Loose filling

To fill the empty space of lightweight items. Advocate against using such internal packaging for flat, narrow, or tightly packed products that may move within the package. Because loose fillers may cause displacement or sinking during delivery, the product may move within the package and may be damaged. When using loose filling materials, fill each side of the container with less than 2 inches (5.08 centimeters) of material. In addition, the filling height should be slightly higher than the package to allow for displacement and sinking. Loose filling materials, such as expanded polystyrene filling blocks, can cause static electricity and damage electronic devices. Electronic items should use anti-static filling blocks. Using plastic bags, bubble wrap, or other materials to wrap items can prevent filling blocks from entering areas that may damage the product.

Compressed air sheet

It is a packaging material that seals air bubbles between two polyethylene sheets. This kind of closure is achieved through the formation of bubbles to form a soft cushion and achieve seismic resistance. Compressed air sheets can provide cushioning for lightweight items, have good flexibility, and can be used to package products of any shape or size after selection. But not suitable for packaging heavy products. When using compressed air sheets, please use multi-layer packaging to ensure that the entire product (including edges and corners) is protected.

Polyethylene foam sheet

The foam sheet material is light, soft, elastic, and has the characteristics of surface protection and cushioning. It is an ambitious choice to protect light goods.

Inflatable bag

Inflatable bags use air pressure to secure products inside shipping containers, forming an air cushion with cushioning function. But in the climate environment, the pressure inside the bag will be negatively affected. In cold conditions, the amount of air will decrease, resulting in more empty space inside the package, and the product is more likely to be damaged. Under hot conditions, the airbag will expand, creating pressure on the seams of the transport container.

Changes in altitude can also affect the amount of air inside the airbag. Transporting from high-altitude areas to low altitude areas (such as packaging goods in Denver, Colorado, and then transporting them to New Orleans and Louisiana) will result in a decrease in airbag size, while transporting from low altitude areas to high-altitude areas will increase airbag volume.

Field foam/foam filling bag

Field foam/foam filled bags are made of a chemical mixture that expands and forms a protective layer around the item. On site foaming can form a model around the product, playing a role in supporting corners, protecting edges, and buffering. To achieve the desired effect, on-site foaming must be evenly distributed around the object. Otherwise, foam will not protect product supply. In order to meet the demand for packaging, please select foam with proper density, which can be used from filling to buffering.

kraft paper

Kraft paper (not newspapers or newspapers) can be used to wrap items, and can also be folded and used to fill empty spaces for wrapping (containing light or medium non fragile items). When using kraft paper, it should be tightly filled between and around the goods, with a minimum filling of 2 inches (5.08 centimeters). Please ensure that all six sides of the packaging box are filled with at least 2 inches (5.08 centimeters) of kraft paper.

Paper buffer material

Multilayer paper (not newspapers or newspapers) is an ideal filling material, especially suitable for packaging medium and large non fragile items and items that require moisture absorption. Paper buffers are very suitable for filling empty spaces.

Expanded polystyrene foam (EPS)

EPS can be molded, with light weight, low cost, and buffering ability. EPS is generally designed as a rib shaped structure, which will shorten and return to its original shape when impacted. Its elasticity is not as good as other polymeric foam, such as polyethylene and polyurethane. EPS is suitable for non fragile goods.

Polyethylene foam (PE)

PE is a kind of foam plastic. PE molded or assembled has superior impact and vibration resistance, making it a suitable choice for providing cushioning for high-value or fragile items.

Polyurethane foam (PU)

Polyurethane is a kind of elastic foam with impact absorption and shape recovery ability. Because it is light and elastic, it is more suitable for light goods.

corrugated board

Two or more layers of single wall or double wall corrugated cardboard are adhered together to form a barrier or liner. These pads can form a protective layer between the product and the container. Corrugated liners are used for heavy-duty, semi fragile, or non fragile products. Corrugated board can be used to make pallets, liners, baffles, and other wrapping accessories, providing cushioning for semi fragile or non fragile products and adding integrity to shipping containers.
