Features | Cold roll laminator | IR drying coater | KANA LED UV curing roll coater |
Cost | During production, due to the various sizes of the substrate, Cold laminating film requires large stock volume and has a scrap rate at over 15%. | Infrared radiation dry water-based wet coatings by solvent evaporation which shrinks the initial coating application by more than 50%. The limited length of heating conveyor lower the yield rates to 1-2 m/minute. It is not applicable on heat sensitive substrate. | KANA UV curable coatings have 99.5% solid content of phenolic epoxy resin with additives such as defoamer, leveling agent, photoinitiator and a very little solvents. it costs only 5 to 8g per square meter to apply coatings on various format substrate which can reduce scrap to 2% and increase yield rates to 5-8 m/minute and even 15 m/minute at ultimate load. |
Ductility | The poor ductility of the cold laminating film leads to inconvenience and difficulty in application. | Good ductility leads to easy application | Good ductility leads to easy application |
Quality | The film may easily peel off above +40℃. The Film will easily break below -5℃. Curling, shrinkage, breakage, bubbles and wrinkles happen easily after a short period of time. | If Using A 2kg weight to scratch the coating back and forth at a uniform speed, and the surface coating falls off within 100 times of scratching test. Waterproof quality of IR drying coating is worse than that of UV curable coating. | Excellent adhesion: the coating will not fall off when pulled by 3M tape. Brilliant quality: SGS aging test guarantee no quality change within 1.5 years of outdoor exposure under sunlight and rain and within 48 hours between -20℃ to +68℃. KANA UV curable coating can resist 2000 times of scratching test and 20 times of rubbing with alcohol. |
Color Consistency | PVC laminating film application will darken printing colors due to lower transmittance | the coating surface brightness is among 50°-60°. and it will become darker under high temperature. | KANA UV curable coating has better color consistency due to the higher transmittance. the coating surface brightness can reach 90° -92°. |
Smell | Heavy odor: the odor is difficult to dissipate in a confined space. | Solvent evaporation creates unpleasant smell of ammonia plus environmental pollutants | Only a little smell of epoxy resin. 0.5% solvents solves the problem of volatility and irritation. |
Environmental Friendliness | White Pollution: The PVC laminating film incineration will generate air pollution; PVC takes more than 30 years to decompose. PVC landfill will cause water and soil pollution. | Envrionmentally friendly with no VOCs | Envrionmentally friendly with no VOCs Test report as shown in below pictures |
Human Hazards | Above 65℃, PVC cold laminating film will produce harmful substances and gases such as lead, tin, chlorine, and cause health hazards to humans and animals. | No human hazards | No human hazards Test report as shown in below pictures |
