|Heat Seal Bubble Mailer Bag Brown 295x435mm #J PO Antifreeze for Grocery|
|In nuclear physics, astrophysics, and in the operation of the reactor, polyethylene is used as a diffuser to measure neutrons. It made a contribution to the research of nuclear physics.
A kind of polyethylene (PE) plastic which we often use is polyethylene (PE). Polyethylene is the simplest structure of polymer, and it is also the most widely used polymer. It is made up of repeated - CH2 - unit connections. Polyethylene is formed by the addition of ethylene (CH2=CH2) to polymerization.
|Bubble mailer bag
Bubble mailer bag Is for express delivery industry,so called bubble envelope, by polyethylene bubble cover combined with PET or kraft paper , not only have the characteristics of general express plastic bags, but also has more thick buffer layer, provide higher level protection for objects in the package, in addition has heat insulation, sound insulation, moisture-proof, extrusion, impact of the advantages.
The color of the Bubble mailer bag generally pointed by the customer, mostly for the company's signature color, such as DHL generally use yellow, ups use grey, fadex with purple and orange, SF uses the gray. Uniform color express bubble bag can establish a company's professional image, highlighting the strength of the company.
Express bubble bag has a lot of characteristics, environmental protection and energy saving, it can be repeated recycling, not only save the cost, but also to protect the environment. It does not look like a disposable plastic bag, was thrown away after use, not only pollute the environment, but also increase the workload of environmental sanitation, but also a waste of energy
