FAQ & Buying Guide
Q: What is the PP board base, and what does it do?
A: Each bag includes an attached polypropylene (PP) board at the bottom that provides rigidity and prevents the bag from deforming during use. The reinforced base keeps the bag standing upright and stable, even when partially loaded.
Q: Is the sublimation printing really on all 6 sides?
A: Yes. This 3D-structured design allows full-color CMYK sublimation printing on all six outer surfaces — front, back, left side, right side, bottom, and lid. This provides 360-degree brand visibility.
Q: How does the lid closure work?
A: The bag features a zippered lid on top that opens fully for easy loading and closes securely to maintain insulation and protect contents during transport.
Q: Is this bag suitable as a premium promotional gift?
A: Absolutely. The structured 3D design, PP board base, 6-side printing, and insulated lining give this bag a premium look and feel that stands out from standard flat cooler bags — making it ideal for high-value corporate gifting and VIP giveaways.
Q: Where is this bag manufactured?
A: 100% manufactured in Taiwan with quality control from sublimation printing through PP board assembly and final inspection.
