1. Introduction of Blister Products:

Blister products are mainly made of high-quality PVC, PET, PP, PS, GAG, flocking and other plastic materials to produce high-end and various specifications of electronic blister packaging, stationery blister packaging, toy blister packaging , Blister packaging for hardware, blister packaging for food, blister packaging for daily gifts and crafts. Blister packaging is of high quality and low price, which can beautify your products and attract more customers.

Advantages of blister packaging:

1. Blister packaging can improve the price and image of the product itself, and also has the role of shaping and dissemination, which has a major impact on the company's brand image and popularity.

2. Blister packaging is also for the purpose of displaying and protecting products. Most of the packaged products are small commodities, which can be placed or hung on the shelves of supermarkets, so that your products can be perfectly displayed in front of customers to promote product sales.

3. Blister packaging is used for separation, shockproof and foiling purposes. Most of the packaged products are electronics, IT, industrial parts, toys, stationery, food, handicrafts, and cosmetics. It can package many and small products to make the product more integrated. Beautiful.

Second, blister packaging

Products mainly include: blister shells, trays, blister boxes, synonyms are: vacuum hood, blister, etc.

Blister products

Equipment

Blister packaging equipment mainly includes: blister packaging machine, blister forming machine, punching machine, sealing machine, high-frequency machine, folding machine.

Products

Packaging products formed by encapsulation can be divided into: insert card, suction card, double bubble shell, half bubble shell, half-folded bubble shell, triple-folded bubble shell, etc.

Raw materials

The raw materials of blister packaging are: PVC, PS, PP, PET, PETG and flocking, antistatic, conductive and other materials.

3. Production process

1: Mold making and processing: According to the requirements or sample specifications, first make a plastic mold. Under general conditions, plaster is used to make plastic packaging molds, but wood carving and metal carving products are also used as molds. Gypsum molds are made well. After that, let it dry naturally or completely, and then according to the specific conditions of the surface of the product, use 1-2 mm drills to drill many small holes in the low depressions that do not affect the appearance of the product. If it is a product such as a packaging box In addition, some small holes have to be drilled on the four sides so that the air can be drawn out during plastic production. After the holes are drilled in the mold, the gypsum mold must be hardened. The hardening method is to soak in a saturated alum saturated solution Then dry. [1]  

2: After the mold is processed and dried completely, install the mold into the upper iron plate of the vacuum chamber, then load the plastic sheet into the applicable size according to the size of the mold, and then put this sheet into the heating wooden cabinet to make it completely fixed , And then put the wooden cabinet and plastic sheet on the constant temperature furnace for softening treatment.

3: Put the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck the air in the vacuum chamber clean. After the plastic sheet cools, you can get the same concave packaging or process mold as the mold.

4: Blister packaging and finishing; trimming and finishing the produced products is the finished product, which can be sold after packaging.

Fourth, the price factor

Unit price of blister = product material cost + energy consumption + labor and transportation + profit

Energy consumption: Plastic blister is processed by heat, and the power consumption is relatively larger than other industries, roughly 8% of the cost of product materials: Plastic blister is mainly produced by machines, with less labor, roughly 10% of the material cost : According to the distance between the customer and the factory, profit: The net profit of the blister factory is generally very low, 12% -20%, depending on the payment period, the 30-day checkout is 14% Material cost: Comparison of product material cost calculation Complicated, the following data should first be clarified before calculation:

Raw material price: Determine what kind of material and grade of material to use according to the use of the product, find the lowest price supplier of this material Film thickness: Predict how thick the product must be made of film, according to the thickness and shape of each part of the molding Determine the number of layouts: According to the product size and shape, calculate how many molds can be arranged in one version. The dense packing will reduce the quality of the product, and the thinning will increase the material loss and increase the cost. Material loss rate: The main factor is the product shape , The number of products and the degree of adaptation of the external dimensions to the chassis of the blister machine, the more square the shape, the greater the output, the smaller the loss rate

Material cost calculation formula

Product material cost = 1 ton raw material price / 1 ton raw material finished product quantity

The number of finished products per ton of raw material = 1 ton of raw material length / (length of blister template + 4cm to 15cm stretched edge) X number of layouts X (100%-material loss rate)

1 ton of raw material length = 1 ton / material density / film thickness / width (width of plastic chassis)

Among them, material density (PVC is 1.36T / M3), blister chassis width (0.51-1.20M), template length and other four parameters are estimated by professional experience

V. Main features

1) Good protection.

2) Transparent and intuitive.

3) Easy to use.

4) Light weight.

Six, mold selection

Blister packaging molds generally have three types of gypsum mold, electroplated copper mold and aluminum mold

Gypsum mold: Gypsum is carved in a semi-wet state and then dried to form a mold. The cost of the plaster mold is low and easy to modify, but the precision of the plaster mold is not high enough, the surface is not smooth and fragile and not durable, so it is often used Pretend to be a kind of electroplated copper mold or some plastic molds that are not required to be produced in small batches.

Aluminum mold: It is made of aluminum ingots through machinery (lathe, milling machine, CNC, etc.). Aluminum molds have high precision, smooth surfaces and durable, but the price is very expensive. Aluminum molds are generally used in plastic products that cannot be achieved by copper molds with higher precision requirements.

Electroplated copper mold: After making a sample with a gypsum mold, electroplating a layer of copper shell is the electroplated copper mold. The cost is higher than the gypsum mold, but it is much cheaper than the aluminum mold. Because of its smooth and durable surface, low cost, electroplating Copper mold is the most commonly used plastic mold.
