PET green cosmetics packaging aluminum tube identification method is introduced

PET green cosmetics packaging aluminum tube identification method is introduced of the PET, Chinese polyester, normally we operate many people call it polyester. Generally PET waste plastics industry to do the most is a bottle of tablets, including all kinds of coke bottle, mineral water bottles, eye cream, environmental protection, such as cosmetics packaging aluminum tubes. Bottle flakes classification: imported bottles generally divided into: 1, net piece that is clean without impurities (do not contain PVC or PVC Polyvinyl chloride (PVC) No more than three over one thousand including moisture are extra. Net including white pills ( The colorless transparent bottle crushing material) , white, blue, white and blue green pills ( Commonly known as the three color) Green films, the highest noise, price to white pills, and so on. 2, rushes included environmental protection cosmetics packaging aluminum soft pipe wrapping paper and the shattering of the cap, there are only contains rushes of wrapping paper. This is relatively good. Rushes there are clean and not clean, in general, Japan and Taiwan rushes cleaner, German or European porn doesn't seem to have been cleaned. The most general rushes is 20% of the impurity. Should be in 10 - but most rushes 12% point impurities. Japan there are fairly good, only 5% impurities, this depends on environmental protection cosmetics packaging aluminum hose manufacturer. Wool prices, if in the same situation is also in accordance with the net color classification. Bottles of indicators and identify the first manufacturer of indicators was a result of different purposes of different requirements. Bottle blowing factory requirements of the indicators is the melting point of 250 degrees viscosity of 0. More than 7 and not a little impurity. Staple factory requirements of the indicators is the melting point of 250 degrees viscosity of 0. Can be seen more than 6 bottle blowing factory requirements quite high, but from last year, they used to price advantage, and now the basic all shipments to the waste-water. How to identify the goods in the index. Generally if require very accurate will be sent to special inspection organizations, such as I have been to the Shanghai chemical plant inspection, such data is the most accurate. But if we look at the scene goods only by simple measuring instrument. 1, first smell, the taste of PET different general plastics. Use lighter to burn, then smell is very fragrant and comfortable ( Literally burn a bottle to smell) , if the PET to contain other ingredients, the taste is very pungent. There is a bottle containing the composition of SEBS can't use. 2, see burning section, if too much black or oil droplets soon, most of the melting point is not normal, the PET film in common. 3, drawing, burning on the lighter when a pull wire, wire pull long is not long, and then pull out the wire break, look at the middle of the breakpoints, silk is rolled into the small circle, the more volume of high melting point. But generally if it is a bottle of tablets, should not have much of a problem. The key point! Is to distinguish whether contain PVC, it's a PET's Achilles' heel. Multiple sampling first, and then spread in sunny places, PVC light blue in the sunshine. If there will be a white crease of folded in half. Above, is visible to the naked eye identification accuracy is limited, mainly the experience. There are better practical ways. Buy an oven. The thermostat at 250 degrees bake there half an hour. If goods contain PVC, the surface will have a lot of yellow spots. If the melting point will melt quickly enough.
