Industrial bags and sacks

Bags and sacks for your product: how to choose and how to close them

Multiwall paper, woven or laminated polypropylene, valve, jute or with liner. The right bag depends on your product and how you will fill and close it. We help you with all three.

Bag types

Six bag types and how each one is closed

Each card tells you which equipment you need to close it.

Woven polypropylene

Strong and economical. The most widely used for feed, sugar, salt, fertilizer and grains.

Closed with: Single stitch or fold-over
See the equipment →

Multiwall paper

Single or multiwall, with or without a plastic liner. Ideal for flour, cement and powdered products.

Closed with: Sewing with crepe tape, pinch or hot melt
See the equipment →

Valve bag

Filled through a valve in the corner and closes by itself. For fine powders and high-speed filling.

Closed with: Valve filling, no sewing
See the equipment →

Gusseted

Side gussets that give the filled bag a box shape: more stable stacking and better presentation.

Closed with: Band sealing or sewing
See the equipment →

With inner liner

A plastic bag inside the sack protects hygroscopic products from moisture.

Closed with: Sealed liner + sewn or pinch bag
See the equipment →

Jute and cotton

Natural, breathable fiber, traditional for coffee, cocoa and some grains.

Closed with: Sewing with a portable or a pedestal unit

Still filling and closing your bags by hand?

A filling scale and a bag closer can multiply bags per hour, eliminate product given away through overweight and give every bag an even closure.

Frequently asked questions

Which bag is best for animal feed?+

Woven polypropylene is the most widely used for its strength and cost. If the feed is fine or hygroscopic, add a liner or use a laminated bag.

Which bag is best for salt?+

Woven or laminated polypropylene, preferably with a liner. And the equipment that fills and closes it must be corrosion-resistant.

Do you sell bags in small quantities?+

No. Bags are imported on special order with a minimum of 150,000 units (20,000 for paper bags). If you need only a few units, we recommend a retail packaging distributor.

Do you sell small paper bags?+

We do not sell paper bags under 10 kg. We work with industrial multiwall paper and polypropylene bags for heavier fill weights.
