What Are the Standard Sizes of Ton Packs (FIBC Bags)?
A Clear Guide from the Smallest to the Largest Sizes

Ton packs (FIBC / Flexible Intermediate Bulk Containers) are widely used across various industries, including industrial waste transportation and material storage and handling at construction sites.
Although they may appear similar at first glance, ton packs actually come in a wide range of sizes and specifications depending on their intended use.

This article provides a clear overview of the most common ton pack sizes, from small to extra-large.

1. Standard Size | 1,000 L Capacity

The most commonly used ton pack is the standard 1,000-liter type.
When people refer to a “ton pack” or “bulk bag,” this is typically the size they have in mind. It is widely used at construction sites and across many industries.

Beige-colored ton packs (e.g., 1100KR-B, RM-001) are especially popular and are considered industry-standard products.

The standard size also includes several variations:

Breathable black ton packs (e.g., 1100KR-BW)
Designed to quickly release moisture from the contents, making them suitable for damp materials.

Weather-resistant ton packs (e.g., 1100KR-UV3)
UV-resistant fabric helps prevent material degradation and allows for long-term outdoor storage.

2. Small Sizes | Easy Handling in Confined Spaces

At sites where forklifts cannot easily access or where working space is limited, smaller ton packs are often required.

Fukuroya Fukunaga has expanded its lineup of small-size FIBC bags to meet these on-site needs.

Representative model: 650KHR-C

Easy to handle even with manual operation

Safe working load: 1,000 kg

Equipped with a body belt to prevent excessive bulging

This size is commonly used for storing metal parts, raw materials, and powders.

Even for small-size FIBC bags, all products undergo testing in compliance with JIS standards, confirming fabric strength, load capacity, and safety factors to ensure reliable quality.

Drum-Compatible Type

For applications requiring the bag to be placed inside a drum, the DRUM900KHR-C is the ideal solution.

Inner coating applied

Suitable for transporting dust and fine powders in the chemical and metal manufacturing industries

Ultra-Compact FIBC Bags

The 500KR(B) is an ultra-compact FIBC bag with a capacity of 100 L and a safe working load of 100 kg.

Blue color for high visibility

Useful for color-coded material management

3. Extra-Large Sizes | Ideal for Lightweight, Bulky Materials

For lightweight but bulky materials such as rice husks, paper waste, and expanded plastics, large-capacity FIBC bags are most suitable.

The 1740FS is an extra-large model with a capacity of 2,100 L, exceeding average human height.

Stable handling with four-point lifting loops

Equipped with a top cover for safe storage and transport

This type is widely used in agricultural applications and recycling facilities.
