& have spent   Using pre-coating film laminating, can effectively prevent the bubble or mold release coated products.

    The wet glue coating composite processing technology of resin coated products blister and membrane in common, is the film out of the paper to print the substrate, destroyed the paper/plastic composite tight and smooth.

    There are only different forms. Blister is a needlepoint, grain, stripes, crack shape such as local basis. To take off the film is a large area or the whole paper and plastic separation.

    Carefully analyze all kinds of accident case, 'membrane', 'sticky glue' is a basic rule. Longer cause 'membrane', 'sticky glue' change reason, is the glue in wet composite process using adhesives have a large number of organic solvents.

    These organic solvents in the process of production is not fully play, residues in the rubber, are film and paper printing compound.

    Residual organic solvents in the rubber, to be kept in paper/plastic composite movement. For out of the rubber matrix, the volatile escaped into the atmosphere, the movement of organic solvent molecules is in different directions at the same time.

    Part in the middle of the rubber, to soften the glue sticky; Thrust through a rubber, another part of the paper, in the printing ink layer diffusion, ink on paper adhesion and penetration.

    Part of this through the rubber, the membrane movement, gather in the thin film surface, after blocked on the membrane swelling, make it longer, local bump into a bubble.

    Soften the sticky glue, reduce the thermosetting polymer material stick relay; The spread of the ink spread out, with paper attached damage; Membrane swelling, will to outside stretching away from paper printed substrate.

    Using the wet glue coating composite technology, sooner or later, or light or heavy, inevitably appear blister or take off the membrane.

    Of the hot melt adhesive used in pre-coating film without any solvent. There is no organic solvent for rubber to soften and swelling of the spread of the printing ink, thin films, and so on. Polymer materials after thermoplastic stick relay from the heat source, and durable. So can effectively prevent the resin coated products blister and take off the film quality accidents.
