Q:What material do you need for plastic film? Do you use this material?

In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements. But this plastic bag is made from recycled material, which is environmentally friendly, and the price is 10% to 50% lower than that of the new material bag

Q:Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?

The blowing ratio is one of the control points of blown film production and! Refers to the ratio between the bubble diameter and the diameter of not blowing blowing after.

Q:Do you have plastic materials that are low in price instead of ABS?

The H series of PP sells for only $13.5, and /KG and ABS are lower.

Q:PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?

PE bellows formulations generally include the main resin, additives and fillers, in which the resin polymer in the infrared spectrum of the difference, the plastic material can be judged by analysis.

Q:How to identify the proportion of nozzle material in plastic?

This result has two conclusions: 1, with large ratio of feed back. 2, the molding process causes the plastic cracking phenomenon to be more serious. The following is a screenshot of the performance of the material. It is important to note that the same plastic has different data downstream of different test conditions, so it is necessary to refer to the test conditions on the physical chart.

Q:Will plastic raw materials (such as PET, PP, etc.) be made of non-woven fabrics, will certainly contain BPA?

BPA is an additive, and plastic products are usually added! If it is a recycled PP material, the genus will contain

Q:What material is plastic bag made of?

HDPE-- HDPE high density polyethylene, referred to as HDPE. The density is 0.941 to 0.965g/ cubic centimeters. It is made of low pressure polymerization, so it is also called low-pressure polyethylene. Milky white, indicating poor luster. The machined films can be blown by blow molding and T die extrusion. Heat resistant, resistant to cooking, cold resistant, resistant to freezing, moisture resistant, gas proof and isolating, it is not easy to be damaged, and the strength is two times of LDPE. Easy opening. The paper is strong and is called "paper - making plastic film"". BOPP-- of BOPP biaxially oriented polypropylene film, also known as BOPP film, English abbreviation code BOPP, characterized by stretching molecular orientation, mechanical strength, folding strength, air tightness, moisture barrier property is better than ordinary plastic film. The unit price is lower than that of cellophane. Because of the excellent transparency of the film, the post press reproduction is especially bright and beautiful. It is an important base material for plastic composite flexible packaging

Q:Pollution in the production of plastic raw materials from petroleum production

Petroleum - intermediate - polymerization monomer - resin - plastic particles - plastic products, the process of the above, each will have pollutants!

Q:What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc

PA66 (polyamide 66 or nylon 66) is more widely used in the automotive industry, instrument shells, and other products that require impact resistance and high strength than PA6, PA66.

Q:What is the material of plastic flat screen?

Plastic flat net (also known as plastic breeding net) is plastic material in the extruder heating melting through the extrusion into a special rotating head is provided with a plurality of holes inside and outside of the die, the molten plastic flowing through the die pore forming two shares melt silk, because of head rotation, two shares converge to a continuous filament thus, the formation of network, after cooling into the net.
