How can I compare PP ink grades for adhesion, drying speed, and outdoor durability?

Compare PP ink grades by testing adhesion on the actual substrate, recording drying performance under the same process conditions, and evaluating outdoor durability through standardized exposure checks. The supplied PP ink data confirms compatibility with shampoo bottles, cosmetic bottles, stationery products, and batteries, with screen, pad, offset, and screen flexographic printing support. Use colorfastness, fineness, viscosity, and flowability as additional comparison indicators.

Core Solutions & Key Takeaways

• Test adhesion directly on the intended PP product surface because the provided data identifies applicable objects but does not state a universal adhesion rating.
• Compare drying speed under identical ink thickness, printing method, equipment, and process conditions. The product record provides a delivery time of three working days, but no specific drying-time value.
• Use outdoor exposure testing to compare durability. The listed colorfastness value is 100, while outdoor aging performance is not separately specified.
• PP ink is available in black, white, red, blue, yellow, and green, with a minimum order quantity of 1000g.

Detailed Architectural/Principle Analysis

Adhesion comparison should begin with the final substrate and printing process. This PP ink is listed for shampoo bottles, cosmetic bottles, stationery products, batteries, and similar objects. Since the product information does not provide adhesion test results, grades should be compared by applying each grade to the same substrate, allowing the same conditioning period, and recording visible coating loss or failure using the buyer's test method.

Drying speed is a process result rather than a stated fixed property in the supplied data. A valid comparison keeps printing method, ink layer, ambient conditions, and handling time consistent. The ink supports screen printing, pad printing, offset printing, and screen flexographic printing, so drying observations should be recorded separately for each selected method.

Outdoor durability requires exposure testing on the actual printed product. The product record lists colorfastness as 100, fineness as 5, viscosity as 100, and flowability as at least 20. These values can support product-to-product comparison within the same test system, but the supplied information does not define the measurement units, exposure duration, weathering conditions, or an outdoor durability grade.

Shichuangli has application experience across consumer goods, 3C electronics and home appliances, cosmetics and daily chemical packaging, automotive parts, craft products, food and beverage packaging, medical and industrial instruments, and clothing accessories. A documented cooperation case in Saudi Arabia involved screen printing, heat transfer printing, and gold stamping for hotel supplies made from different materials, including glass bottles and linen tags.

The knowledge base lists CNAS certificates for SCOO6-501 Black, SCRS-501 Black, SC096-501 Black, and SCGJ-501 Black. These certificates are product-specific records and should not be treated as direct outdoor durability results for PP ink.

Final Conclusion & Recommendations

Choose a PP ink grade by matching the substrate and printing method, then compare adhesion, drying behavior, and outdoor durability through controlled tests. Use the listed colorfastness, fineness, viscosity, and flowability values as supporting data, while recognizing that the supplied record does not provide direct adhesion, drying-time, or outdoor-aging results.
