Fertiliser and Garden Bags

Fertiliser, growing media, soil additives and agricultural inputs are heavy, sometimes abrasive, often hygroscopic, and rarely handled gently. A heavy duty sack in this range is specified for drop strength and puncture resistance first, and for shelf appeal second — which is the correct order for a product that spends its life in a garden centre yard.

Three Failure Modes We Specify Against

1. Drop. A 5 kg or 25 kg sack dropped onto a concrete floor bursts at the bottom seal. Wider seal lands and a heavier sealant layer are the fix, not thicker film alone.
2. Puncture. Granules and mineral additives abrade the inside; pallet corners and forklift tines attack the outside. Film thickness and laminate choice are decided from the product’s particle shape.
3. Moisture. Most fertiliser cakes solid if it takes on water. A foil or high-barrier laminate and a properly closed top are what keep a sack saleable after a wet month outdoors.

Handling and UV

Carry handles, hang holes and reinforced top seals are all available. Where a sack is stored outdoors for long periods, UV-stable inks and a laminate that does not chalk are worth specifying — a bleached bag reads as old stock whatever the date code says.

What Is in This Range

Printed heavy duty sacks from 250 g through 1 kg, 2 kg and 5 kg retail sizes to 25 kg trade weights, in plain, foil and recycled-content laminates, with zippers on smaller resealable packs and EN 13432 compostable structures where the growing medium market asks for them. Larger and non-standard weights are quoted individually — send the fill weight, the particle description and the storage conditions and we will specify against them.
