吨包袋的结构主要包括袋身、顶部填充口、底部卸料口和吊带。袋身通常由聚丙烯等高强度塑料材料制成，具有足够的耐用性和抗拉强度，能够承受重物的重压。顶部填充口用于方便将物料倒入袋子内部，通常有拉链、开口拉绳等设计，可以有效防止物料外泄。底部卸料口用于方便将物料从袋子内部倒出，通常采用阀门或开口的形式，方便卸料操作。吊带通常由高强度的尼龙材料制成，用于提升和搬运袋子。

吨包袋的特点有以下几点：

1. 结实耐用：吨包袋采用高强度塑料材料制成，具有较高的抗拉强度和抗压性能，能够承受大量物料的重压和摩擦，不易破损。

2. 防水防潮：吨包袋具有优良的防水和防潮性能，能够有效保护袋内物料不受潮湿和水分影响，保持物料的质量和原有性能。

3. 防尘防静电：吨包袋表面光滑，具有一定的防尘功能，能够防止灰尘和杂质对物料的污染。同时，吨包袋还具有一定的防静电功能，能够有效防止静电对物料的影响。

4. 方便搬运：吨包袋设计有吊带，方便搬运和提升袋子。吊带采用高强度材料制成，能够承受大重量的物料，提高搬运效率，减少人力成本。

5. 环保可循环利用：吨包袋采用塑料材料制成，具有良好的回收性能，可进行循环利用，减少对环境的污染。FIBC bags (Flexible Intermediate Bulk Container) are known by several names in the bulk bag industry, such as FIBC bulk bags, super sacks, bulk bags, totes, one-ton bags, and jumbo bags. Whatever name you know them by, they are used for moving dry products from one location to another.   

There are many different types of FIBC bags to enable numerous dry products to be loaded safely.  From simple to super complex specifications, these bags are sturdy enough to hold 5,000 pounds of dry material and transport it safely to a destination. Many industries use FIBC bags regularly, including the food, chemical, pharmaceutical, and mining industries, and many more.

Types of FIBC Bulk Bags

Type A

Used to transport non-flammable dry products.  This type of Flexible Intermediate Bulk Container or  bulk bag is not manufactured with any anti-static properties, so this type will not eliminate static electricity.  This type of material is not safe to transport any dry product which could be explosive or flammable.

Type B

Type B Flexible Intermediate Bulk Containers are manufactured with insulating fabric and can be used with combustible dust with MIE greater than 3mj.  However, this type cannot be used with any product containing flammable vapors or gases MIE <3mj.

Type C

Type C FIBC bags are used for safely shipping both combustible and flammable products.  This bag has conductive threads laced throughout the material and must be electrically grounded with a wire to work properly.  This type will eliminate the risk of static electricity.

Type D

This bag type is comparable to Type C bags, but due to the material construction, you are not required to physically ground the bag.  Chromiq Blue material is the leading manufacturer of this material.

Always check with a certified FIBC bulk bag company to ensure you are using the correct bag type to reduce the chance of any safety issues.  FIBCA also has really good information about the correct type of bag to use for your specific product.

Certified Flexible Intermediate Bulk Container (FIBC)

Food Grade Certified FIBC Bulk Bags

Certified Bags means the bags were made in a manufacturing facility that has been certified by a company licensed to audit the facility to ensure all safety protocols are being followed when manufacturing.  Several companies will audit the plants to certify them as suitable to manufacture food-grade bags.  Some are BRC, IFS, FSSC, and SQF.

Pharmaceutical Grade Certified FIBC Bulk Bags

Pharmaceutical FIBC bulk bags are manufactured with the most stringent processes to ensure there are no foreign materials in the bags when completed.  These must go through an additional process to vacuum out, run through metal detectors, etc.  There are thorough audits that must take place to certify a manufacturing plant to produce pharmaceutical FIBC bulk bags.  We are able to make any custom bag you may need.

How many types of FIBC bags are there?

There are six main types of Flexible Intermediate Bulk Containers.  They are circular, u-panel, four-panel, baffle bags, vented bags and dewatering bags.  These are discussed below.

Circular

Circular bulk bags are the least costly bag to produce, as the body of the bag is made exclusively by machines. Essentially, they start with a tube and then sew on the type of bottom and top.  These are durable bags, as they have fewer seams where issues can arise.

U-Panel

This design is like the four-panel bulk bag allowing it to keep its square shape while having less stitching.  The less stitching you have on a bag, the less chance of a failure while loading and shipping the product.  Therefore, this FIBC bag design will fall in between circular and four-panel bags regarding durability and maintaining more of a square shape.

Four-Panel

This bag is made using four separate panels which are then sewn together.  This type of bag is going to maintain a better square shape vs. a circular bag.  However, it will not support as much weight as a circular bag due to the additional sewn-in seams.

Baffle Bags

This type of FIBC bulk bag has baffles down the corners of the bag to allow material to flow into the baffles while loading.  The bag only works with dry products which are small and flowable, as they must be able to load into the baffles without getting impeded.  Plastic resin pellets, corn, soybeans, and rice are good examples of products that do well in these bags.  The benefit of a baffled bag is that it will remain very square and allows solid stacking ability.

Vented Bags

This bag has special material which allows the bag to breathe and is good for food items such as potatoes, or other vegetables which may be prone to mold while transporting.

Dewatering bags

For special draining circumstances

Industrial Products Shipped with FIBC Bulk Bags

Mining

Mining is a perfect industry to utilize FIBC bulk bags, as mines are usually in a remote setting and tend to ship the product globally.  These bags are ideal for this environment and can easily be transported out into the field, are easy to load, and are waterproof.
