Why most plastic bottles are in round shape?

Today, Most of the plastic bottles are round, only some beverage plastic bottles are square.In fact, The plasticity of plastic bottle is very strong, It not only can shape up the common variety of plastic bottle shape, but also can customize special variety of bottle shape. This is the advantage of plastic bottles that simply created by a pair of mold.

However, Some people would ask why the plastic bottles on the market are mostly round? In fact, That is because the circular plastic bottle is easy to catch, easy to carry, and does not take up space during the transportation.
This is why plastic bottles can quickly squeeze out the market share of glass packaging. We hope we will improve the round plastic bottle into another good level.

The changes of cosmetic bottle packaging

The trend of cosmetic bottle packaging has changed a lot in recent years. In the past, cosmetic manufacturers, which have always attached importance to offline channels, are placing great emphasis on the appearance of cosmetic bottle packaging. Both materials and appearance of the cosmetic bottle are valued by the manufacturers and distributors.

However, in the e-commerce market, cosmetics are the most affected. For online cosmetics bottles, left the off-line counter lighting, and pay more attention to the practicality. Therefore, the cosmetics market over the past two years turned to be simple and practical. This is also a new positive environmental change brought by the cosmetics bottle market.

For cosmetic bottle packaging, the future trend is still lightweight, simplistic, which is the inevitable trend of the future.

The evolution of eye drop bottle packaging

Perhaps because the eye drop products are vulnerable to the bacterial invasion after first time using, So the validity only last for a week.
Whereas the previous eye drop bottles were often between 15 and 30ML. However, It was impossible to use up within a week. It would lead to waste.

After all, a bottle of eye drops price is not low in the current market.This makes the market now have the twist up eye drop bottle in small volume, which can be used for one time only.But because of disposable packaging, the bottle packaging is not precise enough.Suppliers need to improve the packaging in the future.

Offset printing and silkscreen printing on cosmetic soft tube

Offset printing and silkscreen printing on cosmetic soft tube

Both silkscreen printing and offset printing can be used on cosmetic soft tube printing.
Let's see the features of each.
Silk Screening

Silk screening is the technique of printing where ink is forced through a photographically treated screen onto the container to be decorated. The process applies one color at a time, with a new screen for each color. Silk screening produces a clean and elegant look for your beauty logo & artwork. You can feel a nice texture touching the printing surface of the bottles/ tubes.

Silks Screening is idealized for two or three colors printing (but can print up to 6 colors of your choice). Pricing depends on the number of colors.

Advantages of silk screening for cosmetic packaging:
    - Textures can be applied to highlight graphics
    - Idealized for 2-3 colors elegant design
    - High-speed production
    - Various closures: Plastic, Aluminum, Urea, Phenolic, and more

Offset Printing

offset printing on cosmetic  bottles and tubes
Offset printing (on plastic cosmetic tubes) uses printing plates rather than silk-screens to transfer the ink onto the containers. Offset printing is more precise than silk screening, and is effective for multiple colors labeling (up to 6 colors) and printing halftone artwork. Offset printing is idealized on round containers such as plastic cosmetic tubes and bottles. Because plates are engraved for each color rather than making screens, offset printing is more expensive than silk screening. However you can achieve a desirable visual effect for a simple artwork at a reasonable cost.

Advantages of offset printing:
    - More precise
    - Idealized for halftone artwork
    - Multiple colors available
    - High-speed production on round cosmetic tubes

The advantages of the extrusion blow molding

1),The cost of the extrusion blow molding machine is cheaper than that of injection molding machine, about one third of the injection blow molding machine.

2)On blowing molding, the preform is formed under low pressure through the extrusion equipment heat, in this circumstance, the residual stress of the products is small. With its good performance in tensile, impact, bending and other variety of environments, It have the good function.

3)In the injection blow molding, the plastic melt at high pressure (15-140Mpa) through the mold runner and gate, which will lead to uneven stress distribution.

4)The moleculars of blowing mold grade plastics(e.g,PE)are more than that of injection mold.
Such blow molding products have a high impact toughness and high resistance to environmental stress cracking performance, which is very favorable for the large-capacity production of plastic bottles.

5)The wall thickness of the blow molding products can be very thin while the injection molding products cannot be so thin as blowing mold process.

6)Blow molding process can shape complex and irregular products, but the injection molding process has to produce two or more pieces, and then stick it by the glue or bond it or using ultrasonic welding.
