Product Introduction

Food-grade white pp woven bags are special packaging sacks made of 100% food-contact PP pellets, designed for agricultural grain, feed and food auxiliary material packaging with strict hygiene standards. Different from ordinary white woven bags added with optical brighteners, this product completely abandons whitening additives, retaining the natural primary color of polypropylene, which looks slightly warm yellow compared with high-bright white bags. The whole production adopts odor-free pure raw materials, no chemical peculiar smell, fully complying with food contact safety requirements. The complete production workflow includes food-grade particle melting, environmental-friendly flat yarn drawing, precision circular weaving, cold cutting and reinforced edge stitching, combining safe hygiene and stable load-bearing performance. Multiple width sizes are available to fit different loading volumes, and customized printing without harmful ink is supported for marking product specifications.

Features & Advantages

Safe Raw Material Formula Without Whitening Agent

No fluorescent whitening powder or chemical brightener is added during production. The bag shows the natural original color of pure PP raw material, presenting a faint yellow tone rather than dazzling bright white. All raw materials pass food contact safety testing, no irritating volatile substances, the bag stays tasteless during filling and storage, and will not cause secondary pollution to grain and food materials.

Reliable Structural Performance for Food Storage

Uniform PP flat yarns are woven with balanced warp and weft density, delivering outstanding tensile and anti-tearing performance. Tight weave structure blocks fine grain dust and small particle leakage during transportation. Double-layer stitching on bag bottom effectively avoids breakage under heavy stacking, while locked bag edges prevent loose threads from mixing into contents.

Specialized Hygienic Packaging Scenarios

It is widely used for packaging rice, wheat, corn, vegetable seeds and organic fertilizer in agriculture; feed factories for grain feed and microbial feed raw materials; food processing workshops for non-direct-contact food auxiliary raw materials. Its odor-free and safe property meets food circulation standards, ideal for merchants that prioritize packaging hygiene and avoid chemical additives.

FAQ

Q: Will there be color variation in the printing?

A: Due to the absorbent nature of the woven fabric surface and light reflection, a slight color deviation within 10% is considered standard industry practice. If you have extremely strict color requirements (e.g., specific brand VI colors), we strongly recommend providing a Pantone (PMS) code or approving a physical sample before mass production.

Q: What is your Minimum Order Quantity (MOQ) for custom bags?

A: The standard MOQ for custom printed bags is typically 10,000 pieces. For plain (unprinted) bags or tubular cut-and-sew bags, we can accept orders starting from 5,000 pieces.

Q: What is the lead time from order placement to delivery?

A: Stock items can be shipped within 3-5 days. For customized orders, the lead time is typically 7-15 business days, which includes both plate making and production cycles.

Q: Can I provide my own design? What are the requirements?

A: Yes, we accept vector files in AI, CDR, or high-resolution PSD format. The resolution must be above 300 dpi, and all fonts must be converted to outlines (curves). If you do not have a design file, we offer complimentary basic layout services.
