There is no significant difference in the shape of PET plastic box and PVC plastic box. PET blister boxes and PVC blister boxes commonly use transparent film. The background color of some materials may be blue or yellow. Generally speaking, PVC will be blue, and the background color of PET will be white or slightly yellow. But this is not a standard, nor is it a scientific way of judging. PET and PVC film can be customized according to requirements, and the background color of the film can be adjusted manually. A more reliable way to judge is to use combustion to distinguish between the two materials. Because PET is an environmentally friendly material, it does not require additional combustion aids, and it will also burn. But PVC is different. Whether it can burn is the easiest way to judge PET and PVC.

The material introduction of PET blister box and PVC blister box is introduced from the most primitive and simple way above. In most cases, these two materials can be used interchangeably. For example, in some cases, as long as it is not too small or the buckle is very tight, the plastic blister produced by PET plastic box packaging and PVC film, if you leave out the materials, there is almost no difference in appearance and use experience.

The difference in experience between PET blister boxes and PVC blister boxes will appear in some specific situations. The smoothness of the PET surface is very good, and PVC is superior to PET in terms of toughness. These characteristics are advantages in some cases, but in inappropriate cases, it makes some of the characteristics of the material a fatal weakness. The correct use of these two materials is the most basic and most important technical requirement of the plastics industry. The physical characteristics are too rigid and easy to fold, and PET fully meets this physical description. The hardness of PET film is better than that of PVC. The blister trays and blister boxes produced have a very good feel on the hand: they are strong and give a solid and durable feel. Utilizing the rigid characteristics of PET should be just right. In some specific use environments, if the load-bearing or impact force in the use environment has exceeded the impact resistance of the blister itself, then the PET blister tray will break. In this use case, although the PVC blister tray is less rigid than PET, it may be more suitable for this working environment.
