5. Frequently Asked Questions
Material Selection
What material should I choose for small batch production (<5000 pieces)?
For small batch production, we recommend using PET material because it has good molding performance and cost benefits. If extremely high transparency is required, PMMA material can be considered, but the cost will increase accordingly.
How to choose eco-friendly materials?
We recommend using recyclable PET materials or bio-based materials. Although bio-based PET has a higher cost, it meets the environmental trends of 2026 and helps enhance brand image.
Process Technology
How to solve compatibility issues with cosmetic packaging?
We conduct rigorous material compatibility tests and select appropriate packaging materials based on cosmetic ingredients. Special attention should be paid to material selection for products containing alcohol, AHA, and other ingredients.
How to improve the wear resistance of packaging?
We can improve the wear resistance of packaging by adding scratch-resistant additives, optimizing material formulas, and selecting appropriate surface treatment technologies. Our hot stamping technology can achieve more than 5000 rub resistance cycles.
Quality Control
How to ensure the sealing of packaging?
We adopt strict sealing test standards, including negative pressure testing, positive pressure testing, and leak rate testing. Our leak rate can reach <10^-6 atm·cc/s, far exceeding industry standards.
How to handle appearance defects in packaging?
We reduce appearance defects by optimizing mold design, controlling molding process parameters, and implementing strict appearance inspection standards. Our defect rate can be controlled below 0.5%.
Cost & Delivery
How long does mold development take?
The standard mold development cycle is 30-45 days. We also provide express delivery services, which can complete mold development within 20-30 days.
How to reduce packaging costs?
We can help customers reduce packaging costs by optimizing design, selecting appropriate materials, improving production efficiency, and reducing defect rates. Our solutions can typically help customers reduce packaging costs by 15-25%.
