Our industrial paper bags
Industrial experience you can trust
At Innovaciones Subbética, we have more than thirty years of experience manufacturing paper bags for professional, retail, and food sectors. This accumulated expertise allows us to confidently address a key challenge in today’s market: the development of industrial paper bags such as double-layer bags and SOS bags for packaging.
Double-layer
industrial paper bags
Designed for maximum strength and reliability
At Innovaciones Subbética, we have been manufacturing paper bags for professional, retail and food sectors for more than thirty years.This accumulated experience enables us to confidently address a key market challenge: offering double-layer industrial paper bags with handles that combine strength, safety and ease of handling in environments where packaging plays a critical role in product operation and presentation.
Designed to meet demanding industrial requirements
Our double-layer bag is not a standard solution. It is designed to withstand stress, weight, environmental conditions and continuous handling. For this reason, it is manufactured using long-fibre Kraft paper, white papers, smooth or calendered finishes, always selected according to the product and its expected performance.
Key advantages of double-layer construction
- Greater resistance to tearing and rupture.
- Structural stability for heavier loads.
- Improved protection of the content.
- Optimal behaviour during transport and storage.
- Professional presentation that reinforces the customer’s brand.
Our work always begins by analysing the nature of the product, its filling method, density, logistics and environmental conditions. Only in this way can we offer a truly suitable and efficient solution.
Total adaptation
Each product requires its own bag
In industrial markets, there are no standard solutions. That is why we develop each bagon a customised basis:
- Dimensions and volumes.
- Paper types and grammages.
- Structural reinforcements according to product density.
- Handle design based on intended use and target weight.
- Flexographic printing options, from simple to complex designs.

Industrial SOS bags
Designed for maximum product presentation and stability
At Innovaciones Subbética, we have more than thirty years of experience manufacturing paper bags for professional, retail, and food sectors.
This background allows us to now incorporate an essential format in food packaging: the industrial SOS bag (Self-Opening Sack), a final package designed to be filled at the factory and displayed directly at the point of sale.
It is a reliable, stable, and technically proven solution, widely used across Europe for dry food products.
Designed for precise filling and high-quality presentation
The industrial SOS bag is characterized by its square bottom, which ensures stability during filling and display, and by its side gusset structure, which allows for a regular volume and easy handling.
Manufactured with papers selected according to the product’s density, it ensures optimal performance on automatic machines and high mechanical strength.
The industrial SOS bag offers key advantages:
- Automatic opening (Self-Opening Sack) for fast filling.
- Structural stability across all formats.
- Resistance to weight, tearing, and handling.
- Excellent shelf presence.
- Optimized for palletizing and storage.
- 100% paper packaging, recyclable and made from renewable sources.
A safe, sustainable industrial package perfectly adapted to the operational needs of food manufacturers
A final package for food products
Reliability, consistency, and presentation at the point of sale
The industrial SOS bag is the traditional reference packaging for dry food products such as flour, sugar, rice, salt, semolina, and other granulated products, as well as breadcrumbs and dry mixes.
It is manufactured in the standard 1 kg, 2 kg, and 5 kg formats, adapting to each manufacturer’s needs and filling systems.
Customization and adaptation to each project
Each food product behaves differently during filling, transport, and shelf display. For this reason, we develop each bag according to:
- Required format and volume.
