Paper sacks from
Feldmann Verpackungen

Robust industrial packaging for smooth production processes.

“Anyone looking for a paper sack for industrial use needs more than just printed paper. They need packaging that can withstand the pressure of the filling system, secures the product, and arrives on time. Whether it’s fine powder, sharp-edged granules, or free-flowing bulk materials: we design the sack that perfectly matches your product and your machinery.”

Why companies choose Feldmann

In day-to-day B2B operations, empty promises don’t count; process reliability and cost-effectiveness do.

What speaks for Feldmann paper sacks:

The product remains as it is

Moisture, oxygen, and pests stay out. Through clever material combinations (PE interlayers, inliners), we guarantee the durability and free-flowing properties of your filling material.

Your systems run continuously

We precisely match the format, valve, and air permeability to your filling technology. The result: maximum cycle rates, clean valve sealing, and no downtime due to faulty sacks.

Secure logistics

Our kraft paper sacks are extremely tear-resistant. The precise box shape of the filled sacks ensures stable pallets that can withstand even rough transport routes.

Genuine sustainability

Paper thickness is reduced (Down-Gauging) without loss of stability, which saves material costs and improves the CO2 balance – with full recyclability.

Industry solutions:
The right material for every filling product

We know the strict standards and harsh conditions of your industry. Feldmann provides the appropriate specification.

Food Industry

Hygiene is paramount. Our paper sacks for food are made from food-safe materials with low-migration inks. We also have suitable, tight sealing solutions for dusty products like flour or paper sacks for grain.

Typical filling materials

Flour, baby food, sugar, starch, baking ingredients, grain

Chemical Industry

Aggressive or hygroscopic substances do not tolerate packaging errors. Our barrier sacks are leak-proof and protect people, the environment, and the product.

Typical filling materials

Plastic granules, color pigments, specialty chemicals, fertilizers

Building Materials Industry

On construction sites, materials are not handled delicately. Our Paper sacks for cement, mortar, and gypsum are extremely robust and, thanks to micro-perforation, de-aerate quickly and without tearing during rapid filling.

Typical filling materials

Cement, gypsum, tile adhesive, construction chemicals

Feed industry

Pet food must remain storable and protected from pests. Our feed sacks are resistant to moisture and easily withstand the often rough handling in agriculture.

Typical filling materials

Pet food, compound feed, mineral feed, seeds

Plain talk: Frequently asked questions
from our customers

Will your sacks run smoothly on our existing filling systems?

Yes. Before we produce, we clarify your technical parameters: What is the filling process? How must the valve be constructed? Then we design the sack construction, valve size, and paper porosity precisely so that you can run your machines at maximum speed.

Are the sacks approved for direct contact with food?

We use papers, adhesives, and printing inks that are strictly approved according to current EU regulations for food contact. You will receive the corresponding declarations of conformity for your audits (e.g., IFS, BRC) proactively from us.

Do your sacks protect hygroscopic powders from clumping?

Yes. To achieve this, we use moisture barriers. Depending on requirements, we integrate PE-coated papers or a free-standing PE film (Free-Film) between the paper layers. Your product remains dry and free-flowing.

How does Feldmann secure our supply during fluctuating demand?

Nothing is more expensive than a production line that stands still because packaging is missing. We work extensively with framework agreements and call-off orders. This means: We produce based on your annual planning, store inventory for you, and deliver exactly when you need the sacks – reliably and on time.

Can I reduce plastic usage by using your sacks?

Yes, in many cases. By using modern, high-strength papers, we can eliminate the need for additional plastic layers for many products or reduce the grammage of the paper without the sack tearing. We would be pleased to review your current packaging concept for potential savings.
