Recycling used plastic bottles is an important means to reduce production costs and increase production efficiency. So how do you choose a variety of recycled plastic bottles? According to the type of waste plastic bottles, there are different selection points. The purchaser should select the waste plastic bottles suitable for their own enterprises according to their own characteristics.
First, the water hole material broken material. The procurement of broken materials must first be consistent with the overall quality of the materials, followed by the quality of the materials, the color, and then the purity of the materials.
Second, detergent bottles, shampoo bottles, shower gel bottles and so on. Such waste plastic bottles are more complicated, and the materials used by various manufacturers are different. The materials of such bottles include: PET, PVC, HDPE, and the like.
Such waste plastic bottles are generally opaque in color, and most of the contents of the bottles are not completely cleaned, so the processed materials are relatively low in color. It is worth mentioning that the price of such PET and PVC waste plastic bottles is relatively low. Generally, the quality of waste plastic bottles is relatively good. The purchase of bottles is the most important. The external impurities can be seen on the surface and can be estimated.
However, it is difficult to see clearly if there is no water or other impurities in it. Therefore, the procurement of bottles is more difficult, and it should be carefully checked and carefully evaluated. control risk.
Third, the milk bottle. Most of the waste plastic milk bottles are made by HDPE. Generally, just look at whether the milk inside is cleaned. Because the milk bottle is not transparent, it can't be seen if it is not cleaned. Please check carefully if it is milk. If the content is too long, it will be very stinky after a long time.
Fourth, the mineral water bottle. This kind of waste plastic bottle is relatively clean, because it is transparent, there is no water to see inside, the main thing to note is: first check if there is no mixed PVC bottle, estimate the content of PVC bottle, then look at the color, estimate the color The content of the bottle is higher as the price closer to the primary color is transparent, and the price closer to black is lower. Look at the thickness of the bottle, because some bottles are thicker, some are thinner, thicker bottles are processed faster, the materials are beautiful, and the price is high. Thin bottles have low yields and poor whiteness and low prices. Then estimate the content of other impurities.
The profit and risk of waste plastics coexist, and procurement is an important part of profit, when purchasing used plastic bottles. Must pay attention to: quality, impurities, moisture, compound, filler content, mixture, high temperature material, thermosetting plastic, color, color. Only by controlling the risks can we be in an invincible position, and only when we purchase good materials can we increase our profits.
