PET blister and PVC blister have no significant difference in appearance. PET blister and PVC blister boxes are commonly used for transparencies. Some materials have a base color that is either bluish or yellowish. Generally, PVC will be biased toward blue, and the background color of PET will be white or slightly yellow. But this is not an absolute standard, nor is it a scientific way of distinguishing. PET and PVC film can be customized according to requirements, and the background color of the film can be artificially regulated. A more reliable way of judging, the two methods can be distinguished by burning. PET is an environmentally friendly material and does not require additional combustion aids. It also produces combustion. PVC is different, and whether it can be burned is the easiest way to judge PET and PVC.

        The above describes the PET blister, PVC blister material distinction from the most primitive and simple way. In most cases, these two materials can be used interchangeably. For example, in some cases, if it is not too small or the buckle is very tight, the blister produced by PET blister packaging and PVC film, if there is no material to be removed, there is almost no difference in appearance and experience.

        The difference in the experience of using the PET blister box and the PVC blister will appear in some specific situations. The smoothness of the PET surface is very good, and PVC is superior to PET in toughness. These characteristics are advantages in some cases, but in some cases, the characteristics of some materials become fatal weaknesses. The use of these two materials is the most basic and important technical requirement of the plastics industry. The physical characteristics are just too easy to fold, and PET fully conforms to this physical description. The hardness of PET film is better than that of PVC. The blister tray produced by the blister film has a very good experience on the hand: the firmness gives the user a solid and durable feel. The characteristics of the rigid PET are just right. In some specific environments, if the load-bearing or impact force in the environment has exceeded the resistance of the blister itself, the PET blister tray will rupture. In this case of use, PVC blister trays, although less rigid than PET, may be more suitable for this type of work environment.
