The mould processing of trifold/sliding card packaging

Vacuum Forming & Machine

The first thing is to know the blister forming principle —- Vacuum forming technology.

It is a kind of thermal processing method, the thermoplastic sheet is cut into a certain size, after heating and softening the plastic sheet, with the help of the two sides of the sheet atmospheric air pressure difference and mechanical pressure to make the sheet deformation, and then cover on the surface of specific mould. After cooling deformation, and trimming to complete the process of plastic blister tray.

Vacuum therforming progress

There have 2 kinds of main blister packing thermoforming machines, the one is negative pressure blister thermoforming machine, through the way of negative pressure of air to achieve vacuum, so that the plastic sheet attached to the blister mould.

And the other one is positive and negative pressure thermoforming machine, through the way of pressure and vacuum, then form a strong pressure difference on both sides of the plastic sheet, so as to soften the plastic sheet forming.

According to the blister inner tray forming way, the common blister packing machines is the negative pressure machine.

Technique of Vacuum forming

To produce a good quality blister packaging, there need to pay special attention to the two points: blister forming mould and processing technology.

Technique of Vacuum forming

Mould Styles of Blister Tray

The mould plays a very important role in the quality of the custom blister packaging. Usually, there have the plaster mould, cooper mould and hardware mold for blister forming molds.

Plaster mould is easy to make, making time is also short ( about 2-4 days). It is conducive to modification of product packaging. Compared with another molds, its cost is lowest. Due to the original color of plaster mould, the transparency of blister made by plaster mould is less than the blister transparency made by other mould. So it mainly applicable to the sample confirmation and low requirements of product packaging transparency.

Cooper mould is metal molds made on the basis of plaster molds, which are relatively durable. The thickness of blister cooper mold is about 0.5-0.8mm, and the making time is about 5 days ( including the plaster mould making time). The surface of copper mould is smooth, so the appearance and transparency of the blister produced are good. Also, its mold cost is relatively low, so that it is the most commonly used blister tray insert forming mold.

Aluminum mould needs to be based on 3D design or product sample, through CAM and other programming software programs, completed by CNC machine tool processing The precision of aluminum mold is very high, the contour and Angle of the blister packagings produced are relatively beautiful. Relative to the other two molds, its price is the highest, but its durability and production efficiency are higher, time saving and electricity saving, and the rejection rate is very low. This mold is suitable for packaging with high appearance and size requirements. It is the first choice for mass production and high requirements of blister production.

Folding process of sliding blister card packaging

After we make the plastic sheet into the shape we want, we can start to fold the edge. Because the material is not easy to fold, what you see the trifold blister is the result that we use sliding blister machine to fold it many times. The thicker material, the more difficult to fold it. Tell us your product size, then we can suggest the material for you. According to your detailed requirements, we can give you some professional packaging advice.

What is trifold/sliding blister card packaging?

The sliding blister packaging consists of two parts, plastic blister + paper card. The blister needs to fold the three sides of the blister to the back with a folding machine, so that in the next packaging process, the paper card can be inserted into the folding to form the sliding blister packaging.


We usually use PVC or PET materials to make sliding blister. PET material are food-grade and environmentally friendly material, it can use to pack the food. PVC materials are not environmentally friendly materials, and are usually used for packaging various tools or toys.


In addition, we can accept customized sliding blister packaging thickness range is between 0.3-1 mm. You can choose a suitable thickness according to the size and weight of your product. If you have no idea about this, contact us and we can give you some suggestions.

Thickness of the paper card

Usually we will use gram to present the paper’s thickness. For one square meter paper, the weight is their thickness. For example, 350g single side coated board means that the weight is 350g for one square meter C1S.

350g paper card is the material which was used most frequently for the product. Some client will choose 300g paper card because their product is very light and the client wants to save the cost. But we do not suggest the clients to choose 300g paper card due to it is weak thickness. It is not strong enough to protect product when the products falls from high place.


Mounting means that we combine 2 pieces of paper card into one paper card, it is called mounting paper or mounting board. 250g amounting (total 500G) thickness is thicker than 350g paper card. If you want to make your product look more high-grade and stronger to pack your product, 500G paper card is a good choice for clients. It can be full color printing on both sides.


Craft of the paper card

CMYK printing or single color on one side or on both sides for paper card.

Product picture, product Instructions, company information… can be printed on the paper card .

Embossing can emphasize and highlight the important parts of printing design like logo and slogan. When you touch the embossing part, it is outstanding obviously.


Hot stamping/sliver hot stamping is the process that shows a sense of metal and a stronger sense of three-dimensionality through the change of the hot stamping plate. The color is brighter, but price for this craft is expensive. So we suggest that you can apply for some words that you want to emphasize it.
