Why are aluminum tubes popular in the beauty and personal care industry?

In the beauty and personal care industry, aluminum hoses have gradually become a friendly choice for many brands due to their excellent functionality, environmental friendliness and high-quality texture. Here we will help brands and buyers understand the cost-effective packaging solutions of aluminum tubes from three aspects: functional advantages, manufacturing processes and product structure design.

1. The main functions and advantages of aluminum tubes

Strong barrier properties：Aluminum naturally has good light-blocking and oxygen-blocking properties. The molecular structure of aluminum can block 99% of ultraviolet rays, oxygen and water vapor, effectively protecting active ingredients (such as VC, retinol) from oxidation and deterioration, extending the shelf life. It is particularly suitable for creams, gels, essences and other products that are easily affected by air.

Good extrudability：The hose has excellent elasticity and controllable resilience, which can accurately control the dosage and avoid waste by hanging on the wall. The natural antibacterial property of aluminum inhibits the growth of microorganisms. Its hygienic and safety advantages enhance the user experience. It is often used in high-concentration products such as eye cream, hand cream, hair dye, and repair cream.

Recyclable and environmentally friendly：Aluminum is a recyclable resource, which is in line with the global environmental protection trend and helps the brand build a green and sustainable image.

High-end texture：The aluminum surface can achieve a variety of effects such as matte, electroplating, anodizing, etc. The combination of metallic luster and matte/hot stamping technology can enhance the brand premium ability and is suitable for the visual presentation of high-end skin care products and beauty series.

2. Manufacturing process of aluminum tube

Aluminum tube production mainly goes through the following key steps:

Extrusion molding (Extrusion) squeezes the aluminum ingot into a seamless hose under high pressure to form a tube body with a solid overall structure. The length of the tube body is determined by the diameter of the aluminum sheet, and its length is determined by the thickness of the aluminum sheet.

Annealing (Annealing) heats and softens the aluminum tube to improve ductility and facilitate subsequent printing and bending.Surface treatment and printing can be achieved by anodizing, electrophoretic coating, silk screen printing, pad printing and other methods to achieve brand customization. Currently, spot color printing is used. After all colors are printed, the aluminum tube is dried at a furnace temperature of 160 degrees. Due to this unified drying method after printing, if multiple colors are superimposed during the printing process, it will become very difficult to follow up on the colors. Due to the innovation of surface printing technology, a technology called integrated coloring technology is to add 0.1-0.5% gold powder + surface modifier to the quenching liquid to directly form a gold oxide layer, replacing traditional electroplating and eliminating the anodizing process.

The filling and sealing process is heat-sealed or mechanically folded according to customer needs to ensure product sealing.

3. Highlights of aluminum tube structure design

The structure of the aluminum tube can be customized according to different product attributes, including:

Spiral bottle mouth and cap: suitable for different filling types and usage scenarios; the vertical cap can stand up to prevent pollution and is more suitable for facial mask brushes; the octagonal cap is anti-rolling and is more suitable for bathroom products; the magnetic cap can be operated with one hand and is more suitable for cleansers, hand creams and other products.

Controllable discharge port design: such as narrow mouth, anti-pollution metal head, suitable for fine care such as eye essence;

Aluminum-plastic composite structure: the inner layer can be optionally coated with polymer to improve the stability of the contents;

Multiple capacity options: standard packaging from 5 ml to 100 ml can be flexibly adjusted to test and retail needs according to user needs.

Conclusion:

Aluminum tubes are not just a form of packaging, they are a balance of functionality and aesthetics, and they also reflect the idea of environmental protection and sustainable development. For beauty and personal care brands that want to enhance their brand identity and focus on product stability and environmentally friendly packaging, aluminum tubes are a high-quality choice that cannot be ignored.

Can I Clean The Air Conditioner By Myself ?

Every summer, air conditioners have become the most used home appliances. Particularly the wall split-air conditioners. However, if we do not clean it for a long time, the air conditioner will be dirtier than a toilet. Dust, mold, bacteria...all blown out with the cold wind. Most of us want to clean but think it's troublesome. So whether or not we can clean it? And to clean it efficiently? Let's take a close look:

I. Why should we clean the air conditioner regularly?

Severe dust accumulation ➜ Slow cooling and increased power consumption.
Moldy filter ➜ Odor and unclean air.
Bacteria breeding ➜ Easily cause allergies, asthma, and other respiratory problems.

PET bottles become the favorite of the cleaning industry packaging?

In daily cleaning products such as shampoo, shower gel and conditioner, PET (polyethylene terephthalate) bottles stand out from many plastic products and become the main choice in the market due to their excellent transparency, outstanding physical properties, mature recycling system and flexible processing technology. This time we will introduce PET bottles as a plastic container from three aspects: functional advantages, processing technology and structural design innovation.

1. Functional advantages of PET bottles

PET bottles have several key advantages in the packaging of cleaning products:

Lightweight and shatterproof: PET is durable and not easy to break even if it falls in a humid environment such as the bathroom, ensuring safe use. Compared with glass bottles, it greatly reduces transportation costs and carbon dioxide emissions. It can effectively resist impact during transportation, storage and use, and reduce the risk of breakage and leakage.

High transparency: PET bottles are clear and bright with good gloss, which can intuitively display the texture and color of the product and enhance the product's appeal on the shelf.

Strong chemical resistance: Suitable for shampoos and shower gels containing surfactants, essential oils and other ingredients.

Environmentally friendly and recyclable: In line with the trend of sustainable packaging, it can be recycled to reduce the impact on the environment.

Strong stability: The bottle is not easy to deform, ensuring that the appearance of the bottle remains consistent. PET bottles can be lightweight while ensuring strength, and also bring convenience and comfortable soft touch to consumers for daily holding and squeezing. Effectively resist collisions during transportation, storage and use, and reduce the risk of damage and leakage.

2. Manufacturing process of PET bottles

There are two main processes for forming PET bottles: one-step and two-step. The choice depends on factors such as cost, efficiency, and order size.

2.1Basic process: one-step vs two-step

Single-Stage: The three core processes of Injection Molding -> Heating and Temperature Control -> Stretch Blow Molding are completed continuously on the same dedicated equipment.

Advantages: compact process, high degree of automation, fast production speed, high energy utilization efficiency, and reduced risk of bottle embryo contamination. Disadvantages: high equipment investment cost and relatively low flexibility (suitable for large quantities of single bottle types). Applicable to: large-scale production of main product packaging of large-scale cleaning brands.

Two-Stage: First, the PET raw material is injection molded into a preform, and the preform is stored or transported after cooling. When necessary, the preform is reheated and stretch blow molded.

Advantages: Relatively low equipment investment (can be invested in steps), high flexibility (different preforms can be switched to produce different bottles at any time according to demand), convenient centralized production of preforms and decentralized blowing (such as close to the filling plant). Disadvantages: The overall energy consumption is slightly higher than the one-step method, the production cycle is slightly longer, and there are management costs for the storage and transportation of preforms. Applicable: Scenarios where small and medium-sized batches are produced, multiple varieties of bottles, and the supply chain needs to be decentralized.

2. 2Bottle embryo design

The PET raw material is heated and injected into the mold to obtain a preformed bottle embryo. The bottle embryo is the core intermediate in the manufacture of PET bottles. Its design (weight, wall thickness distribution, neck size) directly determines the performance (such as strength, capacity, hardness) and appearance of the final bottle. The bottleneck size is determined during the injection molding stage and no changes are made in subsequent operations.

2.3Stretch blow molding

After heating the preform to the appropriate temperature, it is stretched longitudinally, and high-pressure air is injected into the preform to expand it laterally and cling to the inner wall of the mold. After injection molding, the PET bottle is cooled, taken out, and enters the inspection and packaging stage. Stretch blow molding are key steps to give the bottle its final shape and performance.

2.4 Functional coating technology

Inner wall hydrophobic coating: To solve the problem of sticky cleaning products (such as lotions and conditioners) hanging on the wall, an inorganic silica hydrophobic coating can be applied to the inner wall of the PET bottle.

External surface treatment: such as matte frosting (to enhance texture), anti-scratch coating, etc.

3. Structural design features of PET bottles

The structure of PET bottles is usually personalized according to the use function and filling requirements.

Bottle mouth thread design: adapt to pump head, push cap or flip cap to improve sealing and user experience.

Thickness and thinness of bottle body: reasonably control the wall thickness distribution, enhance pressure resistance and appearance beauty.

Anti-slip bottle bottom: improve placement stability through thickening or anti-slip texture treatment.

Supports multiple printing methods: such as silk screen printing, thermal transfer, label attachment, etc., to meet the needs of personalized brand customization.

Diversified bottle design: unique shapes (such as curves, edges, and bionic forms) are designed through precision molds.

Large-capacity handle design: snap-in handles and adhesive handles are important for improving portability. The bottle body has no seams and is 100% recyclable.

Labels and decorations: In-mold labeling, wash labels, and screen printing are all appearance decorations that are friendly to recycling.

In today's rapidly developing cleaning industry, PET bottles have an excellent balance of function, cost, beauty and sustainability.

As a professional cleaning PET bottle supplier, we provide one-stop services from bottle design, mold development to OEM customization to meet your diverse needs from standard models to high-end customization.

Will It Damage The Air Conditioner If It Is Not Turned On For A Long Time?

A lot of users think that leaving the air conditioner unused for months or even one year will not cause any problems. However, not using air conditioners for a long time will not only influence the cooling effect but also damage the machine itself in many aspects. This article will clarify the reasons and come up with some maintenance tips.

I. Potential problems

1. Compressor aging, poor lubrication

The compressor is the heart of the air conditioner; not using it for a long time will lead to lubricating oil sedimentation and oil film tearing. It will add more friction when starting the air compressor and damage the spare parts inside, even burning the compressor.

2. Parts getting damp and rusty inside

Both the indoor and outdoor units include metal parts. If not used for a long time without moisture prevention measures, the PCB board and fan motor will get damp and age due to the humidity in the air.

3. Dusty filter with breeding bacteria

If there is no regular cleaning, the filter will accumulate dust, pollen, and even mold. Not using it for a long time, the air conditioner will be the warm bed for the bacteria. Dirty air will be blown into the room when staring.

4. Unseen refrigerant leakage

If the air conditioning system has a slight leakage of the refrigerant and is not used for a long time, then it will not be detected timely. Once we go back to use it and find it does not cool, the compressor is already damaged.

II. Suggestions to maintain an air conditioner without using it for a long time

Shorten operation each month

- It is recommended to turn on the air conditioner for 10-15 minutes every month, even in the non-using seasons. It keeps the compressor, fan, and electric circuit in an active condition.

Completely clean the filter and panel

- Before turning the air conditioner off, it is necessary to clean the air filter and the machine itself to avoid accumulation of the dust and bacteria.

Keep a dry environment

- It is suggested to use dehumidify mode for a period before turning off the AC units to keep the machine dry inside, particularly during the rainy season and in humid areas.

Cover the outdoor unit well

- If the air conditioner is not in use and will be exposed to direct sunlight or rain for a long time, we can use a mask or canvas to cover and protect the outdoor unit and avoid aging.

air conditioner maintenance

III. Tips before reactivating the air conditioner

Clean or change the filter.
Check the battery and the power supply.
Supply the power for 2-3 minutes before starting, avoiding voltage surge.
If poor cooling or a strange smell occurs, please contact the professional team for help.

Air conditioners are not meant to be left idle. Not turning them on for long periods of time will damage the machine. Only if we turn it on regularly, clean the filter, take moisture-proof and dust-proof measures, and take such easy steps can we extend the lifespan of air conditioners and ensure safety. The regular maintenance should be a concern, particularly in South China and other tropical countries.
