WATERPROOFING MEMBRANE MANUFACTURER
The manufacturer of pre-applied HDPE membrane will show you: the process of pre-applied membrane
The pre-applied HDPE membrane manufacturer tells you that the pre-coated membrane refers to the process of pre-gluing and rewinding the plastic film, and then compounding it with the paper printed product. First, the pre-coating film processing plant will apply the glue on the film and rewind the film according to the specifications and format used by the pre-coating film processing plant. The manufacturer of pre-applied HDPE membrane tells you that laminating, that is, laminating, is the processing technology of coating plastic film with adhesive and bonding it with paper printed matter after being heated and pressurized to form a paper-plastic composite product.
The manufacturer of pre-applied HDPE membrane tells you that the printed matter after the film has a thin and transparent plastic film on the surface, the surface is smoother and brighter, thus improving the gloss and fastness of the printed matter, and the graphics and text colors are brighter and rich in three-dimensional At the same time, it also plays a role in waterproof, anti-fouling, abrasion resistance, folding resistance, and chemical corrosion resistance.
Process of pre-coating film
⑴The manufacturer of pre-applied HDPE membrane tells you that the thickness of the film is between 0.01-0.02mm. After corona or other treatments, the surface tension should reach 4.0 x 10-2N/m in order to have better wetting performance and adhesion performance.
⑵The treatment effect of the film corona treatment surface is uniform, the higher the transparency, the better, to ensure the best clarity of the printed matter covered.
⑶ The film should have good light resistance, not easy to change color under long-term exposure to light, and maintain stable geometric dimensions.
⑷The film should be in contact with solvents, adhesives, inks and other chemical substances, and the film should have a certain degree of chemical stability.
⑸The manufacturer of pre-applied HDPE membrane tells you that the appearance of the membrane should be smooth, without unevenness and wrinkles, without bubbles, shrinkage, pitting and other defects.
