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).

The working principle of injection molding

Injection molding is the main method of thermoplastic plastic molding

Put granular or powder to the hopper of plastic injection machine. Under the heat circumstance, then melt the materials. And maintain the flow state, and then under a certain pressure, through injection machine nozzle and injection mold gating system, the materials inject into the closed mold,after cooling, molten plastic solidified into the plastic parts.

Some common sense on storing medicine bottles

Some common sense on storing medicine bottles

Now, more and more families have the habit of keeping some commonly used drugs, and to prepare for possible period of want or need. Coupled with the modern humanity generally improved, and have a certain understanding of the commonly used drugs, will also increase the consciousness , people however, need to pay attention to some details.
First of all, the date of production on the medicine bottle need special attention, We should check every time before using. It will cause the great harm on the human body by the expired drugs.
Secondly, the drug will be put back to the original medicine bottles, some drugs are stored in brown or light proof bottle, that’s because this drug has requirements of avoiding light, in this case if these drugs are placed in the other bottle apparently will damage the formation of drug.
The desiccant vial, dry cotton do not remove, because when we open the btotle, it will contact with air, the water will affect dry environment required for drug.
Finally, for oral medicine bottles, such as syrup. We should not directly contact with the bottle mouth, because the bacteria will leave in the cork, and will influent the effect of the drug.

We need to avoid eating pesticide mistakenly again

We need to avoid eating pesticide mistakenly again

Some time ago, a man mistakenly recognized pesticide bottle as seasoning bottle, and died from it, This news makes us to reconsider the status of pesticide bottle packaging. It is necessary to analyze, in order to avoid a similar incident happen again.

Firstly, the present features of pesticide bottle packaging is not obvious. The edible oil bottle, generally we see the bottle then we will know what it is. But the pesticide bottle by bottle shape is very difficult to distinguish. It is necessary to form the pesticide bottle packaging features, so that it can effectively reduce the ingestion of the situation. The second, pesticide bottle capacity should not be too large, generally pesticide doses are relatively small, if pesticide bottle capacity is too large, the pesticide placed time will increase, thereby increasing the probability of eating. Finally, the anti-theft pesticide bottle packaging cover need to put more effort, especially to prevent opening efforts without discrimination.

Dishwashing bottles packaging need to be improved

Dishwashing bottles packaging need to be improved

Relatively speaking, Dishwashing market is relatively stable, and has formed a few big monopoly brand. These dishwashing manufacturers might have been in a relatively stable state of the market. Basically dishwashing packaging bottle has no big change. Dishwashing packaging bottle, all except for the color and label area, basically no other changes.
Perhaps this is the reason of more and more illegal imitation dishwashing.
They saw the dishwashing bottle packaging has the advantages of simple design, and almost change little. It difficult for consumers to distinguish the false, which caused much confusion for the detergent bottle market. In this regard, It needs to put on the agenda to accelerate the anti fake performance.
In addition, the dishwashing bottle packaging industry exists many defects, but also the urgent need to improve.

What can we do in avoiding the ban on the use of plastic bottle

What can we do in avoiding the ban on the use of plastic bottle

Recently, we noticed that the news, USA Massachusetts might be issue the plastic bottle ban. Indeed, the plastic bottle is a big risk to the environment. A few years ago, it has issued a ban on plastic bag use,when our country was facing more and more serious plastic bag white pollution, therefore, many of the plastic bottle manufacturers also began to worry about whether China would issue the ban on the use of plastic bottles.
In this regard, we believe that the state will not be promulgated the use of plastic bottles ban. There are several reasons. First of all, The advantage of plastic bottle in the packaging market is obvious, at present, there is no a material container, such as a glass bottle, metal bottle can replace the vacant market of plastic bottle. Secondly, China is a large plastic bottle production country, It has many people engaged in plastic bottles or plastic bottles enterprise, the ban will form a blow to the whole industry, and will face a lot of unemployment. Once again, the plastic bottle pollution and recycling is not ideal phenomenon, but its recovery rate is much higher than that of plastic bags. For example, PET plastic beverage bottle with high recovery rate. Currently, all kinds of facilities are under construction, such as the plastic bottle recycling machine.

Food airless packaging

Food airless packaging

Food airless packaging is a packing method that sealing the goods in airtight container without air. This packaging can prevent outside moisture into the packaging container,and also can prevent being wet in moistureproof packaging when the temperature drops. But we should pay attention to avoid the high vacuum degree.
Such a airless packaging can be used for grain processed commodities packaging.
Airless packaging can not only avoid or reduce food oxidation, discoloration, taste, and inhibite certain fungi and bacteria growth. But still China’s cold storage conditions can not compare with the developed countries, such as Japan, America.
Airless packaging in addition to control temperature and sterile, more important is to control food suitable gas environment, and achieve the purpose of preservation of the expectation. In addition, airless packaging, can also be resistance to mechanical pressure, reduce the oscillation, which is conducive to long-distance transportation, but also conducive to sales.
