Food Packaging PP Sack Printing Ink — Chemi Series | Bangladesh

Machine Specification

Food-grade vs agro-grade PP sack ink — the difference

Both agro-grade (Chemi PP Sack) and food-grade (this series) inks stick to woven PP and hold colour outdoors. The critical difference is chemical compliance: food-grade ink is formulated to meet migration and contact-safety limits so that any trace ink migration into the packaged food stays within regulated limits. Agro-grade ink prioritises adhesion and UV stability but is not tested for food-contact migration.

For rice mills, flour mills, sugar packers and specialty dry-food packagers in Bangladesh, using the food-grade PP Sack ink is either a buyer requirement (for branded retail rice, export rice under buyer contracts) or a regulatory prudence (for products where direct ink-to-food contact through the woven PP is possible). It costs slightly more per drum but the compliance and buyer-approval advantage justifies it.

Applications

Bangladesh customers are rice mills and packers (both government procurement rice and branded retail rice), flour and sugar packers, pulse and dry-food packagers (dal, chickpeas, spice pre-packs) and specialty food-grade PP sack applications. The category has a stable, high-volume demand — rice packaging alone consumes millions of PP sacks per year across Bangladesh.

For rice mills and food packagers producing under retail brand contracts or export contracts, the food-grade ink simplifies buyer compliance and reduces the risk of shipment rejection over ink-migration concerns — a documented risk with generic-brand PP sack inks that lack food-contact testing.

Frequently Asked Questions

How is this different from Chemi PP Sack (agro-grade)?

Same substrate compatibility (woven PP) but this food-grade version meets migration compliance for direct food-contact packaging. The agro-grade version does not carry food-contact compliance — use it for fertiliser, feed and non-food agro applications only.

Is it certified for direct food contact?

Yes — Chemi PP Sack food-grade meets standard food-contact migration limits for the packaged-food categories it is designed for (rice, flour, sugar, dry-food bulk). Compliance documents supplied on request.

Will it adhere to any woven PP sack, or only food-grade coated versions?

Adheres to standard woven PP without any special coating. Both plain woven PP and BOPP-laminated food-grade sacks accept the ink well.

How long does colour last on outdoor-stored food sacks?

Typically 6–12 months of outdoor exposure without significant fade, comparable to the agro-grade version. Under indoor or shaded storage, colour lasts significantly longer.

What container sizes are stocked?

Standard 25kg drums for volume users, plus 5kg pails for smaller print operations. Bulk drums on order for high-volume rice mills and food packagers.

What is the delivery time in Bangladesh?

Standard colours ship from Dhaka stock within 3–7 days. Custom brand-specification colours from Chemicoat take 30–45 days.
