Feed sacks live in a different warehouse than retail rice sacks. At a feed mill, sacks stack in layers to waist height or higher, get moved by forklift, and sometimes sit for weeks before going out to farmers. A sack whose seam blows out on the fifth layer or stretches when the forklift lifts it isn't just lost feed, it's a dirty warehouse and rework. We've handled custom sack printing for feed producers, and this page is about the feed mill.
Gramage and Construction for Stacking
Stacking load is the main consideration for a feed sack. A 50 kg sack stacked eight layers deep carries hundreds of kilos on the bottom layer. Thin PP woven stretches, and a loose seam blows out right there.
For 25-50 kg feed, we recommend 90-110 gsm PP woven with a tight weave. That weight keeps the sack shape stable in the stack and holds the pull when a forklift lifts the pallet. For 5-10 kg retail feed that isn't stacked high, 70-80 gsm is enough and cheaper.
Seam type matters too. A tight hot-cut seam at the base holds the granular load without threads snapping, and we add a glued fold at the mouth for feed that gets stitched on your automatic filling line. Tell us whether filling is manual or done with an automatic stitching machine, because that changes the dimensional tolerance we work to.
Leak-Proof by Feed Texture
Feed comes in different textures and each needs different protection. Coarse pellets are held by ordinary PP woven. Fine mash, crumble, or powder feed can escape through the weave pores and absorb warehouse moisture.
For fine feed we add an LDPE inner liner or inner lamination inside the sack. That layer keeps the particles from leaking through the weave while holding back the humidity that cakes feed. For fish feed and hygroscopic feed, this moisture protection matters so the nutritional quality stays stable until it reaches the farmer.
Mandatory Information and Mill Standards
Feed sacks are tightly regulated on labeling. Nutritional composition, net weight, registration number, producer name and address, and production code are all required. We fit all of it alongside your brand logo and the target livestock type, such as poultry, fish, or ruminant.
The batch code that changes each run gets a dedicated area that can be printed separately or stamped on your line, so the main sack runs in mass production while the production code stays flexible. Our design team helps lay it out to match your plant's internal standard if you already have a fixed template.
Pricing Logic and Scheduling
Feed mills run regular production, so sacks make the most sense ordered in large volume. Wholesale pricing for PP woven with 1-2 color printing is most economical from 1,000 pieces and keeps dropping at tens of thousands. Production runs 7-14 business days for manual-printed PP woven. For regular needs we arrange staggered delivery aligned with your feed production cycle, so the warehouse isn't packed with empty bags at once and cash flow stays easier. We send final pricing within a day of receiving complete specs.
Feed producers who also run a rice line often order rice sacks at the same time, and for the most common base material see the PP woven spec we use for nearly every feed sack. We can run it as a single coordinated order.
