Test of liquid coating
Detected by photometer: liquid coating brightness is as high as 91.2°
Abrasion test:
The test method is rubbing back and forth 2000 times with a weight of 4 pounds/1.8kg to observe the scratch resistance strength of the liquid coating
Common problems of cold laminating film
- Large loss and high scrap rate
During production, due to the various size of the substrate, and the inconvenience of sticking, the large amount of waste are generated during film coating, and the scrap rate is high as 15%.
- Inconvenient sticking, strong smell
The poor ductility of the cold laminating film leads to inconvenience and difficulty in application. Inkjet printing inks and adhesive materials have a heavy odor, and the odor is difficult to volatilize in a confined space.
- Crimped edges, black edges, wrinkles, bubbles
The film may easily peel off above +40°C and will easily break below -5°C. Curling, shrinkage, breakage, bubbles and wrinkles happen easily after a short period of time.
| Comparison | PVC laminating film(×) | UV coating(√) |
| Cost | Due to the different sizes of the material, cold laminated film requires a larger inventory, and the scrap rate is close to 15% | Coating on substrates of various formats only needs 6 to 10 grams per square meter, which can reduce waste to 2% |
| Application | Poor ductility, inconvenient to use on bus car trailer van sticker | Good ductility and easy to use on bus car trailer van sticker |
| Quality | Prone to shrinkage, breakage, separation and wrinkles | No break, no yellowing, scratch resistance (Aging test report, scratch test) |
| Color consistency | Low transmittance of laminating film will darken printing color | It has high light transmittance and good color consistency. The surface brightness of the coating can reach 90° |
| Environmental friendly | white pollution, air pollution,water and soil pollution. it takes 30 years to decompose. | The coating and the substrate are better combined, and there is no volatile organic compounds. |
| Human hazards | Above 65°C, the laminated PVC film will produce harmful substances and gases such as lead, tin, and chlorine. | No harm to human body (Heavy metal and halogen test report) |
| Smell | Heavy odor: the odor is difficult to dissipate in a confined space. | Only a little smell of epoxy resin. 1% solvents solves the problem of volatility and irritation. |
Material that cannot be coated by cold laminating film
UV picture, leather, tablecloth, knife scraping cloth, wallpaper, wood grain paper, etc. the surface cannot be protected by cold laminating film from color ink fixation and anti-scratch tratment, After a period of time, the picture will be decolorized and the texture is poor.
Liquid coating replace cold laminating film
What is liquid coating ?
- Liquid coating cured instantly by Kana LED UV instant curing coating machine forms a glossy or matte protective film on the surface of soft roll inkjet printing product.
- Coating is high temperature and low temperature resistant (-20°C to 68 °C), anti-yellowing, anti-fracture, scratch-resistant, friction-resistant, environmental friendly, pollution free, safe and energy saving(5kw).
- Under real outdoor test, Kana coating can enduring at least 2 years of sun burning, UV light, water pouring.
Physical characteristics of liquid coating
Due to the limitation of the cold laminating film, micro-bubbles (marked in red) are prone to appear on the surface of the product, and the surface of the liquid coating is flat without defects.
