How dairy companies use blister packs

Recently, the market is very popular milk powder dry food, several products introduced in the market are used blister packaging. According to the relevant personnel of the equipment department of Mengniu Dairy Group, the sales of “Mengniu Brand” milk tablets in the southern market are in short supply, and it is even less likely to supply the northern market. Therefore, Mengniu's milk tablets cannot be seen in the northern markets. At present, our demand for blister packaging equipment is very high and we are currently organizing tenders.

Application of aluminum foil printing

The most common structures for blister-packed aluminum foil are: Varnish/Ink/Pre-paste/Aluminum foil 20 micron/Heat sealant. All aluminum foils on the market use one-color or two-color printing. Multi-colored aluminum foils can enhance brand quality and improve product quality. Aluminum foil can also use anti-counterfeit printing effects to ensure the market value of the product. In addition, aluminum foil can also be printed by date to enhance the humanized design of the product. As a non-pharmaceutical blister package, it should pay more attention to improving the added value of the product and make it stand out among many similar products.

Special slice cutting system

Most of the shape of the milk tablets currently on the market is a plain tablet having a diameter of about 20 mm and a thickness of about 7 mm. Its shape is so large that the production speed is largely affected by the feeder.

Roller-type feeder: This feeding system is suitable for rolling products such as sugar-coated tablets, soft capsules, and pellets. The advantage is that the price is low, but the disadvantage is that because of the need to brush the tablet into the blisters, there will be a certain amount of abrasion of the tablet, and the speed is slower, and the leakage rate is relatively high.

Orbital feeders: Arrange medicines in orbit, down to the bubble. This type of material feeding method has a wide range of applications. The disadvantage is that sometimes it cannot be applied due to the shape and tolerance of the product.

Vacuum drum type feeder: It is actually a type of track feeder, which is generally used for double aluminium blister packaging, combined cutting and other special requirements, the price is relatively expensive.

Alward-type feeders: Generally used for double aluminum packaging, the use of less, the price is relatively expensive, the speed is relatively low. COMBFILL type feeder: It is generally applicable to special-shaped sheets, soft capsules or other products with relatively large tolerances. It can often deal with products that cannot be handled by other feeders. It is also very convenient when replacing specifications. The disadvantage is that the price is very expensive.

Taking Mengniu Dairy's dried milk tablets as an example (product specification: cylindrical; diameter: 20mm; thickness: 7mm; plate type: 65*2mm), the production speed of several different blister packaging equipments is introduced.

Germany Bosch CN25 blister packaging machine

BOSCH equipment experts recommend Mengniu to change the plate size to 60*112mm. This type of plate design will be the most economical and reasonable. The CN25 equipment provided by BOSCH will use track-type feeders and blister packs according to the modified plate size. The board is molded once with three boards and the maximum output is 183 boards/minute.

The technical parameters of the equipment:
Maximum output: 250 pcs/min Max. punching cycle: 250 cc/min Max. travel speed of sheet: 11 m/min Step length: 180 nn/step Maximum forming depth: 12 mm
The largest version: 90*145mm
Minimal version: 30*60mm

Italian IMA company TR135 blister packaging machine

Equipment expert tips: If you do not consider the cutting speed, without changing the specifications of the plate can reach 180 to 190 boards / minute or more (each forming 2 boards, molding 95 times per minute). This type of product should be equipped with an orbital feeder equipped with a dust removal and debris attachment. The specific feeding speed depends on the tolerance of the milk tablets and the nature of the surface properties. According to the nature of the milk products, in order to achieve a relatively high cutting efficiency, it is recommended to control the temperature and humidity of the production environment. If necessary, consider the following conditions. Vibration track attachments or special materials are used for track surface treatment.

The technical parameters of the equipment:
The largest molding plate area: 135*135mm
Maximum punching speed: 240 board/min Max. molding speed: 95 times/minute Blister board molding range:
Width: 30mm~88mm
Length: 60mm~135mm
Depth: 3mm~12mm
