Frequently Asked Questions (FAQ)
Q1: What is the primary benefit of adding Calcium Carbonate (CaCO3) to PP?
A: Adding CaCO3 increases the density and stiffness of the board, providing higher crush resistance and superior flatness. It also reduces plastic content, making the packaging more eco-friendly and easier to print on.
Q2: Is this packaging suitable for food contact?
A: Yes, our boxes use non-toxic PP materials and exclusive eco-friendly water-based inks, making them safe for agricultural products, seafood, and various food logistics.
Q3: How many times can these boxes be reused?
A: These boxes are designed for high durability and can typically be reused for over 50 cycles, significantly reducing the "cost per trip" compared to traditional cardboard.
Q4: Can the boxes withstand extreme cold for frozen goods?
A: Absolutely. They are 100% waterproof and perform reliably in cold chain environments as low as -20°C without becoming brittle.
Q5: What customization options are available for branding?
A: We offer full-color high-definition printing (5-color+), silk-screen printing, and custom color matching (Pantone/CMYK) to transform shipping boxes into premium branding tools.
Q6: Are the materials used in the boxes recyclable?
