Seal, also known as closed, sealing, packaging containers is a good product, in order to ensure the contents to the transportation, storage and sales process remains in the

container, and to avoid contamination and to conduct variousHermetic Sealing process. Sealed packaging methods and materials and components used in many different types, such as sticky

capping, sealing and custom seal. Sealed package is a more complex technology, designers conducting sealed packaging design, we should consider many factors.


Application

Sealed package seal is any packing the most fundamental and important functions, it can ensure the goods effectively isolated from moisture and air. "Sealed" the literal meaning

of the term, it usually means packing container packaging materials and between external things simply can not be swapped. In fact, there are few absolute sealed packaging.

Almost without exception, have all packaging seals, and successful package always depends on the validity of the sealing performance. Glass was able to long-term preservation

highly sensitive to humidity products, entirely on their own bottles effective sealing performance. If the size of its closures there is a difference, if casting choice of high

permeability, low-barrier-type material, the glass will lose its sealing function and become useless. Sealed Hermetic Packages  technology is the basis for the best-designed

packaging, if the sealing process is not standard, it will make packing tightness lost.

Convenient and easy to use feature is one of the three functions of packaging, convenient features include easy production, storage and transportation easy and convenient

display and sales, easy to open and easy to use and disposal. Transport packaging to be convenient retailers open sales package to facilitate consumers to open and use. Open

mouth with sewing thread like transport packaging cartons, carton sealing tape and are easy to open cans and other forms. Ease of use is to take a clear and concise language or

icon, a product to consumers using the methods and precautions. In daily life, we often encounter difficult situations on food packaging. Such as metal cans of food, there is a

lot of similar problems, but also in open packaging may be harm the human body, such as cut, cut your hands and so on. Plastic food bag had a similar problem, many people travel

or leisure time, because there are not a tool to carry on, there has been embarrassing situation, so bring a lot of inconvenience to the consumer packaging. In addition, this is

difficult to open packaging, sanitary conditions of food is also a threat, such as composite plastic paper tear resulting printed materials in contact with food. Meanwhile, when

such a packaging is difficult to turn on, there is also the problem of non-sealed again, resulting in the contamination of food, however, as technology improvements and updates

material, easy to open and easy to use seal type packaging container for its easy and fast development. On the one hand, easy to open and easy to seal materials such as

composite plastic film, aluminum, tin and other parts replace old skin; the other hand, cans, ziplock, easy to open cans and bottles partially replace rotary last round cans,

seaming style glass bottles. In addition, to meet the athletes in the sport does not have to stop and you can drink the requirements of the United States a packaging company

designs and manufactures a press pull caps. The cap is designed with sip suck Pingzui, the clip will clip on a bicycle water bottle rack available to consumers in the cycling

drink. Canada a long engaged in meat processing company, developed a new polyester materials, packaging, thermoforming top of polyvinylidene chloride co-extruded film sealing,

so that consumers can without difficulty immediately open the package and enjoy the fresh delicious meat.
Tamper alarm function is also called the tamper evident packaging packaging is to allow consumers to some extent, from the appearance of the product display, to identify whether

the victim had been opened merchandise packaging over the packaging. The U.S. Food and Drug Administration will "tamper-evident packaging" is defined as: "Only by opening or

break a show or obstructions in order to obtain an internal product packaging." Tamper used all over the world there are many kinds of packaging including wrapping film bales,

blister (blister) or skin packaging, heat sealing film or elastic wrap film, sealed, Tamper caps, sealed cardboard boxes, metal cans and composite containers.
Packaging for any one manufacturer, the most important thing is to ensure that goods reach the consumer when the consumer can distinguish whether the items inside the package

had already been manipulated to eliminate all security risks. Hands and feet due to packaging passive serious consequences arising from a landmark event, is the 1980s in the

United States, the Yin Tainuo (tylenol) painkillers was artificially contaminated toxic cyanide, which led to the death of the malignant events. Therefore, Tamper design more by

many convenience foods and pharmaceutical factories attention. Although the absolute "tamper-evident" packaging does not actually exist, but manufacturers are seeking ways to

take effective measures to stop those illegal opportunistic theft Sirs wrongful acts. First, they are commonly used method to improve the packaging itself complexity of the

structure, so that those who illegally tamper prohibitive, especially to improve the mouth of the container device complexity. Second is to allow the package to be opened after

leaving visible marks, consumers can identify goods before reaching their hands whether people have been moved "hands."
Basic health and safety requirements
Food hygiene as the basic requirements of food packaging, not only refers to the food to ensure food before reaching the consumer from outside influences, and requires packaging

in food consumption is completed (non-disposable), still able to maintain health, which need of food packaging has repeatedly airtight structure. Whether paper or plastic, most

of the bag structure, health and safety aspects of the existence of common shortcomings, it is a sealed bag full of food must be a consumer is completed, the amount of which for

most food packaging is difficult be done. Some foods on the market do a better job of packaging, such as waves, seaweed wrapper, paperback waves, seaweed can be repeated using a

sealed plastic zipper-type structure can be repeatedly opened and closed, thereby gaining a relative protection of health and safety .
