Dunnage bag can prevent the movement of goods being transported in the trucks, containers or railway transportation. It can fully fill the gap among cargo/goods, support the weight result from the swagging of the cargo/goods, and absorb the shake to protect cargo from damage during transportation. It is better than other supporter or filling-in, and better for protecting environment than the traditional methods, such as foam, plastic products, and so on.
Outside the Dunnage bag is made of PP and PE film faced kraft paper solid and tough. Inside is made by 5 layers PE crowded membrane. One-way valve inflated and deflated quickly, firmly closed, and can support more than 5 tons of pressure.
Dunnage bag not only has low-cost, but the resistance and shock-absorbing properties are far superior to other fillers. The easily use Dunnage bag can save packing time, lower transport costs and improve the image of the company. More and more companies have recognized and made good use of Dunnage bags.
Before the appearance of the Dunnage bag, wood trays and foam were widely used to fill the gap among the cargo. However, these materials are unsatisfactory in cost and protecting effectiveness, and are subject to some restrictions. With the increasing requirements of environmental protection, wood / foam-filled, and other materials are being discarded.
Now, Dunnage bags are widely used by electronic, IT, chemical, mechanical and electrical, medical, agricultural products, and other industries.
