Laminating is a very important post-process of advertising production, the quality of laminating is closely related to the finished product, but in the process of laminating will always be wrinkled and blistering phenomenon, what is the cause of this phenomenon? And how to solve it?
The reasons for laminating film wrinkles:
1, cold laminating film single side of the elasticity is large or two sides of the middle of the loose tight caused by the picture is not flat caused by the laminating film wrinkles. Should choose to match the temperature of the oil, pay special attention to the northern winter indoor and outdoor temperature difference is very large.
2, the raw material of one side of the elasticity or two sides of the loose middle tight caused by the paper surface is not flat caused by wrinkles in the laminating film. Should do a good job in the production process of the original film, semi-finished products, finished product inspection, empty walking film laminating machine more than 5 meters, no wrinkles before allowing the production of storage.
3, laminating film operating speed is not uniform, high and low, operating tension is too large, stretch film, will cause wrinkles laminating film. Should be operated correctly, the conditions of the use of low-temperature cold laminating machine, such as Mefu (Mobil), low-temperature 40 ℃ cold laminating, to avoid wrinkles, blistering and fogging.
4, laminating machine quality varies, with poor laminating machine laminating film caused by laminating wrinkles. Or laminating machine failure, transverse and longitudinal tension is too large, stretching the film caused by the laminated film rebound, caused by the laminated film wrinkles. The machine should be inspected regularly to ensure trouble-free operation.
Reasons for blistering of cold laminating film:
1, the inkjet layer is not dry, the solvent has not evaporated. Should assist in drying or postponing the laminating time, so that the picture dry thoroughly.
2, inkjet layer is too thick, table dry solvent residue evaporation is not out, laminating a period of time, the solvent outward evaporation caused by blistering. Should reduce the inkjet thickness.
3, laminating process, the surface has dust impurities, impurities at the pressure is not solid, resulting in air residue, blistering. Should keep the operating environment clean and less dust.
4、Cold laminating film glue coating is not uniform, thin, poor adhesion. Should improve the amount and uniformity of glue coating.
5, cold laminating film glue holding power is poor, blistering after a period of time. Apply the correct use of glue varieties.
Cold laminating film fogging causes:
Cold laminating film fogging is actually a way of describing the cold laminating film after laminating the picture, there are a lot of foggy white spots, and can not be eliminated for a long time, fogging phenomenon in winter more than summer. The main reasons for fogging are:
1, the release base paper lamination is relatively thin, uneven, the texture of the base paper will lead to cold laminating film adhesive surface is not flat, after framing the picture, the prominent adhesive point will be very good fit the picture, but concave into the adhesive point will be foggy white spots to show. Cold laminating film framing picture the chance of foggy spots, glossy materials (such as glossy photo paper, etc.) will be significantly more than matte materials (such as adhesive backing, etc.), dark color ink out of the picture is significantly more than the light-colored picture. Should choose the thick film, surface flat release paper as backing paper, especially the production of matte cold laminating film.
2, cold laminating film glue thickness is not enough. Before the earliest cold laminating film glue thickness is generally in 16μm or so, with the vicious competition in the market, the glue thickness once from 15μm down to 10μm or even 8μm, in the laminating picture, due to the picture material and the amount of different ink, glue thin will directly lead to a lot of fine places can not be very good fit, the fog point will be from this, and due to the glue is too thin resulting in the fog is very difficult to completely eliminate. Should be strictly coated with glue weight standards, do not sacrifice product quality in order to reduce costs.
3, a cold laminating film in different temperature environment, will show different glue state: summer laminating is not no fog point, but due to the high temperature, fog point elimination fast; winter temperature is low, glue “activity” is not high, often need 1-2 days or even longer elimination of fog point. Should improve the winter glue weight standard, the same product is generally higher than the summer 2-3 g / m².
4, due to the operation and environment caused by dust, and cold laminating film blistering similar, tiny dust caused by the film and painting adhesion is not solid. It should be operated correctly according to the requirements of the laminating machine, to ensure a clean environment, as far as possible without dust.
