Not so long ago, a new material could be seen on the domestic market of packaging materials - polyethylene foam. It has unique performance characteristics that have allowed it to become quite a popular packaging material. He was appreciated by both construction professionals and ordinary amateurs.
What is he like?
Polyethylene of this group perfectly copes with its functions as a cushioning and packaging material. Typically, such functions are needed in situations where product transportation is being established. Foamed polyethylene provides additional protection for the cargo from dirt, moisture and mechanical damage. Bubble wrap is often used with it to increase protection when it's really needed.
Features of the material and its varieties
To obtain a material such as polyethylene foam, polymerization is organized for ordinary ethylene. As a result of thisprocedure, the material partially crystallizes. It is thanks to the acquisition of such a structure that the material retains moisture even at 130 degrees, and also more successfully resists environmental influences.
Types of material by physical properties
Physically cross-linked and chemically cross-linked - in this embodiment, foamed polyethylene is presented on the modern market. If we are talking about packaging, then with a high probability it will be physically crosslinked polyethylene. The thickness range of this variety can vary from five tenths to twenty millimeters. Although variations in density remain small. So that each consumer can become the owner of the optimal packaging that meets the specific requirements of a particular person.
About characteristic features
There are a number of characteristics that make polyethylene foam so popular. The price of the material will directly depend on the quality. So, characteristics:
- non-allergenic, environmentally friendly;
- durability and durability;
- insensitive to temperature changes;
- low abrasive;
- excellent cushioning properties;
- resistance to deformation;
- low thermal conductivity;
- water resistant;
- flexibility, firmness and elasticity.
Rodents and insects do no harm to such material. fungus, mold andchemical exposure is also not dangerous. The closed cellular structure is one of the main features of a material such as polyethylene foam. The thickness of the material has almost no effect on its excellent ability to become a good insulator and the ability to keep moisture and steam out, even in large quantities. If, during loading, technical debris gets on the surface or somewhere nearby, then it is the foamed polyethylene that will take on these substances. Therefore, the product itself will not be exposed to mechanical damage.
