advantage
1. New and beautiful appearance.
Because the label in the mold and the plastic parts are naturally integrated, they are deformed with the deformation of the bottle, so there will be no foaming, wrinkling and other phenomena. At the same time, the mold labeling printing is exquisite, can be laser, aluminum plating and other special effects treatment, so that the product packaging grade is greatly improved;
2. Anti-counterfeiting function.
The in-mold labeling system is relatively complex, reducing the possibility of fraud, which provides a very reliable means of brand maintenance for the user manufacturers of plastic packaging products that pursue quality, pursuit of quality and pursuit of brand;
3. Safe and environmentally friendly.
Ordinary labels should be labeled after the container is formed, and the in-mold label and the container molding are completed at one time, thereby preventing the contamination of the bottle body that may be caused by the labeling process. In addition, the in-mold label and the bottle body are completely integrated with the same chemical composition, and can be recycled together, and the recycling rate is high.
4. Not easy to fall off and damage
. The in-mold label is waterproof, oil-proof, mildew proof, acid and alkali resistant, and friction-resistant. It is not easy to be damaged under special conditions.
5. Side walls are reinforced.
The label is embedded in the side wall of the plastic container, which increases the extrusion strength of the side wall of the container by 20% so that the label does not separate when the container is warped and squeezed.
6. High efficiency and benefit.
The in-mold label and container molding is completed once, so that the packaging production speed is faster, and the filling line efficiency can be increased by 5% to 20% because the manual labeling method after filling is omitted, thus reducing the cost.
Labels can be changed without interrupting production.
Overall combined interest is significantly lower than ordinary labels and direct screen printing.
shortcoming
1. Production requires professional injection molding machines.
2. Film labeling requires professional printing machine.
In-die labeling Requirements for injection molding machines, molds, manipulators, and labels
The use of in-mold labeling requires a special structure of the mold. Mold labeling is an interlocking production system, injection molding machine, mold structure design and mold material, plastic raw materials, labels, manipulators, etc. need to be closely coordinated to complete. Because of this, in order to reflect the technology and integration capabilities of an in-mold labeling equipment supplier, the price of the entire set of equipment is also understandable. At the same time, we should also realize that these factors have increased the difficulty and cost of product counterfeiting to a certain extent, thus providing a reliable means of brand protection for regular user manufacturers.
In the mold labeling, injection molding machine, mold, manipulator and label four aspects constitute the mold labeling complete production system, the whole system put forward special requirements for each aspect, but also requires that they must have a good match between each other to ensure the smooth completion of the mold labeling process.
In-mold labeling requirements for injection molding machines, molds, manipulators and labels are: The injection molding machine used for in-mold labeling must have high stability, because it is the key factor to control the rate of defective products and production efficiency; The requirements for the mold material are to ensure that the mold cavity can firmly absorb the label when the label is adsorbed by static electricity, and the static electricity can be completely eliminated after the adsorption. In addition, when the mold is absorbed by moisture, it must also ensure that it does not rust; Label die cutting is very important, if the size is not accurate, will affect the appearance of the product; The precision of the manipulator is very high, and the label must be able to be accurately positioned in the mold.
