Why airless bottle hightlight cosmetics packaging

Why airless bottle hightlight cosmetics packaging

Nowadays, airless bottle packaging received the favour of many high-end cosmetics brand, such as SAMPAR VIVID RADIANCE SERUM,MAMONDE Total Solution Smart Watery Cream, they use the airless bottles to hold the skin care products.
Indeed, airless bottle looks higher grade than other plastic bottles, that is the key one.I think another important factor is that airless environment can well protect our skin care products.
Airless container is in a sealed condition, is can’t get into the air, forming a fully enclosed environment, make the products not polluted by the outside world. It can prolong products saving time, let the large capacity products can last longer. Press type airless bottle design, it is more convenient to use.
Good airless bottle is absolutely don’t have to worry about product residue in the bottom. the airless pump system will press the product to the mouth, even a drop of it. Besides,opaque milk white bottle protects skin care products from oxidation.

Rumor Reusing plastic bottles can cause cancer

                                             Rumor Reusing plastic bottles can cause cancer

Can you really get sick by reusing disposable plastic bottles, or is the link to cancer too flimsy to stand up to modern science?
Chemicals are ubiquitous in our daily life. And one place where they seem to make us most anxious is in plastic bottles, which often hold the liquids we drink every day.
The question of whether those disposable plastic bottles when reused can cause cancer, however, has been mostly answered. Time and time again, some urban legend will pop up claiming that chemicals in the plastic, when reused, are responsible for the spread of certain kinds of disease. And time and time again, those claims disintegrate upon further examination. But the reason these legends persist is that not all of them can be proved wrong.
Not long ago, the controversial chemical BPA was banned from baby bottles and sippy cups over concerns that it could interfere with a child’s nervous and reproductive systems. But BPA is the exception.
However, there is a claim that researchers say hasn’t gotten enough attention: whether heating up a plastic bottle will cause it to contaminate food or water. It says more research needs to be done to determine if there’s any danger.

PET features

PET features

PET plastic material is relatively stable, only at certain wavelengths of ultraviolet (250-350nm) according to the sun, the temperature is higher than 100 ℃,when light reaches 3eV limit actinic it will occur degradation.

PET plastic material does not hydrolyze at room temperature,therefore not afraid of rain and moisture content in the air.
Because PET has good resistance, and thus are not affected by acid rain components.
Production process of PET material generates no pollutants, use process does not produce harmful gases.
Can crushed recycling.
As combustion of waste treatment, due to its caloric value is low and the combustion of flammable and does not produce harmful gases.
Biodegradable polyester can be completely degraded in the natural environment and fertilizer yard, Most final decomposed into CO2 and H2O, no secondary pollution.

Blowing process of different plastic material

Blowing process of different plastic material

1,PE bottle blowing ( Much Softer material, with a solid color, once molded product)
2,PP bottle blowing ( Much harder material, with a solid color, once molded product)
3,PET bottle blowing(Good transparency. Belongs to environmentally friendly materials, two molded product)
4,PVC bottle blowing(hard material, not environmental protection,transparency is worse than PET, but brightness is better than PP and PE , currently less used )

Ink Spray painting

Ink Spray painting

The most common used method of spraying the surface of plastic products can be divided into:
A, Ordinary coloring,Such kind of painring mostly spray by hand. it doesnot have strong abrasion, and easy to swap.
B,PU Varnish oil: Spray on the surface of the plastic product after spraying the base oil.In this way, it can achieve the effect of anti rubbing and gloss finish. General home applicances or daily necessities are treated by PU process.
C, UN varnish oil: Spray a layer of UV gloss oil after spraying the base ink. Both the gloss and rubbing can avhieve a good result. General phone mold products and communications products die more with such an approach.

Printing methods on bottles

Printing methods on bottles

There are several printing methods to print text or pattern on the surface of plastic products.
1,Silkscreen printing
This method is the most common one, it is generally suitable for flat or curvature of small print .
2,curved surface printing
Firstly put the ink into the gravure that curved with text and pattern, then copy the text or images onto a curved surface, the surface will reuse the text or pattern and transferred to the surface of a molded product, and finally curing the ink by heat treatment or ultraviolet light irradiation method.
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

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

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.

Bottle Coating

Bottle Coating

Blocking UV wavelengths can provide you with the protection your product needs. Two of the most common methods used in the past have been absorption and converting; both of these methods only work for a limited time. The longer the UV inhibitor is exposed to the UV Wavelengths the less effective it becomes, shortening your product shelf life. Filtering of UV Wavelengths is just plain bad. In today’s high end displays and artificial light there is a multitude of UV light that is just not being ‘filtered’.
Bottle Coatings has developed a patented two coat process that will eliminate all UVA/UVB and UVC wavelengths from penetration the coating and damaging your product. Continuous exposure is a more serious problem than intermittent exposure, since attack is dependent on the extent and degree of exposure. Many natural and synthetic polymers are attacked by ultra-violet radiation and products made using these materials may crack or disintegrate (if they’re not UV-stable).
