White packaging has to look clean, block light when needed, and stay suitable for food. The right food-grade white masterbatch helps you reach all three goals without slowing down your line.
Debao is a white masterbatch manufacturer China buyers can work with directly. Our plant is in Jiangyin, Jiangsu, and we focus on one product family: white masterbatch for PE, PP, PET, PS and ABS. This guide explains how food-grade white masterbatch for packaging works, which grade fits your process, and what to check before you order. It is written for importers, distributors, brand owners and procurement teams who compare suppliers before they send an inquiry.
"Food-grade" means the formulation is designed for packaging that may touch or sit near food. The pigment, carrier resin and additives must suit that use. The finished package must also meet the rules of the country where you sell it.
Packaging makers use masterbatch instead of raw pigment for three practical reasons:
• Cleaner handling, with no loose pigment dust in the workshop
• More even color and opacity from batch to batch
• Simple dosing and faster color changes on the line
• Single-product focus: white masterbatch only, with pigment loading from 20% to 75%
• Wide resin range: PE, PP, PET, PS and ABS carriers
• Modern production: advanced equipment, a professional R&D team and strict quality control
• Export awareness: we exhibited at K 2025 in Düsseldorf and Chinaplas 2025 and serve buyers in many regions
• Direct supply: you deal with the manufacturer, which helps with pricing, lead time and technical support
We also supply ABS white masterbatch. ABS is mainly used for appliances and electronics, so it is not a typical choice for food packaging.
• High opacity: helps hide the product and protect light-sensitive food
• Consistent whiteness: supports brand color standards across repeat orders
• Stable processing: runs smoothly on film, injection and blow molding lines
• Low dust pellets: easier and cleaner to handle than powder pigment
• Custom options: pigment loading, carrier resin and melt flow can be adjusted to your process
Melt flow index tip: choose a masterbatch carrier with an MFI equal to or slightly higher than your base resin. This helps the pigment disperse evenly. A poor match can cause streaks, gels or unstable film thickness.
• A declaration of compliance for your target market, such as EU rules for plastic food contact materials or US FDA requirements
• Raw material statements for the pigment and carrier resin
• RoHS or REACH statements if your customer requires them
• Guidance on migration testing of your finished package
The company that makes the final package must test and confirm that the finished article meets local rules. A masterbatch declaration supports that work, but it does not replace it.
You can review our compliance information on the Regulatory page. Tell us your target country and resin, and we will confirm which documents are available for your grade.
• Food bags and pouches: bread bags, frozen food bags and snack packaging
• Films: stretch film, shrink film and lamination layers
• Bottles: dairy, beverage and sauce bottles that need light protection
• Trays and containers: thermoformed trays, boxes and takeaway containers
• Cups, lids and closures: injection molded PP and PS parts
Debao white masterbatch also serves industrial packaging, consumer goods, agriculture, infrastructure and hygiene products. This wider experience helps us support mixed-product buyers.
Do not judge by color alone. Test opacity at your real thickness, and compare whiteness with your current material. Ask for a sample, run it on your line, and measure the result.
Use this simple checklist when you compare suppliers:
1. Confirm your base resin. Match PE to PE, PP to PP, and PET to PET. This is also the first step when you choose white masterbatch for PET or PE.
2. Define your market. Your target country sets the compliance documents you need.
3. Set opacity and whiteness targets. Note your film thickness or wall thickness.
4. Check your process. Film, injection and blow molding need different flow and dispersion.
5. Request a sample and run a trial. Test dispersion, opacity, odor and line stability.
6. Review supplier proof. Ask about factory information, batch consistency, lead time and technical support.
Dosage (%) = Target TiO₂ in the final product ÷ TiO₂ in the masterbatch × 100
Example: you want 4% TiO₂ in a film, and your masterbatch contains 50% TiO₂. The dosage is 4 ÷ 50 × 100 = 8%. This is only an estimate. Always confirm by trial.
• Start with a ladder trial at several dosage levels and compare opacity
• Use accurate dosing equipment so color stays even over a long run
• Dry PET and other moisture-sensitive resins before processing
• Avoid overloading. Too much pigment can affect strength and surface quality
Please ask our team about the test items and quality documents available for your order. We can also discuss retained samples for repeat orders, so you can compare batches over time.
• Your base resin type and grade
• Your process: film, injection molding, blow molding or thermoforming
• Film thickness or part design
• Target opacity, whiteness and any color reference
• Your target market and compliance needs
Our team will suggest a pigment loading, carrier resin and melt flow range, then arrange sample production for your trial.
For long-term cooperation, we can also discuss regular shipment plans, so you can keep stock levels steady and plan production with confidence.

What Is Food-Grade White Masterbatch for Packaging?
Food-grade white masterbatch is a pellet concentrate. It contains white pigment, mainly titanium dioxide (TiO₂), dispersed in a carrier resin. You add a small amount to natural plastic during extrusion or molding. The result is a uniform white film, bottle or container."Food-grade" means the formulation is designed for packaging that may touch or sit near food. The pigment, carrier resin and additives must suit that use. The finished package must also meet the rules of the country where you sell it.

Food-Grade White Masterbatch Types: PE, PP, PET and PS
The carrier resin decides where a masterbatch works best. Always match it to your base polymer. Below are the main options for packaging.PE White Masterbatch
PE is the most common choice for food bags, liners, stretch film and squeeze bottles. Our PE White Masterbatch is designed for PE film extrusion and molded PE parts, where smooth dispersion and stable output matter.PP White Masterbatch
PP suits food boxes, cups, lids, caps and PP film. Our PP White Masterbatch fits injection molding and film lines, with grades selected by melt flow index.PET White Masterbatch
PET white masterbatch is used for bottles and sheet, such as dairy and beverage packaging that needs light protection. PET needs careful drying, so confirm your process with our team before a trial.PS White Masterbatch
PS masterbatch for thermoforming is common in yogurt cups, trays and disposable food containers. White color gives a clean look and good print contrast.We also supply ABS white masterbatch. ABS is mainly used for appliances and electronics, so it is not a typical choice for food packaging.
Key Features and Benefits for Food Packaging
• High TiO₂ dispersion: reduces streaks, specks and weak spots in thin film• High opacity: helps hide the product and protect light-sensitive food
• Consistent whiteness: supports brand color standards across repeat orders
• Stable processing: runs smoothly on film, injection and blow molding lines
• Low dust pellets: easier and cleaner to handle than powder pigment
• Custom options: pigment loading, carrier resin and melt flow can be adjusted to your process
Technical Specifications: TiO₂ Content (20%-75%), Carrier Resin and Melt Flow Index
Exact data depends on the grade. The table below shows the points buyers ask about most. Please request the technical data sheet for the grade you plan to use.| Parameter | Typical Range / Option | Why It Matters |
| TiO₂ (pigment) content | 20% to 75% | Higher loading gives strong opacity at a lower dosage. |
| Carrier resin | PE, PP, PET, PS, ABS | The carrier must match your base polymer for even mixing. |
| Melt flow index (MFI) | Matched to your base resin; low-MFI grades available on request | A close MFI match improves dispersion and reduces defects. |
| Main packaging uses | Films, bags, bottles, trays, cups, closures | Each process needs a different carrier and dispersion level. |
| Dosage (let-down ratio) | Confirmed by trial run | Sets final opacity, whiteness and cost per kg of packaging. |
| Compliance documents | Declarations by grade and market, on request | Needed for your own food contact assessment. |
| Customization | Pigment loading, carrier, MFI, packing | Lets you match your film thickness and process. |
Melt flow index tip: choose a masterbatch carrier with an MFI equal to or slightly higher than your base resin. This helps the pigment disperse evenly. A poor match can cause streaks, gels or unstable film thickness.
Food Contact Compliance and Safety Standards
Compliance is the first question most food packaging buyers ask. Treat it as a document check, not a marketing slogan. Before you buy any food-grade white masterbatch, ask your supplier for:• A declaration of compliance for your target market, such as EU rules for plastic food contact materials or US FDA requirements
• Raw material statements for the pigment and carrier resin
• RoHS or REACH statements if your customer requires them
• Guidance on migration testing of your finished package
The company that makes the final package must test and confirm that the finished article meets local rules. A masterbatch declaration supports that work, but it does not replace it.
You can review our compliance information on the Regulatory page. Tell us your target country and resin, and we will confirm which documents are available for your grade.
Applications: Food Bags, Films, Bottles, Trays and Containers
White masterbatch is used wherever packaging needs a clean, opaque look. Typical uses include:• Food bags and pouches: bread bags, frozen food bags and snack packaging
• Films: stretch film, shrink film and lamination layers
• Bottles: dairy, beverage and sauce bottles that need light protection
• Trays and containers: thermoformed trays, boxes and takeaway containers
• Cups, lids and closures: injection molded PP and PS parts
Debao white masterbatch also serves industrial packaging, consumer goods, agriculture, infrastructure and hygiene products. This wider experience helps us support mixed-product buyers.
Food-Grade White Masterbatch for Film, Injection Molding and Blow Molding
Film extrusion
Thin film shows every dispersion problem. Look for a high-dispersion white masterbatch that keeps filter pressure stable and avoids die build-up. This matters most for white masterbatch for plastic bags and thin packaging film.Injection molding
For white masterbatch for injection molding, match the melt flow index to your resin and check color consistency between batches. Good flow helps fill thin walls, such as lids and cups, without flow marks.Blow molding
For white masterbatch for blow molding, opacity and wall thickness work together. A bottle with thin walls needs higher pigment loading to block light. Run a trial at your real wall thickness before you confirm a grade.High Opacity and Whiteness for Food Packaging
Opacity depends on three things: TiO₂ content, dispersion quality and part thickness. If one is weak, the other two must work harder. High opacity white masterbatch for packaging gives you more room to reduce film thickness or dosage.Do not judge by color alone. Test opacity at your real thickness, and compare whiteness with your current material. Ask for a sample, run it on your line, and measure the result.
How to Choose the Right Food-Grade White Masterbatch
Use this simple checklist when you compare suppliers:
1. Confirm your base resin. Match PE to PE, PP to PP, and PET to PET. This is also the first step when you choose white masterbatch for PET or PE.
2. Define your market. Your target country sets the compliance documents you need.
3. Set opacity and whiteness targets. Note your film thickness or wall thickness.
4. Check your process. Film, injection and blow molding need different flow and dispersion.
5. Request a sample and run a trial. Test dispersion, opacity, odor and line stability.
6. Review supplier proof. Ask about factory information, batch consistency, lead time and technical support.
Recommended Dosage (Let-Down Ratio) and Processing Guide
The let-down ratio is the share of masterbatch you add to the base resin. Use this formula to estimate it:Dosage (%) = Target TiO₂ in the final product ÷ TiO₂ in the masterbatch × 100
Example: you want 4% TiO₂ in a film, and your masterbatch contains 50% TiO₂. The dosage is 4 ÷ 50 × 100 = 8%. This is only an estimate. Always confirm by trial.
• Start with a ladder trial at several dosage levels and compare opacity
• Use accurate dosing equipment so color stays even over a long run
• Dry PET and other moisture-sensitive resins before processing
• Avoid overloading. Too much pigment can affect strength and surface quality
