Touch membrane softening sticky glue

by:Taian Lamination Film     2021-02-04
On the use of touch specular membrane, the use of hot laminating or water-based glue joint again after coating and drying technology, the new touch film laminating in paper surface, so as to achieve a smooth touch the soft handle, special and has high transparency, to ensure that no blind spot after laminating lost. The technology suitable for use in a luxury boxes, the advanced book cover, brand paper products, etc. Widely used in the art of printing industry.

   

advanced Bopp touch membrane carving gravure plate making and printing technology complete printed matter, printed ink layer thick seam, color thick, on paper protruding lines have a certain luster, especially raised the effect of part design, the traditional way of feeling is very easy to use touch to identify raised gravure motifs, simply with your fingertips touch texture can be confirmed that it feels. At the same time, it's obvious bulge, thick and bright color and fine lines in a row, all the visual result that gives a person a kind of special feeling. Is the ordinary offset printing can't replicate appearance reflects the values of its security.

Bopp touch film highlights film production technology in 1958 by Italian Katie company initiative. Industrialize production in Europe and the United States and Japan monopoly in 1962, since its rapid development, currently the world's more than 200 production enterprises, nearly 500 production lines. In our country since the early 60 s by Beijing chemical industry research institute and other units for design and manufacture of two-way stretch technology and equipment, and completed and put into operation in succession some smaller, simple equipment production line, and so far, our country is already the world film Bopp tactility output power, has brought new changes in the supply and demand in China and even Asia.

touch membrane, high-end specialty films, laminating machine is a kind of special velvet smooth surface, with similar peach skin comfortable, strong black velvet delicate texture of BOPP film dud. Products include coating type and precoat type two kinds, namely the thickness of coated products at 20 um, thickness of coating products in 30 um. Degree of full color products, flawless white dot less basilemma, velvet texture, exquisite, durable, high wear resistance, high fog, dumb. Late tactility, using the hot stamping, UV, screen printing.

< br />

using the tactility of film laminating, can effectively prevent the bubble or mold release coated products.

< br />

the wet glue coating composite process of foaming and take off the film laminating products have in common, is the film out of the paper to print the substrate, destroyed the paper/plastic composite tight and smooth.

< br />

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.

< br />

carefully analyze all kinds of accident case, 'membrane', 'sticky glue' is a basic rule.

< br />

'membrane' and 'sticky' change reason, is the glue in wet composite process using adhesives have a large number of organic solvents.

< br />

these organic solvents in the process of production is not fully play, residues in the rubber, composite which is film and paper print.

< br />

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.

< br />

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, violation of ink on paper adhesion and penetration.

< br />

partly through the rubber, the membrane movement, gathered in the thin film surface after blocked, produces swelling to film, make its longer, local bump into a bubble.

< br />

soften hair 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.

< br />

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

< br />

touch of the hot melt adhesive used in membrane 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.
