Frequently Asked Questions and Solutions for Blister Packaging

What is a crystal point? How to solve the problem?

A crystal point is a point on the blister packaging material, which will seriously affect the appearance of the blister packaging product. The quality problem comes from the sheet supplier. The reason for this is that there are debris mixed in the material during the production of the sheet. The solution is to check the sheet before producing the blister packaging product.

What causes uneven thickness? How to solve such a problem?

The most common points of uneven thickness are shelves, sheets, temperature, etc. When the shelves are pressed on the blister packaging product, the position adjustment is very critical. If there is a misalignment or unreasonable placement, uneven thickness will occur.

The problem with the sheet is that the thickness of the sheet is not adjusted properly during the production process, so it will cause such quality problems. The temperature adjustment is also directly related, and the corresponding temperature should be adjusted according to different molds and different materials, otherwise unevenness will occur. The solution is to pay attention to the position adjustment of the shelf, the condition of the sheet, the negotiation with the supplier, and the temperature adjustment to the suitability of the sheet and the mold.

What is the pull line? How is it caused? How to solve it?
The pull line is a protruding line on the edge of the product that seriously affects the appearance of the packaging. The reasons for the generation are: related to the structural manufacturing of the blister mold, the controlled operation of the blister molding machine, temperature adjustment, and the shelf. The solution is mold quality control, machine and temperature parameter adjustment, shelf extrusion, etc.

What are water ripples and bubbles? How is it caused? How to solve it?
Water ripples and bubbles are watermarks and bubble points on the surface of the material. Such blister products will directly affect the appearance of the packaged items and reduce the appearance of the packaging. The generation of water ripples is related to the speed of film production. Bubbles are caused by excessively high temperatures during sheet production, mixed sheet production, or air infiltration during sheet production. Materials with bubbles can cause perforation and deformation of blister packaging products, making them defective products. The solution is to observe the quality of the sheets before purchasing or producing them.

What are scratches? How is this quality problem caused? How to solve it?
Scratches are scratch marks on the surface of blister products after they are produced. They are also a common quality problem in blister factories. The reason for this is that there are many manual processes in the production process, which are prone to collision and friction. The operation methods of punching and packaging personnel are the most critical links.
The solution is to handle the products with care, keep the workbench clean and hygienic, and have the staff wear gloves and other related matters, which can also effectively prevent scratches. Blister packaging products have many manual processes, so close attention must be paid to each link to avoid the production of defective products.
