The heaviest loads,
handled by the strongest structure

PE/PP Woven Bags and Composite Bag Materials | Laminated Kraft Paper Composites & Three-Ply Kraft Paper

When standard kraft paper bags aren't strong enough, composite bags are the answer. Jiahuang's PE/PP woven bags laminate kraft paper to woven fabric, delivering far greater tear strength than plain paper bags — making them the top choice for heavy-duty loads and export shipping.

Composite Bags

PE/PP Woven Bags, Built for Extreme Conditions

Some packaging scenarios are simply beyond what plain kraft paper bags can handle: heavy loads, rough handling, ocean freight, and long-term outdoor storage. These conditions demand far greater tear resistance and weather durability.

Jiahuang's PE/PP woven bags use a composite structure of kraft paper laminated to PE/PP woven fabric — the outer kraft paper layer provides a printable, high-quality surface, the middle lamination layer offers moisture protection, and the inner PE/PP woven fabric delivers exceptional tear strength. Together, these three layers create a durability far beyond plain paper bags.

This is exactly where Jiahuang's integrated capabilities shine: lamination is an in-house process, so the quality of composite bag bonding is fully under our own control.

Product Lineup

Composite Bag Materials Products

Two composite structures designed for different strength and appearance requirements.

CB · 01

PE/PP Woven Bags

Composite bags made by laminating recycled kraft paper to PE/PP woven fabric offer the highest tear strength, ideal for heavy-duty loads, export shipping, and rough handling environments. The outer layer supports 4-color printing, balancing strength with brand presentation.

CB · 02

Three-Ply Kraft Paper

The 3-layer composite structure of recycled kraft paper laminated to woven fabric balances strength, moisture resistance, and cost — ideal for applications that need more durability than plain paper bags but don't require the highest specifications.

FAQ

PE/PP Woven Bags FAQ

What's the difference between PE/PP woven bags and regular kraft paper bags? Which should I choose?

PE/PP woven bags feature an inner layer of PE/PP woven fabric, offering far greater tear strength than plain kraft paper bags — ideal for heavy-duty loads, export shipping, or rough handling. If your contents are heavy or shipping conditions are demanding, PE/PP woven bags are recommended; for general indoor warehouse storage of heavy items, heavy-duty kraft paper bags are usually more economical.

What is the difference between three-in-one kraft paper and PE/PP woven bags?

Both are composite structures. 3-in-1 kraft paper balances strength, moisture resistance, and cost, making it suitable for applications that need more durability than plain paper bags but don't require the highest specifications. PE/PP woven bags are designed for maximum tear strength. Choose based on your budget and strength requirements.

Can the outer layer of composite bag materials be printed?

Yes. The outer layer of composite bags is kraft paper, which supports 4-color printing for brand logos and designs — combining structural strength with strong brand presentation.

Is the lamination layer produced by Chia Huang?

Yes. Lamination is an in-house capability at Jiahuang, so the quality of composite bag bonding is fully controlled by us without outsourcing, ensuring more consistent quality and lead times. See Lamination Processing for details.
