Slide blister means to pack the card and transparent blister together and does not need any packaging equipment while packing. The only thing the workers do is putting the blisters and cards in place. But the important things we must pay more attention are: 1. The size of card fits blister. The card and blister will change types if pack them tightly. If the blister made is too loose, the card will fall off easily. 2. Need to think about the weight of products.
