Manufacturing Process Of Aluminum Foil Bag

Dec. 10, 2019

Aluminum foil bags are mostly used in various precision components, semiconductor devices, electronic computers, electronic communication equipment and integrated circuits, such as microelectronic products and food vacuum packaging and medical packaging. What are the types of aluminum foil bags? How can we tell what kind of function the aluminum foil bags are? What is the manufacturing process of the moisture-proof aluminum foil bags? Anti-Static Shielding Bag Supplier will share with everyone!


Anti-Static Aluminum Foil Bag


Anti-Static Aluminum Foil Bag


Aluminum foil bags can be divided into moisture-proof type, Anti-Static Aluminum Foil Bag, vacuum type according to function, and can be divided into food packaging, medical packaging, electronic packaging, mechanical packaging, hardware packaging and so on. Aluminum foil packaging bags have been dissolved into our lives and are also the most common and convenient one. Aluminum foil bags are mostly used for moisture-proof, anti-static, and light-shielding packaging of electronic chips, ICs, optoelectronic products, precious metals, food, and medical and medical machinery.


Common structures are: PET / AL / PE or CPET / AL / PA / CPP and PET / AL / PA / CPE.


PE is suitable for low temperature use, CPP low temperature food packaging film, NY to increase physical strength, puncture resistance, tensile properties, AL aluminum foil is to increase barrier properties. The outer layer is NY film (15UM), NY is polyamide, nylon, nylon, high mechanical strength, high softening point, heat resistance, low coefficient of friction, wear resistance and good electrical insulation. The inner layer is a CPE film (120UM). CPE is a chlorinated polyethylene. It is made from high density polyethylene (HDPE) by chlorination. Aluminum foil is to increase the barrier properties. So it has opaque, silvery white, with anti-gloss, barrier properties, heat sealability, optical rotation resistance, high temperature resistance, low temperature resistance, oil resistance, fragrance retention and other characteristics. Generally, the higher the flatness, the better. If the compound is not good, there will be sandwich wrinkles or corrugations, and the edges are neat, which can better indicate that the product is qualified.


The production process of aluminum foil bags can be divided into six parts: compounding-coating-curing-printing-slitting-bag making.


Compounding is the bonding of different materials through hydrosol water, such as PET and AL and NY. Care must be taken not to cause sandwich wrinkles, which do not stick together.

The coating is to apply an antistatic liquid to the intermediate layer or the surface layer of the medium as required. Need to be coated evenly on the surface or inner layer.

Curing is to cure the coated or composite product through a certain temperature for a certain time, so that it is sticky and cut and the water is evaporated.

Print on the surface or intermediate layer to print the required pattern or text, but there must be no offset and less printing.

Slitting is cut into different specifications of semi-finished products according to different requirements.

The bag-making is made into a finished product according to a certain requirement according to the cut product.


In short, the product features are: opaque, silvery white, anti-gloss, good barrier properties, heat sealability, light shielding, high temperature resistance, low temperature resistance, salt fan resistance, moisture resistance, oil resistance, fragrance retention, nontoxic Tasteless, soft and so on. So the aluminum foil packaging bag has dissolved into our life and is also the most common and convenient type of packaging bag. Aluminum foil bags are mostly used for moisture-proof, anti-static, and light-shielding packaging of electronic chips, ICs, optoelectronic products, precious metals, food, and medical and medical machinery. Our aluminum foil bag manufacturers can also customize Anti-Static Shielding Bag, vacuum bag, anti-static protective tape and other products according to your needs.


The above is the production process of the anti-static aluminum foil bag shared by the aluminum foil bag manufacturers.
