Winter to, we all know that this thing to the plastic after the winter will become very brittle, what is the reason?

Plastic is the main component of macromolecular aggregates, macromolecules characterized by low temperature when the slow movement, high temperature, fast movement. In the winter, the molecular movement is slow, when the plastic by external force, the object deformation, due to molecular motion is slow, external force is not easy to pass away (equalize internal stress) or consumed (molecular chain friction), so prone to stress concentration, When the internal stress to a certain extent, the macromolecules on the broken, triggering cracks, cracks will be cited stress concentration and dissemination of plastic on the broken.

Approach: In general, a small amount of moisture injected into the bag can reduce the fracture
