Q1: What is the primary function of Infilm300 in polymer films?
A: Infilm300 is a functional mineral pigment designed to enhance optical properties—particularly opacity and light diffusion—in thin polymeric films, while maintaining good dispersion and processability during extrusion or casting.
Q2: Is Infilm300 suitable for food-contact packaging applications?
A: Infilm300 is manufactured under strict quality control and is commonly used in food-contact compliant formulations; however, final regulatory acceptance depends on the complete formulation, processing conditions, and applicable regional requirements—end users must validate compliance through their own regulatory assessment.
Q3: How does Infilm300 compare to conventional calcium carbonate or titanium dioxide in film applications?
A: Unlike standard calcium carbonate, Infilm300 offers optimized particle morphology and surface treatment for improved dispersion in low-viscosity melts. Compared to titanium dioxide, it provides a more cost-effective opacity solution with lower refractive index contrast—making it ideal for applications where high hiding power is not required but uniform diffusion and haze control are critical.
Q4: What processing methods is Infilm300 compatible with?
A: Infilm300 is engineered for compatibility with common thermoplastic film processes including blown film extrusion, cast film extrusion, and lamination—its surface modification supports stable feeding and minimal die buildup across typical operating temperatures for polyolefins and polyesters.
Q5: How should Infilm300 be incorporated into a film formulation?
A: It is typically introduced via masterbatch or direct addition during compounding; dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight—optimal loading should be determined through application-specific trials to balance opacity, mechanical integrity, and process stability.
