FAQ

What content does the Knowledge Base mainly share?

The LeXiang Knowledge Base mainly shares professional knowledge about packaging boxes, premium gift boxes, self-adhesive labels, anti-counterfeit labels, QR code labels, small-batch packaging, and digital printing. It also covers packaging processes, industry applications, and packaging customization experience, helping brands understand packaging trends and solve practical problems.

What is small-batch packaging?

Small-batch packaging means producing packaging with a low minimum order quantity, typically starting from dozens to a few hundred units. Using digital printing technology, no plate-making is required, enabling rapid sampling, multi-SKU production, and personalized customization. It is especially suitable for new product trials, seasonal promotions, and brand upgrades.

What is the difference between digital printing and traditional printing?

Digital printing requires no plate-making and offers advantages such as low minimum orders, fast delivery, and variable data printing support, making it ideal for small-batch and personalized packaging. Traditional printing requires plate-making and is better suited for large-volume production. More and more brands are choosing digital printing to reduce inventory risk and improve market responsiveness.

Do labels support QR code and anti-counterfeiting functions?

Yes. LeXiang provides QR code labels, anti-counterfeit labels, and variable data labels, supporting one-code-per-item, anti-counterfeit traceability, anti-diversion, and marketing interaction applications, helping brands improve product management efficiency and consumer experience.

Can packaging boxes and labels be customized together?

Yes. LeXiang offers one-stop customization services for both packaging boxes and labels. Customers can simultaneously order premium gift boxes, food packaging boxes, self-adhesive labels, anti-counterfeit labels, and QR code labels. Unified design and production management enhance brand image and procurement efficiency.
