A Packaging Bag Factory Built on Consistency
Established in 2014 in Longgang, Zhejiang, Ronggao Packaging is a custom packaging and printing manufacturer with a team of more than 100 people.
Growing in China’s Packaging Industry Cluster
Longgang Ronggao Packaging Co., Ltd. was established on November 28, 2014 in Longgang, Wenzhou — one of China’s established printing and packaging industry clusters. We focus on custom packaging and printing, including packaging boxes, paper carrier bags, non-woven bags, insulated bags, PVC bags and other made-to-order packaging products.
Today our team of more than 100 people serves medium and large enterprises in China and overseas. Projects are developed around each buyer’s structure, material, print artwork, finishing, packing and delivery requirements.
What has never changed is our way of working: honest pricing, fast replies, and problems solved before they reach the customer.
In-House Capability, End to End
No outsourcing means no surprises. Every process from printing to packing happens on our floor.
Printing
2× 8-color flexo presses, 1× 4-color Heidelberg offset press, silk-screen and heat-transfer lines.
Weaving & Film
PP tape extrusion and circular looms for woven fabric, blown-film lines for PE, and paper-plastic lamination machines.
Converting
Automatic bag-making machines, sewing lines, die-cutters, foil stampers and embossing equipment.
Quality Lab
GSM meters, film thickness gauges, bursting and drop-test rigs, handle pull testers and color-difference meters.
On the Sewing Floor
Canvas, non-woven and fabric bags are sewn on dedicated lines, with in-process checks at every station.
Standardized QC from Raw Material to Finished Bag
Every bag ships dimension-accurate, print-crisp and load-reliable — whatever the material.
1 · Raw Material Sourcing
Every paper, resin and fabric lot is checked on arrival — GSM, moisture content, tensile strength — before it enters the warehouse.
2 · Production Control
Print registration, film gauge, seam strength and stitching density are monitored in-line by dedicated QC staff on every shift.
3 · Finished Product Inspection
Dimensions, print clarity and load reliability are verified with AQL sampling and drop tests before any order ships.
Whether you need beautiful retail totes, eco-friendly paper carriers, insulated cooler bags or custom PVC totes, the same standardized process stands behind every product.
