Types of Top Attachments
Open Top –
The bag does not come with an inlet closure, best suitable for products like sand, stones, and building materials as these materials do not require protection from weather conditions. Open-top bags are ideal for both manual and automation filling.
The spout top comes with PP strings to close and seal the opening. Spouts are ideal for automated plants where hoppers are used for filling, and the product loss is controlled by attaching the spouts to hoppers. The most common size is 14″ x18″/35cm x 50cms.
Skirt / Duffle Top-
The extra piece of fabric is attached and sewed to the Top of the bag, which comes with PP tie strings to close the bag’s opening. It protects the product from weather conditions and external contaminations, making it an ideal choice for non-automated packaging operations.
The flap top is a lid (a piece of PP fabric) sewn on one side of the bag and can be closed with binding tie strings on the other end of the bag, it provides mild protection to the material filled inside the bag.
Spout top with Flap-
This option is a combination of Flap Top and Spout Top, which adds extra protection to the bag.
Conical Spout Top
This option comes with a spout for filling, the Cone-Shaped Top allows maximum utilization of the space in the bag.
Types of Bottom Attachments:-
Flat bottom closure does not have any additional closure attached to the bottom of the bag, the product is emptied by cutting the bottom with a sharp object. This option is used mainly in the Construction and Mining industries.
A spout is attached at the center of the bottom, and the diameter of the spout controls product outflow. The diameter could be anywhere between 25cms to 50cms, depending upon the length and the width of the bag’s bottom. The spout’s length is usually double of the spout’s diameter and can be customized to the user’s requirements
Full Open Dump
The skirt is made of heavy fabric that replaces the bag’s bottom. A good practice is to use skirts with a protective flap to provide extra protection to the bag, the bags are used to extract the product all at once or for the products that are hard to discharge through spouts.
Spout With Iris Closure
It acts as a discharge valve suitable to control the product outflow by chocking the neck of the spout
Spout With Petal Closure
The added feature to the spout is to hold and protect the spout closure, helps to minimize the bulging and prevents contamination.
Conical Spout Bottom
The conical Bottom is used to extract the extra accumulated product in the corners of FIBC bags. The tapered conical bottom ensures an easy outflow of the material.gh spouts.
Other Important Discharge Features
Folding- Goose Neck or Swan Neck

Types of Lifting Option:-
The loops can be made with Polypropylene and Multifilament (seat belt material).
Corner loops are sewn on all four corners of the bag, the forks use the loops to transport/ lift the load. The most standard size is 10 Inches or 25cms.
Cross Corner Loops-
Cross corner loops are sewn on eight reinforced patches of the bag, the loops provide a larger opening to lift the bulk bags. The loops are sewn on Circular, Baffle, and U Panel bags on reinforced strips on the bags’ panels.

Bag Topple loops for easy roll over-
These are optional loops sewn at the bottom of the bag to enable easier emptying of the bag.
Single/Double/Loop-On-Loop Stevedore Straps –
These supporting loops are specially designed to handle the bags in many ways, such as- Single Stevedore Pulling through the loops at the corners to connect them for lifting, wherein Double Stevedores connect the loops on each side parallelly and the third type is, four supporting loops connected on each loop of the bag separately.
1 and 2 loops-
These loops are entirely made of the body fabric of the bag itself, which is extended to form a loop-like shape, these loops are reinforced with an added piece of fabric.
