Aluminum foil bag printing and cutting technology is introduced

Compound aluminum foil bag printing process in general printing 1 color is CMYK, printed finished aluminum foil bags with different computer displays, the must inform the customer in advance, so as to avoid the customer have drop feeling, and since you are batch printing machine, can lead to the color of the individual is not allowed. Aluminum foil bag transparent background color value not less than 10%, so as not to cause printing can't present at the time of the finished product. If the first batch of printing aluminum foil after completion of the vacuum bags, customers need to printing, because of big machine printing, the color difference is certainly there, need to inform the customer in advance, the sample color shall prevail. 2 1 glue quantity is approximately white membrane. 5 times. When printing to full bottom or larger area, amount of glue should be further expanded. 3 after 13 hours after the first pass of composite curing compound for the second time, product curing 72 hours. 3 the aluminum foil without flattening roller, surface into the composite roller. 4 tension control. 5 oven, the temperature of the composite roller to improve as much as possible. Aluminum foil bag cutting process: 1 aluminum foil bag: cutting edges cut off on the procedure in the production of the required process material, so that the bag or other purposes. 2 cutting the aluminum foil bag: wide sliced into all kinds of materials, to meet the needs of the packaging equipment, meet the packaging specifications. Aluminum foil bag volume classification: the material of large diameter can be divided into many small roll diameter material, easy to use. Aluminum foil bag rewinding: makes a material change direction or impure material winding and tidy, make large volume of small volume. 5 the aluminum foil bag through the slitting/rewinding can correct product appearance defects such as the wrong layer, improve the level of product. 6 points to to the entire length of film quality and inspection, to eliminate defective parts. Theory of these methods can also be mixed use, sometimes to adopt what kind of technology of cutting, after cutting the materials should meet the size requirements, such as cutting material width and length size should meet the requirements of the quality of the aluminum foil bags, such as coil flatness, appearance quality and other technical measures.
