Frequently Asked Questions

WHAT ARE BULK BAGS?

Flexible Intermediate Bulk Container (or FIBC), also called Bulk Bag, Jumbo Bag, or simply Big Bag, is a container manufactured from flexible materials (usually polypropylene) and can carry up to 2000 kg capacity. They are designed to carry dry, homogenous, free-flowing products and offers maximum utilization of cargo space.

Overall, bulk bags offer a cost-effective and environmentally friendly packaging solution for bulk materials, combining strength, flexibility, and efficiency to meet the diverse needs of modern industries.

WHAT ARE BULK BAGS MADE FROM?

100% virgin polypropylene, which is a petroleum-based product. Our bags are made from high-quality, virgin polypropylene, which gives you the ultimate in quality and value for your product. You can be sure your goods are safe and protected, from storage to transport to discharge at their final location.

WHAT SIZES DO BULK BAGS COME IN?

Bulk bags can come in a variety of sizes depending on customer requests. They can be designed and manufactured to accommodate the type of product and machinery customers are using to fill their products into the bulk bag. At SPI, our experts will help you determine the best design and size to fit your needs.

WHAT ARE BULK BAG LINERS?

Bulk bag liners are often used for food grade products and very fine powders. They provide additional protection such as oxygen barrier, moisture barrier, chemical resistance and/or anti-static properties.

At SPI, liners can be inserted loosely or attached to the bag as well. There are different types of liners for different applications, but the main two are tube liners and form fit liners.

Reach out to us to find out if your bulk bag should incorporate liners, and which type of liner to use.

WHAT ARE FOOD GRADE BULK BAGS?

Food grade bulk bags are bulk bags designed with the intention of coming into contact with and storing food products. To fulfill this criteria, stringent hygiene practices are put in place and rigorous adherence to high quality standards are expected in our factories at all time. SPI is certified by FSSC22000, an international certifying body that provides companies in the food industry with an ISO-based food safety management system certification that is recognized by the Global Food Safety Initiative (GFSI).

WHAT IS SAFE WORKING LOAD (SWL) AND SAFETY FACTOR (SF)?

Safe Working Load is the amount of load, which a bag is designed to carry.

Safety Factor is the industry standard requiring the FIBC to handle five or six times its Safe Working Load, (SWL), normally written as a ratio, “5:1 or 6:1 SF”.

Remarks: Single-Trip Bag (Bag designed for one trip only) must meet a SF of 5:1 whereas a Multi-Trip Bag must meet a SF of 6:1.

CAN I REUSE A BULK BAG?

A Single-Trip Bulk Bag is designed to be used for one filling and one discharge, while a Multi-Trip Bulk Bag is designed to be used for more than one filling and discharge. A bulk bag must have a Safety Factor of at least 6:1 to be considered as a Multi-Trip Bulk Bag. Multi-Trip Bulk Bags must also be reconditioned and thoroughly inspected for safety before they are reused.

HOW SHOULD BULK BAGS BE STORED?

All bulk bags made by SPI come with UV resistance, but you should store them in a safe, clean environment out of any direct sunlight exposure or moisture. Cover them well to protect bulk bags from dirt and dust.

ARE BULK BAGS ENVIRONMENTALLY FRIENDLY?

Bulk Bag are well renowned for being 100 percent green. It is recyclable and reusable. Consequently, you can still use these bags for another purpose after disposing of them permanently. Additionally, the production method used makes sure that very little carbon footprint is produced.

WHAT ARE PP CARGO SLINGS?

PP Cargo Sling are made from woven PP (Polypropylene), which is a specialized product for containing, loading and unloading by cranes or forklifts, many small 25kg – 50kg bags at a time, with normal load from 1 – 2 tons.

Belt lifting: this is the main bearing part for loads from 1 ton to 2 tons of cargo. The belt is usually 7cm wide, the position of the belt is sewn on the bottom fabric and the length of the belt depends on the number and size of the small bags inside. Position of the belt should be secured when lifting and hoisting so that the small bags inside do not fall out. The top of the belt is attached with auxiliary belts and straps to secure the belts that cover the product inside.

PP CARGO SLINGS APPLICATION?

  • For lifting 20 – 50 small bags at once, corresponding to the load of 1-2 tons.
  • Often used to transport goods by ship.
  • Used to arrange stored goods for more space and clean.
  • The packaging solution makes loading and unloading goods safe and fast.
  • Saves a lot of labour cost.
