Working with us
A bag supplier who answers technical questions
Most packaging problems are decided before the first bag is sewn: the wrong fabric weight, a closure that jams your filling line, a liner that lets moisture through, printing that rubs off in transit. We start from your product and your equipment, not from a catalogue page.

- Material and closure recommendation with the reason why
- Digital proof and pre-production sample before mass production
- In-line and final inspection with a traceable quality record
- Baled or palletized packing, container loading photos before shipment
- One English speaking sales contact from inquiry to delivery
