In China's dairy sector, the phenomenon of "assimilation" of product packaging is common. If you walk into the dairy section of a supermarket, you will see products with similar labels or packaging in different colors. In today's fierce market competition, making our products “unique†and “unique†will make the company invincible.
At this time, a new packaging concept - UNIFILL plastic thermoformed filling and packaging received everyone's attention, UNIFILL equipment can give the market a sense of freshness, the container produced is compact and attractive shape, can be "outside the box on the supermarket shelves. Out." In addition, the use of beautifully printed plastic packaging can make the product even more beautiful. The innovative product packaging provides a new marketing tool for Chinese food manufacturers. UNIFILL's packaging technology can be used for the formation and filling of liquid or semi-viscous products such as yogurt drinks, cream desserts, and hot filling of cheese and chocolate products.
The use of UNIFILL plastic thermoformed filled cheese avoids contact with cheese by hand and is easy to open and easy to eat. The product is hot liquid during filling and then solidified in a peelable PS/EVOH/PP composite packaging container.
Many European cheese manufacturers use this form of packaging because it is simple, easy to open, and can be made into a variety of cartoon images that children love.
UNIFILL's packaging is based on two proven technologies, namely plastic sheet thermoforming, filling, and sealing packaging systems, as well as in-mold blow molding devices that enable each package to have a distinctive shape.
The patented UNIFILL plastic thermoforming filling and sealing machine combines the above two technologies into one. Two rolls of sealable plastic film can be fed through a preheating unit. Each board can mold up to 15 products at a time, filling and sealing. Die-cutting is completed once. At the same time, composite plastics made of PS, PET, PP, and PE can be used on one device to meet the different opening characteristics of the product.
The specific production procedure is to first preheat the plastic web (single or double drums) and then thermoform in the closing and forming dies to produce the desired shape. After the product is filled in the molded cavity, the top is sealed. Finally, the equipment will form and cut the package in the final cutting die according to the desired design. In order to fill different shapes of products or make different shapes of containers, the molds of related equipment are easy to replace. The filling method can choose hot filling and ultra-clean filling. During the filling process, automatic monitoring can be carried out, and products that are not filled or defective can be rejected.
It is worth mentioning that packaging materials packaged with milk products are printed with good patterns in advance. When molding and sealing, the accuracy of positioning is particularly important, which puts a test on the accuracy of equipment operation. UNIFILL equipment adopts servo motor and computer control to ensure the stability and accuracy of equipment operation.
