Water-based laminating adhesive film laminating mechanism is the liquid glue evenly coated on the film directly with the printed paper wet bonding, through the penetration of adhesive molecules to achieve the purpose of bonding. Now it is worth noting several issues raised in the compound process for your reference.
① adhesive for the water-based glue, to the composite print must have a strong water absorption, poor water absorption of the print can not be used with this type of plastic compound.
② For printing products such as gold and ink, you must first sample, only the absence of color reaction of gold in order to batch use.
③ complex products in the retractable stick, only to be transparent after the film can be cut off, about taking about 20 minutes.
④ If the need for laminating products squeeze bump, it must be set aside for 24 hours later.
⑤ laminating after the cardboard if there is a corner play warping, may be too much glue, resulting in plastic shrinkage caused by too much stress, or cardboard moisture content is too high, should be controlled.
⑥ glue from different manufacturers can not be mixed to avoid glue polymerization, etc., affect the Fumo effect.
⑦ For the temperature below 10 ℃, be sure to test the low temperature activity of the glue before use, if the low temperature performance is not good, be sure to use the water bath heating method to make the glue temperature of 10 ℃ or more. So as to achieve the purpose of full bonding.
