Aluminum foil bag production process

Aluminum foil bag with a metallic luster, good light, is higher for heat and light reflection ability, good isolation, protective, tight gas and vapor, to prevent moisture absorption, gasification is installed inside, not from the bacteria and insects; Shape stability is good wait for a characteristic, thus has been widely used, the following will introduce for you: it's specific production process of aluminum foil bag production process is simple and complicated, the whole production process is: the aluminum smelting & ndash; — Roll casting & ndash; — Cold rolled & ndash; — Intermediate annealing & ndash; — Cold rolled & ndash; — Aluminum foil wool & ndash; — Roughing & ndash; — In the rolling & ndash; — Finishing ( Receives) — — Cutting & ndash; — Aluminum foil product annealing & ndash; — Composite & ndash; — Bag & ndash; — Aluminum foil bag of finished product & ndash; — The packing. In bring about the technological process, starts to produce aluminum foil wool bring about the whole process of plain foil, and then in a composite bag. Production of aluminum foil bag in order to save cost and time, generally choose direct procurement of aluminum foil membrane, and then conduct material composite bag. The bag to make the aluminum foil bag printing factory, and of course the quality of the bags have the how to distinguish the quality, we need to first from material to print to the overall effect of the products after printing. One's physique, aluminum foil bag: strong degree is first divided into two bags fit strong and hot solid degrees. Packaging material is not the same so strong degree is different also. The primary way to distinguish is on the bag sealing side by hand, if it is hard to tear means heat sealing strong degree of good. Vice is not very good. 2, aluminum foil bag material: when the choose and buy can smell first bags with and without peculiar smell, if smell of packaging materials, does not conform to the hygiene standard; The second is may affect the normal use of the packaging bags. On the other hand, you can check bags transparency clarity is uniform, if there are any impurities and so on. Three, appearance neat degrees: to check bags stiffness, give a person the feeling of wrinkle, usually the higher the roughness, the better, but for selection of different requirements, bags made of nylon and high pressure composite membrane, for example at the heat sealing bag will have wavy; Also demand survey bags trimming is neat, as neat as possible. Four, printing quality: we often can see some bags in the market level is very poor product on the shelf, a horror as soon as we see this kind of product. There are some products but also can take off the printing color, this kind of product is defective, but can't happen. Then there is the aluminum foil bag on the surface of the whole degree, does not appear to fold, and so on and so forth.
