Sealing wafers, also known as a closed, sealing, packaging containers, in order to ensure that its contents to remain in the container transport, storage and sales process, and to avoid contamination of the various sealing process. Sealed packaging methods and a lot of the materials used and the type of components,

Such stick capping, sealing and set letters and other. The Hermetic Packages is a more complex technology, in sealed packaging design, the designers have to consider a number of factors.


Application

Sealed packaging seal any package of the most fundamental and most important, it can ensure the items to moisture and air separation. The term literally meaning "sealed", it usually means can not exchange between packaging materials and packaging containers of external things. In fact, there is little

Absolute sealing packaging. Almost all of the packaging, without exception, seals, and successful package will always depend on the sealing performance effectiveness. The glass bottle has been able to long-term preservation of the product is highly sensitive to humidity, and its effective Hermetic Sealing rely entirely on glass bottles.

If the size of closures deviation, if the casting choice of high permeability, low barrier material, the glass bottles will lose the sealing function and become useless. Seal of technology is the basis of the sealed packaging, even the best-designed packaging, if sealed process of non-compliance,

Will make the loss of the tightness of the packaging.

Convenient and easy to use function is one of the three major functions of packaging, easy to facilitate the production, for easy storage and transportation, convenient display and sales, easy to open and use and convenient processing. Transport packaging to be convenient retailers on sales package to facilitate the consumers to open and use.

Like with sewing thread on the mouth of the transport packaging cartons, carton sealing tape and cans are convenient to open the form. Ease of use is clear and concise language or icon, methods and precautions such as using a product to consumers. In daily life, by

At leisure, because there are not carrying open the tool, there has been embarrassing, packaging caused much inconvenience to the consumer. In addition, this is difficult to open packaging, the health situation of the food is also a threat, such as composite plastic paper tear lead to printed materials and food

The contact. In the same time, once opened, such hard-to-open packaging, also exists the problem is not repeated sealed, resulting in the contamination of food However, with the improvement of the process and material of the profile, the packaging container with its easy sealing, easy opening, easy to use and quick development. On the one hand, easy to

KEE sealing materials, such as composite plastic film, aluminum and other parts to replace old tinplate; On the other hand, cans, ziplock, easy to open cans and the rotary glass bottles partially replace the last round can seaming glass bottles. In addition, in order to meet the athletes in motion without stop

You can drink under the requirements of U.S. packaging company designs and manufactures a pull cap. The cap design sip suck Pingzui will be caught in the bicycle water bottle holder rack available to consumers in the cycling drinking. Canada has long been engaged in a meat processing company, developed a

A new polyester materials, packaging, top thermoforming polyvinylidene chloride co-extruded film sealing, so that consumers have no difficulty immediately open the package and enjoy the taste of the fresh meat.
Warning function Tamper packaging also known as tamper-evident packaging is to allow consumers to some extent, from the appearance of goods distinguish whether the packaging was open packaging. The U.S. Food and Drug Administration will "tamper-evident packaging" is defined as: "Only by playing

"Tamper packaging used around the world there are many kinds, including wrapping film bundle blister (Blister) or the skin packaging, heat sealing film or elastic wrap film, the inner seal, opened Police

Shows caps, sealed cardboard boxes, metal cans and composite container.
For any packaging manufacturers, the most important is to ensure that goods reach the consumer, the consumer can identify the contents of the package has been manipulated, to eliminate all security risks. Passive hands and feet of the packaging and have serious consequences for a landmark event

, Occurred in the 1980s in the United States, Yin Tainuo the (Tylenol) painkillers were artificially contaminated with highly toxic cyanide, which led to serious incidents of death. Tamper design more and more attention of many convenience food and pharmaceutical factories. Although the absolute

"Tamper-evident packaging do not actually exist, but manufacturers are seeking ways to take effective means to put an end to those opportunistic illegal tamper evident malpractice. One commonly used method to improve the complexity of the structure of the package itself, so discourage illegal tamper evident, especially

Increase the complexity of the device of the container mouth. Leave a visible mark of the packaging is open, and consumers to identify goods to reach their own hands has been moved "hands and feet".
Basic health and safety requirements
Food hygiene as the basic requirements of food packaging, not only the food before it reaches the consumer to ensure food is not subject to external factors, but also for packaging in food consumption (non-disposable), still able to maintain health, which to need food packaging has repeatedly dense

Closed structure. Paper or plastic, most of the bag structure, in terms of health and safety there is a common drawback, that is, once sealed, the whole bag of food must be finished consumer, it is difficult for most amount of food packaging be done. Some foods on the market

The packaging done a better job, such as the packaging of the waves, seaweed, paperback waves, seaweed can be repeated sealed zipper structure plastic bags, can be repeatedly opened and closed, and thus the relative health and safety protection.
