Custom Folding Carton for Premium Tea Packaging with Window and Gold Foil

The Custom Folding Carton for Premium Tea Packaging is engineered for tea brands that demand both shelf appeal and product protection. Manufactured by Guangdong Bincai Color Printing Co., Ltd. in their 18,000 sqm Foshan facility, this carton combines offset CMYK printing on KBA Rapida 105 and Heidelberg Speedmaster CD 102 7+1 UV presses with hot gold foil stamping on Bobst equipment — delivering the rich, tactile finish that premium tea packaging requires. The die-cut front window with PLA film lets consumers see the tea leaves or sachets inside, while the auto-lock bottom ensures quick assembly and secure product retention during shipping.

With 22 years of folding carton manufacturing, ISO 9001:2015 certification, and FSC Chain-of-Custody, Bincai produces tea packaging that meets the quality expectations of specialty tea retailers, e-commerce DTC brands, and international distributors alike.

FAQ

Q: Can the window film be compostable?

A: Yes — we offer PLA (polylactic acid) window film that is industrially compostable to EN 13432. For brands requiring crystal-clear clarity with recyclability, PET is also available. Both options meet food-contact safety standards.

Q: What’s the minimum order for gold foil stamping?

A: Gold foil stamping is included in the standard MOQ of 1,000 units. There’s no additional MOQ for foil — the one-time die cost covers your design, and foil color changes between production runs incur no extra charge.

Q: How well does the auto-lock bottom hold tea tins?

A: The auto-lock bottom is engineered to hold 3× the product weight — a 100g tea tin (~150g filled) is well within specification. For heavier products, we reinforce the bottom with an additional board layer or switch to crash-lock construction.

Q: Can I print on the inside of the carton?

A: Yes — using C2S (coated two sides) board, we can print brand messaging, brewing instructions, or ingredient information on the inside panels. This adds a premium unboxing detail at minimal additional cost.

Q: What’s the turnaround time for a new tea carton design?

A: Digital proofs within 24 hours, physical samples in 5–7 working days, and production delivery in 10–14 working days after sample approval. For rush orders, we can compress the timeline to 7–10 working days with an expedite fee.
