Cushioning materials – usage, types, and other info


Cushioning is an element or method used to lessen the injury, shakes, or both that give a packaged goods from an external unit. To cushion, a substance must diverge upon collision. This deflection provides the cushioned thing to decrease its rapidity to zero over a more extended period than it would if it were not diminished.  Cushioning is flexible, indicating the element can distort yet respond to the same degree of shock compression given on the early force.

Cushioning acts as a shock absorber to stop harm to the stock. The cushion lessens the acceleration-time vibration, decreasing the acceleration and expanding it over a more extended period.

Scope of utilizing cushioning materials

Goods are usually carried that are especially susceptible to mechanical forces and must consequently be shielded from loss due to collision, jolting, or wave in transportation. They are thus additionally guarded by cushioning materials inside the transportation packaging.

Delicate goods, such as glass, ceramics, earthenware, or tender electronic commodities, such as processors and electronic home entertainment devices, are especially receptive to mechanical forces and should be guarded.

In addition to defending the case contents, cushioning materials may also alter the sets to a regular dimension. They serve as adapters between nonstandard box contents and the packaging modularity of shipping packages.

Essential features of cushioning materials

 Cushioning materials must satisfy main elements:

  • Restoration is one of the basic features of a cushioning material; it guarantees that the box contents remain preserved even when regularly constrained to similar pressures. If repair is too low, the braking distance declines on constant exposure to stress, such that the resultant kinetic force can no longer sufficiently be grasped, and the package contents may be maligned.
  • Cushioning materials must be indifferent to weather situations, such as damp due to high comparative moisture, straight cosmic transmission, and progressive changes in temperature, and their performance must not be damaged by such exposure.
  • Particularly in the case of case contents that are at hazard of corrosion, it is necessary that the cushioning materials are not hygroscopic and consequently do not develop rust. They should moreover not include any destructive elements (neutral pH), which could add to corrosion. The cushioning material and package contents should not mix and perhaps break each other’s resources.

Classification of various kinds of cushioning materials


Airbags consist of a flexible film that is expanded with air. When at rest, only the latent load caused by the weight of the box contents shows upon the cushioning. When dynamic pressures happen, these are consumed by confining of the cushion. Airbags are mainly utilized in vessels and railroad transportation cars and only seldom in trucks.

 Advantages of airbags:

  • Efficiency of administration
  • Nonhygroscopic
  • Highly accomplished
  • Mainly indifferent to severe climatic circumstances (heat, cold)
  • High restoration and excellent shock absorption qualities

The disadvantage of airbags:

  • Sensitive to tapered and sharp objects, such as nails or the like

Bubble films

Bubble films work in basically the same process as airbags. They consist of two plastic films, one of which is completely even and the other has small, curled sections, which, once the two films have been heating sealed collectively, include the required air. Bubble films are mainly used internal packaging vessels. The advantages and disadvantages are the same as for airbags.

Rubberized fiber cushioning

Rubberized fiber cushioning gives high-quality protection for requiring things. This softening is made from animal hair or coconut surface turned into nonwoven covers, covered with rubber, and welded to form solidly bonded layers. Rubberized fiber cushioning is relatively indifferent to the consequences of dampness and high or low heats and shows remarkable improvement even on long-term display to contents.

Plastic foam cushioning materials

Plastic foam cushioning materials are mostly made from polystyrene (PS), polyurethane (PU), and polyethylene (PE). Plastic foams are open in flexible, semi-rigid, and stiff forms. Their cushioning uniqueness is determined not only by their exact load but also by their cell formation.
