foil, EVOH, oxide-coated PET and nylon, etc. The barrier properties vary depending on the selected material and thickness. For example, aluminium foil has high barrier properties. When the thickness of the aluminium foil is above 25μm, its barrier performance can reach 100%; the barrier property of EVOH to oxygen is proportional to its thickness, and the oxygen permeability of 15μm thick EVOH is about 0.3~0.4cc/m2 ·24h (macon detection method); the oxygen transmission rate of PET with oxide coating is generally 0.2～1.0cc/m2·24h (mocon detection method). Therefore, materials with different barrier properties should be selected according to the requirements of the packaged cosmetics. In addition, the interaction between fragrance and packaging materials should also be considered. For example, polyolefin materials absorb essential oils. At this time, a protective coating can be added between the aluminium foil and the polyolefin materials.

(3) Chemical resistance and weather resistance. The material selected for the plastic tube for cosmetic packaging should have resistance to chemical corrosion of the contents, including oil resistance, grease resistance, acid resistance, etc. The matrix resin can be optimized according to actual conditions and needs to meet the requirements of use, such as HDPE LDPE has better chemical resistance.

The weather resistance of the plastic tube is related to the temperature resistance, dimensional stability, environmental stress cracking resistance and other factors of the material used. Only by ensuring the short-term or long-term performance of the plastic tube can the quality and safety of cosmetics be guaranteed. For example, some cosmetics are suitable for use in the cold winter. If the plastic tube uses conventional materials such as PP, a series of problems such as failure in the drop test and tube burst may occur. This is because the glass transition temperature of PP is about -10°C. It is brittle and fragile at low temperature. At this time, it is necessary to adjust the formula structure of the plastic tube and use toughening materials to improve the impact strength of the plastic cosmetic tube.

3. Operability

In order to facilitate printing and packaging operations and cosmetic tube manufacturers to adapt to mechanized operations, plastic tubes for cosmetic packaging should have good printability, heat-sealing performance, and packaging machine suitability.

(1) Printability. From a printing point of view, aluminium-plastic and all-plastic composite tubes have more advantages than plastic co-extrusion tubes. Because the aluminium-plastic and all-plastic composite tubes are made of different materials through the extrusion process, the tube is made after the slitting and printing process, or the film after printing is passed through the extrusion and slitting process. Re-manufacturing the tube; while the plastic co-extrusion tube is first manufactured and then printed, which will inevitably lead to the complexity of the printing process.

(2) Heat sealing performance. The heat-seal performance includes two indexes: the initiation temperature and the heat-seal strength. Especially for some temperature-sensitive cosmetics, it is required that the temperature of the tube tail welding and sealing should not be too high. At this time, some low-temperature heat-sealing materials can be used for the heat cover to ensure that the welding and sealing will not affect the quality of the cosmetics at low temperatures. When filling cosmetics, the contents may contaminate the seal. Plastic tubes made of general materials cannot be sealed well. However, if the thermal cover is made of anti-pollution materials, this problem can be effectively solved.

4. Economy

Among aluminium-plastic cosmetic composite tubes, aluminium foil has the highest unit price, and cosmetic tube manufacturers can effectively control the cost of the cosmetic tube by controlling the thickness of aluminium foil. Therefore, under the premise of ensuring good product performance, using thinner aluminium foil, reducing losses in the production process, and using simplified packaging as much as possible can reduce the cost of aluminium-plastic makeup composite tubes.

At present, the cost of all-plastic composite tubes is relatively high. Without affecting various properties, reducing the thickness is also one of its future development directions. As a result, materials with high stiffness (such as PP, etc.) will be increasingly used in all-plastic composite tubes.

In order to reduce the printing cost of the plastic co-extruded cosmetic tube and take advantage of its appearance (no edge seal), a new cosmetic tube structure has been formed. The structure is to cover the printed composite tube with a transparent plastic co-extrusion tube through a special process so that the printed pattern inside is presented in front of consumers while maintaining the excellent feel of the plastic co-extrusion tube.

V. Prospects for future development trends: wholesale cosmetic tube and custom cosmetic tube

In recent years, more and more cosmetics manufacturers have begun to pay attention to environmental protection issues, and green packaging will become a trend. At present, the aluminium-plastic composite tube is still the main packaging material for high barrier products, which consumes a lot of resources and is very difficult to recycle. Replacing aluminium foil with barrier materials such as EVOH and SiOx coating films can not only achieve high barrier properties, but also can be recycled, but its high cost limits its wide use. On the other hand, the development and application of degradable plastics have alleviated environmental problems to a certain extent. The NatureWorks polymer produced by Lisson wholesale cosmetic tubes is a kind of polylactic acid resin, which can be used to process all kinds of plastics and packaging.

Biodegradability:

At the same time, multi-layer composite cosmetic tubes with protective, functional and decorative properties will seize more markets in the future. Multi-layer co-extrusion cosmetic tubes will gradually replace single-layer co-extrusion tubes to protect cosmetics. Sex is further enhanced. In addition, the use of advanced technology to minimize the visibility of the plastic tube joints and make the plastic tube look more beautiful will also be one of the development trends in the future.
