Household & Consumer Products

Suitable for household products, plastic toys, storage products, and other consumer plastic products. Household and consumer products typically require consistent color, an attractive surface appearance, and reliable batch-to-batch consistency. Polytech provides white, color, and functional masterbatch solutions tailored to the product material, target color, opacity requirements, and processing method, helping reduce issues such as color streaks, flow marks, color spots, poor dispersion, and uneven surface color.

01Coordination & Consistency

Storage boxes, laundry baskets and other household products often need coordinated colors across parts. Differences in resin, wall thickness and surface texture can affect the final appearance. Matching the masterbatch in the actual production material helps achieve a closer match between components.

02Dispersion & Uniformity

Large molded surfaces make color streaks and specks easy to see. A masterbatch with good pigment dispersion and a carrier suited to the base resin helps produce more uniform color. Dosing, mixing and molding conditions also need checking when surface defects appear.

03Consistency & Batches

Keeping the same shade across production batches can be difficult. Consistent masterbatch quality and accurate dosing help control variation, while repeat trials confirm that the formulation works under normal production conditions. Retain an approved molded sample as the reference for subsequent batches.

Representative Case Study

Eliminate color streaks and ensure uniform appearance in large PP storage boxes with our high-dispersion color masterbatch, optimized for consistent dosing and molding performance.

Challenge

A gray PP storage box showed visible color streaks across its large side panels. Its overall shade was close to the approved sample, but the uneven appearance did not meet the customer's requirements.
Solution

Check dosing, mixing and molding conditions, then trial a color masterbatch with good dispersion and a carrier suited to PP. Compare color and surface uniformity using the same resin grade, mold and processing conditions.
Expected Outcome

Reduce visible color streaks and meet the agreed color requirements, with appearance and impact performance confirmed through repeat production trials.
