Aluminum foil bags of aluminum foil using common sense, look at this one is enough!

Aluminum foil is a kind of packaging material has yet to be replaced. It is non-toxic, thermal, shading, moist insulation, incense and other advantages, so use a very wide range. But the aluminum foil in practice, there are still a lot of good. Thus, a professional manufacturer of flexible packaging packaging especially for we adjusted. The category, the use of aluminum foil very extensive aluminum foil is to choose the purity in 99. More than 5% of the electrolytic aluminum, after pressed into. It has a shiny metal luster, non-toxic, tasteless, odorless, shading sex good, reflective rate can reach 95%. High and low temperature stability, temperature of 73 ~ 371 ℃ shrinkage deformation does not go up, good barrier property, moisture airtight, incense, the wet resistance, the resistance of oxygen, it is a high grade cooking packaging excellent middle base material film. Aluminum foil more high-grade packaging and blister packaging for cosmetics, clothing accessories, mouldproof, moisture-proof packaging moistureproof protect incense paper of cigarette, the high-grade packaging of chocolate, leakage proof packaging supplies, li riceses leave flap sealing membrane, sealing trademark of beer and champagne, milk and dairy products and juice compound packing, and so on. 2, aluminum foil rarely use aluminum foil is widely used in flexible packaging, due to its strength is very low, at the beginning of the fold and a brief craze. So rarely used alone. General with paper, glassine paper, polyethylene film made from composite packaging materials, selected according to different kinds of binder separation when cementing compound, dry compound, composite extrusion, stretch film composite, etc. , to compensate for its short split, shortage of softness, no hot glue and other shortcomings. Aluminum foil composite with other materials, other materials of air tightness and moisture resistance should be considered. Aluminum foil with polyester film compound, can greatly improve the resistance to fold function. Three, thickness of aluminum foil in the compound used to consider for aluminum foil compound material guess, 0 in thickness. 007-0. 009 mm and more economical. Now, thinner foil five hundred to six hundred of every square metre perforation, assume that ignore the necessary strength, only has the moisture resistance. Assume that the thickness of it in 20 & mu; M above, can be reached without perforation with the requirements of the moisture resistance. In practical use, in addition to the packaging of food and drugs, on the thickness selection should be based on different built-in objects, especially in the domestic market to sell products, customers to bear ability should be considered.
