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).

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

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

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

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

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 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.

How to remove the residue of the glues

Tape is often used in our daily life, but it is a headache to remove the residual sludge of
the glues. Now we share some good method to solve that problem.
Method 1, Alcohol, chean with few alcohol. Easy to remove in a short time.
Method 2, Acetone, qicker cleaning the residue, better than aocohol.
Method 3, Nail polish remover, the same cleaning method as previous one.
Method 4, Hand cream, cleaning back and forth.It is Grease-like material, its nature is
incompatible with glues. This is the theory to remove the glues.

Production technique of blowing mold

Plastic bottle production and blow molding technology has now reached a higher level.However,Plastic bottle production from raw material to the bottle blowing equipment to bottle blowing mold and to bottle preform, there are many room for improvement.
As for the bottle blowing mould, We don’t think now bottle blowing mould cost is low. For the development of a new bottles requires a high investment cost. One of the reasons for such a high price is the production of bottle blowing mold steel material. Therefore finding alternative steel material, is one of the effective methods to reduce the bottle blowing mold cost. In addition, the weight of the bottle blowing mold tend to be heavy, a bottle blowing mold can only corresponds to one bottle shape. The improvement of bottle blowing mold structure makes a bottle blowing mold accommodates more bottle shape.
All in all, bottle blowing mould improvement of production techniques and defect will greatly promote plastic bottle production efficiency and reduce the production cost of plastic bottles.

The safety of PET bottle

May be you wonot know most bottled water comes packaged in polyethylene terephthalate (PET or PETE) plastic bottles. The widespread use of these bottles, some 85 percent of which never get recycled, according to the Container Recycling Institute, has raised ire among environmentalists. But do PET bottles pose a health risk? At this point, the evidence to suggest they might appears to be limited and preliminary.

Most health concerns about chemicals in plastic bottles relate to bisphenol A, that is No7 at the bottom of bottles, that is usually used in the milk bottles. That hormone-mimicking chemical, which can disturb the body’s endocrine system, has been found to leach from polycarbonate plastic, which is used to make certain sturdy, reusable water bottles (such as those that hikers often carry), baby bottles, and water coolers. But PET bottles donot contain bisphenol A, according to the National Association for PET Container Resources (NAPCOR), a trade association for the PET plastic industry. Scientific research on the potential for PET bottles to leach harmful substance is sparse.

If anything, it is the reuse of PET bottles by some consumers that may pose a problem, since the bottlesnarrow necks can make them difficult to wash. “The bigger risk to consumers is probably bacterial contamination,” says Rolf Halden, a drinking water expert and assistant professor at the Johns Hopkins Bloomberg School of Public Health.

For people with healthy immune systems and reasonably good washing skills, however, even this risk of microbial contamination remains slight. And some people, of course, never reuse the bottles. The EPA, in a document entitled “Bottled Water Basics,” says: “Drinking water (both bottled and tap) can reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk.”

According to NAPCOR, the plastic in PET bottles is inert and does not leach harmful materials into its contents—either when a beverage is stored unopened, or when bottles are refilled or frozen.

Not everyone buys that line, however. William Shotyk, a geochemistry professor at the University of Heidelberg, has published two studies (here and here) that show that antimony, a potentially toxic trace element, leaches from PET bottles over time. This doesn’t mean there is a clear health risk, Shotyk says. But, he adds, “I would say it’s something to think about.”

“The amount of antimony in natural water that is not contaminated is extremely low,” he says. “The amount of antimony in bottled waters is hundreds, sometimes thousands, of times higher.” Still, Shotyk found it at levels no higher than two parts per billion (ppb), and EPA drinking water regulations permit antimony to occur at up to six ppb.
