In modern logistics transportation, the safety and stability of goods during transit are paramount. Traditional fillers such as wooden pallets and foam plastics, while to some extent fulfilling their filling and protective roles, have numerous shortcomings in terms of cost, protective effectiveness, and environmental friendliness. With technological advancements and heightened environmental requirements, Dunnage Air Bags have emerged as an indispensable filling solution in logistics transportation.
Dunnage Air Bags, also known as container filling air bags, inflatable paper bags, kraft paper air cushions, or container cushion air bags, consist of a sturdy outer bag and an airtight inner bag equipped with a valve. The outer bag is typically made of kraft paper coated with PP (polypropylene) and PE (polyethylene), ensuring durability and reliability. The inner bag, made of LDPE (low-density polyethylene) or nylon, is a multi-layer co-extruded transparent plastic bag that maintains shape and effectively protects goods once inflated.
Dunnage Air Bags have a wide range of applications, encompassing various transportation modes such as containers, ocean shipping, trailers, and trains. During transportation, gaps often exist between goods. If these gaps are not filled, the goods may collide with each other during transit, causing packaging damage and product loss. Dunnage Air Bags fully fill these gaps, supporting the weight of goods due to shaking, absorbing vibrations, and preventing movement and collapse of goods during transportation, thereby effectively protecting them from damage.
Compared to traditional fillers, Dunnage Air Bags offer significant advantages. Firstly, their compression resistance and shock absorption performance far exceed other fillers, providing superior protection. Secondly, using Dunnage Air Bags significantly saves packing time, improves loading and unloading speeds, and enhances loading efficiency, thereby reducing transportation costs. Additionally, since inflatable bags can be reused and are easy to recycle and dispose of, they comply with environmental requirements and are favored by more and more enterprises.
When selecting and using Dunnage Air Bags, it is necessary to determine the size and quantity of the bags based on the actual situation of the goods. Generally, the size of the gaps between goods, the overall height of the goods stacked, and the depth of the pallet or the depth of the packaging size of the goods need to be measured to select the appropriate width of the inflatable bag. For example, when the gap between goods is 200mm, a 500mm-wide inflatable bag is recommended; when the gap is 300mm, an 800mm-wide inflatable bag is recommended, and so on.
Furthermore, when using Dunnage Air Bags, attention should be paid to some operational details. For instance, if the goods' packaging has sharp corners (such as wooden pallets, wooden boxes, etc.), corrugated cardboard or other flat materials should be added on both sides of the inflatable bag to protect it from being punctured. At the same time, to ensure that the inflatable bag can be reused, a label stating "For recycling, please do not damage" should be attached to the outer bag to remind the recipient to protect the bag.
In summary, Dunnage Air Bags, with their exceptional protective effectiveness, efficient loading and unloading speeds, and environmental friendliness, have become an indispensable filling solution in logistics transportation. With the rapid development of the domestic and international logistics industry and the increasing requirements for cargo packaging, the application prospects for Dunnage Air Bags will be even broader.
