Manufacturer of big bags for grain, sand, and rubble
Today, big bags have become one of the most popular types of bulk packaging on the market. Their highly flexible design allows virtually any type of bag to be created for use across all sectors of industry. Thanks to their excellent transport properties, big bags are widely used in numerous industries.
In agriculture, they are used to transport grain, fertilisers and animal feed. In construction, they are used for carrying sand, gravel and cement. The chemical industry values them for their resistance to hazardous substances, while the food industry uses them to transport dry bulk products such as flour and sugar. Their versatility also makes them suitable for the timber and metallurgical industries, establishing them as an essential part of modern logistics.
Big bags are manufactured from woven polypropylene (PP). The fabric can be either uncoated or laminated, meaning coated and non-breathable. It can also be divided into flat-woven and circular-woven fabrics. PP fabrics are UV-stabilised and fully recyclable, directly contributing to environmental protection and cost savings.
Big bags and woven polypropylene bags are gaining popularity across various industries due to their versatility and durability. They offer a practical and cost-effective packaging solution for businesses. The polypropylene fabrics used to manufacture big bags provide excellent tensile strength and resistance to mechanical damage. As a result, these products can withstand heavy loads, making them ideal for transport and storage. They are also resistant to chemicals, allowing hazardous substances to be stored safely. Their low weight helps reduce transport costs. These fabrics may also have antistatic properties and are easy to clean, making them indispensable across many industrial sectors.
The most common big bag designs include one-loop, two-loop and four-loop bags. Big bags can also be fitted with LDPE film liners. They can be equipped with an internal structure known as a form stabiliser, which helps the bags retain their shape after filling.
Big bags are also classified according to their electrical conductivity. These include Type B and Type C bags, which are used for transporting materials that may generate electrostatic charges.

One-loop Big Bags, single-loop Big Bags, single-handle Big Bags
One-loop and two-loop Big Bags have a simpler design and are more cost-effective than four-loop Big Bags. They are manufactured from tubular, circular-woven fabric to provide greater resistance to tearing along the sides. The lifting-loop sleeves can be made in different colours, allowing the contents of each bag to be identified quickly and easily.
The most common design is made from uncoated fabric, with an open top and an internal PE liner. Base designs vary depending on the intended application. The bottom can be closed with a square, star-shaped or single seam. Discharge spouts can also be incorporated, in which case the bottom is sewn using a square seam. For manual filling systems, the bags are supplied on pallets in quantities of 500. They can also be supplied on rolls for use in automated filling stations.
This type of packaging—one-loop, single-handle Big Bags—is most commonly used in the fertiliser and chemical industries.
Typical filling capacities for these bags are 500 kg, 600 kg and 1,000 kg.
Two-loop Big Bags, twin-loop Big Bags, two-handle Big Bags
One-loop and two-loop Big Bags have a simpler design and are more cost-effective than four-loop Big Bags. They are manufactured from tubular, circular-woven fabric to provide greater resistance to tearing along the sides. The lifting-loop sleeves can be made in different colours, allowing the contents of each bag to be identified quickly and easily.
The most common design is made from uncoated fabric, with an open top and an internal PE liner. Base designs vary considerably depending on the intended application. The bottom can be closed with a square, star-shaped or single seam. Discharge spouts can also be incorporated, in which case the bottom is sewn using a square seam.

Four-loop Big Bag, four-handle Big Bag
Big Bags are one of the most cost-effective and practical packaging solutions for transporting and storing dry bulk products. They are manufactured from either tubular or flat-woven polypropylene (PP) fabric.
The fabric can be coated or uncoated and is available in various weights, depending on the required Safe Working Load (SWL) and Safety Factor (SF).A Big Bag can be as simple as an open-top bag with a flat bottom, commonly used in the construction industry, or as advanced as a high-tech packaging solution manufactured in a clean-room environment for the food and pharmaceutical industries.
Most importantly, every Big Bag is manufactured to meet the specific requirements of each customer.
Q-bag (big bag)
The Q Big Bag is constructed with internal baffles that help the bag maintain its cubic shape after filling. The baffles are specially designed to allow the material to flow freely into the corners of the bag. Thanks to its unique design and cubic shape, the Q Big Bag requires less space and can reduce transport costs by up to 30% compared with a standard Big Bag.
Ventilated four-loop, four-handle Big Bags.
Bags for potatoes and vegetables are manufactured from ventilated polypropylene (PP) fabric.These fabrics are specially designed to allow air to circulate freely through the material and inside the bag. The most common closure is a Raschel mesh filling skirt, which enables potatoes and vegetables to breathe freely—an essential requirement for proper storage and transport.
Big Bags with PE liners
We offer Big Bags with film liners, an excellent choice for companies seeking efficient solutions for packaging and transporting bulk and granular materials. The liner, typically made from low-density polyethylene (LDPE), provides an additional protective barrier that safeguards the contents against moisture, contamination and other external factors. This ensures better protection during transport and storage, which is essential in industries such as chemicals, agriculture and construction. These bags are also exceptionally durable and can be reused multiple times, helping to reduce costs and minimise waste.
The moisture protection provided by Big Bags with internal film liners is particularly important. Thanks to this feature, materials sensitive to external factors can be stored and transported without compromising their quality. Maintaining an appropriate moisture level is crucial for hygroscopic products such as fertilisers and food ingredients. These bags are also ideal for storing construction materials that require protection from moisture. The film liner helps extend the shelf life of products and minimises the risk of material losses.
Big Bags with internal film liners are used across a wide range of industries, demonstrating their exceptional versatility. In the food industry, including flour and sugar production, they protect products against moisture and contamination, helping to preserve their quality. In the chemical industry, these bags are used to transport bulk substances such as powders and granules, improving workplace safety. In construction, they are suitable for storing cement and sand while protecting the contents from moisture. Their ease of handling and transport makes them a popular and efficient solution on construction sites.
