Customized plastic bags to measure what size? How to measure? Customized plastic bags to measure what size? How to measure? When custom-built plastic bags, it is need to plastic bag manufacturers to provide the size of the plastic bags, so in the case of a sample, what size should be measured? And should be how to measure? First of all should be the basis of measurement packet size: wide ( Opening) , long, side. Opening width and length of bag, the bag side thickness, the three data is the basis of the packaging, of course, these are not enough. Second, the need to measure the thickness of the bag, usually measure the thickness of single layer packet. Measuring the thickness of the thickness gauge is used, usually without thickness gauge only by the size to calculate the thickness of the bearing combination products. Finally, part of the packaging bags have some details size also need to measure, such as distance from the edge of the printing design, etc. Plastic thickness measurement method is to introduce a film thickness gauge is used to measure the paper, plastic film class of items have special thickness gauge, using the thickness gauge can measure the thickness of the plastic bags, generally the thickness of the plastic bag is in 2. Five between 15 silk, silk is 0. 025mm- 0. 15mm。 Because in 2008 countries issued plastic limit, plastic limit state regulations, plastic shopping bags to reach zero. 025 ( Monolayer film) Above, upon the thickness was known as the environmental protection shopping bag, below the thickness is called & other; Thin bags & throughout; Or & other Ultra-thin bags & throughout; 。 In fact, the thickness of the plastic bag can be custom-made, from 0. 0075 mm to zero. 15 mm can be produced. Plastic bag size can be customized, customized according to user demand, there is no fixed size. According to the width of the plastic bags of chopsticks says only two centimeters wide, the plastic bags can reach 2000 mm wide, range is large enough. Plastic film thickness gauge: 2 by weighing calculated fuzzy estimate if don't have film thickness gauge, to get the thickness of the plastic bags data, load method can be used. Is to use precision at least 0. 01 g electronic scale according to the weight of the plastic bag, then by dimension data to calculate the thickness of the plastic bags. Plastic bags computation formula is as follows: the weight of the plastic bag weight = long & times; ( Wide + side) × 2× The density of material & times; Thickness so can get a calculating formula for the thickness of the plastic bags, plastic bags thickness = weight/plastic bags ( Long & times; ( Wide + side) × 2× Material density) But only vague was calculated by the formula to estimate the thickness of the plastic bags, usually there will be zero. 01 mm - 0. 02 mm error, because the weight of the plastic bag printing ink and the size precision of the control problem of production will have an effect on the final calculated results, so generally use thickness gauge measurements are accurate. Measuring the thickness of the plastic bags: content extension 1 how to find the experienced old factory? When you after baidu or alibaba search keywords to find plastic bag manufacturers, how to comb through the experienced old factory? Here provides a method: you can copy the name of the manufacturer to the eye to check or company check of manufacturer data, registered capital and fixed number of year, you can see the following thought case 2 as a plastic bag manufacturers, have what advantage? As the packing bag of 20 years of experience factory, the factory is located in longgang district JiHua street, is a one-stop packaging manufacturers, production of plastic bags and non-woven bags, blown film, printing, bag making control all by themselves, stable quality, prompt delivery. Business scope extensive, can produce including plastic bag, flat bag, zipper bag, as self-adhesive bags, Courier bags, non-woven bags and other products, has many years of cooperative relations with many domestic brands.
