composite method of corn seed composite packaging bag

soft packaging materials generally do not use a single material, but have built a series of copper-clad aluminum flat row and line demonstration production line based on composite film. The main compounding methods are as follows:

① wet compounding method. With the continuous development of the enterprise (plastic film, aluminum foil), a layer of water-soluble adhesive is coated on the surface of the substrate, which is compounded with other materials (paper, cellophane) through the pressure roller, and then dried into a composite film through the hot oven. This method is suitable for packaging dry food

② dry compound method. First, the solvent-based adhesive is evenly coated on the substrate, and then sent to the hot drying channel to make the solvent volatilize fully, and then it is immediately compounded with another layer of film. For example, stretched polypropylene film (OPP) is usually compounded with other materials by dry compounding process after printing. The typical structure is biaxially stretched polypropylene film (BOPP, 12 μ m) Aluminum foil (AIU, 9 μ m) And unidirectional stretched polypropylene film (CPP, 70 μ m)。 The technological process is to use a roller coating device to evenly coat the solvent type "dry adhesive powder" on the basic material, and then send it into the hot drying channel to make the solvent volatilize fully, and then use a composite roller to compound with another layer of film

③ extrusion composite method. The curtain shaped molten polyethylene extruded from the slit of the T mold is pressurized by the clamping roll, salivated on the paper or film, coated with polyethylene, or supplied with other films from the second paper feeding part, and bonded with polyethylene as a bonding layer

it used to be 310 years east of the river and 310 years west of the river

our company's main products include: automatic packaging film, food bags, vacuum bags, high-temperature cooking bags, aluminum foil bags, self sealing bags, self-supporting bags, etc.
