Frequently Asked Questions

Can square bottom paper bags support custom brand printing?

Yes, flexo and offset printing are available. Multiple color options are supported on kraft or white paper to display logos, contact data and brand patterns for retail promotion.
We supply greaseproof coated square bottom paper bags. The inner barrier layer stops oil penetration, safe for bread, fried snacks and other food takeaway scenarios.
Width, height and bottom depth can be adjusted according to demands. Standard and oversized specifications are available for groceries, clothing and gift packaging scenarios.
Twisted paper handles and flat paper handles are optional attachments. Handles can be automatically bonded during production to improve customer carrying experience.
