Chemical bags could be made of polypropylene woven fabric only, but for those chemical material which needs to be stored or transported under dry and leakage-proof conditions, Kraft paper laminated woven pp bags would be a more suitable packaging material choice.
PP woven bags are widely used in the packaging industry because of their low price and good tear resistance. However, it is not moisture-proof, and it has the disadvantage of being easy to leak powdery substances. Kraft paper has the characteristics of non-toxic, easy to print and moisture-proof, making it one of the long-established and widely used packaging materials, but the kraft paper bag has poor barrier properties and low mechanical strength. The combination of kraft paper and PP woven fabric can give full play to the advantages of both, and offer a moisture-proof and strong material which is suitable for packaging various solid and powdery substances.
1.Advantages of poly paper bags
Possibly to stack high with anti skid surface.

Gusseted Bags gives a box type look to bags.
Stronger & Stiffer.
Features optional with, back-seam or tubular type, perforation, LDPE/HDPE liner inserted, E-Z Open, Flexographic printing up to 6 colors, bag body and gussets printing available. Stitched or hot melt seal bottom optionally. Paper choices as, Brown kraft paper or white kraft paper laminated with PP woven fabric available in different colors. Thickness of paper and woven polypropylene are customized upon specific applications.
3.Performance requirements for poly paper bags
1. Fastness: The tensile and impact strength of the bag can withstand the pressure in gravity, stacking and impact during transportation.
2, Sealing: due to the different packaging materials of paper-plastic composite packaging, each has different sealing requirements. In particular, the sealing performance of powder or toxic materials and materials that are afraid of being contaminated is very strict.
3, Anti-mildew properties: materials that are prone to moisture or mildew have special requirements for the airtightness of packaging materials.
4. Environmental protection requirements: The packaging bag must be degradable and recyclable materials to alleviate environmental pollution.
5, assembly and disassembly performance: modern large-scale industrial production will inevitably require high efficiency, large bag packaging is mostly raw materials or primary processing products, so paper-plastic composite packaging bags also need to meet the requirements of easy to open, easy to dump.
