How does the hand sanitizer create foam?

How does the hand sanitizer create foam?

How does the hand sanitizer create foam? It is caused by air pressure. The hand washing liquid is manually pressurized to hydraulically wash the hands. The mousse bottle is with high pressure when it is filled. It has pressure and will automatically spray as long as the bottle mouth is pressed.

Compared with ordinary hand sanitizers, foam hand sanitizers have innovative breakthroughs in function and concept. To put it simply, the foam is relatively rich, and the foam is directly pressed. It can be disposable or washed. This type of foaming hand sanitizer is relatively water-saving to clean and relatively clean and easy to rinse. The principle is that there is a special device at the mouth of the bottle to fully mix the air with the foaming agent. I haven’t seen a foam gun for firefighting. I must have done such an experiment in a middle school. The drooping paper floats to the place where the gas flows, because the fluid has a decompression effect. The foam gun has a common nozzle in the middle, and there is a hole with many holes on the side. When the foaming agent is sprayed from the middle of the sleeve, a large amount of air is drawn in from the side due to the decrease in air pressure, and it is mixed with it to generate foam.

How the airless pump bottle can be reusable

When the airless pump bottle is pressed, the bottom piston will run up to squeeze out the contents. When the contents are used up, the piston has already run to the top. You can remove the pump head and re-install it, or use a hard object The piston tops to the bottom and is ready to be used again.

Airless bottle refers to a container that can isolate gas from the outside temperature or a container that isolates external bacteria. The contents of the airless bottle can be completely isolated from the air to prevent the product from oxidizing and deteriorating due to contact with air, which can breed bacteria. The airless bottles commonly used in the market are composed of a cylinder and an oval container and a piston at the bottom. Its design principle is to use the contraction force of the spring and prevent air from entering the bottle, creating a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward.

Why is the bottom of the plastic bottle recessed

 

The bottom of the plastic bottle is recessed to allow the beverage bottle to stand firmer. If it is a flat-bottomed plastic bottle, it is easily deformed due to the hydraulic pressure, and it usually protrudes outward, so that the beverage bottle is not stable. However, if the bottom is designed in the shape of a groove, the stress area of ​​the bottom is increased, and the pressure is reduced, so that it is not easy to deform. And even if the entire bottom does not touch the table, as long as the force is uniform, it can stand very stably. The stability of the five-claw shape is very good, so a large part of the common plastic bottles are made into a five-claw shape. Plastic bottles are usually only disposable. If you use it to hold hot water, you will notice that it will deform and either bulge or shrink. In addition to becoming strangely shaped and difficult to stand, plastic products also release toxic substances at high temperatures.

Common packaging box structure

Common packaging box structure are divided into five types: 1. Portable hand bag, because some products are large in size. In order to make it easier for customers to carry, the handles will be added to the packaging box and can be folded or hidden. 2. Heaven and earth cover boxes, they are differently round shape with tangent lines. You can open the cover to see the goods, as well as the characters and trademarks. It is easy to open and easy to take out the goods and display as well as promote the products. 3. Special-shaped packaging color boxes have various shapes such as rhombus, octagon, hexagon, circle, triangle, etc. This packaging color box uses arcs, straight lines to cut and alternate the combination of faces to produce packaging color boxes. 4. Window-type color boxes, which are divided into partial and multi-faceted windows, also use transparent plastic film, no plastic film, PET film, mainly showing the goods for consumers to buy. 5. Special box type, some add an additional accessory, some open the gap, some open the hole add a quality product, mainly based on the different uses of different products for the corresponding design. There are many types of packaging color boxes on the market, with different shapes, and the unique structure has an indispensable role in promoting product packaging promotion and attracting consumer purchases.

Why choose a PET bottle

Why choose a PET bottle

In recent years, we have found more and more cosmetic brands on the market using pet lotion bottles. So why is pet lotion packaging so popular? First of all, the glass or acrylic lotion bottle is too heavy, and the weight is not conducive to carrying out. As more young people travel, the pet lotion bottle package is more convenient to carry. It is also more portable. Secondly, with the rise of online shopping, lotion bottles often break or have other damaged conditions during transportation, while pet lotion bottles are shatter-resistant, and collisions and extrusions during transportation will not cause problems such as breakage and leakage. Once again, pet lotion bottle packaging is relatively simple to produce and low in cost, so it is also popular.

How to select a good PET bottle?The answer is choose a new material. Some plastic blow molding manufacturers will use the secondary material to process the pet lotion bottle, which obviously affects the quality of the emulsion. Therefore, special attention should be paid to the raw materials produced by the lotion bottle manufacturers. Besides, price is also important, the lotion bottles are used in large quantities, so you need to control the cost as much as possible In addition, the stability of the supply of the emulsion bottle packaging manufacturers, and the timely delivery is also crucial for the late stage of the emulsion manufacturer.

Once again, facial cleanser bottles are more upscale in appearance, and facial cleanser tube give people a cheaper feel.

Which one is more practical,It still needs to be treated differently. It should be distinguished according to actual usage.

Three types of cosmetics using cosmetic plastic tubes

Plastic cosmetic tubes are made of PE materials, which are widely used plastic materials. It is suitable for the production of cosmetic tubes. It has the advantages of softness, corrosion resistance and size. It can be used for facial cleansing, eye cream, hand cream and other cosmetics. The tube is durable and reliable, and the price is reasonable. It is neutral in all packaging. The ratio is higher, the following three common tubes are available for everyone to choose from.

The biggest difference between silk screen and offset printing in cosmetic plastic tube

The biggest difference between silk screen and offset printing for cosmetic plastic tube is:
1. There is no dot on the silk screen, and there is a dot on the offset printing. It can be seen obliquely to the light.
2, silk screen is generally thicker than Luo, look carefully there will be some unsmooth sides, offset printing is relatively regular, horizontal and vertical.
3, all images (such as colorful pictures) can only be offset, not silk screen.
4, common monochrome simple graphics, text, can be silk screen. Some small silk screen prints will have some raw edges and can be seen carefully.

Tube manufacturing process

The process of making cosmetic plastic tube is also called tube extension, and the production equipment is called a pipe drawing machine in the factory. The printed rolling sheet goes through the following steps after entering the machine:

1. Trimming: According to the tube diameter to adjust the feeding width of the sheet so as to match the drawing rod.
2, Shaping: The sheet is flat,you have to use a special mold to turn it into roll shape.
3. High-frequency welding:The high-frequency machine starts to work after the tube sheet enters the position of the high-frequency welding knife. Then weld the front and back of the tube sheet together under a proper temperature. At this time, the tube sheet has become round.
4. Cursor Sensing: Use the light cursor to sense the cut pipe mark printed on the material, the machine can distinguish the length of the tube body of each tube. This step is very important.
5. Tube cutting: The last step is to use the cooperation of the cutter and the cursor sensor to cut the welded tube into a product of uniform length.

Printing introduction of plastic cosmetic tube

Printing introduction of plastic cosmetic tube

 

There are three processes in sheet printing of cosmetic tubes. Generally, offset printing is first carried out on aluminum-plastic sheet. The biggest advantage of this sheet is that it can print beautiful patterns and achieve photo-quality effects, which is widely recognized by customers. The other is silk screen, this is the same as the silk screen mentioned in the previous article. Although the silk screen is strong and beautiful, the silk screen can’t print the pattern, only the simple text or LOGO can be printed, and the silk screen has the problem of inaccurate positioning. Text in different colors cannot be too close.
