we often need to estimate the amount of polyethylene tape engineering material, but after we confirmed the polyethylene tape specifications, can according to the area of material proportion to calculate the weight polyethylene tape procurement, so we must get accurate material proportion of the data, it is a very important data. When we know the area of polyolefins adhesive tapes required, we can according to the proportion to calculate the weight of polyethylene tape required. Or when we know the number of polyethylene tape and the thickness, we can calculate the material of construction area. In a word, polyethylene tape area with weight coefficient, is a very important data. So this data is how many? And what is the conversion formula between area and weight?

in polyolefin tape industry, the size and weight coefficient of polyethylene tape in general is 1. About 2. The weight of the calculation formula is: tape per unit area ( kg) = the thickness of the adhesive tape (per unit area mm) * 1. 2. Such as 0. 7 mm thickness of adhesive tape, a square tape is commonly 0. 84 kilograms. Between the size and weight coefficient is related to the ratio of raw material with polyethylene adhesive tape. Other such simple computation is applicable to complex internal and external belt of polyethylene tape, together with the current is not suitable. General shape polyethylene tape is direct purchasing according to area.

polyethylene tape generally consists of polyvinyl membrane and rubber. Polyvinyl membrane made from high density polyethylene materials and low density polyethylene material. High density polyethylene of polyethylene tape tensile strength and elongation at break. High density polyethylene to add, the more the elongation at break of the product is, the better, the easier products stretch. But the impact resistance and tensile strength of the product is the corresponding lower, the greater the coefficient.

low density polyethylene and high density polyethylene just the opposite. It and impact resistance and tensile strength of the product. Low density polyethylene add, the more the impact resistance and tensile strength of the product is better, but the elongation at break of the product is the lower. The less the coefficient.

in order to better improve the performance of products, high and low density polyethylene to be carried out in accordance with the reasonable proportion of added. So the coefficient of polyethylene tape is 1. About 2. In addition, the size of the coefficient is related to the base film and the proportion of the thickness of the rubber. Differences between different specifications of polyethylene tape.
