“To many people packaging is just a bag. To us it is a craft — bags are all we make, and we make them properly.”

Paper-Plastic Composite Kraft Paper Bag
A three-in-one composite sack built on a PP woven fabric core, laminated with a cast film and faced with refined kraft paper. The structure combines the tensile strength of a woven bag with the print quality and moisture barrier of a paper sack — the standard export packaging for cement, tile adhesive, putty powder, mortar, chemical granules and mineral powders.
Supplied by Wenzhou Huishen Plastic Industry Co., Ltd., a manufacturer with 15 years of experience, 20,000 m² of workshop space and a daily output of 500,000 bags. Sizes, fabric weight, printing and lamination are all made to order.
- ✔ Moisture-proof — film layer blocks humidity in sea freight and storage
- ✔ High burst strength — square-bottom construction stacks neatly and resists tearing
- ✔ Print-ready kraft surface — gravure printing with customer artwork
- ✔ Valve or open mouth — compatible with automatic filling lines
