Today we Ningbo Pacific Packaging Belt Co., Ltd. to bring you a packaging belt procurement knowledge. We are the industrial production of PP packing belt, baler manufacturers.
The packaging belt industry has experienced the development of more than 30 years, the quality of the packaging belt on the market is uneven, the price from dozens of yuan to hundreds of yuan. In the procurement process, enterprises often only pay attention to the ton price, but ignore the actual length of each ton of packing belt. This deformity of the concept has also affected a part of the packing belt manufacturers, the market appeared sandwich packing belt, ton bag packing belt, raw material packing belt and other cheap and thick belt.
But the sandwich packing belt, ton bag packing belt, recycled material packing belt has a very low breaking strength, poor bonding strength, which affects the packaging quality of products. So, how do we distinguish the quality of the packing belt when we purchase the packing belt?
How to distinguish "new belt" from "plastic belt"
A brand new belt is made of 100% raw plastic material, which is the most efficient, but also the most expensive. The plastic tape is also made of 100% plastic, but is made entirely or partially of recycled plastic. So how do you tell if the straps are made of brand new material?
By the look. The packaging belt made of new materials is more beautiful, its material is transparent, and the color and lustre are uniform. For example, we can put a piece of written paper on the desk and put a piece of fresh material tape on top of the paper, and then we can see the words underneath the tape clearly, whereas the tape made of recycled material does not have this effect.
Next, distinguish from the feel. The packing belt made of new material has good rebound force, good hardness and thickness. We can compare the packing belt made of 100% new material with the packing belt mixed with recycled material. By stretching it in the opposite direction with our fingers, we can find that the packing belt made of 100% new material has a strong restoring force, while the packing belt made of recycled material is not hard enough, so the restoring force is not so good.
Again, one of the best ways to distinguish by experiment is by fire. The packing belt made of 100% new material will not have pungent smell when burned. The residual ash is crystal. The tape containing the recycled material will have an unpleasant pungent smell when burned, and the ash will contain other substances, such as lime.
