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.

Curved surface printing process:
A,Degreasing of the mould.
B,Surface treatment
C,Printing
D,Curing ink

Printing process
A,put the ink into the gravure
B,scrape excess ink
C,extrude the surface to get the ink
D,Transfer the ink to the molded products
E,clean the surface and layout

Transfer printing
Advantages:It can be administered several colors in a single operation.
Disadvantages:Low productivity and cannot get a strong opacity impression.

Hotstamping:
Under controlled temperature and pressure, using the color foils and heat mould that engraved with patterns or font.

How to make good use of plastic packaging

The recovery rate of cosmetic plastic packaging is very low. So it has become one of the sources of pollution.

In recent years, although the increasingly awareness of garbage classification, but the complex material of cosmetic plastic bottle brings many confusion at the time of separation and recovery process.It is a great need to improve the plastic bottle recycling.

There must be a certain rules between plastic packaging and the bottle appearance requirement.It should be try best to make bottle simplify,so as to be recognized by customers, in order to recycling easier.On the other hand, the suppliers should establish a sound recycling channels.If we can achieve and effective recycling and reuse it, it will be a great resources.

Producing spray bottle needs key techniques

Nowadays, more and more fields are using mist spray bottles. Such as cosmetics, pharmas and chemicals industries.So many manufacturers begins to produce and sell the plastic spray bottles.

The nozzle depends on the quality of the spray bottle.And the performance and quality of the spray bottle rely on the use life and experience.But the manufacturers who manufacturing the spray nozzle needs professional technique.

Currently, the nozzle that used in the market are generally produced by professional manufacturers that located in Zhejiang province. Obviously, for a new plastic bottle manufacturer,they need to purchase the spray nozzle from the professional one.If the cosmetic packaging supplier wants to involve into the spray bottle fields, they need to establish production line fo nozzle spray.

Therefore, for those manufacturers who producing spray bottle, they need to know the importance of the nozzle spray and get its key technique.

Mini cosmetic jars and bottles need more attention

 In our concept,Cosmetics bottles must be a large volumn, at least dozens ML. Even trial sample packaging of make-up products , skin care products are the same. There is no special design for the sample packaging. Businesses just take out a bottle from the product for consumer use .

After experiencing many touching with customers ,The cosmetic bottles bottle itself is a bacterial infection base. This is not only irresponsible for customers but also affect the effect of the product.

We strongly recommended cosmetic bottles need specially designed mini- trial sample packaging. This cosmetic bottles can be small, the inside of the product is only enough for one or twice usage. You can duplicate bagged shampoo shower in bag packaging. It is neither wasteful and easy to store . It  will not cause the growth of bacteria after using.

For expensive products , such simple cosmetic bottle sampler can also be used to sell. It is also a big advantage for products. In the absence of the mini bottles of cosmetics packaging industry, it will lead to the emergence of people's attention.

Correct Understanding on transparent plastic bottle

Transparent packaging has become the mainstream in recent years. After all, a transparent plastic bottle packaging allows consumers to see the inside object directly And allows customers to feel the real product and creates a sense of trust for the products.

We all know that the quality of the product got a lot of concerns from customers, particularly in recent years, food safety issues continue to be exposed .Obviously, transparent plastic bottle enables consumer to enhance trust and security for the products. This can not be compared by the other types of plastic packaging.
After considering the markets and the advantages of clear plastic packaging, where a growing number of manufacturers start to produce the transparent plastic bottles, PET bottles, Cream jars in a large quantity.
Although Transparent plastic bottle has many advantages, but there is still living space for opaque bottles and jars.First, chemical plastic bottles , there are many products must be opaque packaging , this is mainly because chemical products are very sensitive to light and must be shielded from light.Second, some sensitive categories of products , privacy class products, but also require the use of opaque plastic bottles. Therefore , opaque plastic bottle packaging market has its own living space.
For us, as the cosmetic packaging manufacturer, both of those markes cannot be neglected.
