Dongguan independent zipper bag manufacturer tells us that vacuum packing bag should not be too thick
The range of food packaging bags is very wide, including dried fruit bags, coffee bags, tea bags and so on. With the change of packaging technology and information, the problem of the thickness of packaging bags gradually emerged. Many composite bag manufacturers and aluminum foil bag manufacturers have too much thickness of packaging bags, which will not be borne by consumers.
Originally, the production of food packaging bags to comply with a fundamental principle, that is, its thickness should not be too thick. First of all, it is divided into transparent and opaque in appearance
The production of packaging bags should pay attention to the appropriate thickness, that is, it can not be too thick or too thin, self-supporting zipper bag manufacturers introduced too thin packaging bags can not play a protective role in packaging, encountered some external forces pull very simple will be damaged, other if the package is too thin If the food is wrapped with oil inside the bag, the oil will penetrate into the outside through the inside, thus affecting its quality. In addition, too thin food packaging bag is greatly affected by the environment. It is easy to differentiate under the sun exposure and rain immersion, and its thickness should be strictly controlled.
Too thick guarantee bags also have many disadvantages. They can shorten the storage time of food. Self supporting zipper bag manufacturers introduced that in addition, too thick packaging bags are very harmful to the environment, and they will not decay after many years. This is inconsistent with the proposal of energy conservation and environmental protection initiated by the state, and it is not attributed to the environmental protection products supported by the state. In addition to the above two points, the sealing of too thick bags is relatively laborious. Many too thick bags are not particularly good in sealing, and they are easy to crack. http://www.ycritai.cn/
