Transporting and storing hazardous materials is challenging and you must follow strict safety rules. Because these materials can be dangerous, a special type of bulk bag is needed: a UN Certified Bulk Bag.

Whether you're dealing with chemicals, flammable substances, or materials that pose a risk of contamination, UN Certified Bulk Bags offer the durability and reliability needed to keep your operations safe and compliant.

When selecting a FIBC big bag supplier there are many factors that go into the decision-making process including price. Many factors contribute to the cost of the bag you’re buying, but how do these factors affect the price of each bag? Pricing can change monthly and here are 4 of the biggest contributing factors why.

If you’re already using FIBCs (Flexible Intermediate Bulk Containers) to move or store hazardous materials, you’re probably using UN bulk bags. If not, this guide will help you figure out if they’re right for your needs 

In certain situations involving the storage and transport of hazardous materials, a standard FIBC won’t suffice. Standard bags are chemically resistant from manufacture because of the woven polypropylene in which they are constructed; certain materials are too corrosive and/or dangerous to use a standard bag.

Bulk bags with baffles are standard bags with extra fabric panels or pieces of string sewn into each of the bag’s four corners. This special reinforcement allows the bag to better hold its square shape when filled making bags with baffles easier to store side by side and/or stack.

Bulk bags are an extremely versatile bulk packaging option. If the material/product is dry and flowable, you can store or transport in these amazing bulk packaging bags.

GFSI, or Global Food Safety Initiative, is an initiative that brings together key actors of the food industry to collaboratively drive continuous improvement in food management safety systems around the world. Together, these actors work on a multitude of projects to drive global change in food safety.

Flexible Intermediate Bulk Containers (FIBC), also known as bulk bags, are a cost effective bulk packaging solution. Although bulk bags are very affordable, a market for inexpensive “used bulk bags” has begun to develop. FIBC “recyclers” and “refurbishers” such as Bulk Bag Reclamation have been popping up to capitalize on this new developing market.

Depending on your product and/or application, your bulk bag needs change. FIBCs have a multitude of uses across a wide variety of industries. Because of this, a very large number of specialty bags have been created to fit unique products applications in order to better serve the users.

Before deciding to purchase FIBC bulk bags, it’s important to educate yourself. Part of that process is catching up on all of the different terms. We made this guide to help you make the most informed purchase.

Polyethylene liners, commonly referred to as poly liners, are flexible plastic liners specifically designed to line the inside of a flexible intermediate bulk container (FIBC or bulk bag).

There’s quite a bit of confusion encompassing food grade bulk bags. There are so many regulatory bodies and entities that offer guidelines on food packaging that it’s hard to keep track of! There’s AIB (American Institute of Baking), FDA (Food and Drug Administration), HACCP (Hazard Analysis Critical Control Point), ISO 22000 (International Organization for Standardization) BRC (British Retail Consortium) and, the latest and greatest, GFSI (Global Food Safety Initiative).

FIBC bags are a revolutionary bulk packaging option that are both environmentally friendly and cost-effective. Flexible Intermediate Bulk Containers can store and transport all different types of materials including both hazardous and non-hazardous dry flow-able materials.

Food safety in the packaging industry is ever evolving and stricter industry standards and government regulations are becoming the norm. On top of tougher standards, there are more third party accreditations that are recognized and sometimes required by large food manufacturers and retailers to keep track of.

Advances in synthetic polymers over the years have given rise to new innovative materials with a wide variety of applications. One such polymer, called polypropylene, has been particularly useful in the packaging industry.

Flexible Intermediate Bulk Containers (FIBCs) are a fantastic option for transporting and storing dry flow-able products. If you are currently exploring new methods for transporting and storing your dry flow-able product, here are five reasons why you should consider using FIBC bags.

Flexible Intermediate Bulk Containers, also known as FIBCs, are used in a variety of facilities including food manufacturing and food processing plants. Food grade bulk bags are a great option for transporting and storing food and food related products. Lets examine the five biggest reasons why successful commercial food companies use food grade bags over alternative handling methods.

When it comes to sourcing FIBCs you have two options – buying from a domestic manufacturer in the US, or a distributor that partners with overseas manufacturers. The vast majority of bulk bags distributed in the US are made overseas.

Adhering to strict procedures and quality standards to protect against contamination is a never-ending job in the pharmaceutical industry. It requires discipline and attention to detail during every step of the process from manufacturing to packing, handling and transportation.
