Product Description

Automatic Packaging Film Bubble Mailer Bag Blue 215x260mm #E Vinyl Heat-Resistant for Shopping



Strong white plastic exterior for optimum appearance, excellent for writing&printing.

High-slip bubble lining for easy insertion.

Self-seal closure is secure and convenient


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


The core technology of the low pressure method lies in the catalyst. TiCl4-Al (C2H5) 3 body invented by German Ziegler
Polyethylene structure
As the first generation of polyolefin catalyst, the catalytic efficiency is relatively low, about tens of kilograms per gram of titanium polyethylene. In 1963 Belgium Solvay company pioneered the magnesium compounds as the carrier of the second generation catalyst, the catalytic efficiency of per gram to tens of thousands of titanium myriagram polyethylene. The second generation catalyst can also save the post treatment process of removing the residue of the catalyst. In the future, the high efficiency catalyst for gas phase method has been developed. In 1975, Italy Monte Edison group developed a catalyst which can save granulation and directly produce spherical polyethylene. It is called the third generation catalyst, and is another revolution of high-density polyethylene production.

Materials introduction
The color is yellowish, translucent and lustrous. Transparency is better than polyethylene, polypropylene, poor polystyrene, with the auxiliary dosage is different, divided into soft and hard PVC, soft products soft and tough, feel sticky, hardness of hard goods is higher than low density polyethylene, and lower than polypropylene, in the inflection place will appear whitening phenomenon. Stable; not easy to be acid and alkali corrosion; heat tolerance.
PVC has the advantages of flame retardant (flame retardant value above 40), high chemical resistance (concentrated hydrochloric acid, sulfuric acid concentration of 90%, nitric acid concentration of 60% and sodium hydroxide concentration of 20%), mechanical strength and good electrical insulation advantages.
Polyvinyl chloride has poor stability to light and heat. The softening point is 80, and it begins to decompose at 130. In the absence of heating stabilizer, PVC began to decompose at 100 degrees Celsius, and decomposed faster than 130 degrees celsius. When heated, the hydrogen chloride gas is released, and hydrogen chloride is toxic gas, which makes the color change from white to pale yellow to red to brown to black. Ultraviolet rays and oxygen in the sun will cause the decomposition of polyvinyl chloride, which makes the flexibility of polyvinyl chloride decrease and finally become brittle. From here, it is not difficult to understand why some PVC plastic will become yellow and brittle for a long time.
