The abrasion resistance of ink is related to the quality of the resin material used. The level of abrasion resistance directly affects the dry-friction resistance of printed products during handling. After corrugated cartons are printed and printed, they must be repeatedly subjected to the friction of carrying, reloading, and loading and unloading to finally reach the consumers. Therefore, the abrasion resistance of ink blots is an important assessment index for ink painting.
Light-resistance performance: Paper-based packaging prints are transported, stored, and displayed many times after being produced by a production company until they finally reach the consumers. Products printed with inks that are poorly light-resistant are in compliance with the requirements of the paper-based packaging manufacturing company, but color deviations or discoloration may occur after circulation. As a result, there will be controversies between the supply and demand sides. This is also a piece of information that should not be overlooked when the standards are formulated.
Solid content refers to the proportion of solid content of water, resin, pigment, and other additives in the water. The solid content of the ink and ink has an effect on the economic indicators and quality indicators of the ink. Solid ink content should be ≥ 45 ± 5%.
Fineness refers to the size of the toner particles in the ink. It is an important quality indicator. The fineness of the ink should be 10 to 20 μm.
(Level 2) Packaging, Storage and Handling Requirements for Flexo Printing Water Based Inks
Packaging containers and their identification
Sealing packaging ink with plastic buckets can meet the requirements. The packaging should prevent ammonia and alcohol substances in the ink from evaporating. It can prevent dust from falling into the ink and cause the ink ink performance to be unstable. In addition, each ink type, package weight, delivery date, expiration date, manufacturer and contact information should be marked and described.
? Handling, storage and storage requirements
Ink and wash should be lightly loaded and unloaded to prevent damage to the packaging and containers, and be stored in a cool, dry place. After the inks have been left for a long time, some poorly stabilized inks are prone to sedimentation, delamination, and, in some cases, false thickening, and can be fully stirred before use. When using fresh ink, be sure to mix evenly in advance, and then use thinner for dilution adjustment.
(a) inspection and acceptance rules
When performing spot checks on each batch of ink, the ink-and-wash standards should specify: the method, proportion, and criteria for the determination of flexo-printed aqueous inks. The inspection and measurement methods and inspection methods formulated for the inspection, in addition to the large enterprises, can also meet the actual operations and monitoring of ink and wash ink by small companies.
(a) inspection tools and instruments
Manual color development wheel, standard color model, coated 4# cup, PH tester, chemical reagent, friction tester, and other items.
