The so-called pull line (we called it pull line) is some undue line protrusions produced of the surface of blister packaging during the production . This line is absent on the mold.

At this time, what we need to do is to re-modify the Blister Packaging mold by reducing the mold height, increasing the roundness and adding additional pressure molds (we called it upper mold). When the pull line is too large, it will be regarded as a defective product and cannot be used for high-end blister packaging.

We should keep a good production environment and have professional engineers to produce it. Strictly control each step of the production.We meet different customer's needs and incorporate them into the design of each blister packaging.Our packaging design team can develop a fully customized blister packaging that meets your exact specifications.We make a variety of shape Plastic clamshell packaging and trays which will show your product in the best way!
