Packing peanuts, also known as foam peanuts, foam popcorn, or packing noodles, are a common loose-fill packaging and cushioning material used to prevent damage to fragile objects during shipping. They are shaped to interlock when compressed and free flow when not compressed.
In logistics, the term “custom dunnage” describes packaging designed to specific dimensions to protect fragile items during shipment better. This type of dunnage is often used for high-value or sensitive items, providing an extra layer of protection.
Custom dunnage can be made from various materials, including foam, plastics, and even metal. The choice of material will depend on the items you’re shipping and the required level of protection. For example, items susceptible to corrosion may require metal dunnage, while delicate electronics might be best protected by foam padding.
In some cases, custom dunnage may even be required by law or regulation. For example, shippers must ship certain types of medical equipment in padded containers that meet specific standards.
Benefits and Uses Dunnage
When it comes to shipping, dunnages are often an afterthought. But many shippers need to realize that dunnage can provide several benefits for their shipments.
From damage protection to shock absorption, dunnage can help ensure that shipments arrive at their destination in the same condition they left in. Here are five ways that dunnage can benefit your shipments:
While dunnage fills space, it also plays an essential role in protecting fragile items from damage. For example, corner protectors can help prevent goods from being crushed during transit, while foam padding can help absorb shock and avoid breakage.
In addition, dunnage can also keep goods from shifting around during transit, which can help to reduce the risk of damage. As a result, using dunnage is essential to ensure that goods arrive at their destination in perfect condition.
Moisture and Contamination Protection
Dunnage helps to keep cargo from shifting during transit, preventing damage to the shipment and the container itself. In addition, floor dunnage can protect from moisture and contamination. By absorbing moisture and protecting against spills, dunnage helps to keep cargo clean and dry.
As a result, it is an essential component of any safe and effective shipping operation. Dunnage is relatively inexpensive and easy to procure, making it a wise investment for any business that ships merchandise regularly.
When it comes to preventing damage during shipping, one of the most important things to consider is shock absorption. Airbags are the most effective shock-absorbing dunnage. Airbags are inflated with compressed air and then placed between the load and the walls of the container.
They act as cushions, absorbing shocks and vibrations and keeping the contents safe. In addition to protecting against physical damage, airbags help prevent moisture damage by creating a barrier between the load and the outside environment.
As a result, using dunnage can be an effective way to protect your shipment from damage.
Easy Handling of Heavy Items
One of the significant benefits of dunnage is that it makes it much easier to handle heavy items. By filling in the gaps between the items, dunnage prevents them from shifting around during transport.
This makes it much easier for workers to load and unload the items since they don’t have to worry about them moving around. Additionally, dunnage can help to protect delicate items from damage during shipping.
Cushioning the items and preventing them from moving around helps prevent scratches, dents, and other forms of damage.
Another benefit of dunnage is that it helps to improve air circulation. Air circulation is crucial in the case of food storage, as poor air circulation can lead to spoilage.
By using dunnage to create gaps between containers, organizations can ensure that air can circulate freely and that food stays fresh for longer. This improved airflow also helps to prevent mold and mildew from forming, which can cause significant damage to stored goods.
Is Dunnage Reusable?
Dunnage is reusable if it can withstand being used multiple times without losing its effectiveness. There are different types of dunnage; some are more reusable than others.
Air cushions, for example, are often used as reusable dunnage because they are lightweight, have high strength, and have an unprecedented capacity to absorb vibrations.
Cardboard boxes and wood pallets are also common types of reusable dunnage. Generally, any dunnage that is durable and can be reused multiple times without losing its usefulness is considered reusable.
Alternate Types of Primary Packaging
In addition to dunnage, two other types of primary packaging options are available: component packs and unit loads. Component packs are tinier packs that protect individual components within a product.
For example, you may individually wrap electronic components in component packs to prevent them from being damaged during shipping. On the other hand, unit loads are larger packages that consolidate multiple products into a single shipment.
For example, a pallet of bricks would be considered a unit load. As a result, manufacturers can reduce the number of shipments by using unit loads, saving time and money.
Kit packaging is a type of packaging where several similar items are put together into one box and delivered to recipients. This type of packaging is often used for products that need to be shipped in bulk, such as food kits or medical supplies.
Kit packaging can also be used for promotional purposes, such as when a company sends out free samples of its product. When done correctly, kit packaging can be an efficient and cost-effective way to ship products.
However, if not done carefully, kit packaging can result in damaged goods or lost items. For this reason, working with an experienced and reputable kit packer is vital when using this type of packaging.
Multi-material packaging is a type of packaging constructed from a single material or a few different components, such as paper, plastic, and aluminum foil.
This type of packaging is often used for food and beverage products, as it can protect against moisture, oxygen, and other contamination. Multi-material packaging can also be more durable than single-material packaging, making it ideal for products that require extended shelf life.
In addition, multi-material packaging can create unique product designs that are visually appealing and functional. However, one drawback of multi-material packaging is that it can be more difficult to recycle than single-material packaging.
As a result, companies that use this type of packaging need to dispose of or recycle the materials properly.
