|Single Web Stand Up Bubble Mailer Bag Cyan 145x210mm #C PET Uv Proof for Candy|
|In 1933, the British ICI company found that ethylene can polymerize into polyethylene under high pressure. This method was industrialised in 1939, known as the high pressure method. In 1953, the Federal German K. Ziegler found that TiCl4-Al (C2H5) 3 was a catalyst and ethylene could be polymerized at lower pressure. This method was industrialized in 1955 by the Hearst Co of the Federal Republic of Germany, known as the low pressure polyethylene|
|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
