PVC box transparent box can be divided into soft PVC box transparent box and hard PVC box transparent box. Among them, the hard PVC box transparent box accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used on the surface of floors, ceilings, and leather, but because soft PVC packaging boxes contain softeners (this is also the difference between soft PVC packaging boxes and hard PVC packaging boxes), it is easy to become brittle and not easy to use. Saved, so its scope of use is limited. Hard PVC box transparent box does not contain softener, so it is flexible, easy to mold, not easy to be brittle, non-toxic, no pollution, long storage time, so it has great development and application value. The PVC used in wine boxes is now hard PVC. Therefore, people who use red wine boxes should also have certain identification methods.
