This plastic lid brings a better experience for product preservation

I remember when I was a child, I often needed to drink milk. The milk I drank included fresh milk in glass bottles and milk made with milk powder. According to the economic conditions and personal habits at that time, most of them drank milk powder. When the material prosperity was not enough, they were satisfied to drink milk powder!

Milk powder on the market is mainly packaged in tinplate and composite aluminum film bags. Generally, milk powder in tinplate with the same capacity is more expensive than that in bags. Besides the cost of tinplate is higher than that of composite plastic bags, the process cost of tinplate packaging is also higher.

After opening the package, because it is impossible to eat all the milk powder at one time, it needs to be re sealed at this time. For bagged milk powder, as it belongs to disposable packaging, the method I use is to fold the torn position several times, and then clamp the folded position with a clip. I believe many people have used this method. In addition, I can find a large bottle, put the whole bag of milk powder in it, and then screw the lid tightly. For canned milk powder, the plastic cover originally attached to the top of the tank can be directly used to buckle it on the top of the tank again, so as to achieve a relatively sealed state.

According to the experience of eating milk powder at that time, the effect of clamping the mouth of the bag with a clamp after opening the package of bagged milk powder was not ideal. Because of the poor sealing, the external air was easy to enter into the bag, which made the milk powder in the bag damp, oxidized, and even formed a large piece of milk powder, which reduced the taste and nutritional value of drinking. However, after opening the package of canned milk powder, the effect of using a clamp to clamp the mouth of the bag was not ideal, Using the plastic cap to compress the top of the can, the sealing is better than the re sealing method of the bagged milk powder, and the storage time of the milk powder is longer than that of the bagged milk powder, so the drinking experience of the canned milk powder is better than that of the bagged milk powder.

In the secondary preservation of canned milk powder, the key role is the secondary sealing rubber cover. This kind of plastic cover can be made into a circle or a square. It is widely used in the food industry, such as pet cans, canned nuts, potato chips, sandwich seaweed, eight treasure porridge, cheese and so on.

The sealing method of the plastic cover is very simple, that is to align the edge of the cover with the edge of the can top and press it down to complete the packaging. Although the packaging method is very simple, many manufacturers still use a lot of manpower to complete the work. But in the market, there has been an automatic equipment for this kind of gland packing method - Automatic lid applicator

Automatic lid applicator is a classic product of Guangzhou Utrust Packaging Equipment Co.,Ltd. It can realize automatic capping and capping, and is suitable for both round and square covers. Please see the following introduction:

You can watch the following mechanical operation video

Operation principle:

1. The rubber cover in the cover storage groove is sucked into the buckle cover groove by pneumatic suction nozzle;

2. The movement of the conveyor belt brings the can to the entrainment place;
3. The entrainment drives the jar to move, takes out the cover of the cover outlet and compresses it by the gland wheel;

4. The cover of different caliber can adjust the width of the clamp by adjusting the hand wheel, which only takes 5 minutes;
5. The height of the gland wheel can be adjusted by adjusting the hand wheel for the covers with different heights, which only takes 5 minutes



Parameters:
1. Capacity: 30-50 cans / min
2. Applicable bottle height: 60-200 mm
3. Applicable bottle diameter: 50-120mm
4. Working temperature: 0 ~ 45 ℃, working humidity: 35 ~ 85%
5. Working power supply: AC220V 50 / 60Hz
6. Total power: 0.65kw
7. Severe: 250kg (about)
8. Overall dimension: 2000 * 1000 * 1800mm

9. Air pressure: 0.6 ～ 0.8MPa; flow rate: 0.15m3/min
