1. Loop Design Options
The loop design is an essential feature that determines how the bag can be lifted, handled, and transported. Waterproof Laminated Bulk PP Jumbo Bags offer several loop design options, each suited for different handling and lifting methods.
Cross Corner Loops
Cross-corner loops provide ideal lifting support by attaching the loops to the four corners of the bag, making it easy to lift the bag from all sides.
Side Seam Loops
Side seam loops are attached to the sides of the bag, offering a more streamlined design.
One/Two Loops
For lighter applications, a design with one or two loops may be preferred.
Ancillary Loop / Loop Extender
An ancillary loop or loop extender can be added to enhance lifting options, especially when dealing with taller or heavier bags.
Four Corner Belt Around Loops
For even distribution of weight, the four corner belts around loops ensure that each corner of the bag is properly supported.
Stevedore Loop
The Stevedore loop is a specialized design that is often used in marine and port handling. It offers additional durability and support, making it ideal for transporting bulk materials in and out of shipping containers.
2. Top Design Options
The top design of the bag is crucial in ensuring how the material is loaded into the bag, how it is sealed, and how it is accessed during unloading. The following are the different top design options available for Waterproof Laminated Bulk PP Jumbo Bags:
Open Top
The open-top design allows for easy and quick filling of the bag. This option is suited for dry, bulk materials that do not require a sealed top, providing a fast and efficient loading process.
Skirt Top
The skirt top features an extended flap around the bag’s opening, offering additional protection from contaminants and preventing spillage during loading.
Filling Spout Top
The filling spout top offers a controlled and precise method of filling the bag. The spout can be fitted with a valve or other sealing mechanism, reducing the risk of spillage and contamination during the filling process.
Flap Top
A flap top provides a secure closure for the bag after it is filled. The flap can be folded over and sealed to keep the contents protected from environmental factors, dust, or moisture.
3. Bottom Design Options
The bottom design of a Waterproof Laminated Bulk PP Jumbo Bag plays a crucial role in ensuring the safe and efficient discharge of the contents.
Closed Bottom
A closed-bottom design ensures that the contents remain securely contained within the bag. It is often used for static storage and transport, ensuring that the material stays inside the bag until it is ready for unloading.
Cross Bottom
The cross-bottom design offers additional stability and balance. This design is ideal for heavy loads as it evenly distributes weight, reducing the risk of bag breakage or failure during transport.
Tic-Tic Toe Cross
The tic-tic toe cross bottom offers a specialized pattern for improved load distribution and increased strength.
Parallel Sling Support
This bottom design features parallel slings that provide additional support, particularly for large and heavy bags.
Spouted Bottom
A spouted bottom allows for controlled discharge of the bag’s contents. The spout can be fitted with a valve or opening for easy emptying of the bag. This is commonly used for granular or powdered materials.
Fully Belted Spotted Bottom
The fully belted spotted bottom offers enhanced stability and strength by adding additional belting around the bag’s bottom.
Full Bottom Discharge
Full-bottom discharge bags are designed for quick and efficient emptying of contents. This design is particularly beneficial when materials need to be discharged quickly and in large volumes, reducing handling time.
