Differences between the two applications, LDPE MDPE HDPE, PP woven and non-woven bags

On the other hand, LDPE LDPE (low density polyethylene) from ethylene gas is very high (up to about 350 megapascals, or 50,000 pounds per square inch) of pressure and high temperature (up to about 350 ° C [660 ° F ] prepared under) oxide The presence of the initiative. These processes produce both long and short branches with the structure of the polymer. Because the branches are hard, hard, crystalline packing closely together to prevent the molecules of polyethylene woven bags, LDPE material is very flexible. The melting point of about 110 ° C (230 ° F).

MDPE (medium density polyethylene), LDPE and HDPE are in the mix.

Other materials, pp. tissues (tissue polipropilinani), pp. sheet great that the long-term trends of cutting and then woven together to make a sheet of woven material made by extrusion. Strength, cost-effectiveness and character with ventilation holes, PP woven material is also flexible packaging material for food.

In fact, with different characters, each material has different characteristics and can be used for various functions.

As materials are used for various purposes, the production of the packaging bag

LDPE material that is soft, smooth and shiny for the production of quality luxury bags, watches, clothes, bags, etc. However, suitable for packaging, due to its quality, LDPE virgin material cost is quite high, which is a challenge for a small business. Therefore, they are a manufacturer of recycled materials, as well as adding to the cost reduction can suggest is make bags ecological.

HDPE however, is of high quality, low cost and the size of the hard material is a popular choice for many companies. Furthermore, HDPE, the manufacturer to produce with a thin thickness, materials suitable for different types of instruments. However, to compare the contents of LDPE, HDPE and LDPE soft as not polished, therefore, industrial products, food products and foodstuffs, etc.
