Food-Grade Masterbatch for Food Packaging
Customer Requirements
The masterbatch is specially designed for food-grade plastic packaging products, including but not limited to beverage bottles, food containers, disposable tableware, and food packaging films. It is mainly used for export-oriented food packaging projects, so it must strictly comply with the safety standards of FDA (US Food and Drug Administration) and EU 10/2011 (Regulation on Plastic Materials and Articles Intended to Come into Contact with Food).
In terms of performance, the color of the masterbatch is required to be bright, uniform and stable, without color fading, discoloration or migration during use. At the same time, it must have excellent high-temperature resistance, which can withstand the high temperature of more than 120℃ during packaging processing (such as blow molding, injection molding) and high-temperature sterilization of food products, ensuring no decomposition or release of harmful substances.
In addition, it is required to have good compatibility with base polymers (such as PP, PE, PET) and high dispersion, so as to avoid streaks, color spots and other defects on the surface of the final packaging products, and meet the high-quality requirements of food packaging appearance and safety.

Customized Solution
1. Raw Material Selection: Adopt food-grade carrier resins (PP, PE, PET) that are fully compatible with food packaging substrates, and select non-toxic, pollution-free food-grade pigments that meet FDA and EU 10/2011 standards, ensuring that the heavy metal content is lower than 1ppm and no plasticizers are detected, and the total migration amount meets the standard requirements of ≤10mg/dm².
2. Functional Additive Configuration: Add high-efficiency antioxidants and light stabilizers to the formula to effectively inhibit the oxidative degradation of the masterbatch under high temperature and UV irradiation, prevent color fading and yellowing, and ensure long-term color stability of food packaging during storage and use.
3. Process Optimization: Adopt nano-level dispersion technology to make the pigment evenly dispersed in the carrier resin, with a particle size ≤1μm, which solves the problem of uneven color and streaks in traditional masterbatches, and improves the color consistency and surface finish of packaging products.
4. Color Customization: Provide a variety of color options according to customer needs, including transparent, pure white, bright red, sky blue, lemon yellow, etc., which can be accurately matched with the brand color of food products to enhance the shelf recognition of packaging, while ensuring that all color systems meet food safety standards.

Application Results
The independently developed food-grade masterbatch has successfully passed FDA 21 CFR and EU 10/2011 certification, and also meets the relevant requirements of SGS detection and OEKO-TEX 100 certification, fully complying with the market access standards of European and American food packaging industry.
At present, the product has been successfully applied by customers in the production of export food packaging, covering beverage bottles, fast food containers, food packaging films and other products. It has excellent performance in actual use: the color is bright and uniform, the color consistency rate reaches more than 98%, and it can maintain stable color without fading after being subjected to high temperature of 130℃ for a long time, which fully meets the customer’s high-temperature resistance requirements.
In addition, the masterbatch has good compatibility with various food-grade plastic substrates, easy processing and molding, no adverse impact on the mechanical properties of packaging products, and effectively reduces the production cost of customers while ensuring safety and aesthetics. It has won high recognition and satisfaction from customers, and established a long-term and stable cooperative relationship.
