How to remove the residue of the glues

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

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

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.

Shortage of outdoor bottle packaging

Shortage of outdoor bottle packaging

Today, outdoor travel has become the ideal outdoor sports leisure way, also gradually to the attention of the people. Outdoor fishing is not just the elderly love, quite a number of young people also enjoy it.

According to the market situation of bait plastic bottle orders gradually increased every year, for a long time, plastic bottle manufacturer for bait packaging is seldom, and there is no professional technical support, some buyers have no choice, only can choose from the regular plastic packaging.

Purchase some simple ordinary plastic bottles, and after their late processing to meet the demand but in the process of fishing, is quite important, how easy it is to take the bait out from the packaging.

For Canvard Packaging, also has some simple bottle packaging that fits the baits.
