Abstract

The invention discloses the coating technique of a kind of low thickness film and low grammes per square metre label paper, soften including gluing, drying tunnel, mold sizing, water suction anti-roll, on line rolling, draw the steps such as film, by using the BOPP film of 10UM, reduce the anti-contractility of film, water vapour is absorbed uniformly plus label back side of paper, paper further obviates the anti-contractility of film in rewinding type-approval process, makes label paper the most smooth stable at the finished product drawing film and die cutting procedure, and more manual overlay film effect is more preferable；And use low thickness film, greatly reduce production cost；Both ensure that the efficient production on full-automatic laminating machine of the low grammes per square metre label paper, and the most thoroughly solved the difficult problem that overlay film paper is Texturized, further enhancing overlay film effect simultaneously, improve product quality.

Description

Low thickness film and the coating technique of low grammes per square metre label paper
Technical field
The present invention relates to the overlay film of printing packaging technical field, a kind of low thickness film and low grammes per square metre label paper Technique.
Background technology
At present, printing packaging enterprise, when producing bottled food label, typically can use thickness in the surface of paper after print The BOPP film of 12UM is made coating technique and is processed.Automatic mulch applicator is to use heat to cover glue to complete label overlay film through hot-rolling or Hot-blast Heating , but label gram degree is low, and buckling deformation easily occurs, and has a strong impact on label and uses at the labeling of customer.In order to make it not Texturized, usually use the cold glue that covers to complete coating processes on the manual laminating machine do not heated, but this mode production efficiency Low and overlay film less effective.Therefore, how to utilize automatic mulch applicator to realize the production of the high-quality and efficient overlay film of bottled label, be to put Technical barrier urgently to be resolved hurrily in face of us.
Summary of the invention
The problem existed for above-mentioned prior art, it is an object of the invention to provide a kind of overlay film effective and be not susceptible to The low thickness film of curling and the coating technique of low grammes per square metre label paper.
The technical scheme is that the coating technique of low thickness film and low grammes per square metre label paper, comprise the steps:
(1) gluing: select the BOPP compliant membrane of 10 μ m-thick by label antiquarian, be arranged on laminating machine upper winding shaft, film is worn Guiding to glue spreader position, glue spreader is put into glue basin and is coated hot compress glue toward the one side of BOPP film；
(2) drying tunnel softens: by smooth for the BOPP film after gluing covering in the low grammes per square metre that the grammes per square metre needing overlay film is 70 grams-100 grams On label paper, the label paper after overlay film passes through a long 80-100, and temperature is the drying tunnel of 50-55 DEG C, and BOPP film is at height Soften under the effect of temperature；
(3) sizing is molded: the label paper being covered with BOPP film after drying tunnel softens is guided to laminating machine pressure roller position, completes mould Compression set type, the temperature of pressure roller is 38-42 DEG C, and the pressure of pressure roller is 15～20MPa；
(4) water suction anti-roll: use steam spray device toward the label paper back spraying steam after overlay film, make back side of paper uniform Absorb moisture content；
(5) on line rolling: rolling speed is 15～25m/min.
(6) film is drawn: after 72 hours, draw film.
Advantages of the present invention: 1, use the BOPP film of 10UM, reduce the anti-contractility of film, add that label back side of paper is equal Even absorption water vapour, paper further obviates the anti-contractility of film in rewinding type-approval process, makes label paper draw film And the finished product of die cutting procedure is the most smooth stable, more manual overlay film effect is more preferable；And use low thickness film, greatly reduce Production cost；2, by increasing water vapour, and set corresponding temperature, pressure, speed, both ensure that low grammes per square metre label paper existed Efficient production on full-automatic laminating machine, the most thoroughly solves the difficult problem that overlay film paper is Texturized, further enhancing simultaneously Overlay film effect, improves product quality.
Detailed description of the invention
In conjunction with specific examples below, the invention will be further elaborated.
Embodiment 1
Select the BOPP compliant membrane of 10 μ m-thick by label antiquarian, be arranged on laminating machine upper winding shaft, film is connected gluing Roller position, glue spreader puts into glue basin toward hot compress glue in the one side of BOPP film；Then smooth for the BOPP film after gluing covering is being needed Wanting on the low grammes per square metre label paper that grammes per square metre is 70 grams of overlay film, the label paper after overlay film is long by 100 by one, and temperature is 50 DEG C drying tunnel, BOPP film softens under the effect of high temperature；Then the label paper being covered with BOPP film after drying tunnel softens is drawn To laminating machine pressure roller position, completing to mold sizing, the temperature of pressure roller is 42 DEG C, and the pressure of pressure roller is 18MPa；Use laminating machine certainly The steam spray device of band, toward the label paper back spraying steam after overlay film, makes back side of paper uniform pickup moisture content；On line is received Volume, rolling speed be the speed of service of 15m/min, i.e. complete machine be 15m/min；Film is drawn after placing 72 hours.
Embodiment 2
Select the BOPP compliant membrane of 10 μ m-thick by label antiquarian, be arranged on laminating machine upper winding shaft, film is connected gluing Roller position, glue spreader puts into glue basin toward hot compress glue in the one side of BOPP film；Then smooth for the BOPP film after gluing covering is being needed Wanting on the low grammes per square metre label paper that grammes per square metre is 100 grams of overlay film, the label paper after overlay film is long by 80 by one, and temperature is 55 DEG C drying tunnel, BOPP film softens under the effect of high temperature；Then the label paper being covered with BOPP film after drying tunnel softens is drawn To laminating machine pressure roller position, completing to mold sizing, the temperature of pressure roller is 38 DEG C, and the pressure of pressure roller is 20MPa；Use laminating machine certainly The steam spray device of band, toward the label paper back spraying steam after overlay film, makes back side of paper uniform pickup moisture content；On line is received Volume, rolling speed be the speed of service of 25m/min, i.e. complete machine be 25m/min；Film is drawn after placing 72 hours.
