Corrugated Shipping Cartons: Board, Structure and Factory Production
UGI Packaging manufactures 9 distinct corrugated carton structures at its Guangzhou factory — from single-wall kraft mailers to 7-layer heavy-duty export cartons — with full-color litho-laminated printing, 8 surface finish options, and a 5-stage ISO 9001 quality control process. No fixed MOQ. Samples in 7 days.
UGI Packaging manufactures corrugated shipping cartons and mailers in our factory through board conversion, printing, die cutting, slotting, creasing, folding, gluing or stitching, assembly and QC. A shipping carton must be designed around the packed product, route, stacking pattern and handling conditions rather than selected from outside dimensions alone.
Mailer and retail-shipping structures
Self-locking mailers can reduce tape and improve presentation, while regular slotted cartons suit many master-carton applications. Small items still need restraint so they cannot move, strike edges or concentrate load on unsupported panels.

Heavy-duty and kraft carton decisions
Board descriptions such as three-layer or thickened are incomplete without flute, liner, medium and performance requirements. Long cartons and flat packs need particular attention to panel span, bending and closure.

Custom branding and dimensions

Testing, quotation and QC
Distribution validation should use the complete packed system. ISTA test procedures offer recognized options for parcel and distribution testing, but the project must define the selected procedure and pass criteria.
Send product dimensions and weight, carton dimensions, board requirement, inserts, closure, printing, quantity, pallet or parcel method and destination. Our QC checks board identity, dimensions, slots, scores, glue or stitch, print, closure, packing count and specified performance tests.
