Reasons for alu plastic plate bending:

Plastic heating molding will produce different shrinkage (PVC horizontal+, PVC vertical -). PTP aluminum foil will not shrink after heating.

The influence of the downward force of the blanking die of the aluminum plastic blister equipment.

The influence of the arrangement (horizontal and vertical) of the drug plate mold.

How to reduce and improve bending??

Draw strips in the middle of the alu plastic plate to block the influence of plastic shrinkage.

Independent  "die cutting grid  line" is applied to the  independent  blister of aluminum plastic plate to reduce the influence of shrinkage.

Change the arrangement direction of the medicine plate die cutting, arrange the medicine plate die horizontally, and arrange the capsules at 45  °.

A. Fish bone design of "strip drawing" on alu foil

B.  Independent  mesh  grinding  tangent  line  is  applied  to  aluminum plastic blister。

C. Change the horizontal and vertical arrangement of the charge plate to reduce the bending and facilitate the packing.
