LDPE (Chinese Name: Low Density High Pressure Polyethylene): Sensory Recognition: Soft Hand: White Transparent, but General Transparency, Combustion Recognition: Flame Yellow under Blue; Smokeless when burning, with the smell of paraffin, meltable droplets, easy to pull out, generally LDPE molecular weight distribution is narrow, with linear structure, so that It has different rheological properties. PE has excellent tolerance to most household and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halides (carbon tetrachloride). The polymer does not absorb moisture and has good waterproof steam. It can be used for packaging.
How many functions do you know about bubble bags?
Non-toxic, tasteless, moisture-proof, corrosion-resistant 2. 3. Sound proof, shock proof and abrasion resistance. Light weight, good transparency and elasticity.
Use bubble bag:
Anti-static air cushion film, used for packaging electronic components, such as boards, cards and other components, can prevent static electricity, play a cushioning and shock-proof role. Two
Bubble bag can be made into bubble bag, bubble kraft paper envelope bag, automobile sunshade, heat insulation cushion, heat insulation material and other bubble bag storage and use and maintenance methods (1) Bubble bag should be stored in the warehouse to avoid sunshine and rain; No contact with acid and alkali, oil, organic solvents, keep clean and dry, found from equipment 1 m, room temperature 15 C to 40 C. The temperature (2) foam bags should be placed in the rolls, not wrinkled. When the storage time is too long, it should be turned over for a quarter (3) when the loading and unloading conveyor belt is used by the crane, and a bunch of manipulating is smooth, to avoid favoring any side and not to arbitrarily load and unload, resulting in loose coil sleeve bubble bag main application areas. Mainly used for the packaging of postal products. Bubble bag additional damping foam film, with small bubbles in the foam packaging, so the body is light, elastic, sound insulation, shockproof, scratch resistant, widely used in electronics, tools, ceramics, handicrafts, household appliances, dealers, kitchen, furniture, hardware products, glass products and precision instruments, such as buffering vibration resistance, protective package. Install. It can prevent the goods from being squeezed, vibrated and frictioned in the course of transportation, and has a certain protective effect on the goods. In addition, by adding different additives to the raw materials, various special bubble bags, such as anti-static, can be produced. Anti-static air cushion bag is used for packaging electronic components, such as integrated circuit board, card, etc.
