What physical tests does the tube packaging have to undergo?

1.Thickness measurement

The precise thickness of each layer of a tube is fundamental to its performance. This test uses a micrometer or specialized thickness gauge to measure the actual thickness of each layer (from the inner barrier film to the outer printed layer), typically at five to ten points throughout the tube. The goal is to ensure compliance with design specifications.

2.Sealing performance test

Heat Seal Strength (Tube End): Tube ends are sealed using heat during the manufacturing process. This test measures the force required to tear the seal. It ensures that the seal will not crack during extrusion, transportation, and storage. Standards generally require a minimum strength to ensure reliability.

Torque Test (Tube End to Cap): This test evaluates the tightness of the connection between the tube end and the cap. A torque meter measures the force required to unscrew or tighten the cap, ensuring it is neither too loose nor too tight. Typical ranges vary depending on product type—cosmetic tubes may require 0.5-1.5 Nm.Positive/Negative Pressure Test: To simulate extreme conditions, the tube is subjected to positive or negative pressure in the seal. This can identify micro-leakages in the seal that may be missed by standard visual inspection.

3.Barrier performance test

Barrier performance is crucial for products susceptible to external influences like oxygen and light.

Two key test types dominate this category:

Oxygen Transmission Rate (OTR): According to the standard, this test measures the amount of oxygen that passes through the tubing material over time. A low OTR is crucial for products like vitamin C serums or essential oils, as oxidation can reduce their effectiveness.

Water Vapor Transmission Rate (WVTR): According to the standard, this test quantifies the amount of moisture that migrates through the tubing. This is crucial for dry products (such as powdered skincare) or water-sensitive formulas, as excessive moisture can lead to clumping or microbial growth.

4.Mechanical strength testing

Compression resistance: This test simulates warehouse stacking, placing the hose under pressure for a week. This checks for deformation, collapse, or seal failure under sustained load.

Drop test: Tubes (empty and full) are dropped from various heights (e.g., 1 meter, 1.5 meters) and at various angles (vertical, horizontal, diagonal) to simulate an accidental drop. This test ensures there are no cracks, leaks, or cap detachments.

Flex resistance: The tube is repeatedly flexed, particularly at the shoulder (where the barrel meets the nozzle), until it breaks, typically over 10,000 cycles. This test assesses the durability of travel-sized hoses or products designed for portable use.

5.Extrusion performance testing

You know what? A user's experience with a product is largely tied to how easy it is to squeeze the stuff out and how clean the whole process is.Take those squeeze tests, for example. We use something called a texture analyzer to measure just how much force is needed to get the product out of the tube. The goal here is to make sure it's not a total nightmare to squeeze (because who wants to get all frustrated, right?). But at the same time, it shouldn't be so easy that you end up squirting out way more than you need.And it doesn't stop there. The testers also keep an eye out for issues like "rat tails." You know, those stringy bits that hang around after you've squeezed the tube? Or problems with uneven flow. These little things might seem minor, but they can lead to a whole lot of wasted product and just a generally crummy experience for the user.Now, when it comes to medicine tubes where you need to get the exact right dose every single time, things get even more serious. The consistency of how much comes out with each squeeze is checked super carefully.

Floor ceiling air conditioner purchase guide 5 key recommendations not to ignore！

In recent years, the floor ceiling air conditioner has been gradually favored by the market due to the characteristics of “multi-purpose and flexible installation,” but the adaptability of such products is also different under different space, floor height, and use requirements.

The following 5 suggestions will help you to be more targeted when purchasing a floor-ceiling air conditioner so that the equipment can really play a value.

Although the “dual-use” structure design is flexible, attention should be paid to the matching space.

1. The ceiling/floor dual-purpose machine can be designed horizontally and vertically and has strong adaptability, but it is not universal for all household structures.

2. Lifting is beautiful, low noise, and more suitable for high spaces; landing is suitable for the type of house with more construction restrictions.

3. It is recommended to clarify the spatial pattern and decoration plan of the home and then determine the main installation method; “dual-use” as an auxiliary option is more reasonable.

The direction of air supply affects the experience, which needs to be judged in combination with living habits.

1. Under the hoisting condition, the air supply angle of some floor-ceiling air conditioners is limited, and the air supply may be close to the top or deflected.

2. If there is no air guide design in the direction of air supply in the landing state, it is easy to cause direct blowing and affect comfort.

3. When purchasing, it is recommended to pay attention to the wind range of the product and the automatic swing wind function and select the air supply direction according to the furniture layout.

Installation flexibility is high, but the process standards can not be relaxed.

1. The hoisting mode needs to cooperate with the drainage slope design, sealing plate edge, and other processes, which has high technical requirements for the construction team.

2. The landing mode needs to pay attention to stability, anti-dumping design, and beautiful treatment of exposed pipelines.

3. No matter which way you choose, it is recommended to be operated by a team with experience in the installation of the floor-ceiling air conditioner to ensure both safety and beauty.

There are differences between noise and wind sensation, and the measured data have more reference value.

1. Lifting wind is soft and quiet, making it suitable for a bedroom or quiet space; however, it requires a specific height for the floor.

2. The floor wind feeling is strong, suitable for a living room or a ventilation demand, but you need to pay attention to close-range noise.

3. It is recommended to view the measured noise data under different installation methods provided by the manufacturer, which is better than just looking at the word “mute.”

Core performance priority and functional richness are not the focus of the purchase.

1. Some products are compatible with the “dual-use” structure and may compromise on temperature control accuracy or energy efficiency ratio.

2. It is recommended to give priority to its core performance, such as cooling capacity, energy efficiency ratio, and filtration system;

3. Although the auxiliary function is useful, it should not be at the expense of the basic performance; pragmatic selection is a wise move.

Floor ceiling air conditioner air conditioning is suitable for family or business scenarios with limited space and high requirements for installation flexibility. In the selection, comprehensive consideration is made from the dimensions of spatial structure, air supply experience, installation ability, performance, and other dimensions so as to truly select products suitable for their own needs.

We are a professional air conditioner manufacturer in China. If you want to buy some floor-ceiling air conditioners for your project, please give us detailed information such as your house type, area, floor, height, and budget. We can provide you with the corresponding plan. If there are any questions, please contact us.

How to reduce the floor-standing air conditioning energy consumption？

In the scorching summer heat, floor standing air conditioners are practically a lifesaver for your home, but the high electricity bills that come with them can be a real pain. With a few tips, you can easily reduce energy consumption. Here are a few practical methods.

1. Optimization of temperature and operation settings

Set a reasonable temperature.

The air conditioning needs to be set at about 26°C; 26°C is the energy-saving gold temperature. When using air conditioners, the energy consumption of air conditioners will increase by about 6%-10% for every 1°C decrease in temperature.

Use the timing function.

Get used to turning on sleep mode or timing on and off, and try to avoid empty adjustment and late operation, especially when the temperature is low at night.

Enable energy saving or ECO mode.

Most air conditioners have “energy-saving mode” or “ECO mode,” and the system will intelligently adjust the operating frequency to maintain comfort while saving energy.

Pre-cooling in advance and staggered peak power consumption.

Turn on the air conditioner early before the high temperature (such as before noon), let the room pre-cool, and help to reduce the cooling burden and save peak electricity.

2. Use habit adjustment.

Avoid frequent switching of the machine.

Frequent starting and stopping will lead to frequent starting of the compressor, which is more power-consuming than continuous operation. Stable operation is recommended.

Use with a fan.

Cooperating with an electric fan or a circulating fan can speed up the flow of cold air and improve the comfort of the body so as to avoid the air conditioning being too low.

3. Environment and space matching

Closing doors and windows to prevent loss of cooling air.

Doors and windows should be closed when using air conditioning. Adding sealing strips and curtains (especially shading curtains) can effectively reduce heat and cold exchange.

Air conditioning matching room area.

Floor-standing air conditioners are generally suitable for large living rooms or open spaces. If the room is too small, the use of a large number of air conditioners will lead to frequent starting and stopping, which means energy consumption is higher.

These methods are simple and practical, and their implementation can significantly reduce air conditioning energy consumption and electricity costs.

We are a professional air conditioner manufacturer in China. If you have any questions, please feel free to contact us!

EVA Case Customization 101 Design & Build Basics

Recently, one of our customers mentioned that it would be helpful for buyers if we could create a blog about Step by Step EVA Case Customization. While this may seem like a basic topic for us, having produced various cases for decades, it can be very informative for buyers who may not have much experience in this area.

Please read the following information, which we hope will help you develop cases that meet your specific needs and are truly fit for purpose.

Outer Shell Material

Polyester and PU are commonly used as outer materials for EVA cases. This is because the outer covering must have enough elasticity to stretch. If not, the material may wrinkle or become defective in certain areas.

As a professional case manufacturer, we provide guidance if our buyers choose their own outer shell material. It's important that the selected material fits the intended purpose.

One example: A customer wanted to use PU for a protective case for measuring tools. While PU gives a premium, leather like feel, we advised against it. His case was meant for use in extreme construction environments, where durability was critical. We suggested 1680D Polyester instead, which is more robust and suitable for such conditions. He agreed, made a sample, and sent it for durability testing. As expected, it passed. He was very pleased with the outcome, otherwise, there could have been complaints from end users if the wrong material had been chosen.

Lining Options

The lining material depends on the type of device inside the case. For example, velvet lining is suitable for optical or watch cases, as its soft, suede like texture helps prevent scratches.

In contrast, devices like medical equipment often require smooth, waterproof linings. These cases must be easy to clean, especially if the inside gets dirty. A suitable lining allows quick and simple maintenance.

Unfortunately, many manufacturers in China use tricot as a standard lining without much consideration. They focus only on cost and production convenience, overlooking the practical use and potential side effects of using the wrong material.

Insert Options

Most of the time, we use die cut EVA inlays as a cost effective solution to hold your equipment securely. However, if the shapes or styles of the items are too complex or not suitable for standard die cutting, we may recommend using an EVA molded tray or CNC foam insert instead. Our solution will be based on the specific details and requirements you provide for your project.

Inside Pocket Options

Besides the main device, extra pockets are often needed for accessories. Many buyers aren’t sure what kind of inner pockets are suitable.

As an experienced EVA case solution provider in China, we usually recommend mesh pockets with elastic bands if the accessories should be easily accessible and visibility isn’t a concern. For accessories that need to stay secure or hidden, such as jewelry, we suggest polyester inner pockets with zippers to keep everything safe and in place.

Logo Options

For a simple, durable, and cost effective solution, debossed or embossed logos directly on the case are ideal. However, if the logo has fine details or complex design elements, alternatives like woven labels, rubber patches, metal plates, or TPU embossed logos may be better.

We’ll recommend the best option to showcase your brand. A well designed case isn’t just protective, it becomes a moving marketing tool throughout the product’s lifecycle.

Zipper Options

For office or kids’ products, we recommend regular nylon zippers for smooth and easy use. For specific industries or functions, waterproof nylon zippers are necessary.

For instance, a customer developing a first aid kit case needed durability in extreme conditions. We insisted on high quality, waterproof YKK zippers. For life saving equipment, it's crucial that everything inside functions properly and stays protected. As a responsible manufacturer, it’s our job to make sure your product performs reliably when it matters most.

Handle Options

Handle choices depend on the case's size and weight. For large, heavy cases, we recommend webbing handles with plastic grip parts for comfort and durability. For smaller, simpler cases, a basic webbing handle can help reduce costs.

We always use suitable components to match the purpose, ensuring our proposals stand out from other manufacturers in the market.

Accessories Options

Whether you prefer metal or plastic accessories, all components we use pass luggage grade loading and aging tests. Whichever case you develop with us, you won’t need to worry about broken parts or user complaints, something we hear often from buyers working with low cost suppliers.

Many factories reduce costs by using cheap, stock accessories. Naturally, this affects the final product quality. With us, you can be confident in what you’re getting.

Finally, we are happy to support your case development, no matter your industry. Our goal is to provide reliable, long lasting products that keep your valuable items safe.

Should Vitamin C Serums Be Stored in Dark Glass Bottles? Why Not Plastic?

The Delicate Nature of Vitamin C

Vitamin C, also known as ascorbic acid, is a powerhouse ingredient in skincare, renowned for its antioxidant properties, ability to brighten the complexion, and stimulate collagen production.However, it's also a highly unstable compound. It's extremely sensitive to light, air, and heat.Once exposed to this substance, vitamin C will be quickly destroyed, lose its efficacy and become useless. Such decline not only prevents you from enjoying all the benefits brought by the essence, but may also cause side effects and skin discomfort.

The Advantages of Dark Glass Bottles

Dark glass bottle (usually amber or brown in colour) act as a shield for Vitamin C serum. The dark glass bottle acts as a natural filter, blocking most ultraviolet (UV) and visible light. This helps to slow down the oxidation process that occurs when vitamin C is exposed to light, thus maintaining the stability and potency of the serum longer. In addition, glass is an impermeable material, which means it is difficult for air to pass through. This better prevents Vitamin C from being oxidised by atmospheric oxygen, which ensures that each product remains undamaged until your end use.

The Drawbacks of Plastic Bottles

In contrast, plastic has several disadvantages when it comes to storing vitamin C serum. Firstly, plastic is usually more transparent to light than dark coloured glass. Even though this plastic bottle is tinted, it still allows more light to pass through, which can speed up the breakdown of vitamin c. Secondly, plastic is a porous material. Over time, air can slowly seep into the bottle through the small holes in the plastic, causing the serum to oxidise. Additionally, some types of plastic may contain chemicals that can leach into the product, potentially causing skin reactions or altering the ingredients of the formula.

How Long Is The Copper Pipe Suitable For My Air Conditioner?

What is the connecting pipe on the air conditioners?

When installing, many people are concerned about the position of indoor and outdoor units but omit the key part—piping length.

The air conditioner connecting pipe, also known as the refrigerant pipe, usually consists of a copper pipe and insulation. It handles the circulation of the refrigerant between the indoor and outdoor units of the air conditioner. Like the artery of the air conditioning system, once its design is not reasonable, then it will lead to low efficiency, compressor malfunctions, etc.

I. Long piping issues

Lower cooling efficiency

The longer the pipes, the higher the refrigerant flow resistance, which reduces cooling and heating efficiency.

Higher energy consumption

The compressor requires more power to push the refrigerant, significantly increasing the power consumption.

Heavier compressor burden

The long and high-load operation may cause the compressor to overheat or even damage.

More installation difficulty and cost

Longer pipes not only complicate installation but also increase the cost of copper pipes, insulation, and cables.

II. Short piping issues

Limited installation

If the indoor and outdoor units are too close, it will be difficult to arrange the piping, fixing, and heat dissipation.

Noise and vibration

If there is not enough buffer distance, the sound of refrigerant flow will be more obvious, and even the equipment may be damaged due to vibration.

Inconvenient maintenance

If the pipe is too short, the operating space will be limited during future maintenance or relocation, which will increase maintenance costs.

III. How long should the copper pipe be?

It depends on the models of the air conditioner and the installation environment; commonly we recommend the following:

Horsepower (HP)	Recommended length (M)	The maximum length allowed (M)
1 HP~1.5 HP	2~3 M	10~15 M
2 HP~3 HP	3~5 M	15~20 M
5 HP and above	5 M and above	25~30 M

Attention: Most air conditioner manufacturers recommend that the connecting pipe should not be less than 3 meters to prevent compressor reverse liquid hammer and avoid problems such as poor refrigerant oil return.

IV. Installation Tips

Use original copper pipes or high-quality refrigerant pipes that meet standards to ensure smooth refrigerant flow.

Ensure complete insulation coverage to prevent energy loss and condensation.

Avoid multiple elbows or sharp bends in the pipes to ensure smooth flow.

If connecting pipes need to be extended, it is recommended to ask a professional and refill it with refrigerant.

Air conditioner connecting pipes should be neither too long nor too short. Proper length is crucial for efficient air conditioning operation. If you're purchasing or installing an air conditioner, be sure to discuss the layout and length of the connecting pipes with your professional installer to avoid unnecessary complications.
