Coding on HDPE Bags
Dates, weights and batch codes on HDPE and woven bags of fertilizer, animal feed, flour, sugar, rice and grain.
Readable codes on a rough, dusty, heavy-duty sack
HDPE and woven bags carry some of the heaviest and most important products in Kenya: fertilizer, animal feed, maize flour, sugar, rice and grain. The surface is textured, bags are often dusty, and they are filled, closed and stacked at speed, so codes must be large, clear and well placed.
Continuous inkjet and drop on demand printers mark these bags without contact, using inks chosen to grip woven and laminated surfaces. Position matters: we plan where the code sits in relation to the weave, the seam and the closure so it stays readable on the stack.
What we code on bags
- Production and expiry dates
- Batch and lot numbers
- Net weight and grade
- Product names and brand text
- Barcodes and QR codes
Key features
What you can expect from a coding system set up for this pack.
- Inks for woven surfacesInks that grip woven and laminated bag surfaces resist rubbing in handling and storage.
- Large, clear charactersMarks big enough to read across a stack in a warehouse or on a truck.
- Dust-aware setupHead position and cleaning routines planned around flour, feed and fertilizer dust.
- Filling-line speedNon-contact printing keeps pace with the bagging line.
Built for Kenyan production lines
Millers, fertilizer blenders, feed makers and sugar packers in Kenya fill and move bags in volume, in dusty plants and warehouses, and bags often change hands several times before reaching the farm or shop.
- Codes planned for dust from flour, feed and fertilizer.
- Marks readable across a stack in a warehouse or on a loaded truck.
- Batch and date codes that help trace a bag back to the plant if a query comes up.
- Local inks, spares and fault response, with maintenance plans.
- Operator training so message changes between products and bag sizes are quick.

Common questions
Can you code on woven bags?
Yes. With the right ink and print head position, codes can be applied to woven and laminated surfaces. We confirm this against your bag before recommending a system.
Will dust affect the printer?
Dust is a real factor in flour, feed and fertilizer plants. We plan the head position, cleaning routine and maintenance around it.
Can the code go on the bag closure?
Often, yes, depending on the closure type and the space available. We assess this on your line.
