When industries, factories, and other production units want to store their products, they opt for bulk storage solutions so that more items can be stored in the least amount of space possible.
If you are looking for the perfect bulk container that will satisfy all of your particular storing specifications, then there are a number of bulk containers that can be used for various storing purposes. Some of these include:
Bulk Bags – Flexible and large storage bags that can be used to store sand, grains and other flowing and dry goods.
Wire Baskets – Easy to stack baskets made of wire mesh that allows for enhanced visibility of the products stored within.
Pallet Containers – Flat platforms on which heavy machinery and merchandise can be placed for easy lifting and transportation with the help of cranes and forklifts.
Stack Racks – Racks with easy to remove metal shelves that allow for installation of small as well as large goods.
Gaylord Boxes – Boxes made out of layers of cardboard that can retain their shape under pressure and are used along with pallets containers for convenient stacking and storage.
Wood Crates – Wooden crates made of firm framework that can transport delicate or uneven shaped objects within them with ease.
IBC Totes – Immediate Bulk Containers, known as IBCs and used for the storage of liquid goods, such as, chemicals, oil, food ingredients, etc.
Bulk containers are not only available new varieties. You can also choose to purchase a used bulk storing solution that is as efficient as a new one. All of the above containers and more are being sold in the market today in new and used versions. So find the one that is suitable for your storage area and make the most of your space!

Used Plastic Nesting Shipping Totes Are the Perfect Solution for Shipping Product


For companies or businesses that need to safely ship products or materials, shipping totes are a popular method of transport. These totes, which are constructed of high-quality polyurethane or HDPE plastic, are incredibly rugged, waterproof, resilient to chemicals, and will not corrode, weaken, or decompose over time. Additionally, shipping totes are much more inexpensive than their metal or wood-based shipping alternatives, making them the popular pick for businesses around the world.
From a design standpoint, plastic shipping totes rarely contain internal dunnage. This is because most shipping containers are nested, which allows them to be stacked on top of each other to save space in cramped shipping containers. Nested containers are characterized by their smooth exterior and raised sidewalls, which allows the totes to fit inside each other as you stack them.S-n Tote-2
Besides polyurethane or HDPE, shipping containers are sometimes made out of wire mesh or fiberglass, two rigid, durable materials that are slightly heavier than the aforementioned plastic types.
Pallet ContainerThe most popular types of shipping totes are from manufacturers like Akro, Buckhorn, Orbis, and Schaefer. Unlike cardboard boxes – that have a tendency to break or weaken during transit – shipping containers are long-lasting. As a consequence, buying shipping totes new or used are both excellent options. For businesses on a budget, purchasing totes secondhand over the Internet is a great way to ensure that your products or materials are transported safely without breaking the bank.
Although shipping totes are generally used for shipping materials, they are also useful as storage containers, too. The raised lip on a shipping tote makes it easy to carry, while its flat bottom allows the tote to be stored either on the ground or on a shelving unit. Like other types of plastic containers, shipping totes are capable of holding tools, materials, partially assembled parts, and paperwork.

How Industrial Totes Can Help You Organize Your Warehouse

In today’s specialized retail sector, industrial totes allow companies to maintain organization while maximizing efficiency. More specifically, industrial totes are generally used for stocking purposes in shops and stores.
These totes – which are sometimes referred to as nest totes – are capable of storing a wide range of consumer goods. Their wide-lipped design, sturdiness, and lightweight material makes the totes easy to carry, lift, and set down during the stocking process.
From a manufacturing perspective, industrial totes easily fit on a conveyor belt, allowing assembly line workers to take materials from the totes quickly and efficiently.
Industrial totes are also frequently used at distribution centers. This is because these industrial boxes, which are constructed out of polyurethane-based plastics or HDPE plastic, protect the product when they are stacked for distribution.
Depending on the tote, industrial containers sometimes have internal dunnage or plastic dividers. On other occasions, totes have nested sidewalls, which enable you to fit the totes inside each other as you stack them.
Besides their sturdiness and lightweight design, industrial totes offer a number of benefits over wooden boxes, metal containers, or cardboard boxes. First of all, cardboard boxes are not particularly durable, especially when they are being carried or moved from different locations. Plastic industrial totes, on the other hand, remain in great condition for years, even with heavy handling.
Metal containers tend to be significantly heavier than plastic totes, while wood-based boxes do not have the same versatility and ruggedness of polyurethane industrial trays.
There are currently a number of different industrial totes available on the market, both used and new. There are, for example, industrial totes made of clear plastic, which makes it easier for retail clerks to quickly determine what a tote contains during the stocking process. On the other hand, industrial totes are also made of different colored plastics that allow for color-coded organization.

The Big Benefits to Buying Used Bulk Containers Instead of New

If your company is in the business of shipping merchandise, you’re probably familiar with using bulk containers and the high costs associated with purchasing them. Buying new bulk containers can be very expensive, and unfortunately is not a viable option for all companies. A great alternative to buying new is to buy used bulk containers. There are many companies that now provide this as an option, and many benefits to buying used the next time you need containers.

Whether your company uses metal storage containers, bulk containers or industrial bins, purchasing these bins upfront and reusing them is much more cost-effective than using cardboard boxes that can only be used once. You can save even further by buying these bins used. There are many companies that will allow you to buy these used bins in bulk. Buying in bulk is one of the best ways to further bring your costs.

Not all local storage centers will allow you to buy used containers in bulk, however there are many online websites that provide this service. You can find several of these operations by doing a quick search online. These companies have a large selection of used bins available for purchase, and you can do all of your shopping from the convenience of home or at your office. By online shopping you’ll also have the opportunity to do a bit of comparison-shopping to ensure you get the best price available for your bulk containers.
In addition to saving money, another great benefit to buying used instead of new is that is cuts down on unnecessary waste and is much better for the environment. Think of all the metal, plastic and cardboard you will be keeping out of landfills by buying used shipping containers that can be reused for many years to come. You can help even further by selling your shipping containers that you no longer use, rather than throwing them out. Selling your shipping containers is another excellent way to recoup your costs.
Shipping containers are built to last for many years. Normal everyday wear and tear will not affect the usability of a shipping container. They will perform well for a long time to come, which is why it’s such a great idea to buy and sell your used shipping containers instead of discarding them. In particular, plastic containers are excellent for buying and selling used, as they are easy to maintain. They can very quickly be cleaned and are cost-effective to transport, as they are one of the lightest options available.
If you are interested in buying used bulk containers, you can find several reputable companies by looking online. Companies like Container Exchanger make it quick and simple. The listings on their website include all fees up front. They have eliminated the “middle-man” to make the purchasing process even easier. They will arrange to ship your products to you through a simplified order delivery process. Their stock includes used bulk containers, storage bins, used pallets, wire baskets and much more.

Pallet Containers and Warehousing – The important details you should know

Pallet containers are one of the most useful tools for warehouses and other storage areas because of their highly versatile nature. Before that can be explained, though, what is a pallet container and how does it work?

A pallet container is a heavy-duty storage container, usually (but not always) without a lid. Many Pallet Containers are built to be very easy to stack, and their design is usually such that they can hold a considerable amount of weight. The exact size of a pallet container may vary rather significantly, and that’s an important detail for storage. Pallet containers may be constructed out of plastic or metal, though the occasional wooden or cardboard container isn’t totally unknown.Pallet Container
However, the real importance of pallet containers is the many uses they have for businesses. Pallet containers are deliberately constructed to be mobile, and are easily transported around a warehouse floor through the use of simple transport vehicles. One of the historical problems with storing large amounts of something is that, past a certain point, it can be difficult to reach those goods. More importantly, it’s not good at all for some things to be loose and moving around, which is where pallet containers come in. When used in tandem with a sturdy frame, pallet containers can be stacked both high and deep, maximizing the amount of space a warehouse can use. In fact, compared to any location that only uses the floor, using pallet containers could double or even triple the amount of storage space a particular business has. This means that another warehouse won’t need to be rented, saving the company a significant amount of money over time.
The ability to rapidly rearrange items can also help a business prepare for a rush on a particular item; by moving things that are desired by customers to the front of the warehouse, they can be accessed much easier and cut down on the time each order takes to fulfill.
Pallet ContainersPallet containers are also excellent at holding just about anything that will fit inside of them. Some containers, for example, are excellent for holding liquids and other material that needs to be kept in a sealed container. Others make the perfect storage location for powders and similarly difficult-to-store products, though food items should only be stored in containers that are actually rated for it. However, it should be noted that only very specialized containers are suitable for storing and transporting especially large items. Pallet containers are intended for bulk storage and transportation, but large televisions and similar products may need specialized care.
If you’re considering purchasing a pallet container (or, more likely, many pallet containers), you may want to keep in mind that used pallet containers are generally just as reliable as new ones, and may cost so much less that you can afford to get more containers for the same amount of money. Whatever your general bulk storage needs may be, though, chances are that pallet containers will be the most effective option you have.

Bulk Storage Bins

Container Exchanger specializes in used metal and plastic bulk storage bins. We are experienced in selling and distributing bulk storage bins throughout the nation. We are a container supplier selling these collapsible bulk containers or rigid bulk containers to large and small companies throughout North America. Our bulk containers can take many different forms. We generally handle three types of bulk storage bins. Each type is made of a different material. We have inventories on Plastic bulk storage bins, Metal bulk storage bins, and Cardboard bulk storage bins.

Metal Bulk Storage Bins

Rigid Wire BasketThe metal version of the bulk container can be collapsible, but most often, they are rigid. We have a very nice inventory of the metal bulk containers throughout the nation, but most of the containers tend to be located in Ohio, Indiana, Michigan, Pennsylvania, Missouri, and Ontario. Metal bins are a nice and heavy duty way to handle parts within a manufacturing environment.
Rigid metal bulk bins are especially suited to any kind of metal working plant, such as metal stamping, forging, casting, etc. The rigid metal bulk containers are often suited to handle 4,000 lbs or more and can be stacked several bins high. When purcasing rigid metal containers, you may want to pay attention to the thickness of the wire mesh sides as a good indication to the capabilities of the container. We can help you find any metal bins for your manufacturing or distribution system. If you are trying to purchase additional metal containers to complement your current inventory of containers, you will need to provide us with a precise size of the container (length, width, and height). You will also need to note the mating mechanism for the metal storage bin. Pictures are most helpful in this situation, so that we can ensure that the new metal bins will be stack compatible with you existing bins.
Collapsible metal storage bins by comparison tend to be lighter duty than the rigid metal storage bins. Collapsible bins tend to be weight rated between 1,500 and 4,000 lbs. The collapsible metal bins are a nice option for a small metal shipping bin. They work well in this situation, because the sides of the container can be collapsed, thereby reducing the size of an empty container. The collapsed storage bin can be stacked in a corner of the warehouse, or they can loaded onto a trailer for return shipment to your plant.
We can find just about any bin. Follow this link to see a nice representation of our metal storage bins.

Plastic Bulk Storage Bins

The plastic version of bulk containers are almost always collapsible. Here at Container Exchanger, we call these items “Pallet Containers”. These collapsible plastic bulk containers are made from a rigid structrual foam material that is extermely strong and durable. These collapsible containers are suitable for many manufacturing applications, such as part storage a part transport. The weight capacity on collapsible plastic storage bins varies, but generally, the capacity ranges from 1,500 lbs to 2,500 lbs.Pallet Container
Collapsible bulk containers also have several size options and feature options. The sizes can be any of the following footprints:

Cardboard Bulk Storage Bins

Gaylord BoxCardboard bulk storage bins are generally referred to as Gaylord Boxes or Cratons. Most bulk cardboard boxes come from plastic injection molders, where the boxes once held raw plastic resins. Other boxes can come from storing food products, such as watermelons or lettuce. Clearly, due to the different uses for large cardboard boxes, there are many different styles, thicknesses, and weight capacities. No matter what your requirements are, purchasing used gaylord boxes can be challening. There is often more demand than supply, and significant quantities are going to be the minimum purchase amounts.
Sizes of bulk carboard boxes can vary significantly, but many boxes are sized for either 40″x48″ pallets or 45″x45″ pallets. Thickness of the boxes can range from 2 layers of cardboard all the way up to 5 layers of cardboard. The number of wall layers is a pretty good indication of the overall strength of the box, where the more layers of cardboard indicate a stronger box. However, this is not always the case, as some bulk cardboard boxes have thicker individual layers than other boxes. Some boxes are rated for a particular capacity, so it is often recommended that you inquire about this feature before purchasing a box.
Here are some things to think about before purchasing a load of used gaylord boxes:

  • How much will the product within the gaylord weigh when it is fully loaded?
  • What size of pallets do you use primarily?
  • Are you planning on stacking the gaylords?
  • Is the product in the gaylord static or dynamic (dynamic loads require stronger sidewalls)?
  • Do you need full bottoms for the boxes?
  • Do you need top flaps for the boxes?
  • Do you need lids for the boxes?

No matter what your requirements are, purchasing used gaylord boxes can be challenging. There is often more demand than supply, and significant quantities are going to be the minimum purchase amounts.
These bulk containers are not necessarily collapsible in a traditional sense, especially when they are compared to the metal and plastic collapsibles. However, they could be considered collapsible in that they are folded down flat for transport. Some businesses use these boxes over and over again, but the useful life of a cardboard collapsible container if probably about 5 uses.
Sizes of bulk cardboard boxes can vary significantly, but many boxes are sized for either 40″x48″ pallets or 45″x45″ pallets. Thickness of the boxes can range from 2 layers of cardboard all the way up to 5 layers of cardboard.
