Custom Superior Adhesion Water Based Ink For Paper Cups And Plates

Food-grade eco water-based ink specially developed for food paper containers, applicable to PE coated paper cups, disposable paper plates, cake trays and milk tea cup packaging paper. Made of food-grade raw materials, it is odor-free, low VOC, heavy-metal-free, safe and compliant with food contact environmental standards. Featuring outstanding adhesion on PE coated surfaces, it forms dense, flexible ink film resistant to hot water, rubbing and scratching without fading. Fine ink with strong fluidity for high-speed flexo assembly lines without plate clogging. Fast drying without blocking and consistent batch color free of delamination or sedimentation after long storage. It is the preferred eco ink for food paper container printing.

Six advantages of water-based ink:

1. Food-Grade Eco & Odor-Free:

Made of food-contact raw materials, heavy-metal-free, low VOC and irritation-free, compliant with food packaging safety standards.

2. Superior Adhesion on PE Coated Paper:

Formulated for PE coated cup surfaces with strong adhesion free of ink peeling, perfectly fit for all coated paper container printing.

3. Hot Water & Abrasion Resistant Without Fading:

Dense and tough cured film resists hot water soaking and wiping without fading during stacking and transportation of hot beverage products.

4. Fine Dots & High Definition Printing:

Ultra-fine even ink with strong tinting power and transparent rendering, sharp texts & patterns with high dot reproduction for neat delicate

prints.

5. Stable On-Press Performance for High-Speed Production:

Good fluidity & low foaming without plate clogging or ink dragging during long runs, ideal for high-speed flexo lines in the paper cup industry.

6. Fast Drying Anti-Blocking with Good Stackability:

Rapid curing prevents adhesion after printing.

How to Choose

1. By Substrate:

General grade for plain base paper; high-adhesion formula mandatory for PE coated cups & paper plates to avoid ink peeling.

2. By Temperature Resistance:

Standard grade for cold drink cups; hot water & boiling resistant grade for milk tea cups and instant noodle bowls to resist discoloration under

high temperature.

3. By Printing Speed:

 Slow-drying general ink for proofing; fast-drying anti-clog anti-block grade for high-speed flexo lines to ensure continuous production.

4. By Printing Precision:

General ink for simple texts; high-concentration fine ink with superior dot reproduction for delicate color patterns.

How to use:

1.Stir thoroughly before use
Stir the whole barrel of ink evenly after opening to eliminate sediment and ensure consistent concentration.
2.Adjust viscosity
The original ink can be used directly. If it is too thick, dilute only with pure water. Do not add other solvents.
3.Printing operation
4.Suitable for flexo printing machines. Control the printing speed to form thin and even ink film without ink accumulation or smudging.
4.Machine maintenance
Keep the printing plate moist during short downtime. Clean anilox rollers and plates thoroughly for long shutdown to avoid dry blockage.
5.Storage

Tighten the lid after use, store sealed in cool dark place at room temperature to prevent crusting, delamination and deterioration.

Q1: Is this ink food-grade and safe?

Safe and compliant. Made of food-contact eco raw materials, benzene-free, heavy-metal-free, low VOC and odor-free, meeting food packaging printing standards. Applicable to disposable paper cup & plate outer packaging with export test compliance.

Q2: Can it print directly on PE coated paper cups?

Yes, specially formulated for PE coated surfaces with strong adhesion free of peeling, perfectly fit for milk tea cups, hot drink cups and coated paper plates.

Q3: Will the print fade after filling hot water?

No. Dense and flexible cured film delivers excellent hot water & boiling resistance without fading, whitening or peeling when holding hot drinks normally.

Q4: Will plate clogging or foaming occur on high-speed machines?

Good fluidity & defoaming property with fine particle size and minimal impurities. Stable long-hour high-speed flexo printing free of mesh clogging, foaming and ink dragging.

Q5: Are additives or secondary grinding required?

No grinding or additives needed. Ultra-fine finished ink ready for printing after stirring, saving process costs.

Q6: Will prints stick together after printing?

Low blocking with fast film formation. No adhesion after hot air drying on assembly lines, suitable for mass continuous production.

Q7: Are batch color differences significant with stable batches?

High-purity pigments with precise blending deliver minimal color deviation and uniform shades for large-volume printing.

Q8: Will sedimentation or deterioration occur after long storage?

Stable formula resists delamination, sedimentation and skinning under sealed storage with long shelf life. Stir well after standing to restore optimal performance.

Q9: Do you support trial samples and custom colors?

Trial samples available with standard colors in stock. Custom spot & Pantone colors supported for small and bulk orders.
