Ready to ShipTwo-loop bulk bags are designed with two lifting loops for easy handling with hook type lifts. These bags are simple in construction, ideal for lightweight and easy-to moderate material loads. The different types of two-loop bulk bags are usually based on the following features: material, construction, and specific uses. Below are some of the common types:
Cotton canvas bulk bags
A cotton canvas bulk bag is a bag made from cotton canvas fabric. The canvas gives it a very strong and durable finish. The main advantage of a cotton canvas bulks sack is that it is breathable, allowing air to circulate through the bag and reducing the risk of mould or mildew formation in the bag’s contents. This makes it ideal for bags with agricultural produce, seeds and such. However, the cotton canvas bulk bag is heavier and more expensive than other options and its colour may fade with time.
Jute 2-loop bulk bags
A jute 2-loop bulk bag is made out of plant-derived Jute material. Jute is strong and very durable and in fact, comparable to sited much synthetic materials. Jute 2-loop bulk bags are environmentally friendly as jute is a natural fibre that can be degraded back into the environment. It provides an affordable option for help because it is cheaper than a cotton canvas bag, albeit less lasting. They are mostly used to package agricultural products like grains, potatoes, onions and other similar produce.
Canvas bulk bags
Canvas bulk bags are made out of the sturdy and durable cotton fabric that is known as canvas. Canvas Bulk Bags are used frequently to carry and store very many things including grains, chemicals, seeds, and construction materials. It also comes in a waterproof variant which expands its usability. The canvas bulk bags are available in various sizes. The smallest can hold up to 50 kilograms while the larger ones can hold up to a tonne and in fact even more.
Coir bulk bags
Coir is basically extracted coconut husk fibres. Coir bulk bags are bags constructed from this very fibre. Coir is strong, biodegradable, and environmental friendly, also very durable when wet, hence suit sown for carrying items that have moisture content. These bags are mostly used for carrying horticultural products like coconut chips and coir dust. However, Coir bulk bags can also be used to carry non-horticultral items like construction aggregates.
Mesh 2-loop bulk bags
Mesh 2-loop bulk bags have mesh features that allow air to pass through the bag. They are made of synthetic materials like polypropylene. This feature prevents moisture build up and make the bag ideal for storage of products susceptible to mould and spoilage. The mesh structure offers visibility of the contained product and allows easy inspection. The mesh 2-loop bulk bags are used commonly in agriculture, construction industries, and fisheries.
Diamond design
The diamond design refers to a diamond cross pattern or diamond design structure. It is a popular choice for 2 loop bulk bags that are meant to carry very heavy items. The diamond design, also known as a diamond pattern design or a diamond weave, comes with extra support on stress points on the bag. This helps reinforce the bottom and sides of the bag thus aiding better load distribution. This design prevents the contents of the bag from causing stress concentration and potential tearing within the bag. The design also has better stacking and handling capabilities of such bags in storage.
Baffles design
The baffle design consists of interior baffles or partitions that help keep the bag's shape and standard consistency during filling and transportation. Baffles enhance stability by preventing the contents from shifting around inside the bag. This makes it suitable for such applications where uniformity and consistency of the contents are such a priority. Baffled bags are popular in the food, chemicals, and agricultural industries. They are preferred because of their enhanced stability and shape retention, especially when carrying granular or powdery substances.
Cube design
The cube design is such a simple design. It involves constructing bags into pure cube shapes. Cube designs are very easy to manufacture and have the advantage of stacking easily. This also makes them ideal for storage and transportation save on space and efficiency. The cube design bulk bags are used mostly in construction materials and bulk powders. In these two scenarios, stability and ease of handling are of utmost importance.
Ventilated design
The ventilated design contains strategic openings or perforations within the bag. These features are meant to allow airflow through the bag. The ventilated design is used commonly for agricultural applications. Some of the items include rice, grains, fruits and vegetables. These items need air circulation to deter moisture build up and spoilage emergence. While the airflow feature is beneficial, it makes the ventilated bags weaker in comparison to the other designs. They are thus suited best for lighter, moisture susceptible products only.
Funnel top design
The funnel top design has a narrow, funnel shaped opening at the top of the bag. This design aids easy and faster filling of the bag during processing. Most funnel top bags are equipped with drawstrings to enable regulation of the bag's content. This feature is useful in preserving the quality of the contents. Funnel top bulk bags are mostly used in industries that deal with powders, seeds, and grains. The design enhances filling efficiency, reduces wastage and allows better handling during transport.
Storage of industrial materials
2 loop bulk bags are used largely in storing industrial materials like sand, gravel, cement, and chemicals. Their durable construction, usually polypropylene, gives them resistance against abrasion and corrosion. This makes them suitable for the tough environment found in factories and construction sites. Because of their ergonomic two-loop design, these bags are lifted and moved easily with hooks in fork lifts and other machinery.
Transportation of agricultural products
In the agricultural sector, agriculture bulk bags are used in transporting grains, seeds and fertiliser. The spacious and strong structure can hold large volumes of agricultural produce. They can be handled very easily because of the two-loop design, which allows use of the machinery in transportation within farms, between regions, and to markets.
Packaging of construction materials
Bulk bags are used commonly to package construction materials such as bricks, tiles and gravel. Because they are made of strong materials, they withstand the rigors of handling and transporting these heavy materials. The two-loop design helps workers manage and move these bags with efficiency on construction sites and in the warehouses.
Waste management
Two-loop bulk bags find applications in waste management. They are used to collect and transport construction debris, recyclable materials, or even municipal solid waste. Their durability ensures that they can contain even the sharped edged wastes without tearing. The loops allow easy handling with grabbers and other waste management equipment.
Packaging of powdered chemicals
Two-loop bulk bags are popular in the chemical industry to package and transport powdered chemicals and raw material. The stature prevents contamination and ensures safety of the chemicals within the bag. The loops design allows easy filling and emptying processes.
Type of material
Bulk bags should be made from strong materials like polypropylene. Polypropylene is hard and works well under pressure. This material also resists chemicals and stays strong in sunlight. The bag's threads should be tight or coarsely woven. Thoroughly woven means the threads are packed closely together. A coarse weave allows air and moisture to escape. Without air or moisture, grains last longer. This is important for food storage. Examine the stitches that hold the bag's seams together. Double or reinforced stitches are much tougher. They make bags bear heavier weights without tearing apart. Bags with flat lock seams are tougher at the edges.
Safe working load (SWL)
Determine how much weight a bulk bag needs to hold in a normal day. The safe working load or SWL should match this requirement fully. Never go for an SWL number that is lesser than the usual load. With time, excess weights will wear the bags out. To challenge the bags, the load should be no more than 25% of their rated capacity. This gives a safely margin. However, do not get an over-sized bag expecting it to hold too much weight. This may cause the bag to become unmanageable and the contents hard to retrieve. Select an ideal SWL that considers both the average and maximum weights that will be carried.
Loop design
Consider the loop design that provides the best benefits. Each type has its own unique benefits depending on the application. The two loop design is simpler and easier to handle, especially where basic stability suffices. Four loops give more stability and better balance. Choose the loop design based on handling requirements and the stability needs during storage and transit.
Refilling system
Consider the bulk bag refilling system that is the most appropriate. Open tops allow easy dumping but may need extra securing. Funnel tops reduce spills during transfer but might slow the filling process. Choosing the right system depends on operational efficiency and cost.
Involvement with the supplier
Work with a reputable supplier that understands industrial needs for bulk bags. Suppliers with experience in giving feedback on material choices, construction reinforcement, and suitable designs for various sectors. Stronger and long-lasting bags will be got from suppliers who use quality materials and manufacture with care.
