In recent years, large-capacity bottled water has become popular in the market. Because it not only has the function of drinking regular drinking water, but also can realize the function of drinking from a water dispenser, large-capacity bottled water can be seen everywhere in many homes, offices, public places, etc. . You can see that these large-capacity bottled water bottles have a sticker on the top. The role of this small sticker cannot be underestimated. Next, Mingsanfeng Cap Mold Co., Ltd will talk to you about the knowledge of film on bottle caps.
Films mainly perform three functions on large-capacity bottled water packaging:
First, its primary function is to prevent theft. Once the film is torn off, it cannot be reattached, which means that the bottle of water has been opened and there is a risk of contamination.
The concave platform in the middle of the second largest-capacity bottled water is formed by the top of the water dispenser to form a water outlet, so it has high hygiene requirements. Without this layer of film, the position of the concave platform of bottled water will be damaged during processing, transportation, storage and sales. Accumulation of dust and contamination.
Third, the pattern on the film can enhance the visual effect of the bottled water, make the bottled water more beautiful in appearance, and also provide a rich advertising effect.
After explaining the meaning and function of the film above, let me explain to you the fully automatic film production process of Mingsanfeng Cap Mold Co., Ltd:
After the bottle caps are compression molded and ring-cut, they will be transported to the transfer warehouse under closed conditions to wait for lamination. The transfer warehouse is connected to a climber, and the bottle caps will be transported from the climber to the capping plate. After rotating the cap sorter, all the bottle caps are arranged neatly and the openings are facing downwards.
At this time, the film application begins. The suction cap trays are grouped to suck up the bottle caps and send them to the die head. The roll film will be straightened and transported in conjunction with the second group of pressure heads for cutting and stamping. In this way, the cap film plays a role in heating and pre-pressing. It sticks to the bottle cap. At this time, the adhesion of the cap film is still very low and has not reached the normal factory requirements. We still need to perform a second pre-pressure. The bottle caps with the film attached will continue to be transported forward to reach the third set of pressure heads. This set of pressure heads It is also in a high-temperature state. The high-temperature pressure head will press the cap film on the bottle cap again for about 0.1 seconds, so that the thin hot melt adhesive on the inner surface of the cap film will fully fit and adhere to the surface of the bottle cap. The force will reach the standard.
The filmed bottle caps continue to be transported forward, and then packaged through counters. The quality inspector will conduct a series of tests on the film quality, including film position, film adhesion, etc. After passing the test, they can be arranged to be stored in the warehouse and delivered to the customer. On hand.
